#
I have my actor trying to "eat" its gold and the score adds to one, but its not working. please help me!!!! very urgent. /** * Act - do whatever the Crosser wants to do. This method is called whenever * the 'Act' or 'Run' button gets pressed in the environment. */ public void act() { eat(); } } public void eat() { Actor gold; gold = getOneIntersectingObject(Gold.class); if (gold != null) { World myWorld = getWorld(); myWorld.removeObject(gold); RoadWorld RoadWorld = (RoadWorld)myWorld; Counters Counters = RoadWorld.getCounters(); Counters.addScore(); RoadWorld.removeObject(this); } } The problems are occuring on my actor crosser. My counter world class has no problem.

It the problem that when you eat gold the actor disappears as well?

#
In the middle of the 'if' block, you are declaring a variable, 'RoadWorld', with the exact name of the class. This is probably confusing the compiler. Change the name of the variable to 'roadWorld' (with a small 'r') and use it throughout the rest of the block.

#
That last line: 
roadWorld.removeObject(this);
will do that. Remove it.

#
@danpost great!!!!!! it works but then how do i get the score counter to move everytime it eats the gold. my counter class public class Counters extends Actor { int score = 0; /** * Act - do whatever the Counter wants to do. This method is called whenever * the 'Act' or 'Run' button gets pressed in the environment. */ public void act() { setImage(new GreenfootImage("Score ; " + score, 24, Color.BLUE, Color.BLACK)); } public void addScore() { score++; } }

#
Are you getting any error messages? or is the counter just not showing any changes in score?

#
Make sure the score object in the world is the same one that you have referenced in your world class. If you are unsure what I mean, post your world class code.

#
@danpost thats all i put. i followed thru a youtube video by jim stewart public Counters getCounters() { return counters; }
danpost danpost

#
You should have the 'counters' field declared in the world class; plus, you should have the Counters object being created and added into the world somewhere in the world class. Again, maybe you should post your world class code. Oh, and please use the 'code' link below the 'Post a reply' content box to insert your code into your post.
