I'm working on a game project that use an isometric (30 degrees) angle to move a character around with 32 possible facing.

The world view is on the flat screen, I get the destination angle from the character screen position to the character screen destination.

I'm trying to find the right formula to convert that screen angle into an isometric 30 degree angle to select the correct character facing.

How things look like with 2 plans One method that seems to not work

I tried several methods from various post while Googling but nothing is working as expected.

Any idea on the right formula ?

Thanks a lot !
