I would like to make 2 forms of gold income, one by gaining a certain amount of gold my pressing spacebar(gold/action) and the other one is gaining gold at a steady pace(gold/min). anyone has any idea how to do that?

Gold Income
I hope this code works
You should just be able to put this method right in the act()
Also when getting upgrades, you can just change the moneyPerAct and moneyPerMin values no prob
I made this on my phone but i hope it helps.
Also, the preciseGold value is used so that i could make it increase smoothly overtime. The gold value is just for displaying purposes, hence why it is rounded to int
private float preciseGold = 0;
public int gold = 0;
private boolean once = false;
private int moneyPerMin = 80;
private int moneyPerAct = 10;
private void gainMoney() {
if(Greenfoot.isKeyDown("space") && !once) {
preciseGold += moneyPerAct;
once = true;
} else if(!Greenfoot.isKeyDown("space) && once) once = false;
// assuming greenfoot's speed is 50
// if you want to make sure it stays at 50, uncomment the next line
// Greenfoot.setSpeed(50);
preciseGold += moneyPerMin / 60f / 50;
gold = (int) preciseGold;
// When buying something, only subtract the price from preciseGold!
}I'm using a code to display the gold(Yen):
but it seems to be stuck at 0 no matter how many times I pressed/held space am I doing something wrong??
PS: what is 60f?
GreenfootImage image = new GreenfootImage("Yen: " + DYen, 20, Color.BLACK, Color.WHITE);
setImage(image);

The number '60' as a 'float' type value.Lavenger wrote...

preciseGold += moneyPerMin / 60f / 50;
gold = (int) preciseGold;
}
}Here's what I did:
I have placed the Yen display into another actor:
import greenfoot.*;
public class Umaru extends Actor
{
public void act()
{
GainYen();
}
public int DYen = 0;
private float AYen = 0;
private boolean HoldSpaceBuff = false;
private int YenPerMin = 90;
private int YenPerAct = 1;
public void GainYen()
{
if(Greenfoot.isKeyDown("space") && !HoldSpaceBuff)
{
AYen += YenPerAct;
HoldSpaceBuff = true;
}
else if(!Greenfoot.isKeyDown("space") && HoldSpaceBuff)
{
HoldSpaceBuff = false;
Greenfoot.setSpeed(50);
AYen += YenPerMin / 60f / 50;
}
DYen = (int) AYen;
// When buying something, only subtract the price from AGold!
}
}import greenfoot.*;
public class Gold extends Actor
{
public int DYen = 0;
public void act()
{
GreenfootImage image = new GreenfootImage("Yen: " + DYen, 20, Color.BLACK, Color.WHITE);
setImage(image);
}
}
Both are using a different variable. It has the same name but that doesn't mean that it is the same.

You don't link the two variables. You will only use one variable. The Umaru object could have a reference to the Gold object and then, the Umaru object can control the Gold object (when the variable changes, the Umaru object tells the Gold object to change its image).

The Umaru object could have a reference to the Gold object and then, the Umaru object can control the Gold object (when the variable changes, the Umaru object tells the Gold object to change its image).Are they created from the same "position" in your code, for example right at the beginning?
You could do that then:
Gold g = new Gold(); addObject(g, /**x-coord, y-coord*/); addObject(new Umaru(g), /**x-coord, y-coord*/);
//Gold class
public void updateImage(int yen)
{
setImage(new GreenfootImage("Yen: " + yen, 20, Color.BLACK, Color.WHITE));
}//in Umaru class
private Gold gold;
public Umaru(Gold g)
{
gold = g;
}
//after a change to DYen was made:
gold.updateImage(DYen);If you want to get the DYen from the Umaru object, you could make a constructor for the Gold class that needs an Umaru object, like thisThen in the Umaru class, you can add the addedToWorld() method that greenfoot calls automatically. In that method you can create a Gold object that is 'linked' with the Umaru.
The method should look something like this:
private Umaru umaru = null;
public Gold(Umaru umaru) {
this.umaru = umaru;
}public void addedToWorld(World world) {
world.addObject(new Gold(this), 100, 100);
