Is there a way to create multiple bitmaps which can be rotated without using panels? (For a 2d game)

No, that's where panels are for.

Your answer is wrong... of course its possible just i'm not sure how.

I was thinking of taking a bmap then recording each pixel then times each vector by a rotation matrix.

If panels is the only way... can you produce panels on the fly?

Well yeah, maybe it's possible in a huge workaround but why wouldn't you use panels? They handle the rotation, scale, position, you name it -math for you.

You can easily make panels on the fly using pan_create.

because... i need a lot of them... would it be more efficient to code a lot of panels or my own function to handle rotations.

never mind... no one told me about the pan_create function.
