I have a CollisionPolygon2D with a defined shape, but in the “node” area it doesn’t show any signal for collision? It lists:
draw()
hidden()
item_rect_changed()
visibility_changed()
child_entered_tree(node:Node)
child_exiting_tree(node:Node)
ready()
renamed()
tree_entered()
tree_exited()
tree_exiting()
property_list_changed()
script_changed()
However, according to what I was reading in the docs and on other forum posts, it should have area_entered for entering an Area2D, and something else I couldn’t find for colliding with another hitbox.
What’s going on? Can someone help me?

Generally, the signals you’re referring to will belong to the parent of the collision object (an Area2D for example). A typical scene layout might look like:
Area2D
+-- CollisionShape2D
+-- Sprite
The Area2D requires some sort of collision object child to detect collisions, but the signals you’re referring to are on the Area2D node itself.
I have it in a CharacterBody2D, is input_event(viewport:Node, event:InputEvent, shape_idx:int) what I’m looking for? How do I use it?

Ah, with a CharacterBody2D, you should be moving it via move_and_slide() or move_and_collide().
move_and_collid() returns a KinematicCollision2D directly. And, with move_and_slide() you can process collisions via get_slide_collision_count() and get_slide_collision().
I’d recommend you read this docs page thoroughly, as it provides details on collision detection when using a CharacterBody2D.

Thank you! I’d been moving the Node2D that the CharacterBody2D was inside of…
Should I not have it inside of a Node2D?

That sounds like an odd setup. Unless you have a sound reason for doing so (I’d be curious what this is), I probably wouldn’t do that…

I didn’t, so I removed it. I just had the CharacterBody2D inside of a Node2D. No real reason lol.
