This is a simple example of making a mineable or destroyable object that spawns some rubble after its been destroyed which then disappears
it could also be argued the cubes more explode but thats all tuneable
I'm going to do a bit more like this with extra on the end to have a bit of fun with it and show the practical limitations of what can and can't be done it also satisfies my inner child that wants to see how far some of this can be pushed
