New projectile graphics have to be added to Projectl.ids and must be given an unique number, which is thereafter written to the reference in projectl.ids (value+1) at 0x22 and EffectAnimation at 0x26 in each extended header of the spl file.
Currently I have an running version, used like this:
ACTION_IF FILE_EXISTS ~override/Projectl.ids~ THEN BEGIN END ELSE BEGIN COPY_EXISTING ~Projectl.ids~ ~override/Projectl.ids~ REPLACE ~IDS V1.0~ ~IDS~ END AT_EXIT ~SPLAnim.exe override/FWWI501.spl FWAnim01~However this is far from perfect, and does not uninstall. Therefore I would like to request that this feature gets implemented in a future WeiDU build.
The executable written by me and the C source is located here
