WEBVTT 00:07.040 --> 00:08.160 Welcome back. 00:08.180 --> 00:14.300 Now we're just about ready to create blueprints based on aura, character and aura enemy. 00:14.660 --> 00:21.210 And we know that we can add things to aura character base, and these will both inherit those things. 00:21.230 --> 00:27.080 Now, I'd like all my characters to have a weapon, so I'm going to add a skeletal mesh component to 00:27.080 --> 00:33.830 the Aura character base, and I'd like to attach that to a socket on the skeleton, which means we'll 00:33.830 --> 00:38.570 need to make sure that our skeletal meshes have the socket that we specify. 00:38.750 --> 00:44.660 So in our protected section in Aura character base, I'm going to make a weapon, which is a skeletal 00:44.660 --> 00:53.480 mesh component pointer, and I'm going to use the T object pointer wrapper rather than a raw use skeletal 00:53.480 --> 00:54.930 mesh component pointer. 00:54.950 --> 01:00.950 Now, T object pointer is relatively new in unreal engine and a packaged build. 01:00.950 --> 01:07.380 It behaves the same as a raw pointer, but in editor it has some additional features, such as access 01:07.380 --> 01:10.530 tracking and optional lazy load behavior. 01:10.950 --> 01:16.950 Access tracking just means we can track how often a pointer is accessed or dereferenced. 01:16.950 --> 01:25.260 And lazy loading means that an asset can not be loaded until it's actually needed or used in the program. 01:25.260 --> 01:31.170 So the standard is moving more towards using object pointers for member variables. 01:31.170 --> 01:34.260 So we'll be following that standard in this project. 01:34.260 --> 01:39.450 And object pointer in this case will wrap a used skeletal mesh component. 01:39.480 --> 01:41.310 There's no need for the asterisk. 01:41.310 --> 01:47.550 We don't need to add that star, but we know that this is a pointer and we'll call this weapon. 01:48.060 --> 01:56.010 And I'm going to make this a uproperty as all of our member pointers should be, and we'll make this 01:56.010 --> 02:01.470 edit anywhere and I'll place it in the category of combat. 02:02.070 --> 02:09.270 So now we can actually create our skeletal mesh component in or a character base in the constructor. 02:09.270 --> 02:17.370 So we'll say weapon equals and we'll use create default subobject here specifying the use skeletal mesh 02:17.370 --> 02:21.870 component and in quotes we'll have simply weapon. 02:22.110 --> 02:28.380 Now, if you're asking why I haven't used the text macro here, that's because create default Subobject 02:28.410 --> 02:32.520 takes an F name and you don't need the text macro for F names. 02:32.520 --> 02:34.440 You need them for f strings. 02:34.470 --> 02:40.980 F string will take a string literal like this and perform an implicit conversion to a wide character 02:40.980 --> 02:44.880 string as that's what the f string type stores. 02:44.880 --> 02:49.290 But the F name can take a regular string literal just like this. 02:49.470 --> 02:57.600 Now I'd like to attach the weapon to a socket on the mesh, so I'm going to say weapon setup attachment. 02:57.750 --> 03:06.240 We'll attach it to the mesh so we'll access that through get mesh that's inherited from the A character 03:06.240 --> 03:07.380 class, of course. 03:07.380 --> 03:10.260 And we'll attach it to a socket. 03:10.260 --> 03:16.050 So I'm going to use an F name here and we're going to add a socket to the skeleton. 03:16.050 --> 03:18.690 We'll call this weapon hand socket. 03:18.690 --> 03:24.420 So we'll place a socket on one of the hands and our weapon will be attached to that. 03:24.420 --> 03:27.120 And the weapon should not have any collision. 03:27.120 --> 03:29.280 So I'm going to take the weapon and call. 03:29.280 --> 03:31.540 Set collision enabled using E! 03:31.560 --> 03:32.910 Collision enabled. 03:32.940 --> 03:34.320 No collision. 03:34.950 --> 03:37.620 So that should take care of collision. 03:37.620 --> 03:44.010 So now if we go and create some blueprints based on a character and or an enemy, they will have the 03:44.010 --> 03:49.200 weapon skeletal mesh component and we can set the skeletal mesh in the blueprint. 03:49.230 --> 03:55.320 Now, I'm not debugging any code, so I'm just going to hit run to compile and launch the editor. 03:55.930 --> 03:59.980 And with the editor open, I can now start making some blueprints. 04:00.010 --> 04:02.890 Now, I don't want things to be messy. 04:02.890 --> 04:05.740 I want a nice clean folder structure. 04:05.740 --> 04:10.330 So I'm going to have a new folder in content designated for all my blueprints. 04:10.330 --> 04:11.860 And I'll call it blueprints. 04:12.100 --> 04:16.650 And inside of blueprints I'll make a new folder called Character. 04:16.660 --> 04:22.660 And here in character, I'll have the Aura character as well as all my enemy characters. 04:22.660 --> 04:29.260 So here in character, I'll make an aura folder, and in Aura I'll make the aura blueprint. 04:29.260 --> 04:34.480 So I'm going to right click and make a new blueprint class and search for Aura character. 04:34.480 --> 04:36.430 I don't want Aura character base. 04:36.430 --> 04:38.350 I want my Aura character. 04:38.350 --> 04:47.650 So I'll select that and call this BP underscore aura character and we can go ahead and open it and set 04:47.650 --> 04:52.000 the mesh for the mesh variable as well as our weapon. 04:52.090 --> 04:53.620 So first the mesh. 04:53.620 --> 04:58.370 I'll take my skeletal mesh asset and right here we have Sxm aura. 04:58.400 --> 05:00.410 That's the aura skeletal mesh. 05:00.410 --> 05:01.670 I can move it down. 05:01.670 --> 05:06.020 I'd like snapping enabled for translation and rotation. 05:06.020 --> 05:11.300 I'll move it about 90 units down and exactly 90 units rotated. 05:11.300 --> 05:14.480 So it's forward and we can set our weapon. 05:14.480 --> 05:19.640 Before we do that, I'm going to add that socket that we called weapon hand socket. 05:19.640 --> 05:24.680 I'm going to actually copy that name and I'll take my aura. 05:24.710 --> 05:31.160 Let's browse to that and open it up and choose where we want the hand socket. 05:31.190 --> 05:35.150 Now the question is, do we want this on the left or right hands? 05:35.150 --> 05:39.860 And the animations that we have for aura, use the left hand. 05:39.890 --> 05:47.630 We can see that by going into the animations folder here in the same folder that Sxm aura exists in. 05:47.630 --> 05:50.990 And we can just take a look at, say, the idle animation. 05:50.990 --> 05:55.460 We can see that aura holds the weapon in the left hand. 05:55.670 --> 06:00.110 So back in Sxm aura, I'm going to add a socket to handle. 06:00.140 --> 06:02.330 That's the handle bone. 06:02.690 --> 06:04.340 We're going to add a socket. 06:04.340 --> 06:05.210 I'm going to click it. 06:05.210 --> 06:09.350 I'm going to click it again and paste in weapon hand socket. 06:09.860 --> 06:17.450 That way it has the correct name and we can position that socket by right clicking and adding a preview 06:17.450 --> 06:20.420 asset, searching for the staff. 06:20.480 --> 06:24.680 I'm going to get that skeletal mesh asset Sxm staff. 06:24.710 --> 06:26.840 The staff is the static mesh. 06:26.840 --> 06:33.140 I want the skeletal mesh and I'm going to go ahead and rotate it by about 90 degrees. 06:33.260 --> 06:39.800 And I want to preview this with an animation so I know that I'm positioning things correctly. 06:39.800 --> 06:45.380 So up here under animation, I can set preview controller to use specific animation. 06:45.380 --> 06:48.920 And for the animation I can choose any one of these. 06:48.950 --> 06:54.200 I'll choose Firebolt here and we have Aura casting a spell. 06:54.200 --> 07:02.480 I'm going to pause it somewhere in the middle and move this socket so that it looks correct. 07:02.510 --> 07:06.680 I'll move it forward a bit and just make sure that it looks good. 07:07.100 --> 07:08.690 I think that looks pretty nice. 07:08.690 --> 07:14.480 And I can switch to, say, the idle animation if I want to make sure it looks good there and perform 07:14.480 --> 07:16.100 any last minute tweaks. 07:16.280 --> 07:19.400 So I might actually angle it forward a bit. 07:19.400 --> 07:22.970 Let's take snapping and disable that for rotation. 07:23.920 --> 07:25.870 And just make sure it looks good. 07:27.700 --> 07:28.660 Okay, great. 07:28.660 --> 07:29.860 So we have the socket. 07:29.890 --> 07:36.490 We can go back to our character, select the weapon, and we can set that skeletal mesh. 07:36.880 --> 07:44.380 I'm going to search for staff and we have Sqms staff and we see that it's attached to the correct socket. 07:44.380 --> 07:48.820 And if you want to see that staff, just browse to it and inspect it. 07:48.850 --> 07:53.230 It's got some nice textures on it, really pretty staff. 07:53.230 --> 07:55.420 So that's going to be aughra's weapon. 07:55.840 --> 07:56.890 Okay, great. 07:56.890 --> 08:01.540 So we have the Aura character blueprint and that looks great. 08:01.570 --> 08:05.350 We can also make a blueprint for the enemy class. 08:05.350 --> 08:08.530 We'll go ahead and make one of those before we wrap it up. 08:08.560 --> 08:12.040 And that's actually going to be your quest. 08:12.040 --> 08:16.330 So for this quest, you're going to make a blueprint for the Goblin Enemy. 08:16.330 --> 08:25.720 Call it Goblin Spear now set the mesh and search for the goblin skeletal mesh in our assets folder and 08:25.720 --> 08:27.740 check out the skeleton on that goblin. 08:27.740 --> 08:34.790 Make sure you take care of the socket and then you can find the spear asset and set that for the weapon 08:34.790 --> 08:36.650 on the goblin blueprint. 08:36.680 --> 08:42.080 Go ahead and pause the video here and take care of making the Goblin Spear blueprint. 08:45.130 --> 08:47.330 Okay, so let's conquer this quest. 08:47.350 --> 08:54.940 I'm going to go into my character's folder and next to Aura, I'm going to make a new folder and I'll 08:54.940 --> 08:58.830 call this goblin underscore spear. 08:58.840 --> 09:05.080 And in Goblin Spear, I'll right click and make a new blueprint based on aura Enemy. 09:05.080 --> 09:13.270 So I'll choose that class and call this beep, underscore goblin, underscore spear, and I'm ready 09:13.270 --> 09:16.450 to open it up and set the mesh. 09:16.630 --> 09:20.710 So I'll select the mesh and search for Goblin. 09:20.710 --> 09:21.820 In fact, it's right here. 09:21.820 --> 09:23.470 I can go ahead and select it. 09:23.470 --> 09:27.760 I can move it down, I can rotate it by 90 degrees. 09:27.760 --> 09:29.680 I don't have snapping on it looks like. 09:29.680 --> 09:34.390 So I'm going to undo that, enable snapping and rotate by 90 there. 09:34.510 --> 09:36.610 Now this is a little guy. 09:36.610 --> 09:39.820 We can make that capsule a bit smaller. 09:39.820 --> 09:42.940 So we'll go ahead and just bring it in a bit. 09:42.940 --> 09:45.650 Just a cute little goblin enemy. 09:45.860 --> 09:53.090 It's going to be really sad to kill these guys, but that's the price you have to pay to be a hero, 09:53.090 --> 09:53.690 right? 09:53.690 --> 09:56.150 So I have my goblin. 09:56.150 --> 09:58.130 It needs a weapon as well. 09:58.130 --> 10:00.830 So let's take care of the socket situation. 10:00.830 --> 10:05.900 I'm going to browse to goblin, open it up and look at that. 10:05.900 --> 10:09.620 We do have a socket on the left hand bone. 10:09.620 --> 10:16.760 Now I'd like to see what it looks like with a spear so I could right click, add a preview asset and 10:16.760 --> 10:19.820 search for spear and choose the spear. 10:19.850 --> 10:21.680 That's the skeletal mesh component. 10:21.680 --> 10:29.030 Looks like it's in the correct location and we can set the preview controller to use specific animation 10:29.030 --> 10:32.630 and see if we have any spear attack animations. 10:32.630 --> 10:36.890 Looks like we have attack spear and it looks pretty good. 10:36.890 --> 10:40.400 I don't think we need to really do any adjustments on that. 10:40.430 --> 10:46.700 Thanks to the creator of these assets positioning that socket correctly for us. 10:46.700 --> 10:47.900 All right. 10:47.930 --> 10:51.850 Now we do need to make sure that that socket name is correct. 10:51.860 --> 10:53.630 Hopefully this didn't trip you up. 10:53.630 --> 10:56.300 It needs to be weapon hand socket. 10:56.300 --> 11:00.290 So we are going to need to rename this socket. 11:01.800 --> 11:06.690 I'm going to paste in weapon hand socket and save that. 11:06.690 --> 11:10.880 And now in Goblin Spear, I can select weapon. 11:10.890 --> 11:16.710 I can search for spear and set that weapon to the spear and it looks good. 11:16.890 --> 11:23.340 So now we have a weapon based on aura enemy called Goblin Spear. 11:23.340 --> 11:28.320 And if you'd like to see what they look like next to each other, if you're curious, you could drag. 11:28.320 --> 11:32.190 In an instance of these blueprints. 11:32.190 --> 11:33.840 I can browse to Aura. 11:35.780 --> 11:40.310 Drag aura in there, and I can browse to the goblin. 11:41.400 --> 11:43.170 And drag in the goblin. 11:43.170 --> 11:48.120 And as you can see, the goblin is a good deal shorter than aura. 11:48.360 --> 11:51.270 So that gives you an idea of what they look like. 11:51.300 --> 11:56.400 I'll go ahead and delete those, however, I don't need them in the world just yet. 11:56.400 --> 11:59.790 And now we have some characters to work with. 11:59.790 --> 12:00.660 Excellent. 12:00.690 --> 12:04.980 I'll go ahead and save all before I close out of the editor. 12:05.370 --> 12:11.550 And we're now ready to create some animation blueprints for our characters and we'll do those next. 12:11.790 --> 12:12.810 I'll see you soon.
