Hi, Im having a mess with arraylist. I´ve made an skech wich consist in a wheel whith some hooks in wich you can hung some weights. So when you push a button, the wheel start to round depending on the weights you hang.
It works, but I tried to put a restart button. So when you push, the weights arraylist is suposed to be erased, but its strange because only some weights are erasen, not all. The code that erase the weights is at the end.
This is the complete code:
class Pesa{ //weight
float masa;
int enganche;
float brazo;
float angle;
Pesa(int enganche0, float angle0, float masa0){
enganche = enganche0;
masa = masa0;
angle = angle0;
}
}
class Enganche{ //hook
float x;
float y;
Enganche(int x0, int y0){
x = x0;
y = y0;
}
}
Enganche[] enganches = new Enganche[9];
ArrayList pesas= new ArrayList();
