ldk_keyframe_animation_track_add
Create a track for an editable reflected component field.
LDK_API i32 ldk_keyframe_animation_track_add(
LDKKeyframeAnimation *clip,
u64 path,
u32 component_type,
const char *property_name
);Parameters
LDKKeyframeAnimation *clip- Animation clip instance.
u64 path- Hash relative to the animation source root.
u32 component_type- Runtime ECS component type.
const char *property_name- Persistent reflected field identifier.
Returns
Track index; existing track is reused, -1 if unavailable or unsupported. Note: Reflected component metadata must be registered when authoring.
ldk_keyframe_animation_track_find
Find a track identified by relative path and reflected field.
LDK_API i32 ldk_keyframe_animation_track_find(
const LDKKeyframeAnimation *clip,
u64 path,
u32 component_type,
const char *property_name
);Parameters
const LDKKeyframeAnimation *clip- Animation clip instance.
u64 path- Hash relative to the animation source root.
u32 component_type- Runtime ECS component type.
const char *property_name- Persistent reflected field identifier.
Returns
Zero-based track index, or -1 if not found.
ldk_keyframe_animation_track_remove
Remove a track and all of its keyframes.
LDK_API bool ldk_keyframe_animation_track_remove(
LDKKeyframeAnimation *clip,
u32 track
);Parameters
LDKKeyframeAnimation *clip- Animation clip instance.
u32 track- Zero-based track index or track description.
Returns
True if the track existed. Later track indices shift.
