Breaking floor

[bartimeus]

Hi
I wonder if it's possible to make a path that the player uses and which broke when he step on it. In my case I'm trying to make a bridge made of planks, the problem is that I can't walk on it...
So, is there a way to make the player able to walk on the planks, and if it's possible, how can I break them?

Thanks for your answers

Ofc you can , add my skype and i help you out!!
