<font face="Arial, Helvetica, sans-serif"> I'm using Construct 2, and the problem that I'm facing is that the sprites (and animations) are kinda isometric... so, the handle of the angle is somehow tricky... what I was trying yesterday was to have an invisible circle as the turret, and the isometric sprite pinned to the "turret", get the angle of the tower and compare it to the angle of the aniamtion in order to detect if the animation should go clockwise or counter clockwise... But it didn't work.
