Adding collision to objects

[topaz zealot]

I'm just trying to add collision to my pad (yes, it's pong, I'm too dumb to create other stuff).
But when I do, it warns me with that message in the image.
Is there a way to add that collision shape or an easy-ish way to add collision to an object?

Hi. The collision shape 2D only serves as a shape for a SataticBody, RigidBody or CharacterBody.
What you want is to use either charecterBody or StaticBody node for collision and the collision shape you created as a child of that node. See the documentation: https://docs.godotengine.org/en/4.3/tutorials/physics/physics_introduction.html

I just want basic collisions, that also introduces gravity and stuff I'm def not using

[frozen tangle]

For your application, the characterbody is moody suitable

You can remove the code for gravity by editing the script

I've tried that before, I couldn't change the position stuff

That's why I'm using a node2d

[frozen tangle]

Node 2d doesn't handle collisions

[topaz zealot]

... what

[frozen tangle]

If you want to do anything with collisions, you'll have to use 1 of the nodes mentioned here https://docs.godotengine.org/en/4.3/tutorials/physics/physics_introduction.html

Node 2d is the basic node for all things 2d, it doesn't implement collisions

[topaz zealot]

why can't I add collisions to it though?

[frozen tangle]

That's just how it is; different nodes have different purposes. If you want to use collisions, you need to use a StaticBody, CharecterBody or RigidBody.

[topaz zealot]

okay, then player would be a characterbody (dunno thename), but then the ball, would have no class (it doesn't make sense with any of these)

[frozen tangle]

No, the both the ball and the player would be charecterbody.

You typically use character body for collision objects that are intended to be moved with code.

[topaz zealot]

?

it's a ball, not a character

not controlled by the player either

[frozen tangle]

O sorry, I meant the animatablebody2D node

Since you intend to move it via code

[topaz zealot]

it's not an animation...?

[frozen tangle]

No, its just called that

Because animatable meaning can move

“A 2D physics body that can't be moved by external forces. When moved manually, it affects other bodies in its path.”

https://docs.godotengine.org/en/stable/classes/class_animatablebody2d.html

I'm remembering why I picked love2d for my old stuff, lol

this doesn't make any sense

[topaz zealot]

" 2D physics body that can't be moved by external forces." so I can't change it via code?

and there isn't anything on the docs abt how to move it, since the other collsion(whatever)2d seems to have their own way of moving ( no idea why)

[frozen tangle]

By manually, it means by code.

[frozen tangle]

You move it by adding it position property of the node

[frozen tangle]

Yeah, different ones have their own way of moving: Rigid body is moved by setting forces and impulses, character2d is moved by setting velocity and animatable is moved by changing position

You need to choose which one best suites your application

[topaz zealot]

this kinda looks like a mess, ngl
