Click on game object

I too need to be able to click a game object. Its essential for my game.

In the GUI you can do this:

` if action_id == input_touch and action.pressed then
local circle = go.get_id()

 	if go.pick_node(btn, action.x, action.y) then
	print("I'm clicked")
	end
 
 end`

How can it not exist a similar function for game objects or sprites?
