Look in the Greenfoot API under the Actor class methods and check out what parameters are needed for the 'getObjectsInRange(..)' method. I will tell you this now: it takes more than one!

What does getObjectsInRange(...) return? Compare that with the type of variable you are assigning its return to. (Hint, use a cast, or a different variable type!)

A mere syntactical error; see the correct format: Where int range is the radius around each image in which a predetermined effect will happen. Also, instead of writing if(player != null), try:

Err, no. As I've already mentioned, the return type is wrong. Specifically, getObjectsInRange returns a List - you cannot assign this to a variable of type Player.

1. Errr yes see the Greenfoot API, there was a syntax error seeing as he omitted the range paramater. I wasn't talking about the variable type. 2. Another reason why this is a syntax error is because he tried to assign a list to class (player). Rather, the correct syntax is to use "java.util.List variable = getObjectsInRange(range, Player.class);" as you mentioned.

I'm perfectly familiar with the API. I was pointing out that what you posted was not correct, because it said the 'correct format' included: ... which is wrong (because it tries to assign a reference of type List to a variable of type Player). I think we now agree on this? Also, danpost had already pointed out the parameter problem.

It returns a list containing Player instances. The list won't have anything in it other than Player instances (but it will be empty if there are no Player instances in range). You can check whether the list is empty using the 'isEmpty' method, as per recent post by Omniscience.

Sorry my bad, I meant like can I pick out the closest one and define it as a variable to use it? For example instead of teleporting the enemy to 0,0 it teleports the enemy to the Player.

Again, this is a bit vague. Let's see, you are in the Enemy class, trying to find a Player in range. But you want the closest Enemy class object to be the one to teleport to the Player (not neccessarily this particular instance of an Enemy class object). ?thinking? Maybe this process should be in the Player class (instead of the Enemy class), where you can list the enemies in range, and find the closest one to teleport with enemy.setLocation(getX(), getY());.
