Hey, how do I spawn 2 Objects in 2 different sizes?
I have one square which has to be 50x50 and the other one is random between 30 and 50, but I dont know how to give them different sizes.

{
setMyImage();

}
private void setMyImage()
{
GreenfootImage img = new GreenfootImage(100,100);
img.setColor(randomColor());
img.drawRect(0,0,50,50);
setImage(img);
}
private void setMyImage1()
{
int x = 30+Greenfoot.getRandomNumber(50)+1;
GreenfootImage img = new GreenfootImage(100,100);
img.setColor(randomColor());
img.drawRect(0,0,x,x);
setImage(img);
}
public void act()
{
}
private Color randomColor(){
int red = Greenfoot.getRandomNumber(256);
int green = Greenfoot.getRandomNumber(256);
int blue = Greenfoot.getRandomNumber(256);
return new Color(red, green, blue );
}
The constructor will need to know whether to create a fixed sized or a random sized square. A boolean parameter will do the trick:
Then in world use new Square(false) to create a 50x50 square and use new Square(true) to create a random sized one.
Your random size is currently set to between 31 and 80. For between 30 and 50, inclusive, use:
1 2 3 4 | public Square(boolean randomSized){ if (randomSized) getMyImage1(); else getMyImage();} |
1 | int x = 30+Greenfoot.getRandomNumber(20+1); |
public Squares()
{
setMyImage();
setMyImage1();
}
private void setMyImage()
{
GreenfootImage img = new GreenfootImage(100,100);
img.setColor(randomColor());
img.drawRect(0,0,50,50);
setImage(img);
}
private void setMyImage1()
{
int x = 30+Greenfoot.getRandomNumber(50)+1;
GreenfootImage img = new GreenfootImage(100,100);
img.setColor(randomColor());
img.drawRect(0,0,x,x);
setImage(img);
}
public void act()
{
}
private Color randomColor(){
int red = Greenfoot.getRandomNumber(256);
int green = Greenfoot.getRandomNumber(256);
int blue = Greenfoot.getRandomNumber(256);
return new Color(red, green, blue );
}
public Squares(boolean randomSized)
{
if (randomSized) setMyImage1(); else setMyImage();
Is this wrong or false? I get now for both a random Size, but one needs to be a fix size
