Last reply by schetefan24, almost 11 years ago:
right idea... it's static... in an earlier version I needed the variabel to be static, because I tried to set it from an actor class (it failed, now it's running on another way) thx, now I can clean up the code :D (I will have to hand it in, because it's a school project)

which error message? I think that you are checking a coordinate out of the world in the moment when you crash the wall (however it looks like) look in your code for a statemant that adds something to your position and is checking what there is auch gerne nochmal auf deutsch ;) ich geh mal davon aus, dass deine Wand am Rand der Welt ist. wenn du in deinem Quellcode jetzt irgendeine Passage hat, die deine aktuelle position verwendet und noch etwas dazu addiert (oder abzieht), dann kann es passieren, dass er eine position außerhalb der Welt aufrufen möchte, was zwangsläufig zu einem Ab
Need Help Handling Collisions

Last reply by gajurgensen, almost 11 years ago:
I just realized I forgot to add something to my original post. I use methods like 'setRealLocation()' and 'getRealX()' because my game scrolls, and I use 'realX' and 'realY' as my real coordinates in the game and regular x and y just as the position on the screen. Not really relevant to my problem, just to understanding the code.

Variables between different worlds
By mattjames, with no replies.
Hi guys. I have been trying to get a menu to work that when you select an option it gives you a specific object on the game world. The button is in one world and the object that I want affecting is in another world. Having looking at and followed the tutorial on importing variables from classes, it tells me that the button cannot be cast to the other world. Has anybody got any code which will help me with this? Thanks

The second problem is that you try to compare the two images using == but this only works for int, double, char, ... not for objects.
That is not exactly true. It does work for objects also, but they have to be the exact same object (referencing the same instance of a class). Look at the code I provided above, at all times after the constructor is executed, the set image IS either 'image1' or 'image2' and the checks for them will work. The problem occurs when you try to compare something like 'getimage()' with 'new GreenfootImage("turtle1.png")'. Even if the
