I am trying to create a simple mp3 player in green foot and use buttons to control the volume. I have some code that I think should be working but it isnt. Im not sure what the problem is. I am trying to increase the volume bu one when the up button is pushed and decrease the volume by 1 when the down button is pushed I am fairly new to programming so any help would be great. Thanks!
public class Play extends Actor
{
public GreenfootSound sound = new GreenfootSound("AdventureOfaLifetime.mp3");
private boolean off = true;
int currentVolume = sound.getVolume();
Up volumeUp;
Down volumeDown;
/**
* Act - do whatever the Play wants to do. This method is called whenever
* the 'Act' or 'Run' button gets pressed in the environment.
*/
public void act()
{
if (Greenfoot.mouseClicked(this) && off)
{
setImage("Pause.png");
sound.play();
off = false;
}
else if(Greenfoot.mouseClicked(this) && !off)
{
setImage("Play.png");
sound.pause();
off = true;
}
if(volumeUp.clicked)
{
if(currentVolume < 100)
{
currentVolume = currentVolume + 1;
sound.setVolume(currentVolume);
}
}
if(volumeDown.clicked)
{
if(currentVolume > 0)
{
currentVolume = currentVolume - 1;
sound.setVolume(currentVolume);
}
}
}
public class Down extends Play
{
static boolean clicked = false;
/**
* Act - do whatever the Down wants to do. This method is called whenever
* the 'Act' or 'Run' button gets pressed in the environment.
*/
public void act()
{
if (Greenfoot.mouseClicked(this))
{
clicked = true;
}
else
{
clicked = false;
}
}
public class Up extends Play
{
static boolean clicked = false;
/**
* Act - do whatever the Up wants to do. This method is called whenever
* the 'Act' or 'Run' button gets pressed in the environment.
*/
public void act()
{
if (Greenfoot.mouseClicked(this))
{
clicked = true;
}
else
{
clicked = false;
}
}
