Hello,
I want to make a top-down shooter with boxes you can push around in Godot 4.
But the Character Body 2D can’t push my box and just stops.
I use the move and slide function.
And my RigidBody2D is not static, gravity still works.

Thank you for your answer!

Hi, I’m not quite sure, but it looks like the CharacterBody2D can’t move RigidBodys on its own.

You can do it manually, here is an example:

var force = 1000

if $CharacterBody2D.move_and_slide(): # true if collided
	for i in $CharacterBody2D.get_slide_collision_count():
		var col = $CharacterBody2D.get_slide_collision(i)
		if col.get_collider() is RigidBody2D:
			col.get_collider().apply_force(col.get_normal() * -force)

Thx for this! After I learnt enough GDScript to implement, worked perfectly. In case anyone else is as n00b as me, I added a new node under my CharacterController2D (my top level) called “Pusher” and added this as a script:

extends Node2D

@export var pushForce = 500

@export var bodyPath: NodePath = ".."

@onready var body: CharacterBody2D = get_node(bodyPath)

func _physics_process(_delta):
	if body.move_and_slide(): # true if collided
		for i in body.get_slide_collision_count():
			var col = body.get_slide_collision(i)
			if col.get_collider() is RigidBody2D:
				col.get_collider().apply_force(col.get_normal() * -pushForce)

HTH :slight_smile:
