Check it out in 3D mode and you’ll see we’ve made a set of stairs going upwards, you could use this to create any set of stairs anywhere. Tweak about with the settings, adding a few iterations with a sector depth of 32, increaing floor height of 8. Select just the 128 line, then click stair builder. In your 256×256 room, lets add two vertices to the wall so we have a 128 wide line with 2 64 wide lines either side. Initially we’ll use this like a stair builder, as intended. Moving on, lets look at the other type of stair builder, which I call an “extrusion tool” – instead of selecting a sector and using the tool, select a single line and use it – you’ll notice that now instead of creating a pyramid out of the room, a rectangular step is being pushed out from the wall, perfectly perpendicular from the wall. It happens more often on complex geometry, so just be careful as you go to avoid this, as you could cause problems with your map. One thing to be _very_ careful is having lines intersect – this happens when your sector depth is too large, you have too many iterations. This doesn’t matter what shape you’ve got, if you want a trim inside it, just use this tool! Done! In a few clicks you’ve had the editor draw a trim sector for you. Set it so that the sector depth is 16, 1 iteration, inside the sector, and until all the texturing options, as we can do this ourselves. Lets add a 16px trim around the edge of the room. Simple, right? So back to our 256×256 room. Regardless, use this set of options to choose which textures should be on the upper and lower sides of the steps. Be a little careful with this, leaving it on the default settings will have your step sides lower and upper unpegged, which might not be useful. If you prefer to do this by hand after the tool’s done the line-work, simple un-tick these options. Using these settings you can choose how high each step is, what texture should be on the floor/ceiling of the steps, etc. This set of options is in my opinion the main reason the tool is useful – you can use this for a number of things. You’ll be able to choose how many steps it adds, what depth these stairs should be, and which direction these stairs should go (inside the selected sectors, or outside). Starting on the left, we have the settings of the stairs themselves. don’t be intimidated by this, we’re going to break it down step by step and make it easy to work with. Now, in sectors mode, select the room, then click on the stair builder tool.Ī popup should have appeared with a range of options and settings. To start, draw a square room, say, 256×256. We’ll start with the ‘pyramid effect’ first. This tool can be used to make “pyramids” of any shape, and can also be made to make extrusions of any line. ![]() Okay so now that you have a grasp on the power of the curve linedef tool, lets meet the stair builder. With this you’ll see that 3 vertices have been placed equidistant from each other across the line. Simply select the line(s) you want to divide up, and change the settings as so: 3 vertices, circular, 0 degrees. Now that you have your room, let’s ‘slice up’ the line into multiple portions so you can texture it differently, just like the corridors in MAP01 of Doom 2 (with the tekgren variants) – you could manually draw the vertices, and when working on the 90degree grid, that’s probably just as easy, but what if your room’s at a strange angle? It can be hard to work out equal portions, so let the curve linedef tool do it for you.įor the example we’ll use a 256×256 box, and try to change each 256 line into a bunch of 64 lines. We can use this as a clever linedef splitter. There, we’ve turned a pentagon into a star! Curve the lines using: 1 vertex, fixed circle, 270 degrees. This will create perfect extrusions of the wall, turning your diamond into an “X” shape! Now, draw another diamond, curve the sides with the following settings: 2 vertices, fixed circle, 270 degrees. What we’ve done here is turn our diamond into a circle! Try playing with the settings to get a grip on what does what. It defaults to whatever settings were last used, but for this example, lets set the vertices to 3, hit the fixed circle button, then change the angle to 90. Start by drawing an equal sided diamond, then, in lines mode, select all 4 sides of the diamond and click on the “Curve Linedef” button. Let’s learn how it works by making a circle out of a diamond. The curves can be controlled extensively, by defining which direction the curve goes (inwards or outwards), how many vertices it adds (more = smoother curve) and at what angle the curve is created at. ![]() What better place to start than with the curve tool? This tool curves existing linedefs. ![]()
