New example split_long_md3_animation_into_logical_pieces shows how to play subanimations in MD3 files. In a broader context, it shows how to use TCastleSceneCore.ForceAnimationPose
to manually “drive” the animation, picking the animation frames you want.
The MD3 format comes from Quake 3 and it’s used by various games sharing that game engine. In particular I’m a big fan of Tremulous so this example naturally shows Tremulous cool low-poly aliens rendered and animated using Castle Game Engine 🙂
The MD3 file itself doesn’t specify particular animations, it is essentially one long animation that in practice usually contains glued a number of “subanimations” in our terminology. The accompanying animation.cfg
specifies the “subanimations”, where do they start and finish. The example code defined a ready class that loads animation.cfg
, and allows to query and easily play “subanimations” specified there.
If you use MD3 files with accompanying animation.cfg
files, you will find the class TSceneSubAnimations
to be a ready-to-use component that allows you to deal with MD3 animations easily.
If you’re looking into more general “how can I manually control the animation” then look under the hood and see how is the TCastleSceneCore.ForceAnimationPose
used there.
Here’s a quick demo:
