Ah, Thanks! Makes sense... don't know why I didn't think of that. Will try in a few minutes...

Are you trying to have two Greenfoot users play against each other on the website? Maybe this scenario will help you.

Count act cycles. Usually 300 act cycles is about 5 seconds. You can simply what you show above to this: <Code Omitted>

That fixed it. Thank you!

You need to upload the image to an image hosting site or somewhere on the web to be accessible here. Better would be for you to explain what issues you are having and posting the relevant code directly here, however.

You could try out my new ScoreControl class; however, it looks like that would take a lot of work to change the class over. On the other hand, it is quite a hassle passing the value from world to world. The way my new class works, is that the control is static and holds one counter value. It also creates an actor to display the value if needed. The class is located in my Combo Support Class Demo scenario; but, I will show a more generic version of it here (to use GreenfootImage objects instead of TextImage objects):

All you need is one long type field and one int counter. The counter is incremented every 10 minutes and the other is to hold the time when the counter is to be incremented next:

Ok, thanks

thanks much appreciated.

You have to change line 27. The first two 0 are the coordinates of the top left corner, the third and forth 0 represent the size of the oval. If it is 0, nothing can be filled. The random color thing could also be done like this: <Code Omitted>

Use double values. Make gravity '0.25' and divide jump speed in half. Also, track the x and y coordinates of the player using double values so there will be no loss in precision when applying such small changes in location (since greenfoot tracks the location of actors using int values). This change is basically what the SmoothMover class (provided by greenfoot) provides to its subclasses.

Was genau soll zufällig geschehen? Sollen gegebene Objekte an zufälligen Orten in der Welt platziert werden oder sollen an bestimmten Orten Objekte zufälliger Klassen platziert werden? Und soll es bei Erstellung der Welt passieren oder während das Szenario läuft?
