How do I Make An Object Smaller With 'Distance'?

So I'm just making a small game for fun and would like to make it seem like the game has distance,like when the sprite goes up,it gets smaller,sort of like in the mobile game Cartoon Wars.

I think the 'set scale' action could do the trick but I don't know how to really use it.

Thanks in advance,DoT

Measure the x y coordinates of the sprite on the layout, if x y start to get larger reduce the sprite width and height by a bit.

Also note that the Y coordinate gets smaller (not bigger) when a Sprite goes up.
