Hi, I’m making a simple physic game with Matter JS, you can see here : [http://zanorg.com/phaser/](http://zanorg.com/phaser/)

Just click and a sword will fall, try to click some swords and you will see strange behavior : swords are moving by themself, bouncing or sliding etc…

I used this tutorial [https://www.codeandweb.com/physicseditor/tutorials/how-to-create-physics-shapes-for-phaser-3-and-matterjs](https://www.codeandweb.com/physicseditor/tutorials/how-to-create-physics-shapes-for-phaser-3-and-matterjs) with PhysicsEditor and TexturePacker with default settings.

Am I doing something wrong ?  
Thanks !

Nevermind I switched to Phaser 2 & P2 and it works great.
