Was just tinkering around with default zombie bots and thought it'd be mega-cool if you could make the coffin brick spawn a zombie when you opened it.
It'd be a coffin that looks exactly like the default one, except a zombie would be hiding inside of it (idle, of course, so you can't see it moving around in the coffin) So then, when you open it, the zombie wakes up and starts chasing you. I just think that would be so neato.
Would also be cool to have a zombie laying down in the laying-down coffin and when you opened it he sat up and got out.
Here's some visual representations of what I am talking about:
coffin
spoopy zombie
spoopy mummies too. sometimes.
