// Helper function to move a Rect's center point
function setRectCenter(rect, center) {
    var size = rect.getSize();
    rect.left = center.x - size.x * 0.5;
    rect.right = center.x + size.x * 0.5;
    rect.top = center.y + size.y * 0.5;
    rect.bottom = center.y - size.y * 0.5;
}

// Helper function to set a Rect's size
function setRectSize(rect, size) {
    var center = rect.getCenter();
    rect.left = center.x - size.x * 0.5;
    rect.right = center.x + size.x * 0.5;
    rect.top = center.y + size.y * 0.5;
    rect.bottom = center.y - size.y * 0.5;
}

// Move the ScreenTransform's anchor center
setRectCenter(script.screenTransform.anchors, new vec2(-0.25, 0.5));
