Micro2D: The Code-Only 2D Engine

Micro2D acts as an abstraction layer built on top of Lua Player Plus, featuring an architecture inspired by Unity Engine.

This engine was custom-made for my game Tile Puzzle Ultimate (originally built with Unity), with the goal of offering a Unity-inspired structure and facilitating the port to the Nintendo 3DS.

Below you can see all the modules available in the Micro2D engine:

Modules

bank_fonts	Loads and caches bitmap fonts for the Micro2D engine.
bank_images	Loads and caches images by path, freeing each image after its last release.
bank_sounds	Opens, tracks, and closes sound resources by file path.
components_boxcollider	Axis-aligned box collider attached to a game object.
components_draggable	Makes a game object follow the touch while its box collider is pressed.
components_script	Base component providing script lifecycle hooks.
components_multisprite	Renders a selected cell from a sprite sheet.
components_sprite	Component that renders an image or colored rectangle in world space.
components_transform	Stores a game object's position, rotation, and scale.
components_ui_button	Interactive UI button backed by a BoxCollider.
components_ui_canvas	Canvas that groups UI elements and registers their render tasks on a screen.
components_ui_image	UI component that draws an image or a colored placeholder on a canvas.
components_ui_text	UI component that renders text on a canvas using a bank font.
core_loader	Loads the Micro2D runtime and starts the application.
core_runtime	The runtime module of Micro2D.
debugger	Debugger module for the Micro2D engine.
debugger_enabler	Module for enabling the Micro2D debugger.
debugger_functions	Debugger module containing functions for the Micro2D debugger.
debugger_ui	Debugger UI module for the Micro2D debugger.
gameobject	The GameObject module.
time	The Time module.
systems_collision	Registers colliders and dispatches touch and overlap callbacks.
systems_input_settings	Configures input dead zones and motion-control state.
systems_input	Reads controller state and exposes button, touch, and motion input queries.
systems_rendertask	Defines render tasks with a layer and an execution callback.
systems_renderer	Queues and draws render tasks by screen, coordinate space, and layer.
systems_scenes_scene	Stores a scene's game objects and provides scene lifecycle operations.
systems_scenes	Loads, starts, and unloads configured game scenes.
systems_sound	Provides background music playback through the sound bank.
extender_math	A math extender module for Micro2D.
settings	The module containing the Micro2D engine settings.
