Flap the Flyer

Part of the Projects section of Coddy's Godot journey. Lesson 20 of 33.

Space makes the flyer flap. A flap sets the speed to a fixed upward value, so every flap feels the same.

if Input.is_action_just_pressed("jump"):
	velocity.y = FLAP

With FLAP at -300, the flyer goes up, slows down as gravity adds to its speed, then falls.

Use is_action_just_pressed, so one press is one flap. Put the flap between the gravity line and the move line. Then the move uses the new speed in the same frame.

Challenge

Medium

Add const FLAP = -300. When jump is just pressed, set velocity.y to FLAP.

Try it yourself

extends CharacterBody2D

const GRAVITY = 900

func _physics_process(delta):
	velocity.y += GRAVITY * delta
	position += velocity * delta
