In the top of the script:
public AnimationCurve curve;
Then the object in the editor have AnimationCurve but without any curve yet:
I want to set one of the curves via the script in the Start.
For example to select this one the most one in the right:
In top of script:
public AnimationCurve curve;
In Start:
public void Start()
{
if(curve == null)
{
curve = new AnimationCurve(new Keyframe(0, 0), new Keyframe(1, 1));
}
curve.preWrapMode = WrapMode.Clamp;
curve.postWrapMode = WrapMode.Clamp;
}
