a matrix isn't a matrix's matrix
it isn't at all as in the film matrix
a matrix is a ground
only a ground
not less
not more
try this code :
load image "chooseatexture.jpg",1
create matrix 1,1000,1000,50,50
randomize matrix 1,15
prepare matrix texture 1,1
position camera 200,50,200
point camera 1000,0,1000
sync
wait key
you can see what is a matrix
now, run half-life, choose internet games, choose cs, dod or tfc, and join a game .. all what you can see excepted the others players is a bsp, the bsp is a map, it can have a ground, walls, doors, ......
if you want to make a fps, you should use BSPs, and for a strategy game matrices
