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

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>

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.

In GameWorld class, line 17 declares a local variable called s1 which overshadows the instance field declared on line 3. Remove the declaring type on line 17 (the first word) so that the instance field gets assigned the object created.

thanks Dan!!!

Does not help. Invalid parameter; and ";" would be expected before "{".

Call the list items (with the "s" at the end). Declare it as <Code Omitted>Remove the collision code from the item class and put it in the player class: <Code Omitted>Then, you can just use, <Code Omitted>where the list is not empty and n is between 0, inclusive and the size of the list, exclusive; plus x and y are

I am sorry to say that at the moment, I do not have any demos on controlling a car. That would be something to consider. At any rate, your smoothness is not that great. At slow speed, only few angles of movement will be achieved. Also, the turn rate should be governed by the speed -- not just to turn or not turn, but how much turn allowed dependent on speed (no speed means no turn; slow speeds would be close to maximum turn -- minimum radius turn
