Journal: A CRUD developer builds a game
What did I do today? #
I got some stuff to move on the screen, so that's cool. I borrowed some art from the internet, so that made it easy to get something on the screen.
What did I learn? #
I'm starting to understand that system of nodes and signals in Godot. I think it will be pretty powerful once I get better thinking in that mindset.
Some things I learned today:
- The engine makes things like collision detection and movement pretty easy
- Godot 4 is not ready if you hope to publish to Web (like the demo below)
- I had to restart the project in Godot 3.5 to be able to publish something that works in the browser
Here is some code I wrote today to control the player:
extends Area2D
export var speed = 400 # How fast the player will move (pixels/sec).
var screen_size # Size of the game window.
export var rotation_speed = 5
func _ready():
screen_size = get_viewport_rect().size
position = screen_size / 2
rotation = PI / 2
# Called every frame. 'delta' is the elapsed time since the previous frame.
func _process(delta):
var rotation_dir = 0
if Input.is_action_pressed("turn_left"):
rotation_dir -= 1
if Input.is_action_pressed("turn_right"):
rotation_dir += 1
rotation += rotation_dir * rotation_speed * delta
var move_direction = 0
if Input.is_action_pressed("move_forward"):
move_direction -= 1
if Input.is_action_pressed("move_backward"):
move_direction += 1
var velocity = Vector2(move_direction, 0).rotated(rotation).normalized() * speed * delta
position += velocity
# if the player fully moves outside the screen, wrap around
if position.x > screen_size.x:
position.x = 0
elif position.x < 0:
position.x = screen_size.x
if position.y > screen_size.y:
position.y = 0
elif position.y < 0:
position.y = screen_size.yDemo #
