How do you draw maps better in Doom builder?

[MeetyourUnmaker]

I'm new to mapping but wow I'm pretty bad at it.

I can't even make small squares.

I can't make switches.

My lines won't stop drawing when I want them to and I keep spawning new lines.

Help?

You can end a series of lines by right clicking in the same spot you want to finish, or by connecting sectors together into a complete shape!

The best thing you can do is read the Doombuilder Guide.

Spoiler

The next best thing would be to watch some video tutorials

However, there is also GZDoom Builder, which has some prebuilt functions to draw ellipses (circles), rectangles, curves, grids, etc.

One trick I learned while watching twitch streams was in vertices mode you can right click and add new ones and drag the lines around at the same time. That means you can start with a rectangle and then stretch it out like silly putty. Great for caves and such.

You are in for some deep basic tutorials, check youtube, there are hundreds of them for each and every thing, even the most basic. Most of it is trial and error though, i learned most by myself. Also remember to start with GZdoom builder, which makes a lot of things easier. You can still watch the doom builder tuts since it's the same program with additional features and improvements in general.

Mapping in Doom isn't really "drawing" like you would with a pen and paper.

When you right click on the grid you start the process of creating a sector. You left click to plot points on the grid, and the process continues until you left click on the point where you started, closing the shape and creating the sector, which becomes a room or a part of a room in your map. You have to attach sectors together like a web to build the floor plan for your map.

To get an idea for what you're doing, imagine that what you start with is solid mass in the center of a planet, then when you create sectors, your digging out rooms from the inside out. Everything is technically indoors (as in there is always a floor and a ceiling to every sector,) the F_SKY flat is used to give the illusion that you're outside.

You can hold shift while left clicking to not make your points automatically cling to the grid, and you can use the [ and ] keys to change the grid size.

Interesting, I never start drawing with the right button. I only use "insert". Maybe I didn't even know that you can do it with the right button, I'm not sure now. What other basics of editing I'm not aware of?

You should first know how to create a sector :
1-Right click to start drawning and left click to stop drawning (You have to close your sector first before stop drawning).
2-Best way to texture your map is Visual(3D) Mode,press "w" to switch to that mode.
3-Now select the walls you wish to texture with your left mouse button' then click the Right button tp select textures for the selected walls (Doombuilder2 only)
*If you're using doombuilder 1 just select and texture the wall . (Press "TAB" for full textures list)

Can't explain more,just visit official doombuilder site, it has few tutorials and also few helpful plugins too.
