Godot, hide objects

Question

Currently the way I do it, is setup an Area2d and a collision shape child for each individual node and then I attach a script to the area2d

extends Area2D

func _input_event(viewport, event, shape_idx):
    if event.type == InputEvent.MOUSE_BUTTON \
    and event.button_index == BUTTON_LEFT \
    and event.pressed:
        sorite.hide()

Is there a faster way? suppose I want to hide each object the user clicks on, and only then I want to allow him to press on SpriteX And I have a trillion object that can be clicked, what to do?

As Charanor stated correctly, you should not worry too much about optimising your code before you actually get into trouble. From my experience the slowest functions are never the ones you would expect :-)

Anyways, Godot offers a nice way to handle inputs using its InputMap. With the InputMap you can define actions and link them to different keys. In the long run it makes it way easier to change keys in the game.

You can find an Introduction to the InputMap in the Pong Tutorial.

For your example I would connect the Area2D-InputEvent Signal (of the Sprite) to your script (using the editor as described here). And then simply add the following code to the generated function.

func _on_Area2D_input_event( viewport, event, shape_idx ):
    if event.is_action_pressed("mouse_left"):
        sorite.hide()

Although I am not sure if it is faster it is way cleaner and as mentioned easier to change later as you just need to change the Key/Button in the inputmap.
