range

Change line 1 to 'List zom = getObjectsInRange(50, gun.class);'. Drop line 2 and change line 3 to 'for (int i = 0; i < zom.size(); i++)'. Insert at line 5 'gun g = (gun) zom.get(i);' My question is this: unless you plan on spraying all incoming gun.class objects at once, why are you iterating through all the gun.class objects in range with the for loop? The only reason I see use for a for loop here is possibly to determine which gun.class object is closest, so it would shoot at that one.

You will need to track two things within the for loop, that need to be initialized before the for loop. One to hold to closest gun object found, so far ('closestGun'), and one to hold the closest distance of that gun object ('closeness'). As you go through the for loop, compare the distance of the current gun class object with 'closeness' and if it is closer than replace the values of both variables. When the for loop is done, 'closestGun' will contain the correct gun class object. Calculate the angle between 'this' and the 'closestGun' and pass that to the projectile object class constructor, so it can set its proper rotation.
