In this on-rails shoot-em-up demo, the player gets to control a Space ship flying through a 2D version of Space, while firing their lasers by hitting the Space bar. Various enemies will enter the screen from the right and try their hardest to destroy the player's ship. Shooting these enemies will award points and the highest score achieved is kept in a one-entry leaderboard. Avoiding the blocky obstacles and the enemies is key to survival and high scores, so good luck and have fun!

Controls

WSAD or Arrow Keys to move the ship
Space to fire lasers

Godot Concepts presented in the demo

Editor Workflow

Importing assets (images, sounds)
Using Scenes to group Nodes into small, mostly self-contained units of functionality
Using a TileMap and TileSet to place obstacles in the level
Use of AnimationPlayer nodes to both animate properties (position, rotation) as well as trigger functions
Using a Parallax Background to give an impression of speed and distance traveled

Scripting

Using signals to communicate between Nodes that are created in different Scenes
Using groups to tag and identify Nodes
Interactions between KinematicBody2D and Area2D nodes for hit detection / collision
Use of VisibilityNotifier2D to remove Nodes that move off screen
Dynamically instancing loaded Scenes as Nodes

GUI

GUI Containers for organization and positioning
GUI Controls to start and stop gameplay
Use of a CanvasLayer to keep GUI always on top of the gameplay screen

Miscellaneous

Persisting a "savegame" in the user directory for the highscore

Interactivity

Player input for movement and firing
