I want to spawn a GreenNote when "o" is pressed, it does that, but it spawns so many that the game freezes. How can I only spawn a single note each time "o" is pressed?
import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)
/**
* @author Calculator
* @version 2
*/
public class GreenNote extends Actor
{
public GreenNote() {
GreenfootImage image = getImage();
image.scale(60,60);
setImage(image);
}
/**
* noteSpeed will make the notes move down quicker.
* noteSpawn2 SHOULD spawn a note upon key press of "o"
*/
public void act()
{
noteSpeed(5);
noteSpawn2();
}
public void noteSpeed(int howFast)
{
setLocation(getX(), getY()+howFast);
}
public void noteSpawn2()
{
GreenNote greennote = new GreenNote();
if(Greenfoot.isKeyDown("o")) {
Greenfoot.delay(1);
getWorld().addObject(greennote, 200, 0);
}
}
}
