Help Please
Hi guys again. Been working on the code and have a counter and a method in it called bumpcount as shown below
I was wondering if there was a bit of code which would make it so that method would set the counter to zero.
public void bumpCount(int amount)
{
totalCount += amount;
setImage(new GreenfootImage("" + totalCount, 20, Color.WHITE, Color.BLACK));
}
Do you mean this?:
totalCount = 0;
setImage(new GreenfootImage(""+totalCount,20,Color.WHITE,Color.BLACK));Can you check this to see if it would work. When clicked I want it to set the counter (called counter3) to zero.
In the button actor:
and in the counter class
public void setCount(int amount)
{
totalCount = 0;
setImage(new GreenfootImage("" + totalCount, 20, Color.WHITE, Color.BLACK));
}
if (Greenfoot.mouseClicked(this))
{
world worldWorld = (world) getWorld();
Counter3 counter3 = worldWorld.getCounter3();
counter3.setCount(0);
}
Well, to set it to 0 you should use the code you just gave, but change setCount to this again:
public void setCount(int amount)
{
totalCount = amount;
setImage(new GreenfootImage("" + totalCount, 20, Color.WHITE, Color.BLACK));
}Sorry I was wondering what is the code that will read the counter and then store it in an int variable, named choice?
Well, if you're using the same code for the Counter class as shown in your 'Counter help' discussion, add the method I showed you there, and simply do this:
where counter3 is the Counter object you need the value of (I guess that's the name, considering the previous code you showed)
int choise = counter3.getValue();
Okay I presume I need the
world worldWorld = (world) getWorld();
Counter3 counter3 = worldWorld.getCounter3();
before it?
I think the answer to your question above is 'yes' but -
- you've called your world class 'world'? so 'world extends World'? I think you're asking for trouble.
Convention in Java is to begin class names with a capital letter. Use 'MyWorld' or similar.
