When I want to use a method from another class you can simply write Classname.Method() ?

Only for static (class) field -- not for instance fields. Be aware that class fields only reset when the project is recompiled -- not when it is reset.

Can I use the score variable in my world like for example the player scores 1000 points and then enemys stop spawning and a boss will spawn.

You can use 'CopyOfSchusss.getScore()' from ANY class within the project.

And my last question (probably for a long time) I added a powerup (a rocket). The player can sh

You can't use 'label' before the variable is created. Line 8 should be after line 10.

getImage().getHeight()/2

(commented on Sample Platformer) wat does the blue box do

The blue box is just a sample box. You can press the 'h' key to hide the box and have it set what random object it will spawn. When hidden, you can pass through it except when hitting it from underneath, when it will become visible and spawn a random object to collect (I just created a Coin object and changed the image to show what random value was selected). It would be just as easy to have a specific value held by the box and spawn a specific type object when hit. In the sample, you can repeatedly spawn

I think you only need change 'Actor' in the first line to 'Wuerfel'. However, if that does not work, try this in place of your first two lines: <Code Omitted>

problem with counter

By sunshine1, with 1 reply.
Replied to by danpost, over 9 years ago:

It is not enough just to have a Counter object in the world. You need collision detection between the ball and the gates and a reference to the Counter object so that you can call a method on it to adjust its value. If each gate is to score separately (not add to the same score counter), then you need a second Counter object in the world as well. If this is the case, you will need to reply for help on how to assign a counter to each gate.
