never mind found it

If the Squggly object is to follow the Robot object and 'space' is the key then

thanks! I'll see what I can do to remove the GUI.

I am a little confused, however. In the method getFreeRooms() you are looking for values equal to zero, where in getFreeRoomsAround(int, int) you are looking for values NOT equal to zero. That 'for' statement we were looking at in your Gen() method earlier should probably be a 'while' statement <Code Omitted>and in the first line after that 'int rand = Greenfoot.getRandomNumber(3); ' , the '3' should be '4'; otherwise 3 will never be returned. The return range of 'getRandomNumber(n)' is 0 to n - 1.

Thanks a lot !

The '%' operation is 'remainder after division'. 'counter = (counter + 1) % 4;' is equivalent to <Code Omitted>So, on consecutive cycles the value of 'counter' will go 0, 1, 2, 3, 0, 1, 2, 3, 0, 1, 2, etc. Your code with the 'while' statement will not work in the manner you would want. Certainly, line 5 will always return false.

My last post was in reference to my post previous to that.

Ok, sorry for the mistake.

Thank you nccb, it worked :)

@nerdlemon888, see this post in another discussion.

As I said before, we probably need to see the complete code.

A method like that would probably take up way too much CPU time and slow down your scenario. Also, it would be a very complicated method to write. It would be even more complicated if the color could be from another actor as well as from the world. I was thinking about creating actors for each possible point that could be found; but, even that would require a multitude of transparent pixel-sized actors. These actors, however, could be rotated to indicate the slope of the edge at that point (I noticed you were looking at the 'Gravity Engine' scenario). You could then use 'getObjectsInRange

Ok, thanks!

Ich hab grad mal ausprobiert Objekte mit removeObjects() zu zerstören. Also bei mir funktionier dieser Code: <Code Omitted> Ich glaube ich kenne den Fehler der dazu führt das das bei dir nicht funktioniert: removeObjects() ist eine methode die in World deklariert ist, was bedeutet das das: <Code Omitted>nur in der world funktionieren wird. Aber das:
