static function DrawBezier (startPosition : Vector3, endPosition : Vector3, startTangent : Vector3, endTangent : Vector3, color : Color, texture : Texture2D, width : float) : void

Description

Draw textured bezier line through start and end points with the given tangents. To get an anti-aliased effect use a texture that is 1x2 pixels with one transparent white pixel and one opaque white pixel. The bezier curve will be swept using this texture.

Note: Use HandleUtility.GetHandleSize where you might want to have constant screen-sized handles.

Bezier Line in the Scene View.

// Draws a red bezier curve from (0,0,0) to the transform's position

@CustomEditor (BezierScript)
class DrawBezierHandle extends Editor {
    
    function OnSceneGUI() {
        var width : float = HandleUtility.GetHandleSize(Vector3.zero) * 0.1;
        Handles.DrawBezier(target.transform.position, 
                        Vector3.zero, 
                        Vector3.up, 
                        Vector3.down,
                        Color.red, 
                        null,
                        width);
    }
}

And the script attached to this Handle:

Debug.Log("I have a bezier curve handle attached!");
