You just need an identifier in the combined classes (Tank, Turret and Shell) -- probably an int field to distinguish one from another (using values from zero to three). Add methods to the classes to return the identification number so that other objects can determine which they are.

Thank you! I really appreciate it! I'll let you know if it works!

Remove the line declaring bossHP from the boss class and the line declaring enemyHP from the enemy class. Then, wherever either is used in the two classes, change it (either 'bossHP' or 'enemyHP') to just 'hp'. Finally, declare 'hp' in the superclass and change 'VARIABLE' to 'hp' in that class as well. In other words, you want to declare 'hp' for all instances of the superclass (which include instances of its subclasses) in the superclass. Any methods you might have to adjust the value of the health in the subclasses can also be move into the superclass. Each subclass can set its own st

Need to see the Bird class codes. Indicate which line is line 41.

In this line of the 'randomSpawn' method: <Code Omitted>either decrease the '60' or increase the '100' (or both).

<Code Omitted> Then, when changing the world from an actor in the world: <Code Omitted>

In line 44, instead of x and y, you could use x-14 and y-14.

I have an actor and i have 4 booleans telling if there are walls on the left, right, up or down. then i need to use that in a different actor to know if it can move or not. the actor i need the booleans from.

Like I said before: Change 'getScore()' in the line being inserted to 'score'.

The loop is what is causing multiples to be spawned at once. Use an if statement with a random chance to spawn.

Okay, first thing that needs done is to add variables to hold what movement was done. The character can move either way horizontally and vertically. So, a variable for change along the x-axis and a variable for change along the y-axis are needed. Your act method will now look like this: <Code Omitted>Now, that dx and dy are there,

Reason for the error: The actor is removed from the world and then you are calling a method which requires the actor to be in the world (in this case 'isTouching'). When the actor is removed from the world, the current act method will be finished. I don't really know why you need this code at all. You earlier check for the intersection with the Alien. If you want it to be removed, then remove it there. The 'toRemove' variable also seems to be useless.

Thank you very much. This is working very well now.

My map should have been this (forgot all the commas)... <Code Omitted> It's up to you if you prefer numbers or letters, it should do the same.
