What do you have so far for the game over and loose class codes?

I just threw this together. Not tested or anything. Hope it works and/or helps.

That worked. Thanks for your help!

<Code Omitted>The above is not tested -- but, I believe it should work. Be advised that the elements are typed as Actor objects and, as such, the methods or fields that are declared in either of the two classes are not accessible without first casting any of the objects appropriately as the type they actually are (as a läufer or läufer2 type object; you can use the 'instanceof' conditional to check which class the object belongs to).

Thank you! Such an obvious mistake and I missed it!

I do not see anything that would seriously cause any lagging. The suggestion Hippo gave to show the constructors of other classes might help. However, showing entire class codes would be more helpful so as to leave no stone left unturned (if you know what I mean).

It works, thank you very much :)

this code : <Code Omitted>will be replaced by :

This will be a bit complicated, especially since there is scrolling involved. The turn around points need to be fields, not just local variables, so that their values are retained from one act step to the next. Then, they will need to be adjusted anytime horizontal scrolling is implemented. Finally, after moving, the location and direction need checked for each turn-around point to determine if the actor is to turn around.

You have to write an algorithm for that. As long as the flag doesn't change its location and the maze doesn't change in some way, it is enough to calculate it once. I think the best way to do this would be to start at the flag, give it route length 0, the possible neighbor cells are then 1 and so on. And then, when you reach the AI, it will have a route length (X) too and can find the shortest route moving from X to X-1, X-2, ... to 2, 1, 0. You can then save this route in a list, so you don't have to calculate it again and again. I don't have the algorithm in code. Maybe you can find maze sc

THANK YOU

Maybe you can find you answer here: https://www.greenfoot.org/topics/59948/

This is really too general of a question with no given code to work off of (or with). The best general answer I can come up with is, using pseudo-code, something as follows: <Code Omitted>where vertical movement is done with a line of code similar to the following: <Code Omitted>
