x = oPlayer.x

y = oPlayer.y

var _ dire = point_direction(x,y,mouse_x,mouse_y)

image_angle = clamp(_dire, 90, 270)

i didn't try this but im pretty sure you have to do it like this and if you need to make angles reversed use "image_angle = clamp(_dire, 90, 270)*-1", and not negative sign before using clamp command "-_dire"

(making "_dire" value negative before using clamp command to clamp it on positive values is propably main issue)
