Thread ERROR

Well im using a method that in the past versions, works fine for me but wen i do it in 1.7.2 and higher, it crashs saying: Encountred an unexpected exception java.util.ConcurrentModificationException

 

Help us help you.

 

Alshain01 Dont understand you...

 

That makes two of us. You have to give us something to troubleshoot. You've told use you used to use "a method" but I have no idea which of the thousands of methods in Bukkit, or for that matter, Java that your referring to. There is no code to troubleshoot. Nobody here is a mind reader, you gotta give us something.

Code:java

public class Test extends Thread{
 
    Plugin plugin;
    List<Block> list;;
  public Test(String s, Main instance, List<Block> list){
      super(s);
      plugin = instance;
          this.list = list;
  }
 
    public void run(){
 
 
 
            for(int i = 0; i <= (list.size -1);i++){
Block block = list.get(i);
block.setTypeId(1);
 
}
 
 
 
 
 
 
                try {
                    TimeUnit.MILLISECONDS.sleep(4);
                } catch (InterruptedException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
 
 
            }
 
            this.stop();
 
 
 
 
 
 
    }
}

Alshain01 I tried that, but when im doing heavy amounts of changes, the game kick out the current players

 

You really just can't do that. Trust me if there were a way to change large parts of the world asynchronously, WorldEdit would be doing it.

 

Alshain01 With this method i cant do sleeps so it kick players out =P

 

Same thing happens with WorldEdit if you edit too large an area at a time.

 

Pretty much what Jake6177 said. If the biggest most complex world editor out there doesn't do it, there is a good reason why.
