So to get that to work i need to remove PlayerY and the getX() after Azure actor and Vile actor. Is that correct?

Well, you can remove line 2 -- the line with playerY in it. Then, you can use playerX instead of Azure getX() in line 3. With the code being in the Vile class, you only need to use getX() in lieu of Vile getX() in line 3.
Well thanks for the reply but i figured something out afterall, it was just a lot more then just changing a couple lines but it works now.
I only have one more thing and then ill be done
Whenever the player character dies in the "boss fight" is there a error message that "Azure" cannot be found as the boss asks for the position but the character has been removed.
Is there a quick way to say that the boss can test for either "Azure" or the "GameOver" Object so the error does not happen?
if not or if you wish not to awnser then ill just leave it as it is, that is fine too.
public void checkPlayer()
{
if(Azure == null)
{
if (!getObjectsInRange(200, Azure.class).isEmpty()) Azure = (getObjectsInRange(200, Azure.class).get(0)) ;
}
else if (shooting() == true)
{
int playerX = Azure.getX();
if(Azure.getX() > getX() && animSet != shootAnim){
setAnim(shootAnim, 2);
speed = 0;
if(shootingCounter <= 0)
getWorld().addObject(new EnemyVilePlasma(), getX()+90, getY()-34);
shootingCounter = 5;
}
else if (Azure.getX() < getX() && animSet != shootLeftAnim ){
setAnim(shootLeftAnim, 2);
speed = 0;
if(shootingCounter <= 0)
getWorld().addObject(new EnemyVilePlasmaLeft(), getX()-90, getY()-34);
shootingCounter = 5;
}
}
else if (shooting() == false)
{
if(animSet != rightAnim && animSet == shootAnim){
setAnim(rightAnim, 2);
speed = 15;
}
if(animSet != leftAnim && animSet == shootLeftAnim){
setAnim(leftAnim, 2);
speed = -15;
}
}
}
Between lines 6 and 7, insert the following:
else if (Azure.getWorld() == null) return;

That sadly did not work.
Still the same error.java.lang.IllegalStateException: Actor not in world. An attempt was made to use the actor's location while it is not in the world. Either it has not yet been inserted, or it has been removed.
