Button component on sprite object

Hi, i am making a 2D game. I want to add "Button" component to sprite object in world, so i can use it as a button. I want to use the component's "OnClick" function instead of Raycasting or OnMouseDown functions.
"OnClick" will make it much more easier for me.
So i tried to add Button component, but it didn't work. I tried to add Box collider but nothing changed. Is it possible to use "Button" compoenent outside of GUI?
If so, what should i do? If not, is there a way that i can use "OnClick" function, in my gameboject? Or, do i have to use RayCasting or OnMouseDown function to use my sprite as a button?
-Thank you^^

 

I was reading this just yesterday: http://unitydojo.blogspot.co.uk/2014/08/unity-46-simple-tutorial-new-events.html

Hope that helps you

 

That did work just as i wanted! Thank you really much!!! ^^

 

Very late but I hope I can help someone.
If you add an Image component to your sprite "Object" and then add a Button component, you'll have a button that works properly.

Also, drag the Image component to "Button>Target Graphic" if it's not added already.
+ Add your sprite to the Image component and delete/disable the Sprite Renderer component.

 

Yes you helped me!
Great explanation!

 

I have been pulling my hair out all day trying to figure out what I was doing wrong. I never thought it was an image component I was missing. 2 year later still helping people.

 

I completely forgot, I ever used this forum.
Glad to see I could help someone, though!

 

It wont work for me? nothing happens and i did everything
