If you are going throught the "list" to do specific things at that time, you could use where 'class' is changed to whatever actor class you wish to cast each item in the 'list' that getObjectsInRange returns (or whatever class you specify in that method). Note: for just re-locating, or removing the items in the returned list 'Object' can be used in place of 'class'. (in other words, they would not have to be cast to the specific actor). Hope this helps. If not, please post back with more specifics on what you need.

Thanks but i'm still a little confused. I'm trying to get a single actor in range that is an instance on an actor called 'enemy' and i'm not sure what to put instead of 'class'?

If you are just checking to see in one is in range, use If you need a reference to an Enemy class object in range, continue with

I tried 'Enemy enemy = getObjectsInRange(10, Enemy.class).get(0); ' but i got an error 'incompatible types - found java.lang.Object but expected Enemy' ?

Do this: The (Enemy) in brackets is known as a cast and what it is doing is turning getObjectsInRange(10, Enemy.class).get(0) (which is a reference on an Object, which is a class all objects inherit from) into an Enemy

That error is probably due to the fact that no enemies where found in range and trying to get an item from an empty list will throw that error. If you first check to see if the list 'isEmpty()' as I said above, and then, if not empty, get your reference, you will avoid the error.

Best practice solution is to do the query only once and save the result in a variable:

How do i cast 'getObjectsInRange(10, Enemy.class)' into an Enemy in a loop ? for (Enemy a : getObjectsInRange(10, Enemy.class)) { // code to execute }

I am not quite sure what exactly you are trying to do. Using that List<Enemy> l = getObjectsInRange(10, Enemy.class); if(!l.isEmpty()){ for(int i=0;i<=(l.size());i++){ Enemy e = l.get(i); //do stuff with enemy e! }} I think that is what you need to do. (Hopefully I have written that out right!). If you need any more info, check out this link HERE This assumes a lists index starts at 0, not 1.
