One thing I often wished was the ability to change the texture of a sector dynamically. Boom allowed this using a model sector. It can be done in ZDoom now, with a simple set of specials. Figure 1 shows a pic before and after a texture change in the demo wad texchg.wad.
In the demo wad a switch activates the following script:
script 1 (void) { ChangeCeiling (1, "TLITE6_6"); ChangeFloor (1, "FLAT22"); }
Two different specials are used to change the texture, but both of them use the same parameters.
ChangeCeiling sector-tag, texture-name
ChangeFloor sector-tag, texture-name
This is almost too easy. Even though simple to use, these are powerful specials and adds another set of tools to the level designer's toolbox.
