Hello guys,
I've got a NullPointerException problem I can't seem to solve.
Whenever I get close to an enemy I get the error (they are spawned to the right side & upper side of the spawn).
Thanks in advance,

You probably will not get much help unless you either upload your scenario on this site or show the code you are using in the discussion thread.
Just done it,
This is the new link to the scenario
Thanks for the advice danpost
Line 15 in the Enemy class assigns dungeonWorld a value using 'getWorld()' which has a value of 'null' at the time the assignment takes place. The assignment of the fields take place during the construction of the object and the object is never added into any world until construction is complete. To assign the proper value to that field, you need to make use of the 'addedToWorld' method supplied by the Actor class.
The 'addedToWorld(World)' method is automatically called by the system when the object is added into a world; so, you do not have to call it programmatically.
public void addedToWorld(World world)
{
dungeonWorld = (Dungeon) getWorld();
