shoot
I'm assuming you are using if (Greenfoot.isKeyDown(_key_)) ?
Try changing it to the getKey() function, for example:
if ("space".equals(Greenfoot.getKey()))
shoot();
This will check if the space bar is pressed and will shoot a single shot rather than multiple.
solted that out now but it fires 1 shot then if you hold it down it will fire loads of shots a second later. how do you stop that
You're trying to make it shoot only a few times a second? Try this:
Add a variable of type "int" called timeTillCanFire in your player class:
After that, in your "fire()" method, do this:
//the beginning of your class, no changes here...
public class Player
{
//your code should be here....
//at the bottom of your player class, after all of your code, add this:
private int timeTillCanFire;
}public void fire()
{
if(timeTillCanFire == 0) { //if can fire now...
if(Greenfoot.isKeyDown("space")) {
//do whatever you normally do to acually fire.
timeTillCanFire = 10; //wait ten frames before you can fire again.
}
}
if(timeTillCanFire != 0) { //if can't fire now...
timeTillCanFire--; //wait till can
}
