Start with a blank texture in the wad, and in acs you could do something like:
Code: Select all
TEX basemap = getTexture("basemap");
TEX map = getTexture("blanktexture");
textureCopy(basemap, map);
textureDrawPoint(4,4,RGB(255,255,255));
redrawTexture(5, map);
A rundown: grab a base texture of the level layout (like you see at a mall), grab a blank texture, copy the base onto the blank, maybe put a dot for your position or highlight your destination, and tell it to redisplay the texture on the linedef special 5, or something like that.
It's all to theoretical, I havn't done ACS for a long time, and I've been doing a lot of C/C++.
