Undo support (reopen of #53)

[shaiay]

re-opening of pull request #53 which was inadvenrtantly deleted by me. I just wanted to rename my branch ....

Original test from #53:
After some frustrating silly deaths I decided to add an undo function. I takes you back 10 steps, and will also work when you're dead.
I know there is a small chance of it being acepted with it being against the whole roguelike idea, but just in case, I tried to make it as easy as posible to merge.

It works by saving the game/level on hero.idle() to a size 10 FIFO buffer which is written to using a ByteArrayStream.
When requesting undo the game & level are reaf back from the first (oldest) FIFO elemet.

This is really neat. Could you tag a release with an APK in your fork?

[shaiay]

I might just publish on the playstore, although I'd rather have it accepted
to pixel dungeon proper

I mean it might get rejected as it really breaks the roguelike aspects of the game...

Regardless, it'd be cool if you had a release on your fork. I'd love to play and contribute to this.

@shaiay

Watabou does not accept or even really aknowledge pull requests, and this violates the roguelike nature of the game, so the chance of this getting merged is basically 0.

It's a neat idea though.

The patched version is available on the android play-store:
undone Pixel Dungeon

Let me know what you think

Will definitely take a look tonight. Looks pretty sweet. How far back does it go?

[shaiay]

It goes back 10 turns

What I meant is can you undo multiple times?

[shaiay]

I just keep a list of the last 10 steps,, and undo will go to the oldest
step on that lust, so the answer is Yes, you can undo multiple times, but
never go back further than 10 steps than the first time you undo
