SO I've created a game where my shooter(cat) fires ammo at a dog, but i'm having trouble making that once the ammo hits the dog he would be removed and respawn.
Can anyone help with the code?

Need help on collision detection.
If you click on the menu bar in your scenario, click on import class and import the class animal you will find some methods that will help you with this problem. (found and eat)
If you want your dog to respawn at a random position you have to add this code in your world.
public void act() {
if (getObjects(Dog.class).isEmpty()) {//If your class isn't called Dog you have to use the right classname;
addObject(new Dog(), Greenfoot.getRandomNumber(getWidth()), Greenfoot.getRandomNumber(getHeight());
}
}I dont really want to make it spawn, i firstly want the ammo i have the cat shooting to detect the dog and make him disappear.
public void act()
{
if (Greenfoot.isKeyDown("left"))
{
setRotation (getRotation() - 5);
}
if (Greenfoot.isKeyDown("right"))
{
setRotation (getRotation() + 5);
}
if ("space".equals(Greenfoot.getKey()))
{
fire();
}
}
private void fire()
{
CatAmmo catammo = new CatAmmo();
getWorld().addObject(catammo, getX(), getY());
catammo.setRotation(getRotation());
catammo.move(40.0);
}
}
The Ammo is already working and shooting perfectly i just want it to detect the dog when it hits him
Therefore your need the methods from the class animal like a already said.
public dog(){
public void act()
{
collision();
}
public void collision()
{
CatAmmo c = (CatAmmo) getOneIntersectingObject(CatAmmo.class);
if(c!=null){
setLocation(x,y); //fill in x and y with the respawn point!
}
}
}
You can also add stuff to happen after the if(c!=null) part (under setLocation(x,y).
public void act() << Illegal start of expression .. :/
Can you show us the code you used?
Make sure that you have your () correct. If you don't have enough before the act() method, it will give you that error.
public dog(){
public void act()
this is a method inside a method, which is what is causing the error. I think you meant:
public class Dog {
public void act()
I know why:
public void act() is only recognized if public class Dog extends Actor
do this:
public class Dog extends Actor{
public void act()
{
}
