Run and Jump

Part of the Input and Movement section of Coddy's Godot journey. Lesson 15 of 28.

Running changes only velocity.x. Gravity and the jump change only velocity.y. So set the two halves apart:

velocity.x = Input.get_axis("move_left", "move_right") * speed

Do not set the whole velocity, like this:

velocity = Vector2(Input.get_axis("move_left", "move_right") * speed, 0)

That line sets velocity.y to 0 every frame. It erases the falling speed and the jump, so the hero floats.

Challenge

Easy

Let the hero run left and right at speed while it still falls and jumps. Set only velocity.x.

Try it yourself

extends CharacterBody2D

var speed = 220
var gravity = 1000
var jump_velocity = -500

func _physics_process(delta):
	velocity.y += gravity * delta
	if Input.is_action_just_pressed("jump") and is_on_floor():
		velocity.y = jump_velocity
	move_and_slide()
