You can change the speed of the scenario by moving the handle on the speed slider to the right of the Run button or you can set it programmatically (usually in the world constructor) using: <Code Omitted>

import greenfoot. *; public class Healkit extends Actor { long lastAdded = System.currentTimeMillis (); int randomX; int randomY; public Healkit() { randomX = Greenfoot.getRandomNumber (18) +1; randomY = Greenfoot.getRandomNumber (14) +1; } protected void addedToWorld(World world) { if (getOneIntersectingObject(Baum.class) != null ) getWorld().removeObject(this); } public void act() { long curTime = System.currentTimeMillis(); if (curTime == lastAdded + 20

"I Googled it" is always a legitimate answer, assuming you Actually understood it and didn't just copy paste :P Aside from that, that's how I do it as well, for said reason but also because you can never know if there might be a mistake if you don't understand yourself

An act counter would be like this: <Code Omitted>The timer is incremented every act cycle and is dependent on the act cycles which varies time-wise from machine to machine. The '40' suggests something like 3 beats in about every 2 seconds. The '200' would be the number of beats in the entire song. Using the syst

I wasn't sure which one to do, so I went according to the title and figured if there is a problem it will be mentioned, I didn't want to assume this information wasn't known.

Hmm does it

Thank you so much!!!! My tank now navigates reliably.

Thanks a lot

The only thing I asked you to do in the Level2 class was remove 3 lines (24, 26 and 39 in your first code posting of the class). The addTime method needs to be in the Timer class (with appropriate code).

In Math class.

thank you :)

Save its image in a field and set its image to null to make it disappear. Set the image back to the saved image to make it reappear.

What is the for loop supposed to accomplish?
