Hmmmmmm... I can't explain it but... I want to make a "rotate the level" type game, but I want the lvl to pivot around where Sackboy is standing, and not just a fixed point. I hope this was easy to understand.

Does Sackboy's position stay the same as the camera rotates or does the camera stay the same while Sackboy rotates?

https://lbp.me/v/qxpqb-7/trailer?p=1&l=12 This is supposedly a rotating 3D camera. Here is where you get it. https://lbp.me/v/qwzp06x/trailer?p=1&l=12

So from what I gather, you're wanting to rotate the level normally, but calculate the movement of the level as if sackboy were the pivot to give an illusion of pivoting? Either that or put a bunch of rotators everywhere! The calculation is pretty simple though if my logic isn't affected by my tiredness. If you have a rectangle with width of 2x and height of 2y and assuming left and down is negative, the center is at (x-y, x+y) at 90 degrees. At 180, the center is at (2x, 2y). At 270, you have the center at (x-y, x+y). At 360, it's back to normal. There's two problems with this. A) The formula isn't consistent it seems (it might be and probably is, but my tired mind doesn't see it) and B) This is assuming sackboy is still. A is solved pretty easily by handling the two parts separately, then negating it. B is a bit more complex. The x's and the y's move as sackboy moves. One (tedious) way to deal with this is to put tags all around the border of your "rectangle" (level boundaries) and have one moving tag sensor for the x and one for the y which will be the scalar for the math. Then you have to worry about the level running into the level borders (which can be solved with emitting) but this is too complex for me to make and show you, but there might be (and probably is) an easier way.
