Solved Log and rollback blocks

Hello Guys,
I was wondering how can I log and then rollback blocks? I know I can log them with the block break event but how do I actually save them and rollback them?

Kind Regards,

Save the necessary block data into a database.

Save block state. Update block states when you want to rollback.

 

I don't know how to save them or which hashmap or what. Can anyone provide me a piece of code?

 

PatoTheBest You see, that's the whole point of plugin development. To figure such stuff out.

What you have to do:
1. Capture the event
2. Log the BlockState or whatever you need into a flatfile/SQL/YML whatever
3. Create a command that would iterate upon the changes in reversed chronological order

That being said, logging plugins can be really complex, with different types of logging, rollbacks that can happen in an area, according to block type, dates etc. It might be a bit much.

I have this code and I want to log all the blocks and then rollback when the game finishes.

Code:java

    @EventHandler
    public void Break(BlockBreakEvent event){
          Player player = event.getPlayer();
              if (ArenaManager.getManager().isInGame(player)){
                  //code
          }
    }

PHP:

List<BlockState> states = new ArrayList<>();

// Listener
states.add(event.getBlock().getState());

// Rollback
for (BlockState state : states) {
    state.update(true);
}

Oh, I didn't know there was a BlockState class. Thanks, will try it out.

 

Note that block states might not properly restore tile entity data (like sign text or check content) if the block changes it's type in the meantime. At least that was an issue the last time I wanted to use them to temporary store and restore blocks which get removed by explosions.

 

Yep, creating a thread for that

 

They won't? I'd think they would, they store the data in them...

@OP For what you're doing I would recommend copying world files for arenas instead of rolling back blocks, it's a lot "safer". But do what you like, I suppose.

 

They don't, check my other thread http://forums.bukkit.org/threads/itemstack-broken.256802/
I tried to temp. save the data but it is wired.

 

They store the data but they don't properly restore it if the block type changed in the meantime (for example for type 'chest' to 'air'). The update method set the block back to type 'chest' but fails to restore it's conent. See this ticket about it: https://bukkit.atlassian.net/browse/BUKKIT-3522
