WorldStateCheckpoints 1.6.4.r04
(forked with permission from Checkpoints Backup Mod by MightyPork)

WorldStateCheckpoints gives you a way to take snapshots of your SP worlds! MightyPork indicated that he most likely won't be continuing to support his awesome mod, so I got his permission to update it.

This mod requires Forge.

1.3.2/1.4.2/1.4.4 Downloads

- Access the checkpoints menu by pressing F6 (this can be changed on the regular controls screen)
- Save checkpoints (snapshots) of your world.
- Auto-save mode with GUI and configurable auto-save time increments.
- Press Alt + F6 (configurable) to quick-save a checkpoint.
- Go back in time - if you die, load checkpoint.
- Number of checkpoints only limited by harddisk space.
- You can overwrite existing checkpoints if you want.
- You can easily delete checkpoints.
- When you delete world, all it's checkpoints are deleted automatically.
- Complete world is stored, including all dimensions and inventory.
- Automatic version checking - never miss an update.

ATTENTION: bspkrsCore is a REQUIRED dependency mod in order for any of my mods to work. It contains the core shared classes used by all mods I release. If you don't install it along side any of the other mods here, Minecraft will crash. You have been warned.
ModLoader/Forge download: All Releases

This mod contains core classes used in all other mods I release. If you want to turn off update checking for my mods, you will need to set allowUpdateCheck=false in mod_bspkrsCore.cfg.

Notable differences from MightyPork's original mod:
- no base class edits (that means the in-game menu is unchanged, and no extra buttons on the game-over screen, but should make it compatible with just about every mod)
- requires ModLoader or equivalent
- open the WorldStateCheckpoints menu using F6 by default (configurable from the controls screen... hard to see due to ModLoader bug where it shows up under the Done button)
- fixed issue when loading a checkpoint where newer chunks wouldn't be removed

Known Issues:
- every once in a while in my testing I noticed if a lot of changes are made and then you load a checkpoint real quick right afterwards, sometimes the changes are not reverted. I think this is because the chunks are still saving, but if you load the checkpoint again it will almost always fix it.
- if your actual world name (not the checkpoint name) has special characters in it (specifically "!", but maybe others), it can cause issues when saving/loading/deleting checkpoints.
- try not to end your checkpoint names with a period. I will add code to disallow this in the next release, but for now just avoid using periods at the end of a checkpoint name.

Where are snapshots saved?

.minecraft/saves/Your World/checkpoints/YYYY-MM-DD_HH-MM-SS!Checkpoint name

They don't use any special format, so if your world folder gets corrupted (or world folder deleted), you can place your backed up snapshots into "saves" folder in minecraft and use them as normal world.

- MightyPork (for making an awesome mod and letting me continue it) Give him some love!

I'd like to use this mod in an adventure map as a checkpoint.
Is there a way to save the world with a command block linked with a pressure plate?
Can I disable the save menu?
And also, can this mod auto-load the last save on death?

I just realized something that you missed! the ability to restart from a checkpoint if you die in hardcore mode! very useful for things like ragequit holidays, when you need to restart every 30 seconds.

You can. Just press F6 and if you have any checkpoints saved it will bring up the load screen.
