Emoticon Project- Gruver- so hard!!!
Your emoticon objects are all using the default image you gave the class to assign them. You either need to assign the image and sound of each emoticon within the 'for' block or pass them to the constructor of the emoticon and have them assigned there.
alright, now how does the for loop do that?
I mean, i have a few ideas; not many make sense.
Wait; how do I get these strings to work?
public class Emoticon extends Actor
{
private String[] sound;
private String[] image;
private void emoticon(String image, String soundFile)
{
setImage( image + ".png");
}
/**
* Act - do whatever the Emoticon wants to do. This method is called whenever
* the 'Act' or 'Run' button gets pressed in the environment.
*/
public void act()
{
// When the mouse is click on this object, play the sound.
if(Greenfoot.mouseClicked(this))
{
Greenfoot.playSound(sound + ".wav");
}
}
}
I may have assigned the different variables in the world with arrays...
can I use those here
(1) you can remove line 4 (once you set the image at line 7, you no longer need that value)
(2) you need to change line 3 to the following (the 'soundFile' argument in the constructor is not an array)
(3) you need to assign the value of 'sound' in the constructor (add this line next to line 7)
Finally, back in your world class, you need to pass the Strings for the image and sound to this constructor by using 'new Emoticon(image, soundfile)'.
private String sound;
sound = soundFile;
/**
* Act - do whatever the Emoticon wants to do. This method is called whenever
* the 'Act' or 'Run' button gets pressed in the environment.
*/
public void act()
{
// When the mouse is click on this object, play the sound.
if(Greenfoot.mouseClicked(this))
{
sound = soundFile;
Greenfoot.playSound(sound + ".wav");
}
} import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)
/**
* Write a description of class Emoticon here.
*
* @author (your name)
* @version (a version number or a date)
*/
public class Emoticon extends Actor
{
private String[] sound;
private String[] image;
private void emoticon(String image, String soundFile)
{
setImage( image + ".png"); sound= soundFile;
}
/**
* Act - do whatever the Emoticon wants to do. This method is called whenever
* the 'Act' or 'Run' button gets pressed in the environment.
*/
public void act()
{
// When the mouse is click on this object, play the sound.
if(Greenfoot.mouseClicked(this))
{
Greenfoot.playSound(sound + ".wav");
}
}
}
