I should be studying now :/

Apply forces to a position/object should take the origin of the sprite and not the 0,0.

I haven't noticed this yet, but I did notice something similar.

Scaling. When I scale, it IS on 0, 0. Force seems ok to me (centralized), but scaling is seemingly on a 0, 0 relative rather than center. Any suggestions on that also?

for example, I make a square. I put it in the scene. I add events where mouseover scales it up by 5% and back down when mouse is not over the sprite/object. The scale goes from 0, 0 down and to the right, rather than centered for all edges to scale away equally. Hope that makes sense

Personally, I think the Origin and Centre points should be the same, a lot of extra math for a little offset helping in the object positioning

That makes perfect sense Thank you for the quick reply! I am still reading the tuts and all so Ill figure how to do that and should be all set! It will be great help for me

In the meantime, if I cannot find this information, I will add what I find out to the wiki and if you happen to know how to change origin, let me know if you have time Thanks again!
