*************************** What is it for? *************************** Declare here the new sprites you want to put in a PWAD ALL THE FILES PUT HERE MUST BE DECLARED IN THE PWAD CREATION DIRECTIVE. Suppose you want to put SPOSA1.BMP and TROOB2.BMP as a new floors and ceiling, just declare it in the FLATS part, like: Begin: SPRITES SPOSA1 TROOB2 End: SPRITES and DeuTex will look here for SPOSA1.BMP and TROOB2.BMP TO MAKE USE OF YOUR NEW SPRITEs, YOU MUST MERGE YOUR PWAD WITH DOOM.WAD There was a limitation with DOOM 1.2. there shouldn't be with DOOM 1.666 but as I couldn't make it work myself, I'll better warn you the SPRITES inserted here will not crash DOOM if used as PWAD (because I don't use the regular S_START S_END delimiters that confuse DOOM) If your PWAD is used regularly (without merging in IWAD) there should be no crash, but you won't have your sprites!
