[r58] Physics Behavior failed after mirror/flip

When you add Physics Behavior to a sprite, then set the sprite mirror/flip,

(e.g.: drag it to opposite side, set height/width to minus number, set mirror/flip in sprite editor)

it's physics behavior will fail.

And if you create hinge on those mirrored/flipped sprites, the game will crash.

Why would you set its height and width to negative values ?

EDIT: Also launching the app as a preview raises an error in the sprite plugin, not the physics one.

Firebug says :

Index or size is negative or greater than the allowed amount

Line 313 Sprite_plugin.js (this.height)

(with or without the physics behavior applied to the object)

Is that using a negative size sprite in the layout view? It should prevent setting a negative size with the set width/height actions, since canvas doesn't support negative sizes.

I followed the steps Gonzdevour decribed:

+ Create a sprite

+ Set its auto mirror/flip property value to "Auto Flip"

+ Set the size property from "128, 128" to "-128,-128" (no message preventing it, negative values stand in the property window)

+ Launch a preview, application stays greyed/white background; firebug raise the error described earlier.

OK, I've disabled negative widths/heights for next build, neither canvas nor physics support it. For the record: auto-mirror/flip work by the object angle, not the width/height, in Construct 2.

As the picture above.

I am trying to make a ragdoll.

Not like C1 BoneAnimation, a hinged ragdoll has no function to mirror/flip itself,

so I tried to set image width negative for mirroring the ragdoll parts manually.

That's why I set width negative in this case.

Now I know setting height/width negative is an illegal operation,

however, if you go image editor to set a physic-behavior-sprite mirror/flip,

like what I did in the picture, it would also cause the bug I've mentioned.

May C2 be the best!

Thanks, I see the problem, should be fixed in the next build!
