index | The index of the key to move. |
key | The keyframe containing the new time and value. |
int The index of the keyframe after moving it.
Moves the key at index
to key.time
and key.value
.
This method removes the keyframe at index
and inserts the updated key
at the correct sorted position in AnimationCurve.keys.
Use it to move a keyframe in two dimensions (time and value).
Notes:
- In order for this method to behave as intended, you are expected to acquire the key using AnimationCurve.keys, modify the value and/or time, then invoke MoveKey
with the updated keyframe. If used with a completely different keyframe, this method essentially replaces the key with a new one.
- Since AnimationCurve does not support having two keys with the same time, in the event where key.time
conflicts with the time of another keyframe, key
will be reinserted at the time of the keyframe at index
, cancelling the move operation in the time dimension but keeping the modification in the value dimension.
- This method is used by the Unity curve editor to implement Keyframe dragging.
