Get the new and the old location when a Piston move a Block

Hello,
My plugin give exp/money for breaking/placing blocks and when the place a block he wont give exp because I save his location but my problem is when a player move the block with a Piston he will give exp again.

My ask is , how can I get the new and the old location of a block when he gets moved by a piston?

 

Get it out of the BlockPistonRetractEvent and BlockPistonExtendEvent.
If you get the location with event.getBlock().getLocation(), you should probably get the correct location in both events.

 

I will try this , thanks

 

And with getDirection() you can indirectly get where the block came from.

 

Hm I always get this error message and I dont know why ...

My code on enable :

Code:

pistonMoveBlockEvent pistonMove = new pistonMoveBlockEvent();
 
Bukkit.getServer().getPluginManager().registerEvents(pistonMove, this);

My code in pistonMoveBlockEvent:

Code:

import org.bukkit.event.EventHandler;
import org.bukkit.event.EventPriority;
import org.bukkit.event.Listener;
import org.bukkit.event.block.BlockPistonEvent;
 
public class pistonMoveBlockEvent implements Listener{
 
    @EventHandler(priority = EventPriority.NORMAL)
    private void pistonMove(BlockPistonEvent event)
    {
        System.out.println(event.getDirection());
    }
 
}

EDIT: With BlockPistonExtendEvent work it fine .... only BlockPistonEvent throws this exception ...

 

You want to get the direction out of the Block, so you have to call it with event.getBlock().getDirection().
And the priority is not needed if EventPriority.NORMAL.
You shouldn't use the PistonBlockEvent instead of the BlockPistonRetractEvent and BlockPistonExtendEvent, just forget about the PistonBlockEvent.
