Lua Example - Collectibles — Love2d Code

Player collects items to increase score.

-- main.lua
local player = {x=200, y=200}
local items = {{x=400, y=200}, {x=500, y=300}}
local score = 0

function love.update(dt)
	for i=#items,1,-1 do
		local item = items[i]
		if math.abs(player.x - item.x) < 25 and math.abs(player.y - item.y) < 25 then
		table.remove(items, i)
		score = score + 10
		end
	end
end

function love.draw()
	love.graphics.rectangle("fill", player.x, player.y, 50, 50)
	for _, item in ipairs(items) do
		love.graphics.circle("fill", item.x, item.y, 20)
	end
	love.graphics.print("Score: " .. score, 100, 50)
end

Love2d Language Guide

LOVE2D (LÖVE) is a free, open-source framework for 2D game development using Lua, focusing on simplicity, rapid prototyping, and cross-platform desktop and mobile deployment.

Primary Use Cases

▸2D game development with Lua
▸Indie game projects
▸Rapid prototypes for game jams
▸Educational programming projects
▸Cross-platform 2D desktop and mobile games

Notable Features

▸Lua scripting for game logic
▸2D graphics rendering
▸Audio and sound effects support
▸Physics module via Box2D
▸Input handling for keyboard, mouse, and gamepads

Origin & Creator

LOVE2D was created by Rafael 'Hoelzro' Lima in 2006, designed to make 2D game development accessible, fast, and flexible with Lua scripting.

Industrial Note

LOVE2D is widely used in indie game jams, rapid prototyping, educational coding projects, and hobbyist 2D game development due to its simplicity and lightweight framework.

Quick Explain

▸LOVE2D uses Lua, a lightweight scripting language, for game logic and rapid development.
▸It provides modules for graphics, audio, physics, input, and file handling.
▸Developers can quickly create 2D games using simple code and minimal setup.
▸LOVE2D is highly extensible with Lua libraries, custom modules, and community tools.
▸It is ideal for hobbyists, indie developers, game jams, and educational projects.

Core Features

▸love.graphics module for 2D rendering
▸love.audio module for music and sound
▸love.physics for Box2D physics
▸love.keyboard, love.mouse, love.joystick for input
▸File system access via love.filesystem

Learning Path

▸Week 1: Lua basics and main.lua
▸Week 2: love.update and love.draw callbacks
▸Week 3: Input handling and collisions
▸Week 4: Physics and audio modules
▸Week 5: Packaging and deployment

Practical Examples

▸2D platformer
▸Top-down shooter
▸Physics-based puzzle game
▸Simple RPG
▸Game jam prototypes

Comparisons

▸LOVE2D vs Unity: LOVE2D is Lua 2D-only and lightweight; Unity is full-featured 2D/3D with C#
▸LOVE2D vs Godot: LOVE2D uses Lua; Godot uses GDScript/C#/VisualScript with editor
▸LOVE2D vs LibGDX: LOVE2D is Lua 2D framework; LibGDX is Java 2D/3D
▸LOVE2D vs Bevy: LOVE2D is Lua 2D-only; Bevy is Rust ECS, 2D/3D code-centric
▸LOVE2D excels in rapid 2D prototyping and small indie games

Strengths

▸Lightweight and easy to learn
▸Rapid development with Lua scripting
▸Cross-platform desktop and mobile support
▸Active community and many tutorials
▸Flexible and extensible via Lua libraries

Limitations

▸Primarily 2D, no native 3D support
▸No built-in GUI system beyond basic drawing
▸Performance depends on Lua scripting
▸Requires external libraries for advanced features
▸Limited IDE support; code editing is external

When NOT to Use

▸Full 3D games
▸AAA-scale projects
▸Complex multiplayer backends
▸Projects needing built-in GUI editors
▸High-performance graphics pipelines

Cheat Sheet

▸main.lua = entry point
▸love.load = initialization
▸love.update(dt) = logic updates
▸love.draw = rendering
▸Modules = love.graphics, love.audio, love.physics

FAQ

▸Is LOVE2D free?
▸Yes, MIT open-source license.
▸Does it support 3D?
▸No, primarily 2D.
▸Can it deploy to web?
▸Web deployment requires third-party tools like Love.js.
▸Is coding required?
▸Yes, Lua scripting is mandatory.
▸Is it beginner-friendly?
▸Yes, lightweight and easy to learn for beginners.

30-Day Skill Plan

▸Build simple 2D games
▸Experiment with physics and input
▸Use Tiled maps and shaders
▸Integrate Lua libraries
▸Publish desktop or mobile builds

Final Summary

▸LOVE2D is a lightweight 2D game framework using Lua.
▸It provides graphics, audio, physics, and input modules.
▸Ideal for rapid prototyping, game jams, and indie development.
▸Cross-platform support includes Windows, macOS, Linux, Android, and iOS.
▸Highly extensible via Lua libraries and community modules.

Project Structure

▸main.lua (entry point)
▸conf.lua (optional configuration)
▸assets/ (images, audio, fonts)
▸libs/ (external Lua libraries)
▸build/ (packaged .love or executables)

Monetization

▸Sell games on itch.io or Steam
▸Integrate ads via external Lua libraries
▸In-app purchases via mobile wrappers
▸License assets and libraries
▸Crowdfunding or donation-based monetization

Productivity Tips

▸Use Lua modules for reusable code
▸Leverage community libraries
▸Test often on target platforms
▸Keep project structure organized
▸Iterate quickly due to lightweight framework

Basic Concepts

▸love.load(): initialization function
▸love.update(dt): called each frame for logic updates
▸love.draw(): called each frame for rendering
▸love.keypressed / love.mousepressed: input events
▸Modules like love.graphics and love.physics handle functionality
