I've encountered an issue for when I try to call a sound a play when I shoot a dart. My actor has an if statement to see if the space key is down, and if a counter is above a number. If both are true, the dart spawns and the sound plays, but the problem is that the sound only plays for the first dart and then randomly after that. I've had a similar sound function for when the actor gets hit, and the sound plays even if the there's another hit immediately after so I don't think it has anything to do with the length of the sound.

public void pewSound()
    {
        pew.play();
    }

if (Greenfoot.isKeyDown("space") && DartLimiter > 8 && power==0){
            DartLimiter = 0;//dart spam reset
            pewSound();
            DartThrow fire = new DartThrow();//the actual shooting
            getWorld().addObject(fire, getX() + 3, getY() + 1);//adds the dart
        }

Thanks in advance

It has something to do with your conditions. Remove DartLimiter > 8 and power == 0 out of your if statement and check if the sound plays properly. If that's the case then you are messing up the assigning part.

I am currently using this Method for my SpaceWar game:

private void Shoot()
    {
        if(currentAmmo > 0)
            currentAmmo--;
        getWorld().addObject(new Bullet(getRotation()), getX()+rocketWidth, getY());
        Greenfoot.playSound("/SFX/shoot.wav");
        wait += (currentAmmo > 0) ? reloadtime : reloadtime*multiplier;
    }

The length of the sound may have something to do with it -- particularly if you set the following:

GreenfootSound pew = new GreenfootSound("pew.wav");

This line creates one, and only one, instance of the sound. If you try "pew.play()" while 'pew' is already playing, it does not restart or play again. Use:

Greenfoot.playSound("pew.wav");

to play the sound to allow multiple "pew" sounds to play simultaneously. This construct creates a new distinct GreenfootSound object each time it is executed.

Wait, can you still change volume if you do it this way?

Not when using 'playSound'. For multiple sounds where volume is controlled, do not use a field as in the first way above. Instead, create the GreenfootSound object in the code itself when firing the dart:

GreenfootSound pew = new GreenfootSound("pew");
pew.setVolume(50); // or whatever
pew.play();
