Box creation is making the physics pause
Solution 1:
the problem is that in your down event function, you didn't passt the scene as context. I'm to sure which method you are using, but here an example what I mean:
-
If you are using the
input.keyboard.on
way (here the documentation):this.input.keyboard.on('keydown-DOWN', function (event) { // ... }, this); // <- finall *this* is very important
the final
this
is the scene, that you need to pass to the keyboard event-callback. So that thethis
in your functioncreateBox
points to thescene
and not to the browserwindow
