WEBVTT 00:00:00.240 --> 00:00:06.640 If you're at all like me, you wear the most sensible footwear on Earth. You 00:00:05.279 --> 00:00:10.719 occasionally get excited about the release of a bigname game title. You 00:00:08.800 --> 00:00:15.679 have at some point in the past heard a friend complain about a forementioned 00:00:12.880 --> 00:00:20.080 bigname game using the same worn out old engine. Or conversely have encountered 00:00:17.840 --> 00:00:25.359 the massive hype train that usually accompanies a shiny new engine. But 00:00:23.279 --> 00:00:30.880 these overly enthusiastic game journalists and downer type friends 00:00:27.680 --> 00:00:35.280 often neglect to explain what exactly a 00:00:30.880 --> 00:00:37.680 game engine is. So here we go. Firstly, 00:00:35.280 --> 00:00:42.640 they provide a rendering engine which allows designers to pair their 00:00:39.520 --> 00:00:45.360 in-housemade 2D images with 3D 00:00:42.640 --> 00:00:50.559 wireframes to create fully actualized models. Then usually one or several 00:00:48.559 --> 00:00:55.520 application programming interfaces such as the upcoming DirectX12 and Vulcan are 00:00:53.360 --> 00:01:00.800 used to furnish the rendering engine with efficient access to a systems 00:00:58.000 --> 00:01:05.439 processing and graphics hardware. Secondly, game engines must provide well 00:01:03.600 --> 00:01:10.159 everything else as well. There's the obvious stuff like physics or collision 00:01:08.240 --> 00:01:14.799 detection engines which account for general movement and the interaction 00:01:12.560 --> 00:01:20.000 between models like you know characters and the ground as well as stuff that you 00:01:18.080 --> 00:01:24.960 might not have considered before like realistic lighting effects with 00:01:22.159 --> 00:01:29.759 realistically bouncing light rays, realistic diffusion through different 00:01:26.960 --> 00:01:35.040 materials, and even crazy stuff like the scattering of light beneath the surface 00:01:32.159 --> 00:01:40.640 of a model's skin to give him natural looking rosy cheeks for example. And of 00:01:37.759 --> 00:01:46.880 course something thirdly has to keep our game subjects marching perpetually along 00:01:43.280 --> 00:01:48.720 the horizon. So AI engines are also 00:01:46.880 --> 00:01:53.439 pivotal to give our characters the ability to create Skynet inside of our 00:01:51.439 --> 00:01:59.360 No, just kidding. Usually an AI engine is more like a complex arrangement of 00:01:56.640 --> 00:02:05.040 behavior trees. But anyway, the point is that a game engine is the sciency 00:02:02.079 --> 00:02:09.840 programming skeleton that supports the game designers and lets them focus on 00:02:07.119 --> 00:02:13.440 the flesh, you know, the story and gameplay elements of their title instead 00:02:11.680 --> 00:02:17.760 of spending countless hours locked away in a room focused on like the sound. Oh 00:02:15.840 --> 00:02:22.800 yeah, don't forget sound and physics of like bouncing balls. Okay, so now that 00:02:20.239 --> 00:02:27.920 we have an idea of what game engines are for, the next obvious question is where 00:02:25.280 --> 00:02:32.160 do they come from? Well, son, let me tell you. When a man loves a woman and 00:02:30.080 --> 00:02:37.120 No, sorry, just just kidding. So, simply put, they come from well, a lot of 00:02:35.200 --> 00:02:40.720 money. There are open source game engines out there, but for the most 00:02:38.560 --> 00:02:45.120 part, no one is building game engines just to help a brother out. And there 00:02:43.040 --> 00:02:49.760 are a couple of main reasons for a developer to build one. Number one, your 00:02:47.440 --> 00:02:54.800 company, uh, let's say Epic, makers of Unreal Engine, or Valve, the makers of 00:02:52.239 --> 00:02:59.519 Source Engine, decides to focus on licensing this engine technology to 00:02:56.879 --> 00:03:03.440 smaller developers rather than trying to make every huge Blockbuster game from 00:03:01.760 --> 00:03:09.040 scratch or even the third episode of a blockbuster game. Number two, your 00:03:05.920 --> 00:03:11.040 company has the resources to absorb the 00:03:09.040 --> 00:03:15.920 multi-year investment into engine building to avoid paying out a 00:03:13.760 --> 00:03:21.040 percentage on future game sales. Blizzard would be a great example of 00:03:17.519 --> 00:03:23.840 this. Or number three, your company just 00:03:21.040 --> 00:03:28.879 can't find the right technology in a prepackaged engine and needs to build 00:03:26.560 --> 00:03:33.760 their own whether they like it or not. So that's it in a nutshell. achieving 00:03:31.040 --> 00:03:38.319 optimal cost efficiency and then in some cases anyway allocating those extra 00:03:36.080 --> 00:03:43.040 resources to other parts of production like paying these guys to do voice 00:03:40.799 --> 00:03:47.840 acting. Something I'm sure we all appreciate. And you know what else I 00:03:44.959 --> 00:03:52.000 appreciate? Fresh books.
