I am working on the scenario Asteroids and what my objective is presently is to create a counter separate from the points counter which I have running smoothly to count down from 5 and once the counter is 0 proton wave can no longer be used. Each time it runs however, when I press control, it counts down once from 5 to -5 and it counts down for as long at control is pressed. Here is what I have that is connected to this.
Rocket Class
private int down = 5;
private void checkKeys()
{
if(Greenfoot.isKeyDown("control") && down <= 5)
{
startProtonWave();
down--;
space.minusWave();
}
}public class pCounter extends Actor
{
private static final Color textColor = new Color(255, 180, 150);
private int value = 0;
public int target = 5;
private String text;
private int stringLength;
/**
*
*/
public pCounter()
{
this("");
}
/**
*
*/
public pCounter(String prefix)
{
text = prefix;
stringLength = (text.length() + 2) * 10;
setImage(new GreenfootImage(stringLength, 16));
GreenfootImage image = getImage();
image.setColor(textColor);
updateImage();
}
/**
*
*/
public void act()
{
if(value < target)
{
value++;
updateImage();
}
else if(value > target)
{
value--;
updateImage();
}
}
/**
*
*/
public void add(int score)
{
target += score;
}
/**
*
*/
public int getValue()
{
return value;
}
/**
* Make the image
*/
private void updateImage()
{
GreenfootImage image = getImage();
image.clear();
image.drawString(text + value, 1, 12);
}
}Space Class
public void minusWave()
{
pWave.add(-1);
}
