A Bullet collides with another Object and the Object dissapears and the Bullet dissapears too so that It doesnt collete more Objects.

You need to implement a hit registration, you can do this the following way
In this instance the bullet is looking if it intersecting with the actor Object. If it isn't intersecting (so it is null or == null), then it returns false. this means that the bullet doesn't despawn when being created. If it is intersecting (so it is not null or != null), then the bullet returns true. This means that the if statement can continue and that the bullet can remove itself. When obj != null, then it will also remove the object it is touching with getWorld().removeObject(obj);
If you want the object to remove itself instead of having the bullet remove the object, then instead of writing "getWorld().removeObject(obj);"
you need to write a code which activates a boolean in the Object.class. Let's call this boolean "Hit", so in Object you put: public boolean Hit = false;
Instead of getWorld().removeObject(obj); you write obj.Hit = true; In the act method of the Object.class you put
Hope this helps and that it works for you :D
1 2 3 4 5 6 | public void act() { if (Remove()) { getWorld().removeObject(this); }} |
1 2 3 4 5 6 7 8 9 | public boolean Remove() { Object obj= (Object)getOneIntersectingObject(Object.class); if(obj != null) { return true; getWorld().removeObject(obj); } return false; } |
1 2 3 4 5 6 7 8 9 10 11 | import greenfoot.*; public class Object extends Actor {public boolean Hit = false;public void act() { if(Hit == true) { getWorld().removeObject(this); Hit = false; }}} |
