Recreating 'FallingShapes" demo in P2.js

Hi,

I am trying recreate “fallingShapes” demo (https://github.com/playcanvas/engine/tree/master/examples/physics/falling_shapes) in P2.js.

Here is the somewhat working source code, https://github.com/goldenratio/playcanvas_demos/blob/master/src/falling_shape_p2.js.html
and live demo here, https://goldenratio.github.io/playcanvas/src/falling_shape_p2.js.html

I am unable to get “restitution” (bounce) on sphere to work. Any help is appreciated.

The p2material script is still not fully implemented:

github.com

playcanvas/playcanvas-p2.js/blob/master/p2-integration.js#L250




for (i = 0; i < numMaterials; i++) {
    materialDef = materialDefs[i];


    if ((materialDef.friction === this.friction) && (materialDef.restitution === this.restitution)) {
        this.material = materialDef.material;
        return;
    }
}


materialDefs.push({
    
});
};


P2Material.prototype.initialize = function() {


this.on('attr', function(name, value, prev) {
    this.updateMaterial();
});
};

The integration library needs a little further work in that area before material properties like restitution and friction are fully supported, it seems.
