Walls Stop You

Part of the Input and Movement section of Coddy's Godot journey. Lesson 9 of 28.

The walls and the pillar are StaticBody2D nodes. A static body never moves. Each has a CollisionShape2D for its solid shape and a ColorRect to draw it.

Only move_and_slide() checks for walls. Changing position moves the body without checking, so it goes through walls:

position.x += direction * speed * delta   # through walls
velocity.x = direction * speed            # stopped by walls
move_and_slide()

Text after # is a comment. Godot skips it.

A body that hits a wall at an angle keeps the part of its movement along the wall. It slides instead of sticking, which gives move_and_slide() its name.

Challenge

Easy

This hero walks through the pillar and the walls. Move it with velocity and move_and_slide() so the walls stop it.

Try it yourself

extends CharacterBody2D

var speed = 200

func _physics_process(delta):
	var direction = Input.get_axis("move_left", "move_right")
	position.x += direction * speed * delta
