Currently I'm trying to make a game, in which arrows fall down and the player have to hit the right key in the moment the arrow touches the bar. If the player presses the button to early he loses 1 point. If the player doesn't press anything, he loses a point, because the arrow touches the bottom of the screen.
So far it worked perfectly. But now I added the second player by copying every class and setting new variables --> nothing works....
Would be great if someone could help me fixing this problem.
My World:
One Arrow of Player1:
One arrow of Player2:
public class Pfeil_links2 extends Actor
{
private boolean v = false;
private boolean b = false;
/**
* Act - do whatever the Pfeil_links2 wants to do. This method is called whenever
* the 'Act' or 'Run' button gets pressed in the environment.
*/
public void act()
{
setLocation(getX(), getY()+2);
if (isAtEdge() == true){
((Tanzwelt)getWorld()).Z_null();
if (((Tanzwelt)getWorld()).gibZaehler2().getValue() > 0) {
((Tanzwelt)getWorld()).gibZaehler2().add(-1);
((Tanzwelt)getWorld()).y_minus();
}
getWorld().removeObject(this);
}
else {
PfeilUndLeiste();
}
}
public void PfeilUndLeiste() {
if (isTouching(Leiste.class)) {
v=true;
}
else {
v=false;
}
if ("a".equals(Greenfoot.getKey())){
b=true;
}
else {
b=false;
}
if ( v==true && b==true) {
((Tanzwelt)getWorld()).gibZaehler2().add(1);

}
}
}
