Hello, I have 2 actors, actor1 and actor2, when actor1 touches actor2, i want the image of actor2 to change, i did that by writing in the class of actor2: if(isTouching(actor1.class)) { setImage("image"); } but now i want to the equivalent of this code but written in the class of actor1, is that possible? Thanks for reading.

That should not be a problem, provided that you do not make them not touch when found touching to begin with.

If i write that same code in the actor1 class it's the actor1 that's gonna change, but i want the actor2 to change its image. on the class of actor1: if (isTouching(actor2.class) { actor2.setImage("image"); // i need the equivalent of this statement if its possible }

if (isTouching(actor2.class)) {
    Actor a2 = getOneIntersectingObject(actor2.class);
    a2.setImage("image");
}

or

if (isTouching(actor2.class)) getOneIntersectingObject(actor2.class).setImage("image");

or

Actor a2 = getOneIntersectingObject(actor2.class);
if (a2 != null) a2.setImage("image");

The last way is probably best as only one time is intersection checked, there.
