Hi,

I have several nested layers, affected by scale and rotation. Most of the action happens on my main game layer, 2 layers deep from the root. In that layer i have a spaceship, in that layer, a rotating turret, within that the gun image, it’s registration point is used as the bullets spawn location.

I need to convert to bullet spawn point’s on screen location to it’s relative position on the game layer, in a similar fashion to using local to global, but really I need a local to local function, which I’m 99% sure doesn’t exist. Any ideas?

Thanks  
Andy
