Iterating through the whole world?

Hi, want to write a plugin that removes items in chests and other inventory-blocks.

Is there any way to get all chunks or to iterate through all blocks without making the server generating any new chunks?

This plugin should just run one time so removing items on chunk load is an idea that I don't like.

Thank you.

 

You're best off using MCEdit, loading and scanning every chunk on the server will probably lag it out for quite a long time, possibly breaking things.

 

Lags are no problem since nobody will be playing when I run this plugin.

 

There may be another option. You can watch for chunk loading and then scan the chunk. So when any player enters the area, it will clear chests. You could also make a list, where scanned chunks will be saved (not whole chunk, maybe just a position or id - I'm not sure if chunks have an id), so it will not run when not needed. This way the lag should be minimal/none.

 

Can't lag also be reduced with running it on a separate thread, or is this unsafe?

To get the loaded chunks of a world: world#getLoadedChunks();
