I am trying to make a kill counter but it resets every time a new bullet spawns.

It would help if you documented the classes with comments to indicate what each code set does. Also, it is hard to tell which counter you are referring to. The Plane class codes might be needed as well, since some variables seem to be defined there.

i am programming a game for school at the moment aboout kollisions and as far as i know is getOneIntersectingObject important for that. But i really dont get what de benefits are. wouldnt it not just be easier to say isTouching.

Believe me. As you continue programming, you will find how useful those other collision methods can be. They all have there benefits (and drawbacks).

I am trying to make snake, but i can't seem to get the other parts to follow correctly

Provided the parts of the snake each retain which part it follows, you only need to keep the head and the tail parts in fields. Never move the "body" of the snake. When moving, replace head with a body part and move head. Then, only if not eating, remove tail piece (the tail field needs updated first to the piece the tail follows).

how do i add delay to 1 actor?

I am trying to make a healthbar but the healthbar goes down way to fast, i tried the Greenfoot.delay() but then everything slows down. Can someone help me?

The Greenfoot.delay() method will suspend all actions for the number of act cycles given as its parameter. If the touching of another actor causes the healthbar to decrease, then it is probably true that for each act the touching occurs or continues, the healthbar will decrease. My suggestion is to list objects it touches and only decrease the healthbar when an object is added to the list (and not when the object

How would i go about making an upgrade that is continuous?

Whenever the world changes, how do i make the upgrade *not* reset?

My suggestion is to use static fields for the upgrades. They must be initialized during your initial world constructor only. Static fields are "class fields" which do not reset when a new world is created, nor when the scenario is reset. This is why they need initialized in the initial world constructor. The keyword "static" is added to the field declaration line. For example:

HTML 5 translation error ??

Replied to by tmhscs, 2 months ago:

Try deleting all of your import statements to awt and swing in your classes. Also try deleting lines of code like "frc = ((Graphics2D)getImage().getAwtImage().getGraphics()).getFontRenderContext();" in your Score class. I think many/all awt/swing methods and/or directly accessing AWT images have no TeaVM/HTML5 translation available which causes it to fail when uploaded to Greenfoot's website. Good luck!
