Yes, you only need a .map file to use Mbuilder. Your map must have spawn points for allied, axis, and one info_player_start point. Also you must have lights, or "suncolor 70 70 70" in worldspawn. And, you should have a skybox.
it excuses my ignorance but I am new in this of mappear
that one assumes that does mbuild??. because after putting the button ?build map! ?in the folder that I said that it appeared the map to only appears me a file MSDOS and it executes it and it sends errors to me and .pk3 does not leave any either to me nor another thing
"Skybox" is a box that goes around your world and has sky texture. If you only have a room with no windows or doors, no skybox is needed.
Mbuilder makes a ".bsp" file. That file can be used to make a .pk3 file when your map is finished. For now, the .bsp file should be located in your main/maps/dm folder for testing.
Mbuilder uses an MSDOS program to compile your map. If it has errors, it will not make your .bsp file. Tell us what errors you see and we will help you fix them.
I already could do it thank you very much but, I have doubts with doors because the one that I put, listening that is opened but, cannot be seen, and I cannot cross it. and when I make a door, I put a door texture to him but, this texture is of another size and is seen only a small piece of the texture of the door in all the door.
how I can make the texture of the door is as large as the door?
Select the door brush and press "Ctrl + F" to make the texture fit. Also, "Key S" will allow you to adjust the texture. Func_rotatingdoor must also have an "origin" textured brush to act as a hinge.
