Obsi 2 - Lua library for 2D game development.

Obsi 2 is a Lua library that was designed specifically for CC:Tweaked. Originally it was made as a game engine, but I have refactored it into a library for easier packaging.

Improvements in Obsi 2:

• More optimized obsi.graphics.rectangle function
• New obsi.graphics.getPalette function! (Yes, it didn't exist before. Also be aware that it creates a new table on every call. Sorry.)
• FPS counter that is accessible with obsi.timer.getFPS()
• Module obsi.filesystem was renamed to obsi.fs, and module obsi.time to obsi.timer
• Rendering APIs hmon and parea were renamed to basic and neat
• File extensions are mostly ignored (This is useful for when you have a system for converting nfp files to orli files, but don't want to bother with renaming every file in code)
• Fixed a crash when the game would play noteblock music in Minecraft
• Licenses from used projects are moved to LICENSES folder
• Some other changes that I forgot about

Switching from Obsi to Obsi 2:

There are a few things to look out for when switching to Obsi 2:

1. Now you have to include obsi2 as a library
2. In order for your code to be ran in the loop, you have to put obsi.init() at the end of your main file
3. Replace any mentions of obsi.filesystem with obsi.fs and obsi.time with obsi.timer
4. Move the code from config.lua file (it is no longer used by obsi) to the config inside obsi2/init.lua
5. Replace any mentions of hmon and parea rendering apis to basic and neat respectively
6. If the code outside of your main.lua file is also using obsi, then require it there as well. (Don't worry, require caches any of the packages it loads.)

Code with Obsi:

local img

function obsi.load()
	img = obsi.graphics.newImage("coolimg.nfp")
end

function obsi.draw()
	obsi.graphics.draw(img, 1, 1)
end

Same code with Obsi 2:

local obsi = require("obsi2")

local img

function obsi.load()
	img = obsi.graphics.newImage("coolimg.nfp")
end

function obsi.draw()
	obsi.graphics.draw(img, 1, 1)
end

obsi.init()
