I use your Zombie Shooter Demo so i would like to request just help...
I look for when a player arrives at the score of 50 or 100 to pass to another world but not with the same "Chased" actor...

@danpost Score switching worlds...
In world act method, add the following line:
if (score > 50 /** or '100' */) Greenfoot.setWorld(/** put new world object here*/);

Thanks !! Also any idea how to make an "Chaser" shoot you?Kokoro wrote...
Nope "cannot find symbol object "Welt_2" not works..ChaserBullet bullet = new ChaserBullet(); // adjust class name as needed bullet.setRotation(getRotation()); getWorld().addObject(bullet, getX(), getY());
I'm lost... like i just want to make it shoot tell me in which class "QActor" or Chaser?
Also the world change cannot be done with that score function .. "if (score > 50 /** or '100' */) Greenfoot.setWorld(/** put new world object here*/);"
Well i managed to fix the world teleportation by score...
Still i need help with an actor that shoots you and also i need help with the "Scoreboard" that thing in left well it needs a white element that shows the score any way to fix ? I'm sure is in Welt > at public class or more..
The code for the chasers to fire bullets goes in the act method of the Chaser class. The change world code, after inserting the new world object where indicated, would go in the act method of the class of the currently active world.

Ok i will try also thanks for the support sir !!Kokoro wrote...
I'm dumb explain me step by step... :(So to restart it over teleport by the score is fine...
Well about an actor shoots you...
import greenfoot.*;
public class Chaser extends QActor
{
int dr = 0; // the current turn rate
public Chaser()
{
setBoundedAction(Welt.actionType, Welt.actionDistance); // set bound fields
// create image for this actor
GreenfootImage image = new GreenfootImage(30, 30);
image.fillOval(0, 0, 30, 30);
image.setColor(new java.awt.Color(224, 240, 255));
image.fillOval(7, 7, 16, 16);
setImage(image);
}
/**
* turn and move actor
*/
public void act()
{
int dx = 0, dy = 0; // the differences in locational coordinates
int rate = 0; // the rate of turn and speed
Actor chased = Welt.chased;
if (chased != null && chased.getWorld() != null)
{ // set variable values
dx = getX()-chased.getX();
dy = getY()-chased.getY();
rate = 400-(int)Math.abs(dx)-(int)Math.abs(dy);
}
if (rate > 100)
{ // chase
// the next code line does what is described in the following commented lines
// determine shortest turn direction to face chased
// int angleDiff = getRotation()-(int)(Math.atan2(dy, dx)*180/Math.PI); // range: -359 to 359
// int anglet = (angleDiff+360+180)%360-180; // range: -180 to 179 (sign is turn direction)
// turn and move
// turn(16*rate*(int)Math.signum(anglet));
turn(16*rate*(int)Math.signum((getRotation()-(int)(Math.atan2(dy, dx)*180/Math.PI)+540)%360-180));
move(rate/8, getQR()); // between 'move(0.1)' to 'move(0.4)' for a non-QActor, which is not possible
}
else
{ // wander
// vary turn rate
dr += 2-Greenfoot.getRandomNumber(5)-(int)Math.signum(dr);
// limit turn rate to between 40 q-rotation units left and right
if (dr < -40) dr = -40;
if (dr > 40) dr = 40;
// turn and move
turn(dr);
move(10);
}
}
}
