Where do you call it from? (show me)

Getting a random falling shell
fire is called every time you press the mouse
public void fire()
{
Bullet b = new Bullet();
getWorld().addObject(b,getX(),getY());
shell s= new shell();
getWorld().addObject(s,getX(),getY());
s.fall();
b.setRotation(getRotation());
b.move(20);
}
OK (that was not there before). I was just wondering why you would have the shell direct itself to a specific area through random choice; instead of letting it move with some random angle to wherever it ends up.
ive got this
public void fall()
{
int r=Greenfoot.getRandomNumber(60);
setRotation(60+r);
}Adding the following to the Shell class should allow the shells to fall in different directions:
Just change 'move(1);' in your act() method to 'move();'.
// instance variables
double realX, realY;
// method addedToWorld(World world)
public void addedToWorld(World world)
{
realX = (double) getX();
realY = (double) getY();
}
// method move()
public void move()
{
realX += Math.cos(getRotation() * Math.PI / 180);
realY += Math.sin(getRotation() * Math.PI / 180);
setLocation((int) Math.round(realX), (int) Math.round(realY));
}Edited the previous post in this discussion to include the addedToWorld(World world) method.
it doesent fall it goes to the top left of the screen and slowly moves right
see www.greenfoot.org/scenarios/6076
I made those exact changes in my downloaded Fun scenario and they drop in different directions and then follow the bottom edge left or right until a corner is reached (unless it drops straight down to begin with; in which case, it does not move along the bottom edge at all).
I was referring to the falling movement of the shells. That has nothing to do with the possible removal of them.
Did you get the falling of them fixed? or not!
