Y Units

The Y Units variable controls how a unit is vertically positioned relative to its parent. By default an object is positioned relative to the top of its parent, where each unit represents 1 pixel downward.

PixelsFromCenterYInverted

The followingshows a child ColoredRectangle positioned 50 PixelsFromCenterYInverted relative to its parent. Note that coordinates are "inverted", which means that increasing the Y value moves the object up rather than down. This value exists to simplify integration with engines which may use positive Y as up:
