move_toward, rotation and radians - Lemmy.world

So, I’m trying to rotate the player as they turn left and right in a top down view. The rotation works correctly when moving right, but fails going left. Here’s the code that handles the rotation rotation = move_toward(rotation, PI / 12 * direction.x, PI / 2 * direction.x * delta) The numerical values look right, giving me 0.261 rads going right and -0.261 rads going left … but the rotation going left continues to go clockwise and stops just before a full 180. Is there some quirk with rotation that I’m missing? My rubber ducks have remained silent.
