Getting Started

ThunderKit is a Unity Extension developed by Passive Picasso (AKA: Twiner) that provides an expansive and expandable environment for mod development. It can be used for developing multiple mods in a single project, ease of testing by streamlining the building and testing processes with automation.

Why ThunderKit?

ThunderKit contains a good chunk of utilities and features that streamline the mod creation process, including but not limited to: - Multiple mod projects in a single unity project. - Automated creation of AssetBundles for RoR2 - Ease of creation on using ContentPacks. - Access to using the plethora of Scriptable Objects that Risk of Rain 2 has. (which reduces load time since normally by creating them in code it increases the mod's load time) - Give generally a close aproximation to what Hopoo uses to develop mods. - Easily manage DLL dependencies and mod dependencies. - Complete component access and editing via the Editor's Inspector - Loadable ingame assets using AssetRipper. - Simplified workload using Addressables with the AddressableBrowser

What do I need to get started?

One thing to keep in mind: Just like getting used to and learning any mod creation enviroment, learning the basics of ThunderKit and how to use it to its fullest potential takes time.
