Привет всем!!! Подскажите пожалуйста как изменить скрипт для рисования мышью

private var origPoints : Vector2[];

function Start () {
    linePoints = new Vector2[numberOfPoints];
    origPoints = new Vector2[numberOfPoints];
    
    // Plot points on a circle
    var radians : float = 360.0/(numberOfPoints-1)*Mathf.Deg2Rad;
    var p = 0.0;
    for (i = 0; i < numberOfPoints; i++) {
        linePoints[i] = Vector2(.5 + .25*Mathf.Cos(p), .5 + .25*Mathf.Sin(p));
        origPoints[i] = linePoints[i];
        p += radians;
    }
}

function Update () { 
    for (i = 0; i < linePoints.Length; i++) {
        if (i%2 == 0) {var m = .4; var t = 1.0;}
        else {m = .5; t = .5;}
        linePoints[i] = (origPoints[i]-Vector2(.5, .5))*(Mathf.Sin(Time.time*t)+Mathf.PI*m)+Vector2(.5, .5);
    }
}

var lineColor = Color.white;
var lineWidth = 3;
var drawLines = true;
private var lineMaterial : Material;
private var linePoints : Vector2[];
private var cam : Camera;

        "} } }");
    lineMaterial.hideFlags = HideFlags.HideAndDontSave;
    lineMaterial.shader.hideFlags = HideFlags.HideAndDontSave;
    cam = camera;
}

function OnPostRender () {
    if (!drawLines || !linePoints || linePoints.Length < 2) {return;}

    var end = linePoints.Length - 1;

        }
    }
    else {

        for (i = 0; i < end; i++) {
            var perpendicular = (Vector3(linePoints[i+1].y, linePoints[i].x, nearClip) -
                                 Vector3(linePoints[i].y, linePoints[i+1].x, nearClip)).normalized * thisWidth;

        }
    }
    GL.End();
}

function OnApplicationQuit () {
    DestroyImmediate(lineMaterial);
}
