I just, for check, create a new project with 1 sprite, and mouse object type.
So, here is the problem.
as you can see, this event works. when I move mouse from left to right, spriter mirror.that's pretty strange isn't? I have a lot of xp on construct software so maybe I learned something new, or it's a bug.
anyway, here, others strange things.
here, the event don't work. the spriter don't mirror on x.
so, what do you think?
