This variable controls the scaling along the y axis of the given background number.



Returns: Real


This variable returns the y axis scale of the image that has been used for the background_index of the same array value. The default value is 1, but this can be set to other values to stretch the background image.

NOTE: You cannot scale backgrounds in any way when using the HTML5 target module without having first enabled WebGL (in the Global Game Settings).


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.

Back: Backgrounds
Next: background_index
