Braid-like time reversal

[Yogr]

@sproingie

All you need to record are positions and state (player/mob is alive/dead, door is open/closed, key is usable/broken). You don’t have to “run physics backward” to do this, just record the positions and states that result. Braid doesn’t look like it even uses a physics engine.

This. Listen to sproingie.

Create a time stack of saved positions/states of each object and pop them off as you reverse time.

I think I mentioned this before: You just need deterministic sim from initial conditions, then you just save events.

This is all made and implemented and works quite well. I am basically just using float arrays to hold all the data.

I’ll post the game that uses this some time in the next couple of months.
