It depends on what behavior you are wanting -- periodic or random timing of shots would be one unknown; if periodic, how often would be another unknown; if random, the possible ranges in timing would be the second unknown.

Why do you want to create so many laser pulses? You could lengthen the pulses and create less of them all the way up to just creating one laser (see my Laser Demo scenario where each line is one Beam object).

<Code Omitted>The code above will move the spaceship when the code is run at a speed of 2. It will also reset the spaceship to the specified location if it reaches the edge of the game world. Hope this helps a bit!

Hi, danpost. I want to addObject "a WaterMelon" to the world programmatically, where should I put the method? The code below is not working.

Try: <Code Omitted>This will get a list of Bee objects in the world and find where that particular bee is in the list. As long as no Bee object is removed from the world, the list should be created the same way every time.

Ok, then I guess problem solved (for now)? If it happens again and you figure out a way to provoke it, please contact us via the support email address (support@greenfoot.org).

Thanks a lot, works great now

Thank you for the response; it works perfectly.

That counter is belongs to your Fields object -- not to your Fields class. You cannot access it through the class; you can only get it by way of the Fields object create by the class -- the World object your actors are/were in. That means you need to retain that Fields object before removing this from the world. Try this:

Is this the same score counter being worked on in your other discussion thread?

Insufficient context given to answer. (what class the given code is in; what b1 and b2 refer to; what error was given; ...)

Thank you so much for that explanation.

You do not need an array of type char. What you need is an array of type GreenfootImage for the images representing the digits of the number. That way you can calculate the length of the final image, create the final image and draw the digits onto it:
