Hey! I am wondering how I do two things.
1. How do I detect if Actor A is touching Actor B?
2. How do I make it so when "Reset" is pressed Actor A and B show.
Thanks.

Loading in Actors and If touching Actor
1. There are several ways to detect another object.
getOneIntersectingObject(java.lang.Class cls)
getOneObjectAtOffset(int dx, int dy, java.lang.Class cls)
You'd write it like...
or have have a look at Greenfoot class documentation..
2. Place the objects into your world --> right click with your mouse --> safe the world
Actor actor = getOneIntersectingObject(null); // place the class you want to check for, instead of null write "yourclass.class" without "".
if (actor != null){
place some code
} else {
place some more code
}
1.
in class A
2.
Either do it with the safe-the-world feature as described in the last post, or you do it manually.
In the world constructor (so after the 'super' call):
Adjust the values to your needs.
if (isTouching(B.class))
{
//do something
}addObject(new A(), 20, 10); addObject(new B(), 30, 50);
There is also an Actor class method 'intersects(Actor)' which you can use if you have a reference to the actor you are checking the intersection of.
/// in ActorA class
private Actor actorB; // as instance field set to the actor to intersect with
// in act
if (intersects(actorB)) { ... }You need to login to post a reply.
