HELP PLEASE!
Well, resetting the counter to 0 is easy (if it's an int like I think you're talking about)
But you need to tell it to do that when it reaches the base camp. Is your base camp an actor, or a new world?
I'm going to assume it's an actor.
You can use the getOneIntersectingObject() method for Actor to see if specific actors are intersecting the actor that calls the method. It will return an actor, or null, if no actor intersects this one. So you can use the method like this:
Hope that helped!
counter = 0;
if (getOneInetersectingObject(BaseCamp.class) != null) //In other words, if a BaseCamp object is interesecting this, and exists
{
counter = 0;
}Mez what's this counter called? is it your second one? and post the code from this counter pls
Also I need your code for the picking up passengers and then increasing the counter when you pick a person up

first is counter code second is robot
what does the
do???
public void scorer()
{
world worldWorld =(world) getWorld();
Counter counter = worldWorld.getCounter();
counter.bumpCount(-1);
}its for the fuel counter it reduces it by one
Ok in your robot create a class next as so:
first create two variables called passengerscarrying=0; and passengersleft=4; at teh very start. Then when you pick up a passenger add - passengerscarrying=passengerscarrying+1;
Here is the code to go below scorer():
public void atbasecamp(){
locationytwo =getY();
locationxtwo =getX();
if(locationxtwo==6&&locationytwo==3) {
while(passengerscarrying>0){
world worldWorld = (world) getWorld();
//need to call your counter like you do in line 4 of the post above
counter1.add(-1);
passengersleft=passengersleft-1;
passengerscarrying=passengerscarrying-1;
}
//send to where you want it to go next
}

Yes? Sorry for late response.
my counter is a actor not an int variable
You can change the values in the int, can't you? If not, make a variable to change it.
