Sets the values of the tangency values on both sides of the key value.

Note: You can only set key tangents on standard fcurves; all other fcurves return a error (E_FAIL in COM/C++).

FCurve.SetKeyTangents( Object in_vsaTangents );

FCurve.SetKeyTangents( Tangents );

Parameter	Type	Description
Tangents	Array of Doubles	1-dimensional array containing the tangents: LeftTanX, LeftTanY, RightTanX, RightTanY. The LeftTanX and RightTanX must be in key frames and LeftTanY and RightTanY must be valid key values.

JScript Example

/*
	This JScript example demonstrates how to set key tangents on an fcurve.
*/
var oNull = ActiveSceneRoot.AddNull();
var oFCurve = oNull.posx.AddFCurve2( new Array( 1, 10, 2, 20, 3, 30 ) );
// Set Zero sloped tangents on keys
oFCurve.SetKeyTangents( 
	new Array( 
		-0.5, 0, 0.5, 0, 
		-0.5, 0, 0.5, 0, 
		-0.5, 0, 0.5, 0 
	)
