Simple build system for building LÖVE games and deploying to itch.io, CD-style

Makefile

# Simple-ish Makefile for building LOVE packages to multiple architectures and publishing to itch.io.
#
# Useful targets:
#
#   all - build for Windows, OSX, and LOVE bundle
#   publish - deploy the build to itch.io
#   publish-status - print the itch.io status
#
# The itch publishing stuff uses itch's "butler" mechanism. Read more at https://itch.io/docs/butler/
#
# This build environment is set up with the following things in mind:
#
#   top-level game directory is in src/
#   baked assets live in src/assets/
#   there's a script called ./update-art.sh that automatically bakes assets from raw_assets/
#
# Implementing that for your own needs is left as an exercise to the reader. :)

# itch.io target
TARGET="fluffy/colorful-critter"

# game directory
SRC=src

# build directory
DEST=build

# Application name
NAME=ColorfulCritter

# LOVE version to fetch and build against
LOVE_VERSION=0.10.2
