How do I set mirrored with a sizeable thing ?

Here's my problem, at first my sprite was doing the mirror-thing fine, Left arrow and he was going to the left, right arrow and he was going to the right, you got the point.

But since I did the "Set size to ....", my sprite no longer turns to the left, why's that ? Only the Not Mirrored event works, seems like the Mirrored state is blocked by the Every tick thing

How can I resolve this ? Thanks

Mirroring sets the width to a negative value. If the sprite width is 100px and you mirror it, it becomes -100px. So when you change the size you need to set it to a negative value if you want it mirrored.

Hi, it doesn't work, I did "On left arrow pressed, set size to (-Sprite.Width, Sprite.Height) and it's still locked for some reason

No, in the set size action in your screenshot where you set the width to (320 - (Sprite.X/7)), you need to set it to -(320 - (Sprite.X/7)) if the sprite is mirrored.

In other words:

if not mirrored: set width to (320 - (Sprite.X/7))

if mirrored: set width to -(320 - (Sprite.X/7))

Alright I'm getting close, now it's just that the value doesn't follow, but I'll try to figure out how to do it, thanks a lot
