I need help with two things: First trying to figure out how to make a bullet follow a certain object. I have the bullet class made and is able to shoot fine, but how would I make that it heads towards the nearest enemy. and Second, I have this spaceship that flies across the screeen and drops rare items, but I would only like him to drop them in two locations. How do I tell him to only drop at these X and Y coordinates?

for your second question you just have to do a if condition. Something like this: if (getX() == locationXyouWant && getY() == locationYyouWant) { dropItem(); }

You will need to use a 'while' loop using conditions that while no enemy actor is yet found and while the range being checked is less than the greater of the width of your world and the height of your world. Before the loop, declare two local fields; one to hold an Enemy object initialized to null and the other to hold the current distance that you are checking for enemy in initially set to a small number. In the loop, set the Enemy object field to what is returned by using 'getObjectsInRange' with the current distance value; then add a small amount to the distance. After the loop, you will either have 'null' or an Enemy object in your Enemy object field. If it is not null, use its location to 'turn' the newly created bullet in that direction.
