Most people will not go to an unknown or unfamiliar link. Upload to YouTube or just describe what happens and/or is shown here. Are you sure it is compiling repeatedly? Could it be that it is recreating your world repeatedly or you have an infinitely repeating loop, instead? Post your World subclass codes here for review. You may also need to post the classes of any actors you add to your world during world construction.

danpost is right: It is always easier to solve a problem if the error message is given. Here, especially the information which line throws the error, is most relevant. From looking at the source code, I guess that in lines 39, 43, 54 and 58 you actually want to use the images defined in the attributes at the beginning. For referencing variables, you just use the name without quotation marks. So, removing the quotation marks in these lines should solve your problem, e.g.: <Code Omitted> Live long and prosper, Spock47

I think you are now in the position for some refactoring. If I understand your scenario correctly, the robot is the "protagonist", the actor the player controls. So, it seems that the robot is the one that "owns" the money. 1. So naturally the moneyCounter should be moved to the Robot class. <Code Omitted>As you can see, the source code to manage the money counter already got simpl

You must declare a variable before you can initialize it. However, you can place the initialization code on the same line as that which declares the variable. Example is shown in your own code at line 15, which declares the healthG variable as an int and tells java to initialize the field's value to 30 when created for a HealthGirl actor.

Very good! Finally u have learnt it! I m sorry....ignore the above message I m always thankful to u for helping me everytime

How about improving on what you already have?

Try reinstalling

Change line 37 in Oceano class to: <Code Omitted>and add at line 39 in Oceano ckass: <Code Omitted> If creating the new Oceano object in MyWorld class, use: new Oceano(this) or, if in an Actor subclass with actor in world, use: new Ocean((MyWorld)getWorld())

You mention bullet hitting a P1 object, but I only see code for hitting a P2 object.

Change line 6 to: <Code Omitted>

If you want to change the images of all actors in your world: <Code Omitted>

Please provide the code in question (the more, the better).

Oke, thanks for your help

thank you very much

There are the isTouching(Class) and removeTouching(Class) methods.
