static bool EvaluateRootBoneTimecodeSubframeAttributeAtTime ( const [UAnimSequenceBase](API\Runtime\Engine\Animation\UAnimSequenceBase) * AnimationSequenceBase, const float EvalTime, float & OutSubframe )
Remarks
Evaluates the subframe timecode attribute (e.g. "TCSubframe") of the root bone and returns the resulting value.
Since the subframe component of FFrameTime is clamped to the range [0.0, 1.0), it cannot accurately represent the use case where the timecode metadata represents subframe values as whole numbered subframes instead of as a percentage of a frame the way the engine does. The subframe component of the FQualifiedFrameTime returned by EvaluateRootBoneTimecodeAttributesAtTime() may not reflect the authored subframe metadata in that case.
- This function allows access to the subframe values that were actually authored in the timecode metadata.
- true if the root bone had a subframe timecode attribute that could be evaluated and a value was set, or false otherwise.
Parameters
Name | Description |
---|---|
AnimationSequenceBase | Anim sequence for which to evaluate the root bone subframe attribute. |
EvalTime | Time (in seconds) at which to evaluate the subframe timecode bone attribute. |
OutSubframe | Resulting subframe value from evaluation. If no subframe timecode attribute is present on the bone or if it cannot be evaluated, the output parameter will not be modified. |
