WEBVTT 00:00.040 --> 00:04.960 We simply printing out a message saying that enemy one died instantly. 00:04.960 --> 00:09.200 Instead of printing out message, we need to play the death animation clip. 00:09.200 --> 00:14.480 So if I select my enemy one GameObject in the hierarchy and then move over to animator tab. 00:14.520 --> 00:17.880 As you can see, we have the Death animation clip. 00:17.880 --> 00:20.280 So we need to trigger this death parameter. 00:20.640 --> 00:25.040 So we do know that if we trigger it it's going to play that animation clip. 00:25.040 --> 00:31.680 So what we will do we will open up our enemy one script and we will go to our update function instead 00:31.680 --> 00:38.560 of doing over here we don't want to check every single frame or basically if we just call this die function. 00:38.560 --> 00:43.000 So inside this die function we basically want to trigger that parameter. 00:43.000 --> 00:45.720 So let's trigger that parameter first. 00:45.720 --> 00:48.240 And after that we're going to take a look on that. 00:48.480 --> 00:53.720 So firstly we need a reference of this animator component of this enemy one game object. 00:53.720 --> 00:55.440 And we do know that we have it. 00:55.440 --> 00:59.920 So we will simply open up enemy one script and let's go to die function. 00:59.920 --> 01:01.930 And inside this function. 01:01.930 --> 01:05.810 After printing out message, I want to trigger that parameter. 01:05.810 --> 01:11.570 And we do know that as soon as we trigger it, it's going to play the death animation clip, which we 01:11.570 --> 01:12.610 saw earlier. 01:12.610 --> 01:18.450 So we will go to animator component, and we're going to use this set trigger function in order to trigger 01:18.450 --> 01:19.410 that parameter. 01:19.570 --> 01:21.970 Why are we using this trigger function. 01:21.970 --> 01:28.650 Because if we move over to unity and we can notice that this parameter is a trigger parameter. 01:28.650 --> 01:33.450 So firstly we are moving over to this animator component of this anime one game object. 01:33.450 --> 01:36.890 And after that we are just using this set trigger function. 01:36.890 --> 01:42.610 And inside the inside this brackets in quotation it's going to take the parameter name. 01:42.610 --> 01:44.410 So the parameter name is death. 01:44.410 --> 01:47.690 So we need to pass the death and make sure you spell it correct. 01:47.690 --> 01:50.010 Else it's not going to work at all. 01:50.010 --> 01:52.570 And after that we will close that off with semicolon. 01:52.570 --> 01:55.890 And now we're going to press down Ctrl S to save our escape. 01:56.010 --> 02:02.620 And if we move over to unity and then we loses all of our health, you will see this anime one game 02:02.660 --> 02:03.180 object. 02:03.180 --> 02:07.060 Just gonna play the death animation clip over again and again. 02:07.100 --> 02:07.540 Why? 02:07.700 --> 02:13.220 Because if we move over to our update function in update function, we are calling the die function 02:13.220 --> 02:16.460 and we do know what we're doing inside that function. 02:16.460 --> 02:22.700 So this type function just going to call over again and again means the death animation clip just gonna 02:22.700 --> 02:24.780 play over again and again. 02:24.820 --> 02:25.740 Let me show you. 02:26.100 --> 02:32.900 So if I move over to unity and then click on this play button, you will see that once this anime one 02:32.900 --> 02:40.780 just gonna loses all of his health, uh, than this death animation clip just gonna play over again 02:40.780 --> 02:43.540 and again of this anime one game object. 02:43.540 --> 02:45.020 So let me show you first. 02:45.020 --> 02:49.180 So let's get in attack range and try to damage this anime one. 02:49.180 --> 02:53.340 So if I damage it we can see that now it's died. 02:53.380 --> 02:59.300 And but the problem is that as you can notice, the death animation clip just playing over again and 02:59.300 --> 02:59.700 again. 02:59.740 --> 03:00.100 Why? 03:00.260 --> 03:06.120 Because if we move over to a script and then go over to update function, we do know that this update 03:06.120 --> 03:08.080 function runs every single frame. 03:08.080 --> 03:12.680 So every single frame we are checking if the max cell is less than or equal to zero. 03:12.720 --> 03:18.000 If that is the case, then we are calling the die function and die function, simply triggering that 03:18.000 --> 03:21.800 parameter which is dead, and it's going to trigger every single frame. 03:21.840 --> 03:25.320 Since we're calling this die function inside this update function. 03:25.320 --> 03:31.040 So that's why we're going to remove this from here to our Takedamage function. 03:31.040 --> 03:36.000 Inside this Takedamage function we're going to move it in inside over here. 03:36.280 --> 03:39.720 So we will get out of play mode and let's remove that. 03:39.720 --> 03:41.400 So I'm going to get out of play mode. 03:41.400 --> 03:43.320 And let's move over to our scape. 03:43.320 --> 03:45.600 And let's move over to update function. 03:45.600 --> 03:47.760 And let's remove this over here. 03:47.920 --> 03:51.560 Instead of doing that we're going to call the die function here. 03:51.560 --> 03:53.480 So let's call the die function here. 03:53.760 --> 03:55.920 So we also check in right over here. 03:55.920 --> 03:57.560 If the max health of enemy. 03:57.680 --> 04:03.090 If it's less than or equal to zero then what we're doing we with we just stop taking. 04:03.130 --> 04:03.650 Damage. 04:03.650 --> 04:09.490 So we also need to call the die function once our enemy one just loses all of his health. 04:09.490 --> 04:11.410 So we're going to call the die function here. 04:11.570 --> 04:14.930 And let's make first bracket and then close that up with semicolon. 04:14.930 --> 04:18.010 And now we're going to press down Ctrl S to save our escape. 04:18.010 --> 04:23.210 And now that death animation clip not gonna play over again and again. 04:23.250 --> 04:29.730 So since the Takedamage function we're not calling inside our update function, which update function 04:29.730 --> 04:30.970 runs every single frame. 04:30.970 --> 04:37.770 So that's why that function, basically that death parameter just triggering over again and again. 04:37.770 --> 04:40.250 And we just removed it totally by now. 04:40.250 --> 04:42.370 And it should be fine by now. 04:42.370 --> 04:43.650 But let's have a look. 04:43.650 --> 04:45.570 So I'm going to select my console tab. 04:45.570 --> 04:47.450 And let's click on this play button. 04:47.450 --> 04:52.610 And we're gonna notice a strange things underneath our enemy one script. 04:52.610 --> 04:53.650 You will see that. 04:54.610 --> 05:00.810 So just wait a little moment and just wait a moment. 05:00.810 --> 05:06.580 So if we get in attack range and then attack one, we can see the maxhealth is now two. 05:06.620 --> 05:10.740 And if we attack one more time, maxhealth is became one. 05:10.740 --> 05:14.340 And if we attack one more time, Maxhealth is now zero. 05:14.340 --> 05:20.380 But the problem is that if I pause my game and then move over to my console tab, we cannot able to 05:20.380 --> 05:22.020 see that enemy one died. 05:22.060 --> 05:23.900 Messages gets popped up. 05:23.940 --> 05:28.420 Even though our max health of this enemy one GameObject reaches zero. 05:28.660 --> 05:31.700 So it's still that message just not getting pop up. 05:31.700 --> 05:40.020 But if we attack one more time, uh, time on top in this, uh, basically, if we attack on this enemy 05:40.060 --> 05:43.540 one GameObject, then you will see that message just gonna pop up. 05:43.540 --> 05:47.260 So I'm going to click on this pause button to unpause my game. 05:47.260 --> 05:48.140 And let's have a look. 05:48.140 --> 05:52.500 If I just attack one more time and now we can see the message. 05:52.500 --> 05:53.540 So sorry. 05:53.700 --> 05:56.500 If we attack we can see the message just gets pop up. 05:56.500 --> 06:01.580 If I pause my game and then move over to console tab, we can see now buy now. 06:01.790 --> 06:04.470 And you may want that message just gets pop up. 06:04.470 --> 06:05.870 So basically what we're gonna do. 06:05.950 --> 06:09.270 Instead of checking with zero we're going to check with one. 06:09.270 --> 06:10.630 So that is the thing. 06:10.630 --> 06:14.790 So we will get out of play mode and let's move over to our script. 06:14.790 --> 06:18.070 Instead of checking zero we're going to check with one. 06:18.070 --> 06:20.990 And now it's gonna work as fine. 06:20.990 --> 06:22.670 It's gonna work fine by now. 06:22.670 --> 06:23.750 So let's have a look. 06:23.750 --> 06:26.590 So we're going to press down Ctrl S to save our script. 06:26.590 --> 06:28.590 And now let's move over to unity. 06:28.870 --> 06:31.270 So it should work fine by now. 06:32.790 --> 06:34.030 So let's have a look. 06:34.030 --> 06:40.990 So as soon as our maxhealth of this anime one just gonna reach zero, then that message just going to 06:40.990 --> 06:43.470 pop up since we just checking with one. 06:43.470 --> 06:44.870 So that is the reason. 06:44.870 --> 06:47.790 So we gotten back and we just got it fixed. 06:47.790 --> 06:52.190 So let's click on this play button in the top in order to play our game. 06:52.190 --> 06:54.150 And let's take a look on this. 06:54.150 --> 06:56.910 So as soon as this enemy one just lose. 06:57.230 --> 06:59.830 Enemy one just gonna lose all of his health. 06:59.910 --> 07:06.120 Then message just gonna pop up underneath our control tab says enemy one died and then it's going to 07:06.120 --> 07:09.440 play that enemy one, that animation clip. 07:09.440 --> 07:17.760 So by so if I attack three times one, two and three, we can see that if we move over to our console 07:17.760 --> 07:21.560 tab, we can see enemy one died, message just gets popped up. 07:21.560 --> 07:27.240 And also the parameter just gets triggered which is playing the death animation clip. 07:27.240 --> 07:34.560 As soon as this enemy one just get, uh, loses all of his health because if it loses all of his health, 07:34.560 --> 07:36.840 as you can see, we're checking over here. 07:36.880 --> 07:38.720 Then we're calling the die function. 07:38.720 --> 07:44.280 What die function simply doing is firstly printing out the message in the console says enemy one died, 07:44.360 --> 07:45.720 as you can notice. 07:45.720 --> 07:51.000 And after that we're just going over to animator component and we're just triggering that parameter 07:51.000 --> 07:56.680 simply we're just moving over to this animator component of this enemy one game object and then just 07:56.680 --> 07:58.360 triggering this state parameter. 07:58.360 --> 08:04.300 And we do know that if we trigger it, we can see that animation just playing over again and again. 08:04.460 --> 08:10.740 But the problem is that if we attack on this enemy one game object, still this enemy one just taking 08:10.740 --> 08:14.060 damages and it's playing the death animation clip. 08:14.060 --> 08:15.900 So we need to stop doing that. 08:15.900 --> 08:21.340 So basically what we have to do, we need to disable the collider of this enemy one game object. 08:21.340 --> 08:27.180 And we do know that if we disable the collider of this enemy one game object, it's not going to detect 08:27.180 --> 08:28.220 any collision. 08:28.220 --> 08:34.540 So it's gonna not gonna take any damage anymore on that takedamage function. 08:34.540 --> 08:36.220 Not gonna call at all. 08:36.380 --> 08:43.740 So basically we need to disable this box Collider 2D of this enemy one, basically this Collider 2D. 08:43.740 --> 08:45.300 So we need to disable that. 08:45.300 --> 08:48.820 So this enemy one not gonna detect any collision. 08:48.820 --> 08:50.380 So let's get out of play mode. 08:50.820 --> 08:57.620 To disable that we need a reference of this box Collider 2D component of this enemy one game object. 08:57.700 --> 09:01.060 Then we can just disable that so we will open up. 09:01.060 --> 09:07.270 But the problem is that if we go ahead and then click on this play button, as soon as we disable this 09:07.270 --> 09:10.630 box Collider 2D manually, you will see this. 09:10.670 --> 09:11.470 Play this. 09:11.470 --> 09:14.230 Sorry, sorry really sorry. 09:14.230 --> 09:18.030 This anime one just gonna fall down due to our gravity. 09:18.030 --> 09:20.990 So if I just manually disable this box collider. 09:20.990 --> 09:26.750 So if I select my anime one GameObject in the hierarchy, then go over to Inspector, then Box Collider 09:26.750 --> 09:29.750 2D and then uncheck basically disable that. 09:29.790 --> 09:34.830 Well, as you can see, as soon as we disable it, it just passes through this ground. 09:34.830 --> 09:35.230 Why? 09:35.270 --> 09:39.470 Because uh, that collider just not detecting any collision. 09:39.470 --> 09:42.750 So that's why it just falls through this ground. 09:42.750 --> 09:48.790 So what we need after disabling this box Collider 2D, we need to set the gravity scale to zero. 09:48.790 --> 09:55.070 So if we move over to this rigidbody 2D component of this animation game object and and then move over 09:55.070 --> 09:58.110 to gravity scale, we can see we set it to three. 09:58.110 --> 09:59.470 So we're gonna set it to zero. 09:59.470 --> 10:01.830 So it's not gonna fall down at all. 10:01.830 --> 10:06.920 So we need a reference of this rigid body 2D as well as this box collider 2D. 10:06.960 --> 10:08.840 Then we can just set that up. 10:08.960 --> 10:11.320 So let's get out of play mode. 10:11.320 --> 10:14.680 And let's open up anime one script by double clicking on it. 10:14.680 --> 10:19.080 And let's go to the top of our class and let's declare those variable. 10:19.120 --> 10:21.840 Basically we need to graph reference of those. 10:21.840 --> 10:25.280 So the first thing we're gonna grab our box Collider 2D. 10:25.440 --> 10:30.480 So let's make a private uh the component we're looking for is a box Collider 2D. 10:30.480 --> 10:34.400 So we're going to type that and let's call it something like Box Collider 2D. 10:34.560 --> 10:36.400 And it doesn't need to be public. 10:36.600 --> 10:39.480 We're gonna grab the reference in this start function. 10:39.480 --> 10:40.280 So that's why. 10:40.600 --> 10:46.000 And the second component or the reference we looking for is our rigidbody 2D. 10:46.000 --> 10:47.880 So we're going to create a private. 10:47.880 --> 10:51.240 And the component we're looking for is a rigid body 2D. 10:51.240 --> 10:54.640 And we can call this one RB short for rigid body. 10:54.680 --> 10:58.440 You can simply say and now let's move over to this start function. 10:58.440 --> 11:01.440 So this start function get call in the start of the game. 11:01.440 --> 11:04.130 So in the start of the game we need to get the reference. 11:04.130 --> 11:10.210 Basically we need to take this rigidbody 2D as well as this box collider 2D component of this enemy 11:10.250 --> 11:11.330 one game object. 11:11.330 --> 11:12.410 So let's do that. 11:12.690 --> 11:16.450 So firstly we're gonna grab the reference box Collider 2D. 11:16.810 --> 11:18.650 Uh you can just do it. 11:18.690 --> 11:24.250 Uh, you don't need to, uh, make it in order in a order, certain order. 11:24.250 --> 11:26.490 You just make it wherever you want. 11:26.530 --> 11:29.890 Inside this start function, it doesn't need to be in order. 11:30.290 --> 11:35.330 So firstly, we want to grab the reference of our you can simply say box Collider 2D. 11:35.330 --> 11:36.330 So I'm going to type this. 11:36.330 --> 11:40.370 This dot GameObject basically means it just referencing itself. 11:40.530 --> 11:44.690 And we're going to use this dot get component in order to get the component. 11:44.690 --> 11:46.450 And we need to make these arrows. 11:46.450 --> 11:50.490 And inside these arrows we need to pass the component that we're looking for. 11:50.490 --> 11:52.730 So we're looking for our box Collider 2D. 11:52.730 --> 11:57.170 So we're going to type this box Collider 2D and then make this first bracket. 11:57.170 --> 11:59.810 And now we're going to close that up with semicolon. 11:59.810 --> 12:03.620 And now what we're going to do we're going to store this box Collider 2D component. 12:03.820 --> 12:06.420 Uh, basically we're just using this dot GameObject. 12:06.420 --> 12:08.780 Basically it's just referencing itself. 12:08.780 --> 12:12.780 So the animation script is attached to this anime one game object. 12:12.780 --> 12:18.100 So this GameObject, they're basically referencing this anime, one game object itself. 12:18.100 --> 12:22.100 And we're using Dot get component in order to create the component. 12:22.100 --> 12:24.980 So now we have this box Collider 2D component. 12:24.980 --> 12:29.620 As you can see in the in inside our start function. 12:29.620 --> 12:35.900 As you can see now we have it and we're going to store it into this box Collider 2D variable that we 12:35.940 --> 12:38.540 created up here as you can notice. 12:38.540 --> 12:43.940 So after taking that we're gonna store it into this box Collider 2D variable. 12:43.980 --> 12:45.700 Let's set equal to this. 12:45.740 --> 12:46.900 Basically what we're doing. 12:46.900 --> 12:51.740 We simply just getting this box collider 2D component of this anime one game object. 12:51.740 --> 12:58.620 And then we're storing that into this box Collider 2D variable we created up over here as you can see. 12:58.820 --> 13:01.620 And we're gonna do the same thing with this rigid body. 13:01.700 --> 13:03.350 So we're going to do the same thing. 13:03.710 --> 13:06.670 So what we will do we're going to store it into this RB. 13:06.710 --> 13:12.190 So we will set RB equal to this dot GameObject which is referencing itself. 13:12.310 --> 13:15.310 And the component we're looking for is a component. 13:15.310 --> 13:15.830 Sorry. 13:15.870 --> 13:18.030 We need to type this dot get component. 13:18.030 --> 13:21.110 And the component will be looking for is a rigid body 2D. 13:21.110 --> 13:23.270 So we're going to type this rigid body 2D. 13:23.310 --> 13:26.790 And let's make this first bracket and then close that up with semicolon. 13:26.990 --> 13:32.270 So we basically just grabbing this rigid body 2D component of this enemy one game object. 13:32.270 --> 13:40.830 And after that we storing that into this RV, that RV variable which is a rigid body 2D variable or 13:40.870 --> 13:46.310 a container type, you can simply say you can assume that we're storing into this RB. 13:46.550 --> 13:49.630 And we also taking our box collider 2D component. 13:49.630 --> 13:53.110 And we're storing into this box Collider 2D variable. 13:53.110 --> 13:55.990 As you can see inside our start function. 13:55.990 --> 14:00.510 Now we have it this box Collider 2D as well as this rigid body 2D. 14:00.550 --> 14:03.050 And now we are ready to set that up. 14:03.050 --> 14:06.530 So let's move over to our die function. 14:06.530 --> 14:07.090 Where are we? 14:07.130 --> 14:08.450 Doing so over here. 14:08.450 --> 14:11.170 As you can see we're triggering the parameter. 14:11.170 --> 14:17.450 So what we're going to do now over here uh firstly we will disable our box collider 2D. 14:17.610 --> 14:20.810 But before we disable let's set the gravity scale to zero. 14:20.810 --> 14:22.330 So we will go to RB. 14:22.370 --> 14:24.170 RB basically means rigid body. 14:24.170 --> 14:28.010 We just going over to that and we're going to access the gravity scale. 14:28.210 --> 14:30.770 And we're going to set equal to zero f. 14:30.810 --> 14:32.930 And let's close that up with semicolon. 14:32.930 --> 14:38.850 So we simply just moving over to this rigid body 2D component of this anime one game object and then 14:38.850 --> 14:41.490 accessing this gravity scale right over here. 14:41.490 --> 14:43.330 And we're setting equal to zero. 14:43.370 --> 14:49.370 As you can see now this anime one game object not going to fall down at all. 14:49.370 --> 14:56.410 And we also need to disable this box Collider 2D once this anime one game object loses all of his health. 14:56.610 --> 15:02.050 And so after setting gravity to zero, we're gonna disable that box Collider 2D. 15:02.170 --> 15:07.620 So we will go to Box Collider 2D where we store it, and then we're going to use the start. 15:07.620 --> 15:10.180 And then we're going to use this dot enable. 15:10.180 --> 15:12.300 And we can set equal to false. 15:12.340 --> 15:16.020 Set equal to false basically means we just disabling that. 15:16.380 --> 15:21.060 Or you can simply unchecking or checking if you set it to true something like that. 15:21.060 --> 15:24.340 It's basically means checked means you just setting it to true. 15:24.700 --> 15:28.020 Uh or you just enabling your box collider 2D. 15:28.060 --> 15:32.900 But if you set dot enable to false basically means you just disabling that. 15:32.900 --> 15:38.380 Or you can assume that we just unchecking or disabling this box Collider 2D. 15:38.620 --> 15:42.900 So as soon as our enemy GameObject just gonna loses all of his health. 15:42.940 --> 15:46.780 Firstly, we printing out the message in the console tabs enemy. 15:47.420 --> 15:53.260 As you can see, after that we playing the anime Death animation clip, and then we setting the gravity 15:53.260 --> 15:54.300 scale to zero. 15:54.300 --> 15:59.380 And after that we just setting box collider 2D dot enable to false. 15:59.380 --> 16:02.460 Basically we just disabling our box Collider 2D. 16:02.580 --> 16:05.670 So it's not gonna take damage after. 16:05.670 --> 16:09.430 Once our enemy won, game object loses all of his L. 16:09.430 --> 16:12.590 So it's not going to check for any collision at all. 16:12.590 --> 16:16.750 Once our box collider 2D enable enabled to false. 16:16.870 --> 16:19.910 And now we're going to press down Ctrl S to save our script. 16:19.910 --> 16:21.590 And let's move over to unity. 16:22.030 --> 16:26.310 So as soon as this enemy one GameObject just loses all of his L. 16:26.350 --> 16:31.430 Firstly, we're setting the gravity scale to zero, so it's not going to fall down at all. 16:31.430 --> 16:34.110 And after that we disabling the box Collider 2D. 16:34.110 --> 16:40.190 So it's not going to detect any collision means this enemy game object just gonna be fine. 16:40.190 --> 16:41.070 So let's have a look. 16:41.070 --> 16:45.110 So I'm going to click on this play button in the top in order to play my game. 16:45.270 --> 16:47.270 And let's have a look on this. 16:47.270 --> 16:55.630 So as soon as this enemy one enemy one GameObject Maxhealth hits zero, you will see that that animation 16:55.630 --> 16:57.590 just gonna play right away. 16:57.750 --> 17:04.400 So let's get in attack range and let's attack on this enemy one, two and three we can see. 17:04.440 --> 17:11.800 And now if we just, uh, attack, we cannot see this enemy one just playing the death animation clip 17:11.800 --> 17:12.400 by now. 17:12.440 --> 17:12.880 Why? 17:13.080 --> 17:17.760 Because if we select our enemy one in the hierarchy, then go over to Inspector. 17:17.760 --> 17:20.720 We can see we just uncheck the box Collider 2D. 17:20.720 --> 17:25.640 So that's why this enemy one not detecting any collision at all. 17:25.640 --> 17:31.480 And also we can see if we move over to this rigidbody 2D component, we can see that we just set it 17:31.480 --> 17:33.520 to zero gravity scale to zero. 17:33.560 --> 17:35.840 As you can notice right over here. 17:36.120 --> 17:38.800 So I hope you get the idea that how you can do it. 17:38.800 --> 17:43.720 And after some period of time we also need to destroy this enemy itself. 17:43.720 --> 17:45.280 So let's get out of play mode. 17:45.280 --> 17:45.760 For that. 17:45.760 --> 17:48.160 We're gonna open up our enemy one script. 17:48.160 --> 17:54.000 So let's open that up by double clicking on it and let's move over to die function right over here. 17:54.000 --> 17:56.880 So after some period of time we need to destroy. 17:57.080 --> 18:00.680 And in order to destroy we need to use this destroy function. 18:00.680 --> 18:02.760 And this destroy function in brackets. 18:02.760 --> 18:05.770 It's going to take the game object that we want to destroy. 18:05.930 --> 18:08.770 So we want to destroy itself or the enemy. 18:08.810 --> 18:10.330 One game object itself. 18:10.330 --> 18:12.970 So we're going to pass this start game object. 18:13.010 --> 18:16.490 It's basically referencing the enemy game object itself. 18:16.490 --> 18:19.050 And then we're going to close that off with a semicolon. 18:19.050 --> 18:21.930 But if we don't specify sorry. 18:21.970 --> 18:28.570 If we don't specify as a second argument the time then our enemy one just going to destroy right away 18:28.770 --> 18:35.730 and which we really don't want to, uh, be, uh, don't want which we really don't want. 18:35.730 --> 18:40.370 So that's why as a second argument, comma, we can specify the time. 18:40.370 --> 18:43.770 So after something like five second I just want to destroy. 18:43.770 --> 18:47.210 So that's why as a second argument I'm going to put five f. 18:47.250 --> 18:49.890 Or you can simply assume five seconds. 18:49.930 --> 18:53.210 And now I'm going to press down Ctrl S to save my script. 18:53.210 --> 18:54.850 And let's move over to unity. 18:55.050 --> 19:01.330 And if you don't assign the second argument then in your case the enemy one game object just gonna destroy 19:01.370 --> 19:04.230 itself immediately, which we don't want. 19:04.270 --> 19:07.790 So that's why as a second argument, we just pass the time. 19:07.950 --> 19:10.030 And now we're going to take a look on it. 19:10.150 --> 19:14.150 So let's click on this play button in the top in order to play our game. 19:14.150 --> 19:20.590 And let's attack on this enemy one game object three times in order to destroy this enemy completely 19:20.790 --> 19:22.230 and before it destroy. 19:22.270 --> 19:28.590 Firstly, it's gonna play that animation clip and after something like five seconds, it's gonna destroy 19:28.590 --> 19:29.310 itself. 19:29.310 --> 19:31.710 So let's get in attack range. 19:31.870 --> 19:37.790 And if we just, uh, three times, we can see by now it's played the death animation clip. 19:37.790 --> 19:40.110 And after five seconds you will see a. 19:40.150 --> 19:45.910 We can notice that after five seconds, that enemy one game object get destroy itself. 19:45.910 --> 19:51.230 And we cannot see in this in view as well as as well as in the hierarchy. 19:51.230 --> 19:58.630 So if I move over to my hierarchy, we cannot see our enemy one because it just destroy itself after 19:58.630 --> 20:01.190 five seconds that we specified the time. 20:01.190 --> 20:04.400 So I'm gonna get out of play mode, so I hope you get the idea. 20:04.440 --> 20:06.000 Firstly, we're just damaging. 20:06.200 --> 20:13.080 And once it's taking damage, we're checking if it's hit zero or something like less than one or equal 20:13.120 --> 20:16.240 or lesser than 1 or 0, something like that. 20:16.280 --> 20:21.360 If that is the case, then we're calling the die function and die function simply doing this thing. 20:21.400 --> 20:26.600 Firstly, it's printing out the message, then playing the animation clip and setting the gravity scale 20:26.640 --> 20:29.360 to zero so it's not gonna fall down at all. 20:29.480 --> 20:32.520 And after that we just disabling the box Collider 2D. 20:32.560 --> 20:39.720 So that's why it's not detecting any collision means even after if we disable that, then if we just 20:39.760 --> 20:46.360 attack on this enemy one GameObject, it's gonna and it's not gonna take any damage at all since we 20:46.360 --> 20:47.680 just disable that box. 20:47.680 --> 20:54.200 Collider 2D, which is responsible for detecting collision, and after five seconds we destroying the 20:54.200 --> 20:56.600 GameObject itself, as you can see. 20:56.680 --> 20:59.520 So I hope you get the idea that how you can do it. 20:59.880 --> 21:04.680 And I'm going to press down Ctrl s on my keyboard in order to save my project.
