Map format

(Dodo) #1

I am assuming that the map (.map not .bsp is what im talking about here) format for rtcw is the same as for quake3. I am also assuming this is a good place to ask someone to explain the map format, like what all the crazy numbers mean. Heres a small map file for someone to look at if need be:

// entity 0
{
	"classname" "worldspawn"
	// brush 0
	{
		( -64 64 8 ) ( -64 -64 8 ) ( -64 -64 0 ) radiant/notex 0 0 0 0.500000 0.500000 0 0 0
		( 64 64 8 ) ( -64 64 8 ) ( -64 64 0 ) radiant/notex 0 0 0 0.500000 0.500000 0 0 0
		( 128 -64 0 ) ( 128 64 0 ) ( 128 64 -8 ) radiant/notex 0 0 0 0.500000 0.500000 0 0 0
		( -64 -320 -8 ) ( 64 -320 -8 ) ( 64 -320 -16 ) radiant/notex 0 0 0 0.500000 0.500000 0 0 0
		( -64 -64 64 ) ( -64 64 64 ) ( 64 64 64 ) radiant/notex 0 0 0 0.500000 0.500000 0 0 0
		( 64 64 0 ) ( -64 64 0 ) ( -64 -64 0 ) radiant/notex 0 0 0 0.500000 0.500000 0 0 0
	}
}

I am interested in this info as I would (dont laugh at me) like to make my own game and seeing as radiant already exists it would be good for making things. As far as I know the numbers are co-ordinates for the brush (why are there only 3, shouldnt it be 4 per face?) and the other numbers are texture co-ordinate and also theres the texture of the face. A more detailed explination would be helpful. Thank you in advance.

from what i can work out from A level maths you can store a 3dimensional plain with three cordinates as although you draw, the simplest 3D plain you can have is a triangle. open rtcw and make it draw outlines of the brushes, you will see that square brushes are now triangles,

so now i have time to write something ill tell u what it means

(x y z) coordinate of a vertice
(x y z) (x y z) (x y z) gives three verticies whith is enough to give the 3d triangle in 3d space

then radien/notex is the texture used on that plain and the numbers after it describe its rotation scale etc

You should definately ask this question again in the Q3Map2 Support Forum. I’m sure, ydnar will bring some light into this.
This RtCW forum isn’t that frequented anymore.
