| clip | The animation clip to which the curve will be added. |
| binding | The bindings which defines the path and the property of the curve. |
| curve | The curve to add. Setting this to null will remove the curve. |
Adds, modifies or removes an editor float curve in a given clip.
Unity automatic combines position curves, scale curves, rotation curves internally. Thus transform curves always get combined and their keyframes is always the union of all keyframe points. In the Editor AnimationClip's let you specify special editor curves which do not get combined, thus it lets the user edit curves in a more intuitive way.
Unity has two types of animation: Float and object reference. Float curve is a classic curve that animates float property over time. Object reference "curve" is a construct that animates object reference property over time.
This method is used for float curves. For object reference curves, see: AnimationUtility.SetObjectReferenceCurve.
