yes it should repeat for each time the car intersects the oil slick. sorry if that was misleading

Maybe a misunderstanding here. I did not mean each time the car intersects (hits, or first comes in contact) with an oil slick. I meant the continuous intersecting of the same hit. For one car/oil slick collision, there will be some time of interaction. This will most undoubtedly take a number of act cycles. I was asking if these things that you want done, we to be executed once per collision (regardless of how long the intersecting lasts) or executed once for each

Hello. I was recently asked the question on why does move go next to Greenfoot.delay and not under it. I know it acts differently but i do not know the proper terminology to explain.

Please show an example of what you are referring to (definitely not explained well).

Or you can make difrent health bars

If you mean make multiple health bar classes -- not an idea worth considering. Keep it simple. Have one class to display a bar. Create how ever many bars you need from that one class.

how to creat a scenario

Replied to by danpost, over 6 years ago:

Download/install the Greenfoot application. Run it and select 'Scenario>New Java Scenario...'; give it a name and click the 'Create' button and, !voila!, you have created a scenario. Granted, it does not do much (rather, anything); but, you will be on your way. Just add some code (at minimum).

Istouching Method problem

By Ultr0x, with 3 replies.
Last reply by danpost, over 6 years ago:

You are calling moveAround from the constructor, which is executed only once before the created actor is placed into a world.

Are you calling moveAround() in your MoonLander/Rocket act() method?

This question should point you in the right direction to fix the issue.

how to create instance variables

so i checked out that page about variables and ,my question is how to create a variable to keep track of wether the instance is keyboard controlled or moves randomly.

Well, it is either keyboard controlled or not (two possibilities). So, a boolean field in the class of the controlled actor seems to be what is needed. If there is a possibility that the controlled actor might change to be a different instance, then an Actor field in your World subclass could do the trick (or a static one in the class of the controlled actor).

How do I move an object random with a Smooth Mover?

By JamesArnus, with 1 reply.
Replied to by Zamoht, over 6 years ago:

A way to do this would be to randomly pick a direction. Then create a counter and make the object move in the random direction for <counter> act cycles. When the counter hits 0 you pick a new random direction and fill up the counter again.

How do I spawn objects at random locations without risking that they spawn into each other?

<< Code Omitted >> In lines 3-12, I defined some stuff that I need for the if-expressions that come later, but unfortunately, I can´t use getX or getY as the objects haven´t been added to the world yet. Adding the content of lines 3-12 into the if-expression would be too late because I need schatzX, schatzY, wandX and wandY for starting the if-expressions in the first place. Do you have any ideas how to fix this problem?

If this is a grid world (cell size not pixel-sized), then you could just make use of the getObjectsAt method as you add the actors into the world.
