AnimationCurve modification

Animation
1

i’m having trouble changing the value of a Keyframe’s inTangent or outTangent at runtime.

Is there a method to change a keyframe’s tangents without deleting/re-adding the keyframe?

static function MakeLinearCurve(c : AnimationCurve){
	for(i = 0; i < c.length-1; i++){
		k1 = c.keys[i];
		k2 = c.keys[i+1];
		k1.outTangent = (k2.value - k1.value) / (k2.time - k1.time);
		k2.inTangent = (k2.value - k1.value) / (k2.time - k1.time);
		c.RemoveKey(i);
		c.AddKey(k1);
		c.RemoveKey(i+1);
		c.AddKey(k2);
	}
	return c;
}

i dont like it :stuck_out_tongue: but it works.
