 And welcome this video is part of a series be sure to check out the description in the playlist or the playlist the link to the Playlist in the description of this video to watch well This is the first one was just about where to get the assets you need to to create a doom level again Creating doom levels is fun. It's easy doom is designed so well that even with a little bit of experience You can make something nice out of it But also doom itself is free and open source and if you're have no Experience in game design and development. It's a good place to start it is Has a lot of a large community around it and instead of trying to create a game from scratch to have something already there and Modify it. That's where a lot of people start It gives you a concept of how things work so that in the future when you do want to go create your own thing You already have a basic idea of how things are supposed to work Here we are we're going to be using the Eureka doom editor, which is what the series is about Once you have it installed and you open it up You're probably going to get some sort of level here and it's depending on what what file you have I have the doom to what file is my default what file and if you go up to file You can go to Project manage project and here you can see that you can choose what what file you want to do by default on defaulting to doom 2 But I have all these other ones installed because I have doom doom 2 I have Final doom and then I also have the free doom wads the port source here source support would be whatever doom port that you're going to be using I use PR boom so I chose boom and Map type that's probably only gonna see doom format there, but you can also probably I'm assuming using this for things like heretic another Doom like games and now these resource files here Again when it comes to doom you have two basic elements. You have your executable. It's the program It's the actual game this the the program But then you have your wad file which is all your assets your elements your your textures your Sprites your sounds your music well you can create your own wad files that maybe have new Graphics for sprites in there and new textures and if you want to use those in the editor You can load those here by clicking load and clicking on those so that's first thing I do is set that up and again when you start it up It's going to show this is the first level of doom 2 since that's the wad file that I have chosen let's talk about Doom itself doom Might seem like a 3d game, but it's not really 3d. It's a 2d game and I'm gonna get into the technical aspects of that But it's a 2d game that looks 3d. So it looks something like this when you play But because it's 2d you can't have One level above another so you have steps here in front of us that you can walk up But you can't have a shelf that you can walk under and over There are some things you can do to kind of fake that and cheat that but in general you don't have You can't have multiple levels above each other So the way doom works and this is a concept once you wrap your head around it makes creating levels a lot easier is that Everything is built on sectors and I like to think of a sector as a room. So you have a room and Each room has a floor height and a ceiling height so This is one room here and then this is another room or sector here And it has a different floor height and or ceiling height They both seem to have the same ceiling height if you look over here on the right you can see all your your Aspects for your sectors. So these are sectors. So let's talk about these different modes You can be in in Eureka. So right now we're in sector mode If you come down here to the bottom left You can see mode more in sector mode where we can select sectors and we can change Information about those things you might change in a sector again The floor height the ceiling height the ceiling texture and the floor texture You can also Choose different types, which we'll talk about more in the future, but things like Whether the lights flash Whether the room gives you damage when you go in there and Also things like doors and elevators or lifts our rooms and so they have special settings as well as far as types Another things you have access to when you are creating these as you can give them tags Which we'll talk about more in the future, but that's where you can link different things to that sector and then your your light so if you're The higher the number of the brighter is the lower the number of the darker is basically and we'll look at that more in the Future as well. So that's a quick overview of sectors Let's go down here to mode again and you can see that vertices is another option and that is what you might draw Your sectors with so for example, you can see that each wall is connected by a vertices You probably know what a vertices is if you've done anything 3d or maybe worked with SVG files so We can take those and then we'll talk about this more, but I can draw on now I just added a whole new other sector over here Or I can add to a wall sector here a wall in the sector which the walls are called lines So that's a quick look at vertices. I think that's pretty straightforward We'll come down here to mode We can now choose lines and the lines are the walls and the walls are what have their textures here So if I go into the 3d view here, you can already see a Preview here. I added this little closet over here and brought this wall in so it has a little point right there But now I can choose different Walls or lines here these walls and I can change the texture So there you go. You can see that we have any texture on there because I clicked on it And again, we'll go more into detail on this But basically I just selected it and then found the texture I wanted over here if for some reason this texture box isn't showing when you click on a wall or a line you can click on Texture over here and should bring up all the textures which are broken down into different categories And you can also search through if you know the name of what you're looking for So like if I wanted that wall texture to have a switch on it I can just type in SW and it should show most our switches here at which point I can add a switch But you can see we'll talk more about how to align tech Textures on the walls a little bit better in the future videos But you notice that there's one texture there But if I was to click something like this step over here, you can see that you now have six different Texture boxes here uppers lowers rail upper and upper Well, I guess lower lower rails and uppers so again Everything's 2d and it's all about the wall Ceiling and floor heights. So if I choose this sector here, I'm going to lower the ceiling down some And I'll raise the floor up more and you can see What we've created here We've moved that step up in the ceiling down and you can see these exclamation marks That's because there's no upper texture So let's go back to our line mode here and With these lines Selected we can choose what texture you want So this one you can see it's an exclamation mark now because it's it's visible But we haven't applied a texture to it So I can click that and I can choose a texture like so and now that texture is on the upper I can choose the lower and give it this texture. Oh, I haven't both selected It's just getting different textures so you can see the difference. So we have an upper and lower now These are the backside now this particular wall You can't see your line You can't see the backside and you can see this little line sticking out from the line That's the front and the other side would be the back So if I was to unselect these and select this one You can see that we have upper and lower for this But you don't even see that side when it comes to that wall and hopefully this will all make more sense as you learn More about how it works, but you can see the backside is not selected or it doesn't have a texture So we will select those and give them a brick texture here and I should select this other wall here and Again, we'll just give them all a texture like so so Now those are that's a basic overview of lines. So we've talked about Sectors vertices lines and last thing is things which obviously are the things the Players positions weapons pickups enemies such as that so those are all here and again I can click on one of these and Change it so I can make that a bad guy instead of a gun I can choose this and these are all listed here. You can search through them But you can also go to categories. So if I just want to look at I want to Look at health and armor. I can now I have two things selected. I can make them both med packs And again, we're gonna go over everything in more detail in the future. This is just a quick overview And if I didn't mention it earlier, let's go back to the sectors And I can change the ceiling and floor so I can either click This is the ceiling here and I click here and make the floor of that Another way to do it is if you don't have either of those selected and you click on with these It's going to change the floor if you left click if you right click it's going to change the ceiling so left click Right click left click right click and as far as what you see in the map here Whether you're seeing the floor or the ceiling texture you can change that somewhere. I usually just leave it as the floor Sector rendering so you can render nothing. So it's just lines and You can render the floors you can render the Ceilings I guess you can render lighting so you can see how bright each room is which is helpful if you're trying to fade the light out and sound Which we'll talk about more in the future But you can lock sound through different walls and you're going to definitely want to do that in some cases For right now, we'll just move this back to floors because that's what I work in mostly So that was a quick overview of the different elements Oh, I do want to mention so we clicked on this mode down here and Shows different ones, but you can change the mode with keyboard shortcuts So when I'm clicked in my map view here, I can hit V to go to vertices mode L to go to line mode S to go to sector mode and T to go to thing mode pretty straight forward And that's a lot quicker than coming down to this mode menu here So again S for sectors V for vertices L for lines and T for things I think that's fairly easy to remember So that's quick overview of the basic elements of the interface talk about obviously things more detail in future videos I do thank you for watching and as always I hope that you have a great day
