What is happening right now?

First create a method to spawn one at any random location. Show method here to continue.

Thank you lord danpost :D ! I'll try this out!

Usa: <Code Omitted>

Using just: <Code Omitted>in your Fish class indicates that the method is either (1) in the Fish class; (2) in any one of its super classes (as a non-private method); or (3) in an interface that one of the aforementioned classes implements. Since it (the method) is located in your Level2 class, you need to indicate that that is where to find the method. Actually, it is the Level2 object (your current world object) that "has" the method. It is the score in that world that you want to increment. The getWorld() method will return a reference pointer to that world; however, the returned type is of World -- not Level2. That is, the method to be called must be on a Level2 type object -- not just a World type object. You can adjust the cast type by using (Level2)getWorld() so the method can be found: <Code Omitted>
