About

Nature2D is a 2D physics library designed for and on Roblox. Ever wanted to create 2D games but step back because Roblox doesn't have a built-in 2D physics engine? Use Nature2D to create versatile and smooth simulations and mechanics for your 2D games with minimum effort. Nature2D primarily uses methods of Verlet Integration and Convex Hull collisions.

RigidBodies and constraints can potentially be made with almost all UI elements, from Frames to TextBoxes. Create almost anything you can imagine. From bouncy boxes to destructible structures, even character movement in no time. Here's a wrecking ball connected to an invisible constraint knocking a few boxes off of the blue platform.

Getting Started

Using the CLI - You can clone the repository on your local device and start experimenting.

$ git clone https://github.com/jaipack17/Nature2D.git

Roblox Model - Nature2D is available on the Roblox asset store for free. You can get the model through the following link.

https://www.roblox.com/library/7625799164/Nature2D

Using .rbxm File - Head over to the Releases page on github, choose a version and download the Nature2D@x.y.z.rbxm file from its assets. Now right click in Roblox Studio's explorer, click Insert From File and select the file.

Using wally - Use wally, a package manager for roblox to install Nature2D in your external code editor. This requires wally to be installed on your device. Then, add Nature2D to the dependencies listed in your wally.toml file.

[dependencies]
Nature2D = "jaipack17/nature2d@0.7.1"

After that, Run wally install in the cli. Nature2D should be installed in your root directory. If you encounter any errors or problems installing Nature2D using wally, open an issue!

Require the library and start coding.

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local Nature2D = require(ReplicatedStorage.Nature2D)

local World = Instance.new("ScreenGui")
World.IgnoreGuiInset = true
World.Parent = game.Players.LocalPlayer.PlayerGui

local engine = Nature2D.init(World)

-- code

To get familiar with the library, you can go through the documentation. Documentation is available at https://jaipack17.github.io/Nature2D/.
