Hi, I have a little problem about score over here.
So I have been following steps for making score : https://www.youtube.com/watch?v=VnR6i7BXD-E
but my score counter still doesn't incremented
I think it's because the world is resetted so i can't keep the score, do any of you have solutions?
Here's my code:
"bg" is my world
here's a code for "ular" who eats "hasil" and it supposed to increment the score
here's a code for Counter:
import greenfoot.*;
/**
* Write a description of class bg here.
*
* @author (your name)
* @version (a version number or a date)
*/
public class bg extends World
{
Counter counter = new Counter();
/**
* Constructor for objects of class bg.
*
*/
public bg()
{
// Create a new world with 600x400 cells with a cell size of 1x1 pixels.
super(600, 400, 1);
makanan.reset();
prepare();
}
public Counter getCounter()
{
return counter;
}
/**
* Prepare the world for the start of the program. That is: create the initial
* objects and add them to the world.
*/
