When your MyWorld object (or, your world) is created, the initial value of friendClicked is set to zero by line 107 (fields are created and set to their initial values before the constructor is executed). Since a constructor is only executed once per object created, the condition on line 31 will always be true and the else part of that if-else structure will never execute. Anything done after initial creation of an object cannot feasibly be coded in the constructor. Sometimes, some finalizing set-up is required once an actor is added to a world or when a world is

Change ‘world’ in line 20 to ‘getWorld()’. You might want to change ‘projectile’ to ‘new Projectile()’ as well.

Ok works fine now, thank you guys!

Okay. Possible solutions are (1) you could just remove the car collided with; or (2) you could create another class to take the image of collided car and replace the car with it.

Please refer to my Scrolling Tutorial scenario.

That was little confusing -- as what would be the "original world". At any rate, let me explain this way. When you extend a class, what you are doing is creating a union of classes to describe the same type object as the class being extended creates. The extending class can add new possible states (fields) for the object or add, modify and/or remove behaviors that the object can do (by adding

That may be because your location coordinates are stored in int fields. Any fractional movement in both the horizontal and vertical directions is lost when you use getX and getY in a setLocation statement. Retain the location coordinates in double fields and adjust their values so you can set the new locations.
