public boolean atMiddleWorld()
{
if(getY()>290&&getY()<300)
{
return true;
}
else
{
return false;
}
}
public void act()
{
setLocation(getX(),getY()+3);
// if(atMiddleWorld()==true)
if(getY()>290&&getY()<300)
{
World W = getWorld();
int y=2;
int x= Greenfoot.getRandomNumber(600);
W.addObject(new masina2(),x,y);
}
if(isTouching(bus.class))
getWorld().removeObject(this);
}
}
and how should i do it combined with the condition checking if it is at the middle of the world?
Your cars only move 3 cells at a time. Limit the spawning to a range of 3. Use:
if (getY() >= 299 && getY() < 302)
