So i want to make a game that requires something (in my case a stone) spawns every five seconds or so (it should also spawn randomly in the map). Is there any possiblity of doing this??
Thanks in advance.

Timer every 5 seconds something spawns
In your active world subclass:
1 2 3 4 5 6 7 8 9 10 | private int stoneSpawn=275, stoneSpawnTimer=stoneSpawn;public void act(){ if (--stoneSpawnTimer==0) { stoneSpawnTimer=stoneSpawn; addObject(new Stone(), Greenfoot.getRandomNumber(getWidth()), Greenfoot.getRandomNumber(getHeight())); }} |
thanks for the reply but unfortunatly its not working... What am i doing wrong?
import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)
import greenfoot.*; // importiert Actor, World, Greenfoot, GreenfootImage
public class GameWorld extends World
{
private int steinSpawn = 275;
private int steinSpawnTimer = steinSpawn;
public GameWorld()
{
super(600, 400, 2);
setBackground("grass.jpg");
//neuen Spieler erstellen
Spieler neuerSpieler = new Spieler();
//neuen Spieler in die Welt setzen
addObject (neuerSpieler, 10, 200);
//es wird jede 5 Sekunden ein neuer Stein hinzugefügt
steinSpawnTimer = steinSpawnTimer -1;
zufälligSteineErstellen();
}
//es wird jede 5 Sekunden ein neuer Stein hinzugefügt
public void zufälligSteineErstellen()
{
if (steinSpawnTimer==0)
{
steinSpawnTimer = steinSpawn;
addObject(new Stein(), Greenfoot.getRandomNumber(getWidth()), Greenfoot.getRandomNumber(getHeight()));
}
}
}
Only the act method is called automatically. The constructor is only executed once when the object is created.
Add this:
And in the method, you forgot the -- in the if condition. Remove the two lines in the constructor. Or instead of the --, you add the first line at the beginning of the method.
Btw, you don't need to import greenfoot twice.
1 2 3 4 | public void act(){ zufälligSteineErstellen();} |
Sorry if im stupid but where should i add that?
Somewhere in the class.
(Btw, I just edited the message if you didn't see it yet.)
OK thanks you very much it works now
