WEBVTT 00:00.050 --> 00:00.440 Hello guys. 00:00.440 --> 00:01.310 Welcome to the video. 00:01.310 --> 00:05.150 So this is going to be clean up and wrap up for this section. 00:05.150 --> 00:06.770 We did a lot of work. 00:06.770 --> 00:08.390 I think we did a pretty good job. 00:08.390 --> 00:11.450 We did set up a bunch of mechanics that we can use on the levels. 00:11.450 --> 00:16.580 And there are some things that I skipped, but it's only because I think we did enough with the traps 00:16.580 --> 00:22.400 and we need to move on to the enemies UI sounds, because if you do the same thing for a while, it 00:22.400 --> 00:24.680 can get tiresome and pretty boring, I would say. 00:24.680 --> 00:27.650 And I want to, you know, keep going with the development. 00:27.650 --> 00:32.420 Uh, so we did arrow, we did volume platform fire. 00:32.810 --> 00:34.670 This is just a platform. 00:34.670 --> 00:36.260 Nothing special. 00:36.500 --> 00:37.640 This one we didn't do. 00:37.640 --> 00:43.040 It seems interesting to me, but also I'm not sure if we really need it because I don't like the idea 00:43.040 --> 00:43.550 of itself. 00:43.550 --> 00:47.720 It's basically like an enemy, but we're going to have a bunch of enemies, so I don't know, why would 00:47.720 --> 00:48.650 we need this one? 00:49.220 --> 00:49.820 And we did. 00:49.820 --> 00:54.260 So spiked ball spikes, trampoline, so many cool things. 00:54.260 --> 00:55.340 I like it a lot. 00:55.340 --> 00:56.060 Yeah. 00:56.570 --> 01:03.140 Now what I'm going to do here is something nice before we finish this section on a trap. 01:03.140 --> 01:03.710 So. 01:04.530 --> 01:06.750 We dig in waypoints to move the object. 01:06.750 --> 01:13.020 And I'm afraid it may happen that you make another waypoint and you forget to add it to the script. 01:13.020 --> 01:14.970 So this is what I want to do. 01:15.450 --> 01:19.050 Uh, first let's go to traps and make. 01:20.070 --> 01:22.350 C sharp script trap. 01:23.340 --> 01:29.220 So we point and we're going to select waypoints. 01:30.380 --> 01:31.730 That we have. 01:31.730 --> 01:32.750 Let me delete the extra. 01:32.750 --> 01:36.800 Let's select this waypoints and put it on the object. 01:36.800 --> 01:41.360 So now these objects have a component of a Trapsoul waypoint. 01:41.950 --> 01:46.030 And I think I just will clean it up like so. 01:46.030 --> 01:47.650 I don't need anything here. 01:48.040 --> 01:50.410 Just that now I'm going to save it. 01:50.410 --> 01:52.060 I'm going to go to Trapsoul. 01:52.600 --> 01:55.360 And when we updating waypoints info. 01:55.360 --> 01:57.610 What I want to do here is to make a list. 01:57.640 --> 02:03.610 List is basically like an array, but the difference is that list can be changed dynamically. 02:03.610 --> 02:08.920 You can remove or add elements in the script in the start or during the game itself. 02:08.920 --> 02:13.930 And I want to use list of waypoints just like that. 02:13.930 --> 02:17.530 And it's going to be equals to new list of waypoints. 02:17.530 --> 02:27.520 And in the parentheses we're going to type get components in children with a plural of list trap waypoint 02:27.850 --> 02:29.440 of trap waypoint. 02:32.060 --> 02:32.900 Nice. 02:32.900 --> 02:33.980 What is it? 02:36.820 --> 02:40.480 All we need to give it a name waypoint list. 02:40.480 --> 02:41.680 So what it does. 02:41.680 --> 02:43.600 I know it's super confusing here. 02:43.600 --> 02:52.450 It makes a new list as a local variable, and it makes it equals to the new list, which is filled with 02:52.450 --> 02:56.590 the objects that we get as a components in children. 02:56.590 --> 02:59.320 Basically this one it does. 02:59.320 --> 03:06.820 And just to explain why we need it, we can go and just do debug log waypoint list dot count. 03:06.820 --> 03:08.530 Let's see how many we collect. 03:10.360 --> 03:13.690 And over here I'm going to duplicate one. 03:15.620 --> 03:17.540 Like so and go to play mode. 03:20.050 --> 03:22.150 And we can see we have message four. 03:22.150 --> 03:24.340 We've got four waypoints. 03:26.710 --> 03:31.000 This will help us to check how many waypoints we have under the trap. 03:31.000 --> 03:37.030 So then we can go ahead over here and compare the lengths. 03:39.430 --> 03:41.170 Of the waypoints and do this. 03:41.170 --> 03:50.740 If waypoint list dot count is not equals to waypoint dot length means we forgot to assign some of the 03:50.740 --> 03:59.560 waypoints into the list in the inspector over here, and if that's the case, then we can do waypoint. 04:00.910 --> 04:06.430 Equals to new transform array with a waypoint list count. 04:06.430 --> 04:14.380 And then we will do for loop with a waypoint list count and we will do waypoint I is equals to waypoint 04:14.380 --> 04:18.340 list I dot transform just like that. 04:18.340 --> 04:18.730 Yeah. 04:18.730 --> 04:19.660 What are we doing here? 04:19.660 --> 04:24.790 Maybe it's a bit confusing because I had to think while I'm typing we make it an empty list. 04:25.060 --> 04:32.290 A new list in the method as a local variable, and we're collecting all of the children of a these gameobjects 04:32.290 --> 04:33.730 that having a trap. 04:33.730 --> 04:35.860 So waypoint component. 04:35.860 --> 04:38.650 So now we have a list of waypoint components. 04:38.650 --> 04:44.110 Then we check if count of this list is not equals to the waypoint length that we have in the inspector 04:44.110 --> 04:49.570 over here means we have more children that we assigned in the waypoint list over here. 04:50.080 --> 04:57.250 And if that's the case then we take waypoint array and making it equals to new empty array with the 04:57.250 --> 04:59.320 length of a waypoint list count. 04:59.320 --> 05:05.170 Then we take in a for loop that runs the same amount of time as elements we have in our waypoint list, 05:05.170 --> 05:08.740 and making each I equals to the element from the list. 05:08.980 --> 05:15.820 And now because of that, we will collect all of the objects and put them into the array just like that. 05:15.820 --> 05:18.550 This basically will automate the process. 05:18.550 --> 05:21.010 And now we can go back to unity. 05:21.490 --> 05:24.610 And let's say you want to extend the travel of the. 05:24.610 --> 05:27.940 So just by adding more waypoints like. 05:28.990 --> 05:31.180 That, for example. 05:31.180 --> 05:31.870 Why not? 05:31.870 --> 05:33.070 Yeah, seven of them. 05:33.070 --> 05:37.840 And it would be a headache to assign them into array again, especially if you have a bunch of things 05:37.840 --> 05:39.430 to set up on different levels. 05:39.430 --> 05:42.010 So now we can just go to play mode. 05:43.780 --> 05:50.710 And it will be automatically collected into the waypoint array and then automatically given to the Vector3 05:50.890 --> 05:52.210 array with the positions. 05:52.210 --> 05:55.960 And now Trapsaw is travelling just like that. 05:59.790 --> 06:00.720 You see the point? 06:00.780 --> 06:01.500 Yeah. 06:01.530 --> 06:02.100 Nice. 06:02.100 --> 06:03.870 If you decide to delete some. 06:05.340 --> 06:06.090 I'd say delete some. 06:06.090 --> 06:07.020 Now you have less. 06:07.020 --> 06:11.460 You don't have to adjust array again because you can just go to play mode. 06:13.310 --> 06:14.360 And. 06:14.970 --> 06:17.070 It will take all of the elements you have. 06:17.100 --> 06:22.860 I'm still going to keep this variable open and visible so we can see how it's working. 06:22.950 --> 06:25.170 But other than that, we're good. 06:25.200 --> 06:27.180 This is just brilliant, I think. 06:27.600 --> 06:28.530 All right. 06:28.530 --> 06:29.430 This is good. 06:29.430 --> 06:31.980 Now let me apply override. 06:32.770 --> 06:33.610 And. 06:34.890 --> 06:38.280 Regarding other scripts, I was pretty careful, so I think it's fine. 06:38.280 --> 06:42.420 I'm just going to quickly check everything and then we're going to wrap this up and that's going to 06:42.420 --> 06:43.740 be good for this section. 06:44.250 --> 06:45.870 Yeah I think it's all super good. 06:45.870 --> 06:47.700 Thank you so much for paying attention guys. 06:47.700 --> 06:49.080 Let's go to the next section. 06:49.080 --> 06:50.700 We're going to work with enemies.
