If the 'wheel' of blocks has no breaks between them (there is no space between them), then the wheel on a whole can be treated as a large ball that the pong ball will bounce off of. The rotation of the block contacted should give the actual angle between the two centers (within reason). The calculation for the bounce should be fairly straight-forward.

You either need to have a tracksbutton instance in the world, so that getObjects(...) returns a list with an item in it, or you need to maintain a separate reference to the tracksbutton object (in a variable), set that at some point, and use it instead of getObjects(...).

The problem is that your countdown is in the constructor of the world. So it is only executed when the world is built. You have to write the code for the timer (everything after super(...);) into the act method.

probleme solve :-) i wrote this, that did the trick :-)

Great! That was, what I was searching for! Thank you, Busch2207!

Timers are useful only to regulate the rate of speed at which something happens and are not necessary in creating automatic movement to begin with. The running of the scenario, with it executing all act methods on all active objects repeatedly will create the 'loop' required to continuously have your actors do something. For example, just by creating an 'act' method with a simple 'move' statement will cause your actor to move toward the right until it hits the edge of the world just by starting the simulation. <Code Omitted>This repe

It works, thank you!

You really do not need a return method, in this instance. It could have been coded as follows: <Code Omitted>

This is partially true. You'll also need to do a cast to the correct type. Change this: <Code Omitted> to this: <Code Omitted>

So who do I decease the number of lives when my actor gets hit

Ok thanks, gives me a lot of possibilities :DD

Oh ok. So when your actor intersects the other object you have to pick it up: <Code Omitted> Then you have to add one to the counter. There are serval ways for doing that. That depends on how your code looks like at the moment: Have you got only one counter object in the world? Have you got a reference to the object in your world class?

For one thing, the variable is defined in the MineBoard class, not the GWorld class, so the variable gameState doesn't exist in the GWorld class. That's why you get "cannot find symbol". For another thing, the variable isn't static, but you are accessing it via a class name instead of via a reference. Try: <Code Omitted>

i just need the coding:)
