Animation Looping

From ModEnc
Jump to: navigation, search

The animation looping control code is pretty confusing. The loop control allows to set start/end frames for the first iteration of the loop, and start/end frames for all other iterations together.

  • Start defines a 0-based index of the first frame to play on the first iteration.
  • End defines the 0-based index of the last frame to play on the first iteration.
  • LoopStart defines a 0-based index of the first frame for all following iterations.
  • LoopEnd defines a 1-based index of the last frame for all but the first iterations. The first iteration will never play frames beyond this one, even if End is set to do so.
  • LoopCount defines the total amount of iterations to play.

Example

If you imagine two animations with code like this:
Looping control example schematics
[ANIMA]
Start=1
End=9
LoopStart=2
LoopEnd=10
LoopCount=-1

[ANIMB]
Start=3
End=7
LoopStart=3
LoopEnd=9
LoopCount=-1

, then the scheme on the right depicts the frames that will be played for ANIMA (upper/black scheme) and ANIMB (lower/blue scheme). Upper scale shows 0-based indices, lower scale shows 1-based indices.
