Line 18 did not add one into the world -- that is what line 47 does. The problem is that the Frog object which is created on line 18 is not the Frog object that line 47 adds into the world.

*sigh* Thats what i thought. All right thanks for clarifying danpost. I truly appreciate it. :)

What do you think an addedToWorld(World) method would look like (see Actor class API documentation for clues)?

Good luck with that.

thx dude!

Please explain why you have the FrontImage class extending the BackFront class. Give a full description of what objects of each class are and how they are going to be used.

thanks

Remove line 17, for one thing. You may want to override the addedToWorld(World) method and move line 16 into it.

It is not super weird, and not even surprising. Remember that any action code is executed many times per second (usually about 60). When pressing and detecting a downed key, even if you just tap it quickly, the code will almost always execute two or more times (it takes a lot of time in terms of computer speed for a key to be pressed and released). Therefore, you need another condition (the first being that the key is down) to regulate the spawning of the actor. A second condition that should work might be that no object of the type being spawned are currently in the world.

Thank you.

You use "new" to create an object out of a class. So if CopyOfCrabWorld is the name of subclass of World and you wish to create a CopyOfCrabWorld object (or instance), then, yes -- use "new CopyOfCrabWorld()" to create it. The parenthesis at the end are important also (they are for any parameters needed for its creation).

The flower which is located at (147,447 ) I can't get there with the player controlled with wasd, but I can with the one controlled with the arrows. I have used the same code for both.

Thanks Danpost, i have realized that without creating a reset method the actor will continuously lose lives as it touches the cars.
