    tModLoader

    tModLoader

    A mod to make and play Terraria mods. Supports Terraria 1.4

    tModLoader (TML) is an open-source, community-driven, modification and expansion of the Terraria game that makes it possible to make and play mods. TML expands your Terraria adventures with new content to explore created by the Terraria community! TML allows players to create and play Terraria mods and is designed in such a way so that you can play alone or together with friends, with one mod or with multiple mods, choose to play however you like! It is however required that all your friends also install TML if you want to play together; vanilla users can't play with TML users. First and foremost, TML is largely a community endeavor, built by the community; used by the community. Without all the contributions people in the community have made over the years, TML would not be in the state it is in. TML is a free-to-use modification of the game and will stay that way.

    OpenVR SDK

    OpenVR SDK

    API and runtime that allows access to VR hardware

    OpenVR is an API and runtime that allows access to VR hardware from multiple vendors without requiring that applications have specific knowledge of the hardware they are targeting. This repository is an SDK that contains the API and samples. The runtime is under SteamVR in Tools on Steam. The OpenVR API provides a game with a way to interact with Virtual Reality displays without relying on a specific hardware vendor's SDK. It can be updated independently of the game to add support for new hardware or software updates. This means that you can access the position of the headset using only one API call and it works for all headset brands (Oculus, Mixed Reality, Vive, etc)! The API is implemented as a set of C++ interface classes full of pure virtual functions. When an application initializes the system it will return the interface that matches the header in the SDK used by that application.

    JKSV

    JKSV

    JK's Save Manager Switch Edition

    This started as a simple, straight port of my 3DS save manager I publicly released in 2016. Despite not originally wanting to take it too far, I continued working on it for fun when I can. Dump and restore account save data. Dump and restore device saves shared by all users (Games such as Animal Crossing). Dump and restore BCAT Data. Dump and restore cache Saves. Dump system save data. Dumping this data is always enabled, but writing back needs to be enabled from the options menu. Writing to this can be very dangerous. Processes can be terminated from the Extras menu allowing you to open even more of these and explore more. Create save data so the user no longer needs to boot games to import saves. Titles can be rescanned from the Extras menu. For example, if you insert a game card while JKSV is open, rescanning will load and add it to the save creation menu(s).

    AlphaZero.jl

    AlphaZero.jl

    A generic, simple and fast implementation of Deepmind's AlphaZero

    Beyond its much publicized success in attaining superhuman level at games such as Chess and Go, DeepMind's AlphaZero algorithm illustrates a more general methodology of combining learning and search to explore large combinatorial spaces effectively. We believe that this methodology can have exciting applications in many different research areas. Because AlphaZero is resource-hungry, successful open-source implementations (such as Leela Zero) are written in low-level languages (such as C++) and optimized for highly distributed computing environments. This makes them hardly accessible for students, researchers and hackers. Many simple Python implementations can be found on Github, but none of them is able to beat a reasonable baseline on games such as Othello or Connect Four. As an illustration, the benchmark in the README of the most popular of them only features a random baseline, along with a greedy baseline that does not appear to be significantly stronger.

    Tiled

    Tiled

    Flexible level editor

    Tiled is a free and open source, easy to use, and flexible level editor. Tiled is highly flexible. It can be used to create maps of any size, with no restrictions on tile size, or the number of layers or tiles that can be used. Maps, layers, tiles, and objects can all be assigned arbitrary properties. Tiled's map format (TMX) is easy to understand and allows multiple tilesets to be used in any map. Tilesets can be modified at any time. Tiled is a general purpose tile map editor for all tile-based games, such as RPGs, platformers or Breakout clones. Tiled was originally written in Java. In 2008, work began to develop a faster, better looking, and easier-to-use version of Tiled based on the Qt framework. This decision was made as the Qt framework has a greater feature set than is offered by the standard Java libraries. Before you can compile Tiled, you must ensure the Qt (>= 5.6) development libraries have been installed as well as the Qbs build tool.
