background_height[0...7];
Returns: Real
This read only variable returns the height of the image that has been used for the background_index of the same array value. Should you need
to make a background fit a specific height, you should change the background_yscale.
if room_height != background_height[0]
{
background_yscale[0] = 1 * (room_height / background_height[0]);
}
The above code will scale background to fit the height of the room.
