WEBVTT 00:00.040 --> 00:03.720 Let's keep health amount to this enemy pawn game object. 00:03.720 --> 00:09.280 So let's select the enemy one game object in the hierarchy, and let's open up the enemy one script 00:09.280 --> 00:10.920 by double clicking on it. 00:10.920 --> 00:13.040 And let's go to top of our class. 00:13.040 --> 00:16.480 And let's declare a variable for our Maxell. 00:16.640 --> 00:20.560 So we will scroll up and let's make it over here. 00:21.120 --> 00:22.920 Uh, let's make it here. 00:22.920 --> 00:29.200 So just wait and let's give it a title before we create the variable or declare the variable. 00:29.200 --> 00:31.560 So let's give a header header. 00:31.600 --> 00:33.800 Sorry we're going to give a header. 00:33.800 --> 00:36.760 So let's make this square brackets header. 00:36.920 --> 00:40.320 And we're going to say something like health uh health. 00:40.360 --> 00:42.880 And let's create a serialized field. 00:43.440 --> 00:46.960 So let's create a serialized field private. 00:47.320 --> 00:49.120 And this will be int. 00:49.120 --> 00:52.200 And we can call this one something like Max health. 00:52.520 --> 00:56.600 And by default I'm going to give something around three unit of health. 00:57.040 --> 01:01.180 And now we're gonna make a function in order to take damage. 01:01.180 --> 01:04.260 And let's make it in the bottom somewhere over here. 01:04.460 --> 01:09.100 And we're going to make this function public, since we're going to call this function from another 01:09.100 --> 01:11.020 class or another script. 01:11.020 --> 01:15.340 So that's why for so let's mark this function as public. 01:15.540 --> 01:17.700 And for function we're going to type void. 01:17.740 --> 01:19.220 And we have to name the function. 01:19.220 --> 01:21.940 So let's call it something like take damage. 01:22.420 --> 01:23.660 Let's call it take damage. 01:23.660 --> 01:26.540 Let's make first bracket and some curly brackets. 01:26.700 --> 01:28.260 And this take damage function. 01:28.260 --> 01:30.220 Just going to take an argument. 01:30.220 --> 01:34.060 And that will be in type like whole number 01234. 01:34.060 --> 01:38.340 And we can call this one amount a amount something like that. 01:38.380 --> 01:41.140 Let's call it instead damage amount. 01:41.300 --> 01:44.140 So let's call it damage amount. 01:44.540 --> 01:50.020 And later on we're going to replace this damage amount with real numbers like 1234. 01:50.460 --> 01:52.780 But I'm going to test with one. 01:52.780 --> 01:55.940 So now what we basically have to do inside that function. 01:56.100 --> 02:00.450 We basically need to subtract from this max health by that damaged amount. 02:00.690 --> 02:02.090 So let's do that. 02:02.090 --> 02:04.130 So we will subtract from our max. 02:04.370 --> 02:08.050 So max minus equivalent in order to subtract that. 02:08.050 --> 02:11.410 And we just want to subtract with our damage amount. 02:11.410 --> 02:13.410 And let's close that up with semicolon. 02:13.970 --> 02:15.690 So now this finds. 02:15.690 --> 02:19.370 So let's suppose we call this takedamage function for the first time. 02:19.370 --> 02:21.970 So the max health by default we have given three. 02:22.010 --> 02:24.850 And let's assume this damage amount we pass one. 02:24.850 --> 02:26.410 So this one is one. 02:26.410 --> 02:28.650 So three minus one is just going to be two. 02:28.850 --> 02:33.570 And if we call this damage function for the second time max health is now two. 02:33.690 --> 02:35.650 So two minus one is going to be one. 02:35.650 --> 02:40.330 And if we call this takedamage function for the third time max health is now one. 02:40.330 --> 02:42.610 So one minus one is going to be zero. 02:42.610 --> 02:49.730 So our max health just going to hit zero whenever uh at some point it's hit it just going to hit zero. 02:50.010 --> 02:53.610 So in that moment we need to destroy our player game object. 02:53.610 --> 02:58.550 And let's, uh, let's suppose, uh, our max health is already zero. 02:58.550 --> 03:01.430 And let's suppose we call this function. 03:01.430 --> 03:03.150 So the max cell is zero. 03:03.150 --> 03:05.470 So zero minus one gonna be minus one. 03:05.470 --> 03:07.910 So it will move over to negative value. 03:07.910 --> 03:12.750 So before we subtract we want to check if the max cell is already zero. 03:12.790 --> 03:14.910 Then we need to stop subtracting. 03:14.910 --> 03:21.630 So we will check if if let's make first bracket and some curly brackets and what we want to check over 03:21.630 --> 03:21.870 here. 03:21.910 --> 03:28.310 We basically want to check if our max cell, if it's lesser than or equal to zero, means we need to 03:28.350 --> 03:28.750 stop. 03:28.750 --> 03:33.710 Subtracting means we need to stop executing this line of code which is subtracting. 03:33.710 --> 03:35.950 So that's why we're going to type this return. 03:35.950 --> 03:42.030 And after return, whatever we're going to do it's not going to be executed at all means our Maxwell 03:42.030 --> 03:43.630 just going to start at zero. 03:43.630 --> 03:50.430 As you can see, whenever our max cell hits zero, as you can see right over here, we type in return 03:50.430 --> 03:56.470 and after return, whatever we're going to do, it's not going to execute at all means our Maxwell just 03:56.470 --> 03:58.140 going to gonna start at zero. 03:58.900 --> 04:03.820 And we also need to create a die function in order to destroy our player. 04:03.980 --> 04:05.900 So let's make it over here. 04:05.900 --> 04:10.260 And this function doesn't need to be public or private or public. 04:10.260 --> 04:12.380 So we can make it private instead. 04:12.380 --> 04:19.940 So if we type void and if we don't assign a right in front of this, something like private or public, 04:19.980 --> 04:25.860 then this function automatically get marks as a mark marked as a private function. 04:26.300 --> 04:29.340 For function we type void and we have to name the function. 04:29.340 --> 04:30.540 So I'm going to call it die. 04:30.740 --> 04:33.260 Let's make first bracket and some curly brackets. 04:33.260 --> 04:39.980 So what we want to do inside this function we basically want to destroy our enemy one game object. 04:39.980 --> 04:45.940 But before we destroy let's print out the message that we want to see something like this enemy one 04:45.940 --> 04:47.140 game object dies. 04:47.140 --> 04:50.740 So for printing out message we're going to type this debug dot log. 04:51.060 --> 04:59.680 And we can say something like this dot game object dot name, dot name, and top of that I'm going to 04:59.680 --> 05:01.080 add a custom message. 05:01.080 --> 05:02.800 So use this plus icon. 05:02.800 --> 05:03.160 Sorry. 05:03.200 --> 05:09.200 Use this plus and then quotation and you can put whatever you want in between these quotation. 05:09.240 --> 05:13.640 Say something like diet and let's close that up with semicolon. 05:13.760 --> 05:17.640 So this dot game object basically means it just referencing itself. 05:17.640 --> 05:22.400 So the enemy one script we can see it's attached to this anime one game object. 05:22.400 --> 05:28.040 And we can see the name of this anime one in Inspector we can see is anime one. 05:28.040 --> 05:29.840 So the message should be pop up. 05:29.840 --> 05:34.560 So this right over here is just going to be anime one, basically the name of the game object. 05:34.560 --> 05:37.880 And on top of that we just added this message which says type. 05:37.920 --> 05:44.280 So anime one type message should be pop up in our console tab whenever we're going to call this function. 05:44.280 --> 05:51.680 So we can call this function once our Maxell loses zero right over here, we can call it uh, we can 05:51.680 --> 05:55.510 call it or we can call it in the update function as well. 05:55.510 --> 05:58.670 So let's call it inside update function instead of doing. 05:58.710 --> 05:59.230 There. 05:59.230 --> 06:01.630 So let's move over to this update function. 06:01.630 --> 06:03.670 So we do know that update function runs. 06:03.710 --> 06:05.070 Every single frame. 06:05.070 --> 06:08.550 So every single frame we're just going to keep track of our max cell. 06:08.710 --> 06:09.790 So we will check. 06:09.790 --> 06:13.070 If so let's make first bracket and some curly brackets. 06:13.070 --> 06:14.270 So what we want to check. 06:14.310 --> 06:18.630 Over here we basically want to check the max health of that animation. 06:18.630 --> 06:21.270 So if our max health max health. 06:21.310 --> 06:26.150 If it's less than or equal to zero means we need to destroy our plate. 06:26.270 --> 06:26.630 Sorry. 06:26.670 --> 06:28.550 We need to destroy our enemy. 06:29.150 --> 06:29.910 Itself. 06:29.910 --> 06:32.190 So we can simply call the die function. 06:32.190 --> 06:33.990 And what die function just going to do? 06:34.030 --> 06:34.390 It's going. 06:34.430 --> 06:40.470 To print out the message in the console says this dot game Objectname basically the name of the game 06:40.510 --> 06:42.510 object, which is anime one. 06:42.510 --> 06:45.350 And top of that we added this message says type. 06:45.390 --> 06:46.630 So enemy one died. 06:46.670 --> 06:49.550 Message should be pop up in our console tab. 06:49.550 --> 06:53.390 So let's call the function here once our max health reaches zero. 06:53.390 --> 06:54.970 So we're going to call the function ty. 06:55.170 --> 06:58.530 Let's make first bracket and then close that off with semicolon. 06:58.530 --> 07:01.290 And we're going to press down Ctrl s to save our script. 07:01.290 --> 07:03.170 And now let's move over to unity. 07:03.690 --> 07:12.290 So we should be able to notice that message whenever our Maxwell just reaches zero of this enemy one 07:12.290 --> 07:13.090 GameObject. 07:13.410 --> 07:19.050 But the thing is that we're not going to able to notice why we just made that Takedamage function, 07:19.050 --> 07:21.330 and we never calling it anywhere. 07:21.330 --> 07:22.930 So we also need to call it. 07:22.930 --> 07:29.890 But when we need to call it once, these are our player GameObject attack on this enemy one game object. 07:29.890 --> 07:34.090 Once our player GameObject attack on this enemy one GameObject. 07:34.090 --> 07:42.490 In that moment, we need to call that function from that enemy script or from that enemy one C class. 07:42.490 --> 07:44.610 So just wait a moment and you will see. 07:45.330 --> 07:55.030 And a nice title just gonna pop up underneath our enemy one script as says Max health or health as we 07:55.030 --> 07:56.350 have given the title. 07:56.630 --> 08:04.510 And also, I really apologize for taking a little bit longer time than as usual, you know that my system 08:04.510 --> 08:09.670 is a little bit slow, so that's why it's taking pretty much long time. 08:10.270 --> 08:18.230 Uh, so in this time lapse, I can just I can just explain what, uh, basically going on. 08:18.590 --> 08:25.510 And now enemy one script just getting compile, and once it's compiled, we can see underneath our enemy 08:25.550 --> 08:31.150 one script in Inspector Health pop up and the max health by default we have given five. 08:31.150 --> 08:36.990 So if I move over to my console tab and then click on this play button and try to damage this enemy, 08:36.990 --> 08:44.710 one game object, uh, this enemy, one game object, then this enemy one should lose, uh, some unit 08:44.750 --> 08:47.270 of health from this max health. 08:47.430 --> 08:49.550 But the problem is that it own. 08:49.590 --> 08:50.110 Why? 08:50.150 --> 08:53.260 Because we also need to call the Takedamage function. 08:53.260 --> 08:54.140 Let me show you. 08:55.060 --> 08:56.460 So just wait a moment. 08:57.620 --> 09:03.020 So now if we just get in attack range and try to attack on this enemy one. 09:03.420 --> 09:10.940 Uh, that, as you can see, uh, Max health is not going to four, three, two, one as even though 09:10.940 --> 09:14.100 we attacking, uh, even though we attacking. 09:14.100 --> 09:19.300 So what basically going on if I get out of play mode and then move over to my enemy. 09:19.340 --> 09:24.700 One script that we just created this function and we never calling it anywhere. 09:24.700 --> 09:31.340 So that's why this line of code not getting execute basically we not subtracting at all our damage amount. 09:31.340 --> 09:37.980 So when we need to do it, once our uh player GameObject attack on this enemy one game object. 09:37.980 --> 09:44.140 So if I move over to my console tab, as you can see, a message just getting pop up says circle colliding 09:44.140 --> 09:44.980 with enemy. 09:45.020 --> 09:50.500 Basically, if I select my player GameObject in the hierarchy, move over to animation tab and then 09:50.500 --> 09:52.440 choose this attack one or attack two. 09:52.480 --> 09:57.080 As you can see right over here, we created that attack function. 09:57.080 --> 10:00.600 So over here we can call the function which is damage amount. 10:00.600 --> 10:07.080 So basically what we need to do we need to open up our attack function inside this player game object 10:07.080 --> 10:08.840 that we created earlier. 10:09.120 --> 10:12.320 So we will select our player game object in the hierarchy. 10:12.360 --> 10:16.560 Then go over to Inspector and open up the player script by double clicking on it. 10:16.560 --> 10:18.800 And let's move over to that function. 10:18.800 --> 10:19.640 In which function? 10:19.640 --> 10:24.400 We just, uh, we basically, uh, just, uh, printing out the message. 10:24.400 --> 10:29.240 As you can see, if call info is true basically means the circle is colliding. 10:29.240 --> 10:32.960 Basically this circle colliding with this enemy one game object. 10:33.000 --> 10:36.920 Once our this player just playing the attack animation clip. 10:36.920 --> 10:43.240 So instead of printing out message like this, as you can see, uh, our circle collided with and the 10:43.240 --> 10:44.360 name of the game object. 10:44.360 --> 10:51.710 Instead of doing that, we can simply call the Takedamage function from that enemy class as we created 10:51.750 --> 10:54.710 before, so we can simply call it over here. 10:54.710 --> 10:57.230 So instead of printing out message, we're going to call. 10:57.230 --> 10:59.550 But before we call we just want to check. 10:59.710 --> 11:02.550 So what we want to check is the circle. 11:02.550 --> 11:08.990 If the circle is really collided with this enemy one game object, then only that moment we want to 11:09.230 --> 11:10.590 call the Takedamage function. 11:10.590 --> 11:15.150 Basically this enemy one just gonna take damage, else we're not gonna do it. 11:15.150 --> 11:18.910 So before we damage it, we need to check what we colliding with. 11:19.070 --> 11:24.190 So that's why we're going to use this call info in order to extract information. 11:24.190 --> 11:25.910 So we will use this if condition. 11:25.910 --> 11:28.710 Let's make first bracket and some curly brackets. 11:28.710 --> 11:30.390 So what we want to check over here. 11:30.390 --> 11:36.590 We basically want to check if call info dot game GameObject dot get component. 11:36.590 --> 11:39.390 And we will check for our enemy one script. 11:39.390 --> 11:44.030 So we will type enemy one if it's and then make this first bracket. 11:44.030 --> 11:48.390 And we will check if it's not equal to null basically means what. 11:48.430 --> 11:55.210 Basically this means call con, call info.com object basically means the game object the circle collided 11:55.210 --> 11:55.730 with. 11:55.730 --> 11:59.130 So the circle is just going to collide with this enemy one game object. 11:59.130 --> 12:02.050 Then what we're doing we just going over to that. 12:02.090 --> 12:04.570 Then we're just taking our enemy one script. 12:04.570 --> 12:08.210 As you can see Dot get component and enemy one. 12:08.210 --> 12:11.530 And we're checking if that script is not equal to null. 12:11.690 --> 12:17.770 So firstly we're just going over to this enemy one game object and accessing this enemy one script. 12:17.770 --> 12:23.690 And we're checking if this enemy one script is not equal to null basically means that this enemy one 12:23.770 --> 12:27.170 script is attached to this enemy, one game object. 12:27.170 --> 12:32.490 And indeed we can see enemy one script is attached to this enemy, one game object. 12:32.490 --> 12:38.690 So if that is the case and not equal to null, basically means that enemy one is script is attached 12:38.690 --> 12:40.490 to that enemy one game object. 12:40.530 --> 12:47.090 Now we can what we can do, we can simply call our Takedamage function from that enemy one script. 12:47.210 --> 12:50.590 But before we do, let's print out a message now. 12:51.790 --> 12:54.550 Say something like a text message. 12:54.550 --> 12:58.590 So we're going to type this debug dot log in order to print out message. 12:58.590 --> 13:02.630 And we can say any one taking damage something like that. 13:02.630 --> 13:06.430 And upon taking damage damage. 13:06.430 --> 13:08.350 And let's close that up with semicolon. 13:08.350 --> 13:11.390 And we're going to press down Ctrl S to save our script. 13:11.390 --> 13:13.270 And now let's move over to unity. 13:13.630 --> 13:17.830 And the circle really gonna collide with this enemy one. 13:17.830 --> 13:23.790 And we're checking if the enemy one script is not equal to null basically means that enemy one script 13:23.830 --> 13:26.310 attached to this enemy one game object. 13:26.310 --> 13:31.230 And indeed we can see enemy one script is attached to this enemy, one game object. 13:31.230 --> 13:37.670 Then what we're doing, we printing out a message in the console says enemy one taking damage. 13:37.950 --> 13:39.430 Enemy one taking damage. 13:39.430 --> 13:45.710 So this message is just going to pop up whenever we're gonna attack on this enemy one game object once 13:45.710 --> 13:50.540 our player just gonna attack on on to this enemy. 13:50.580 --> 13:51.460 One game object. 13:51.460 --> 13:53.220 So I'm going to select my console tab. 13:53.220 --> 13:57.380 And let's click on this play button in the top in order to play our game. 13:57.380 --> 13:59.140 And let's have a look on this. 13:59.140 --> 14:03.820 And we created the Takedamage function inside this enemy one script. 14:03.820 --> 14:05.820 So we need to call the function. 14:05.820 --> 14:10.660 So if we call that function then this enemy one just going to take damage. 14:10.660 --> 14:17.460 So if I get in attack range and then damage it basically uh attack on it, we can see a message. 14:17.460 --> 14:23.300 So if I pause my game in the top by clicking on this pause button in the top, you can see in the middle 14:23.340 --> 14:23.780 top. 14:24.020 --> 14:30.460 And if we move over to our console tab, we can see a message just getting pop up says enemy one taking 14:30.500 --> 14:31.140 damage. 14:31.140 --> 14:37.500 So instead of printing out message what we really want to do, we basically want to, uh, basically 14:37.500 --> 14:39.620 want to damage this enemy one. 14:39.620 --> 14:45.020 So let's get out of play mode and let's double click on this message in order to move over to that line 14:45.060 --> 14:45.700 of code. 14:45.700 --> 14:50.800 So instead of printing out message, we're going to call the Takedamage function from that enemy one 14:50.800 --> 14:51.200 script. 14:51.320 --> 14:56.080 So if I move over to enemy one script, as you can see we created the function. 14:56.080 --> 14:57.640 So we're going to call this function. 14:57.640 --> 15:01.040 So let's call it to call it what we're gonna do. 15:01.080 --> 15:08.680 We're going to use this call info parameter in order to access anything that we just are looking for. 15:08.680 --> 15:12.920 So we're going to access Call info dot GameObject and call info. 15:12.920 --> 15:19.200 Dot GameObject basically means the GameObject the circle collided with and we want to access the enemy 15:19.240 --> 15:19.840 one script. 15:19.840 --> 15:20.960 So let's get that. 15:20.960 --> 15:24.040 And to get that we're going to use this dot get component. 15:24.040 --> 15:28.480 And the component we're looking for is enemy one or enemy one script. 15:28.480 --> 15:30.600 You can simply say enemy one. 15:30.600 --> 15:32.160 Then make this first bracket. 15:32.160 --> 15:35.080 And in there we created that Takedamage function. 15:35.080 --> 15:38.720 So let's access that or let's simply call it here. 15:38.720 --> 15:43.280 So we're going to type this dot and we're going to call the Takedamage function. 15:43.280 --> 15:46.000 And then make this first bracket as a argument. 15:46.110 --> 15:51.630 It's going to take the damage amount as we pass the argument, as you saw earlier. 15:52.150 --> 15:59.870 So if you just put a three, then our enemy one just gonna die right away since we already given three 15:59.870 --> 16:00.990 unit of health. 16:01.030 --> 16:03.550 But I want to subtract by one unit. 16:03.550 --> 16:06.670 So that's why as a damage amount I'm going to pass one. 16:06.790 --> 16:08.950 And let's close that up with semicolon. 16:08.950 --> 16:15.470 So that enemy one game object just gonna lose one unit of health as soon as we're gonna attack on it. 16:15.670 --> 16:20.470 And now we're gonna press down Ctrl s to save our script and then move over to unity. 16:20.550 --> 16:25.750 So as soon as we're gonna damage this enemy one, we will able to notice this. 16:25.750 --> 16:27.950 Maxhealth just gonna move over to. 16:27.990 --> 16:28.470 Sorry. 16:29.030 --> 16:31.030 Uh, we have given three. 16:32.990 --> 16:33.790 It shouldn't be. 16:33.830 --> 16:35.110 It should be five. 16:35.230 --> 16:36.110 Uh, I don't know. 16:36.310 --> 16:40.990 We have given, uh uh, three, but I don't know. 16:42.150 --> 16:49.090 I really apologize that we have given five Instead of giving five, I'm gonna pass three as a maxhealth. 16:49.450 --> 16:52.650 Uh, so I'm gonna pass three right over here. 16:52.690 --> 16:53.730 Now, this is fine. 16:54.290 --> 16:56.530 So this seems pretty much cool by now. 16:56.530 --> 17:02.530 So if we attack on this enemy one game object three times, then it's gonna lose all of his health. 17:02.530 --> 17:08.370 And once it's lose all of his health, then what we're doing, if we move over to enemy one script we 17:08.730 --> 17:10.450 call calling the die function. 17:10.450 --> 17:16.930 As you can see, once our maxhealth is less than or equal to zero, then we calling the die function 17:16.930 --> 17:18.170 and die function. 17:18.170 --> 17:22.730 Simply printing out this message in the console says enemy one died. 17:22.770 --> 17:23.810 As you can see. 17:23.970 --> 17:27.490 So now let's move over to unity and let's select the console tab. 17:27.650 --> 17:31.970 And let's click on this play button in the top in order to play our game. 17:31.970 --> 17:35.330 And let's attack on this enemy one game object. 17:35.330 --> 17:41.530 So, uh, once we are gonna attack three times, it's gonna lose all of his health, then die function. 17:41.530 --> 17:43.770 Just gonna call out and die function. 17:43.770 --> 17:46.840 Just going to print out the message says enemy one died. 17:46.880 --> 17:48.320 So let's attack on it. 17:48.320 --> 17:52.040 So if I attack so maxhealth we can see it's now became two. 17:52.080 --> 17:55.800 If we attack second time, we can see it's now one. 17:55.800 --> 17:58.600 And if we attack third time, then it's going to be zero. 17:58.720 --> 18:00.920 And we can see max health is zero. 18:00.920 --> 18:06.480 And as soon as it reaches zero, if we move over to console tab, enemy one died. 18:06.520 --> 18:09.240 Message just getting pop up every single time. 18:09.240 --> 18:09.600 Why? 18:09.800 --> 18:12.800 Because we're calling inside this update function. 18:12.800 --> 18:15.920 And we do know that update function runs every single frame. 18:15.920 --> 18:17.240 So every single frame it. 18:17.240 --> 18:21.000 Just checking the max if is then just calling that I function. 18:21.000 --> 18:26.680 So that's why every single frame the die function is calling out, and the die function simply printing 18:26.680 --> 18:29.440 out this passage over again and again. 18:29.440 --> 18:32.920 So we need to show up a die, something like that. 18:32.960 --> 18:34.480 We need to show that up. 18:34.800 --> 18:39.560 So death animation we need to play up this enemy one game object. 18:39.560 --> 18:41.200 So I'm going to get out of play mode. 18:41.200 --> 18:44.120 So I hope you get the idea that how you can do it.
