scummvm/engines/kyra/wsamovie.h
Florian Kagerer dd84aaf648 LOL: - added some spell casting (spark, heal, swarm)
- fixed several bugs (not the one in the fighting system though)
- added several opcodes. there shouldn't be any real show stoppers in the draracle cave now.
- simplified wsa code (which required 4 lines of code for displaying a frame)
- added support for wsa animations that don't have a last frame (apparently kyra 2 and 3 don't have this type of wsa file)
