Ashley its Simple to calculate sprite size 1241x 452pix half or twice of this value
Now i use sprite.width +1
and
sprite.heiht+1
Imagine about how much need to add pixels to this sprite of size
when i want to object decreased or increased equally?
for example that expression solve this problem sprite.scale -/+0.1 that will be nice and fast as hell
