Wrong section my friend.

 

As far as i can understand u want to make players flag whenever enter the zone. So ur first mistake starts here

public class PvPZone implements ScriptFile

 

 

Wrong implementation

 

See other zones for reference, because this code is just wrong to begin with.

Topic moved to proper section.

[HyperBlown]

Error says PvPZone.java file line 73, what exactly is there?

[Kara]

Your problem is here:

 

if (_cha.isInZone(_zone)) {
  _cha.startPvPFlag(null);
} else {
  _checkTask.cancel(true);
  _checkTask = null;
}

 

Either the _cha is null which i doubt or the _checkTask future task is null.

Do a debug in those 2 variables.

Which pack do you use?
