get Global Bounding Box Y
Get the y position of the block's axis-aligned bounding box in the scene's global coordinate space. The scene's global coordinate space has its origin at the top left.
A block with a transform parent is placed where its transform parents are at the current playback time. Its own transform stays static, like that of every other block. For such a block the call evaluates the animations of its transform parents at that time.
Return
the y coordinate of the position of the axis-aligned bounding box.
Parameters
block
the block to query.
