The best way is to add an instance boolean field to the class, similar to how firing was described at the bottom of this discussion page. You will, however, need to use a combination of checks (one for each key):

Thanks I will check those out. Dividing the objects into parts is a great idea and definately something I will use for simple pictures. For more complex pictures its too much work I think..

No - it returns the world that the actor is in, which isn't necessarily the active world. If the actor is not in any world, it returns null (even if there is an active world).

It is often not good to fix these 'non-static variable from static context' errors with making it static. But there are useful moments when to use it. :) Updated Insect Wars and the Bomberman game lately. Right now, I am not working on anything. Sometimes I have an idea and then, I try to add it. ;)

So prety much just add a counter and up it in your method that makes the point disappear. Then call that counter if you want to know how many points have been collected. If you want to ask how much the counters value is from another class just declare it as a public (so 'int counter' outside of any method but inside your class)(not really called public, but works the same) and use newVariable = point.countername. Then just print newVariable or whatever name you gave the variable you want to hold the score. You could allso just print point.countername (by the way, point is your classname for th

Thanks for your help guys, I finally managed to upload the first version, after days without internet. This is the URL to my game: http://www.greenfoot.org/scenarios/12469 You're right, Alwin_Gerrits. But it's kinda strange that teachers won't help much, so I'm really happy that you guys exist :p

Just to clarify -- it is not 'Objects', but 'Object' as the name of the class. An array of Object type will accept all values and objects (provided they are defined and referred to properly). I would think it goes without saying that 'void' is not a valid entry as all elements are 'null' (not 'void') to begin with.

It's the other way around, the first class will be on top of the others, then the second and so on.

Yes, we are working on it. No, I do not know when it will be resolved. :)

Okay, i'll try again, Thanks.

I did find one downloadable 'stickman' scenario here. I believe it was scenario 1017.

Not enough info. What is 'multiplayerspace', as far as being a variable/field? How is it defined?

I came up with the following, where the frequency is around the number of cycles across a 600 pixel wide world: <Code Omitted>The first three lines can be instance fields instead of local variables (or even class constants, if desired).
