I have a coin counter, every time I take one, this is the account, how do I multiply its value?

Hola

Use Actor type objects to display clickable text. Use World objects for different screens (probably).

Need codes for Robby2 constructor and for randonSpawn method.

It seems that "this.paddle" is null. Therefore: 1. Please give the source code where the constructor is called (new Ball(..., ...)). (if the first parameter is null, we found the problem) 2. Please change the line "public Paddle paddle;" to "private final Paddle paddle;". This ensures that the constructor is the only place "this.paddle" is set (otherwise one would have to check whether paddle gets changed somewhere else in the source code).

Never mind, I figured it out.

sorry to say I decided not to submit anything and fail my course. I just lost interest in programming :<

Add instance fields to the class of the character to signify that (1) potion was touched; and (2) coin was picked up. Use them to control the behavior of the character in the act method. Attempt some codes and if you run into trouble, show codes attempted for assistance.

Try the following field in your MyWorld class (or your game world class): <Code Omitted>with the following line in your MyWorld constructor block: <Code Omitted>and the following in your MyWorld act method: <Code Omitted> Then when policeman collides with coin, set the field to some positive value -- 60 units per second of stu

Oh, okay and thanks a lot for the explanation and all

Thank you SO much it works perfectly

Thank yall for the answers. I got an easy solution but the explanation is very helpful :)

Thanks! I'll try and see how it goes.

Please elaborate in detail and show any attempted codes.

Do not use the wait method within greenfoot. It is a thread operation and may mess up the execution of greenfoot itself. Use: <Code Omitted>
