What it does

Love2d Core is an agent skill from gamedev-skills/awesome-gamedev-agent-skills. Structure and debug a LÖVE (Love2D) game in Lua: the love.load/update/draw loop, delta-time movement, input, and screen states. Use when building a LÖVE 11.x game (main.lua, conf.lua, .love).

Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/state-stack.md`).

It sits in Game Development. It works with Lua. The repository describes itself as: 74 game-dev skills for AI coding agents — Godot, Unity, Unreal, Phaser, PixiJS, three.js, Bevy, pygame, LÖVE, Roblox. Portable SKILL.md Agent Skills (the format Anthropic… The licence is Apache-2.0.

When your agent uses it

  • Building a LÖVE 11.x game (main.lua

Example prompts

  • “/love2d-core”

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. main.lua skeleton (the callback loop + input)
  2. Frame-rate independence (the single most common bug)
  3. conf.lua (window + version; runs before main.lua)
  4. Color is 0–1 in LÖVE 11.x (not 0–255)
  5. Screen states (brief — full manager in references)

What it can do on your machine

Read from SKILL.md and the folder at commit 0a70cfc. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are lua).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Love2d Core loads about 1.6k tokens when it runs, and up to ~2.7k if it reads all its reference files. Until then it costs about 51 tokens; SKILL.md has 417 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~51
When it runs · the whole SKILL.md, loaded when a task matches
~1.6k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.7k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Structure and debug a LÖVE (Love2D) game in Lua: the love.load/update/draw loop, delta-time movement, input, and screen states. Use when building a LÖVE 11.x game (main.lua, conf.lua, .love).

LÖVE (Love2D) Core

Set up and debug the foundation of a LÖVE game in Lua: the callback loop, frame-rate- independent movement, input, and screen states. Targets LÖVE 11.5.

When to use

  • Use when starting a LÖVE game, wiring up main.lua/conf.lua, or fixing the core loop, movement that runs at the wrong speed, input handling, or screen switching.
  • Use when the workspace has main.lua calling love.*, a conf.lua, or a .love file.

When not to use: Lua language questions unrelated to LÖVE; physics bodies/joints (LÖVE uses Box2D via love.physics — a separate concern); shader code (love.graphics GLSL is its own topic). For cross-engine save/load patterns, use save-systems.

Core workflow

  1. Confirm the entry points. A LÖVE game runs main.lua; it should define love.load() (one-time setup), love.update(dt) (state), and love.draw() (rendering). Window/version setup goes in conf.lua (run before modules load).
  2. Pin the version. Set t.version = "11.5" in conf.lua so LÖVE warns on mismatch.
  3. Drive all motion by dt (delta time, in seconds) so speed is frame-rate independent.
  4. Handle input two ways: polled (love.keyboard.isDown in update, for held keys) and event (love.keypressed callback, for discrete presses).
  5. Manage screens (menu, game, pause) with a small state stack rather than a pile of if flags — see Patterns and references/state-stack.md.
  6. Run and observe. Launch with love . from the project folder; verify the window, motion speed, and input on screen before assuming it works.

Patterns

1. main.lua skeleton (the callback loop + input)
lua
-- main.lua — LÖVE calls these callbacks for you. Colors are 0–1 in LÖVE 11.x.
function love.load()
    -- One-time setup. speed is in PIXELS PER SECOND, not per frame.
    player = { x = 100, y = 100, size = 40, speed = 220 }
    love.graphics.setBackgroundColor(0.1, 0.1, 0.12)
end

function love.update(dt)
    -- Polled input: good for continuous movement while a key is held.
    if love.keyboard.isDown("right") then player.x = player.x + player.speed * dt end
    if love.keyboard.isDown("left")  then player.x = player.x - player.speed * dt end
    if love.keyboard.isDown("down")  then player.y = player.y + player.speed * dt end
    if love.keyboard.isDown("up")    then player.y = player.y - player.speed * dt end
end

function love.draw()
    love.graphics.setColor(0.2, 0.8, 1.0)                 -- tint ON
    love.graphics.rectangle("fill", player.x, player.y, player.size, player.size)
    love.graphics.setColor(1, 1, 1)                       -- reset tint before text/images
    love.graphics.print("Arrow keys to move, Esc to quit", 10, 10)
end

function love.keypressed(key)
    -- Event input: fires once per physical press. Use for menus, jumps, toggles.
    if key == "escape" then love.event.quit() end
end
2. Frame-rate independence (the single most common bug)
lua
-- RIGHT: scaled by dt → same real-world speed at 30 or 240 FPS.
player.x = player.x + player.speed * dt
-- WRONG: "pixels per frame" → moves twice as fast at double the frame rate.
player.x = player.x + player.speed
Show full SKILL.md (170 more words)Show less
3. conf.lua (window + version; runs before main.lua)
lua
-- conf.lua — must be its own file; love.conf will NOT run from main.lua.
function love.conf(t)
    t.version = "11.5"             -- the LÖVE version this game targets (string "X.Y")
    t.window.title  = "My LÖVE Game"
    t.window.width  = 800
    t.window.height = 600
    t.window.vsync  = 1            -- number since 11.0: 1 = on, 0 = off, -1 = adaptive
    t.window.resizable = false
    t.modules.physics = false      -- disable modules you don't use to trim startup/memory
end
4. Color is 0–1 in LÖVE 11.x (not 0–255)
lua
-- LÖVE 11.x uses normalized floats. (Pre-11.0 code used 0–255 and will look wrong.)
love.graphics.setColor(1, 0, 0)                          -- opaque red
love.graphics.setColor(0.2, 0.8, 1.0, 0.5)               -- translucent cyan (alpha 0.5)
-- Need to convert old byte values? Use the helper instead of dividing by hand:
love.graphics.setColor(love.math.colorFromBytes(128, 234, 255))
5. Screen states (brief — full manager in references)
lua
-- A screen is a table with optional :update(dt), :draw(), :keypressed(key).
-- Keep the active screen on a stack so pause/menu overlays are trivial to pop.
local Stack = require("state_stack")   -- see references/state-stack.md for the module
function love.load()              Stack.push(require("screens.menu")) end
function love.update(dt)          Stack.current():update(dt) end
function love.draw()              Stack.current():draw() end
function love.keypressed(key)     Stack.current():keypressed(key) end

Pitfalls

  • Speed varies with FPS → you forgot * dt. Every per-frame change to position, timers, or animation must be scaled by dt.
  • love.conf placed in main.lua → it silently does nothing. It must live in conf.lua, which LÖVE runs before loading modules.
  • Colors washed out or invisible → you used 0–255 values. In 11.x, setColor(255,0,0) clamps to white; use setColor(1,0,0) or love.math.colorFromBytes.
  • Everything tinted after one setColor → color is global and persists across draws. Reset with love.graphics.setColor(1, 1, 1) before drawing text/images you want untinted.
  • Nothing happens on key release/repeat → love.keypressed(key, scancode, isrepeat) fires on press (and OS key-repeat); use love.keyreleased for release, and check isrepeat if you must ignore held-key repeats.

References

  • For a complete push/pop screen-state manager (menu → game → pause, with delegated callbacks), read references/state-stack.md.
  • save-systems — saving/loading game state (engine-agnostic).
  • input-systems — rebindable, multi-device input architecture.
  • pygame-core / phaser-core — the same loop concepts in other lightweight engines.
