Hero: Run

Part of the Input and Movement section of Coddy's Godot journey. Lesson 23 of 28.

Over the next lessons you build a platformer hero, one step at a time. Each lesson adds to the script from the lesson before. The level has ground, a pit, a step and a high ledge with a flag.

The hero is a CharacterBody2D with a CollisionShape2D and a Look node for its drawing. The ground, the step and the ledge are StaticBody2D nodes.

Start with gravity and running:

velocity.y += gravity * delta
velocity.x = Input.get_axis("move_left", "move_right") * speed
move_and_slide()

Run right into the pit and the hero falls out of the level. Later lessons fix that.

Challenge

Easy

In _physics_process, make the hero fall with gravity, run left and right at speed, and move with move_and_slide().

Try it yourself

extends CharacterBody2D

var speed = 220
var gravity = 1000

func _physics_process(delta):
	pass

Test yourself

This lesson includes a short quiz. Start the lesson to answer it and track your progress.
