Scale X=-1 breaks collision physics

[ufukbakan]

After setting scale.x to -1 my character goes through other colliders, can we fix this

@ufukbakan Thanks for the issue! This is definitely unexpected, my guess is there are some flipped normals in the collider geometry when this happens causing the errant behavior.

Are you using scale.x = -1 to flip the graphics? If so, one workaround might be to use Graphic.flipHorizontal https://excaliburjs.com/docs/api/edge/classes/Graphic.html#flipHorizontal

I was scaling actor itself not the graphics (because i didnt want to loop all graphics and flip each of them) but it broke the physics so i had to loop each graphic animation to flip them

@ufukbakan Would a new feature on the graphics component to flip all the graphics associated with the actor during drawing be useful?

Something like

const actor = new ex.Actor({...});

// Flips during drawing but doesn't 
actor.graphics.flipHorizontal = true;
actor.graphics.flipVertical = true;

Yes, i think it will be, so we dont have to define runLeft, runRight, jumpLeft, jumpRight, idleLeft, idleRight, attackLeft, attackRight... Just we will able to define run, jump, idle attack graphics and flip graphics if facing left
