1 00:00:04,320 --> 00:00:05,290 ‫Hello and welcome. 2 00:00:05,290 --> 00:00:10,590 ‫In this lecture, we're going to be bringing in some external assets such as these barrels and crates 3 00:00:10,590 --> 00:00:15,090 ‫and enabling physics on them so we can have a little bit of fun smashing them to pieces. 4 00:00:15,210 --> 00:00:18,180 ‫Let's dive in and see how to get these assets. 5 00:00:18,870 --> 00:00:24,420 ‫So currently the least satisfying thing about our game is the assets within it. 6 00:00:24,420 --> 00:00:30,930 ‫We are they're pretty plain and vanilla and they certainly don't reflect what I want the game to reflect, 7 00:00:30,930 --> 00:00:35,160 ‫which is that this is us wrecking a warehouse with wrecking balls. 8 00:00:35,160 --> 00:00:37,230 ‫So this isn't what we want. 9 00:00:37,230 --> 00:00:38,790 ‫We need some new assets. 10 00:00:38,790 --> 00:00:44,190 ‫And fortunately there is a great integration with the unreal marketplace. 11 00:00:44,190 --> 00:00:49,890 ‫If you open up your Epic Games launcher, get to the Unreal section in the left and then click on the 12 00:00:49,890 --> 00:00:53,010 ‫Marketplace tab in the top tab bar. 13 00:00:53,010 --> 00:00:56,130 ‫Then you can see all of the assets available. 14 00:00:56,130 --> 00:00:59,700 ‫Now, don't worry, I'm not going to be asking you to pay for any of these assets right now, although 15 00:00:59,700 --> 00:01:06,390 ‫I do recommend paying for assets as you get further down the road with Unreal, it really helps supercharge 16 00:01:06,390 --> 00:01:08,790 ‫you into doing more things. 17 00:01:09,030 --> 00:01:13,380 ‫Now, what you can do, however, is you can filter by different types of free content. 18 00:01:13,380 --> 00:01:19,500 ‫There's a sub toolbar in the marketplace section called Free and under that dropdown you can see there's 19 00:01:19,500 --> 00:01:21,960 ‫a bunch of different types of free. 20 00:01:21,960 --> 00:01:26,580 ‫You've got the Epic Games content, which is stuff released by Epic Games themselves off from games. 21 00:01:26,580 --> 00:01:31,470 ‫They didn't release mega scans, which comes from the Epic Games, mega scans acquisition. 22 00:01:31,470 --> 00:01:34,740 ‫Then there is the free for the month collection. 23 00:01:34,740 --> 00:01:39,090 ‫So these are asset packs that if you download now, you can use them for free forever, but they're 24 00:01:39,090 --> 00:01:40,470 ‫only available this month. 25 00:01:40,470 --> 00:01:45,240 ‫Then there's the permanently free collection, which is stuff that has been purchased by Epic Games 26 00:01:45,240 --> 00:01:47,670 ‫to make available for us to use. 27 00:01:47,670 --> 00:01:52,350 ‫So we're going to be using stuff from the permanently free collection and you could go through and have 28 00:01:52,350 --> 00:01:56,940 ‫a look for the basically there's there's over 100 different asset packs here. 29 00:01:56,940 --> 00:02:00,330 ‫There's a really cool one that I like called the Factory Environment Collection. 30 00:02:00,330 --> 00:02:01,620 ‫It looks really awesome. 31 00:02:01,620 --> 00:02:05,070 ‫That's a bit too complicated for what I want to achieve in this section. 32 00:02:05,070 --> 00:02:10,230 ‫However, I do recommend that if you want to take the contents of this section further. 33 00:02:10,230 --> 00:02:14,940 ‫However, what I'm going to be using is an asset pack that I've already downloaded, and if we go to 34 00:02:14,940 --> 00:02:22,170 ‫the library tab and scroll down through the many, many assets that I have got, what I'm looking for 35 00:02:22,170 --> 00:02:27,960 ‫is one called industry and I can filter these as industry props pack six. 36 00:02:27,960 --> 00:02:33,300 ‫That's the one that I would recommend it you get if you want to follow along with what I'm doing in 37 00:02:33,300 --> 00:02:34,080 ‫this project. 38 00:02:34,080 --> 00:02:40,230 ‫Unfortunately, if you are following along on a mac, this particular asset pack doesn't support being 39 00:02:40,230 --> 00:02:42,330 ‫imported into a project on Mac. 40 00:02:42,330 --> 00:02:48,810 ‫But don't worry, I've packaged up a download for you to use and I'll show you how to use it after we've 41 00:02:48,810 --> 00:02:51,570 ‫gone through the instructions for Windows. 42 00:02:52,170 --> 00:02:57,300 ‫So you search for that in the marketplace, you add it to your basket and you have to check out as if 43 00:02:57,300 --> 00:03:00,510 ‫you may even have to enter a credit card even though they're free. 44 00:03:00,780 --> 00:03:06,270 ‫You may have to enter a credit card and you won't pay anything, and then it will end up in your vault. 45 00:03:06,270 --> 00:03:11,580 ‫In the library section, you'll need to click Add to project and if you haven't used this before, it 46 00:03:11,580 --> 00:03:13,020 ‫will have to download it first. 47 00:03:13,020 --> 00:03:16,170 ‫Don't worry, it's not too big, it's only about 200 megabytes. 48 00:03:16,170 --> 00:03:18,930 ‫And then you can go and add to a project. 49 00:03:18,940 --> 00:03:26,250 ‫Then it will come up with this dialog here and at the moment it's defaulting to just showing the compatible 50 00:03:26,250 --> 00:03:27,570 ‫project versions. 51 00:03:27,570 --> 00:03:33,450 ‫But if you want to bring it into a newer version and you think it will probably work, which I think 52 00:03:33,450 --> 00:03:40,140 ‫it will, you can click show all projects and then you can look, we can search or you can look down 53 00:03:40,140 --> 00:03:43,890 ‫through your projects and find the Warehouse Wreckage project. 54 00:03:43,890 --> 00:03:49,560 ‫And then because there isn't a compatible version within the asset pack itself, you have to click the 55 00:03:49,560 --> 00:03:52,380 ‫dropdown to select the nearest version. 56 00:03:52,380 --> 00:03:55,650 ‫And in my case, the nearest version is unreal five early access. 57 00:03:55,650 --> 00:04:00,840 ‫So I'm going to select that one and I'm going to go ahead and add that to the project. 58 00:04:00,840 --> 00:04:03,030 ‫And you can see it shouldn't take very long. 59 00:04:03,030 --> 00:04:05,220 ‫It's doing a little bit of downloading. 60 00:04:05,340 --> 00:04:09,000 ‫So if you're on a mac, this is the process for you. 61 00:04:09,000 --> 00:04:13,980 ‫Now do watch along if you're on a PC as well, because this can be useful to know how you can bring 62 00:04:13,980 --> 00:04:18,390 ‫across assets from another project, not just from the marketplace. 63 00:04:18,390 --> 00:04:25,890 ‫So go ahead and download the Mac Props Zip, which is against this lecture and go ahead and extract 64 00:04:25,890 --> 00:04:26,430 ‫it somewhere. 65 00:04:26,430 --> 00:04:30,660 ‫In my case, I'm extracting it to my downloads folder and when that's done, you're going to end up 66 00:04:30,660 --> 00:04:33,420 ‫with a folder containing a new project. 67 00:04:33,420 --> 00:04:37,800 ‫So double click on that new project to open it in your engine version. 68 00:04:37,800 --> 00:04:43,710 ‫This project version is in Unreal Engine five, so you'll need Unreal Engine five or later, and you 69 00:04:43,710 --> 00:04:45,330 ‫may need to upgrade the project. 70 00:04:45,330 --> 00:04:50,580 ‫When you try and open it, when you open it, you're going to be greeted by this, the default map. 71 00:04:50,580 --> 00:04:51,420 ‫But that doesn't matter. 72 00:04:51,420 --> 00:04:55,680 ‫What we're going to do is we're going to click down in the bottom left on the content browser. 73 00:04:55,680 --> 00:05:01,020 ‫And you can see there is the industry props pack six folder in here, which has got all the same stuff 74 00:05:01,020 --> 00:05:03,330 ‫that was in the asset pack from the store. 75 00:05:03,570 --> 00:05:05,400 ‫So you're going to right click on that. 76 00:05:05,400 --> 00:05:13,080 ‫Then you're going to go to the migrate button and you're going to just check that all these assets are 77 00:05:13,080 --> 00:05:14,040 ‫indeed selected. 78 00:05:14,040 --> 00:05:22,530 ‫You click, okay, and then you need to navigate to your project folder, which in my case is here and 79 00:05:22,530 --> 00:05:24,990 ‫I can go down into the warehouse wreckage. 80 00:05:24,990 --> 00:05:30,900 ‫I need to go down into the same folder that has the new project and then I need to go into the content 81 00:05:30,900 --> 00:05:32,280 ‫folder within it. 82 00:05:32,280 --> 00:05:34,110 ‫Then you can select that folder. 83 00:05:34,790 --> 00:05:37,970 ‫And you can see a successful log message pops up. 84 00:05:37,970 --> 00:05:42,050 ‫And if you go over into your warehouse wreckage project, open up your content drawer. 85 00:05:42,080 --> 00:05:47,690 ‫You should now see the industry props pack six in there like the PC folks. 86 00:05:48,320 --> 00:05:54,890 ‫So once that has downloaded and completely finished adding to the project, we can go back over into 87 00:05:54,890 --> 00:05:57,450 ‫Unreal and have a look at the content draw. 88 00:05:57,470 --> 00:06:02,420 ‫And by the way, you can bring this up with control space as well if you want a quick access. 89 00:06:02,420 --> 00:06:05,600 ‫Now you can see that next to the Starter Pack folder. 90 00:06:05,600 --> 00:06:11,090 ‫If we're in our content folder, there is now an industry props pack six folder. 91 00:06:11,090 --> 00:06:17,810 ‫So we can click into that and we can open up the maps and have a look at the showcase level just to 92 00:06:17,810 --> 00:06:20,540 ‫see what kind of stuff is included here. 93 00:06:20,570 --> 00:06:24,800 ‫Now, for some strange reason, in my version of Unreal, if I just go ahead and double click on the 94 00:06:24,800 --> 00:06:31,370 ‫showcase, it's going to spend a very long time here preparing to load up the level, so I wouldn't 95 00:06:31,370 --> 00:06:32,630 ‫recommend doing it this way. 96 00:06:32,630 --> 00:06:35,120 ‫You're going to be wasting a lot of life. 97 00:06:35,120 --> 00:06:41,420 ‫So what I'm going to do is I'm going to go ahead and just quit this task in the task manager because 98 00:06:41,420 --> 00:06:44,390 ‫I can't really quit it any other way while it's trying to load the level. 99 00:06:44,630 --> 00:06:47,300 ‫And then I'm going to go ahead and reopen. 100 00:06:47,570 --> 00:06:50,240 ‫And once that's open up again, we can go back to our content draw. 101 00:06:50,240 --> 00:06:55,400 ‫And the trick here, I don't quite know why this works, but if you right click on the showcase first, 102 00:06:55,400 --> 00:07:00,710 ‫you can see that in the preparing the right click menu, it's doing a little bit of that work that it's 103 00:07:00,710 --> 00:07:03,050 ‫going to do when we first opened the level. 104 00:07:03,050 --> 00:07:08,210 ‫So what happens is it comes up with the right click menu and then it has this little drop down pop up 105 00:07:08,210 --> 00:07:10,790 ‫at the bottom that says it's preparing shaders. 106 00:07:10,790 --> 00:07:16,670 ‫So what you can now do is you can write, you can just double click on the showcase and it opens instantaneously, 107 00:07:17,150 --> 00:07:22,280 ‫but you can see that the showcase level doesn't yet feature any of the materials. 108 00:07:22,280 --> 00:07:27,440 ‫But as it is preparing the materials and shaders over here in the bottom right, you can see that they're 109 00:07:27,440 --> 00:07:30,980 ‫slowly starting to pop in one at a time. 110 00:07:31,250 --> 00:07:33,920 ‫So there's still more going on with the shaders at the moment. 111 00:07:33,920 --> 00:07:40,280 ‫But right now we can already see the shape and general color of the objects in this scene. 112 00:07:40,280 --> 00:07:45,860 ‫There's a lot of barrels which I think I'm going to make heavy use of some crates, and definitely these 113 00:07:45,860 --> 00:07:49,220 ‫racks are going to be fun to try and knock over. 114 00:07:49,220 --> 00:07:54,770 ‫So let's go back to the starter content map that we were using so far. 115 00:07:54,800 --> 00:08:01,550 ‫So we'll go back to our content folder all the way back up and then we're going to go into starter content 116 00:08:01,550 --> 00:08:04,580 ‫and maps and then minimal default. 117 00:08:04,580 --> 00:08:09,710 ‫And what I want to do is show you just how easy it is to bring in some assets from that pack. 118 00:08:09,710 --> 00:08:15,650 ‫What we can do is go into the content folder again into the industry props pack, this time into the 119 00:08:15,650 --> 00:08:16,850 ‫meshes folder. 120 00:08:16,850 --> 00:08:23,480 ‫And in here you can see all of the assets from that pack, such as these barrels. 121 00:08:23,480 --> 00:08:29,720 ‫And all you have to do is drag one of these into the scene and boom, there you go, you've got a barrel 122 00:08:29,720 --> 00:08:35,870 ‫from that asset pack and you can enable physics and you can do all the things we could do with the other 123 00:08:35,870 --> 00:08:37,190 ‫objects in this scene. 124 00:08:37,190 --> 00:08:40,790 ‫So let's take the challenge of knocking down some assets. 125 00:08:40,790 --> 00:08:46,850 ‫I'd like you to place some assets in your starter content scene, enable physics on them, and you can 126 00:08:46,850 --> 00:08:51,050 ‫potentially tweak the mass or whatever you want to do with them and try knocking them down and see if 127 00:08:51,050 --> 00:08:54,830 ‫you can have a bit of a fun experience from these new assets. 128 00:08:54,830 --> 00:08:56,330 ‫Pause video and have a go. 129 00:08:59,830 --> 00:08:59,980 ‫Uh. 130 00:09:00,070 --> 00:09:06,960 ‫Okay, well, come back so we can go ahead and add a few more barrels of different types and just see 131 00:09:06,960 --> 00:09:08,420 ‫what these are like. 132 00:09:08,430 --> 00:09:16,830 ‫We can also add a box or two, like, so we can even stack some barrels on top of the box, like. 133 00:09:16,830 --> 00:09:22,920 ‫So now if you try and stack barrels on top of barrels at this stage, you're going to end up with a 134 00:09:22,920 --> 00:09:29,280 ‫little bit of a headache because these barrels currently don't aren't very stable when stacked on top 135 00:09:29,280 --> 00:09:29,820 ‫of each other. 136 00:09:29,820 --> 00:09:33,780 ‫But there is a way to improve that and we will be doing that later on. 137 00:09:33,780 --> 00:09:38,340 ‫So we're just going to go ahead and select all of these, make sure in the details pane we have the 138 00:09:38,340 --> 00:09:42,630 ‫physics filter selected and then click simulate physics on those. 139 00:09:42,630 --> 00:09:45,660 ‫Then we can hit play and we can see, there you go. 140 00:09:45,660 --> 00:09:47,790 ‫I told you that those barrels aren't very stable. 141 00:09:47,790 --> 00:09:49,440 ‫They just pop a little bit. 142 00:09:49,440 --> 00:09:52,080 ‫And possibly the fact that our character was in the middle didn't help. 143 00:09:52,080 --> 00:09:57,960 ‫So we're going to move player start back a little bit like so and then we go ahead and hit play and 144 00:09:57,960 --> 00:10:03,390 ‫yeah, they're still not very stable, but we can shoot these things and have a little bit of fun. 145 00:10:03,390 --> 00:10:09,910 ‫This crate seemed way too light for my liking, so I'm just going to adjust its mass and rack, rack 146 00:10:09,930 --> 00:10:12,780 ‫it up to 400 and see if that's any better. 147 00:10:12,780 --> 00:10:18,240 ‫Now, if I shoot the crate a little bit better, I still think maybe a thousand kilograms for that crate 148 00:10:18,270 --> 00:10:19,110 ‫would be enough. 149 00:10:19,110 --> 00:10:20,820 ‫So making it one metric ton. 150 00:10:20,820 --> 00:10:26,550 ‫Now, if we try knocking down the crate, it reacts a lot more slowly and as I would expect a crate 151 00:10:26,550 --> 00:10:28,320 ‫of that size to react. 152 00:10:28,350 --> 00:10:28,860 ‫Great stuff. 153 00:10:28,860 --> 00:10:35,670 ‫We've got a bit more fun going on now in our scene with some of the assets that we've chosen ourselves. 154 00:10:35,670 --> 00:10:37,200 ‫I'll see you in the next lecture.
