How can I use Actor.hit for collision detection?

Question

How can I use Actor.hit in libgdx . I want to know when two Actors collide through animation, is the Actor.hit method what I would use?

Please read the documentation: here

Hit is used for user input only, like touch and mouseevents. It is not how you detect collisions.

You would need to do that yourself with a Rectangle for example which you update like this:

private void updateBounds() {
    bounds.set(getX(), getY(), getWidth(), getHeight());
}

Then you can easily check for collisions/overlaps with other Actors.

@noone what if i have a single actor and it is circle , how can i detect touch only for the circular image. – ManishSB Aug 13 '14 at 04:43
then you need to override the hit method. How to check if the coordinate is in the circle: http://stackoverflow.com/questions/481144/equation-for-testing-if-a-point-is-inside-a-circle – noone Aug 13 '14 at 05:07
