Hahaha found my mistake: I accidentally deleted the act() method so I put the method call for addBoids() right below addObject(new Boid).... Changed it and now it works fine! Last question, after that the scenario is completed: I want to set a maximum amount of boids. If this maximum is reached a random number of boids shall be removed. That's my code:

What do you mean directly? You mean diagonally in one straight line? If that's the case can't you just move 1 down and 2 left and repeat that?

Pathfollower and detection of objects

By kartikitrak, with no replies.

Is it possible to make a chain of objects follow a predetermined path in greenfoot and still know that the individual objects in the chain are still seperate objects? For example, random types of orbs come out of no where and link to other orbs to form a chain and this chain follows a path. Luxor Evolved is a good example of this. In the game the orbs are spawned and then follow a path and link up on collision with another orb and then you're supposed to shoot the orbs with the corresponding color orb and when your shot blue orb touches a blue orb that was part of a chain both orbs remove themselves. (That was a lot of orbs) <Image Omitted>

Thinking it through logically, to turn toward the closest pig, this is what needs done: 1) find the closest pig by starting at distance of 1 and incrementing distance until pigs found in range or out of range by this pseudo-code: <Code Omitted> 2) upon exiting the loop, pigs in range List will either be empty or ... not; close with this pseudo-code:

Help for mouse.

By h123n, with 4 replies.
Last reply by danpost, almost 13 years ago:

You need an instance boolean variable (or field) to track 'mouse pressed on me, and not yet released' or 'dragging'. Set it to 'true' if mouse pressed on this object. Set it to 'false' if the mouse is clicked (released) anywhere (use 'null' as parameter). Write an 'if' block to follow the mouse (SPower's code, but using 'if (dragging && Greenfoot.mouseMoved(null)) {' in line 1).
