This is Forge Mod Loader, or FML for short, by cpw. More information can be found at https://github.com/MinecraftForge/FML/wiki It is a clean reimplementation of a mod loading system for client, server and bukkit use, incorporating API implementations of client side ModLoader by Risugami. It can be installed on its own, or as part of Minecraft Forge. ---------------------- About Forge Mod Loader ---------------------- Environments and compatibility ============================== FML covers the three main environments: client, server and bukkit. All environments share the main mod loading code base, with additional varying hooks based on the specific environment. Compatibility is almost 100% with all ModLoader based mods- any mod with any difficulty (unless noted below) should be reported as a ticket to the github, please. Client side mods should be 100% compatible with ModLoader. The only exception is Optifine, however new versions of optifine are compatible. There are some very visible changes to the client when FML is installed. Server side mods are mostly compatible with previous MLMP based incarnations, however, this compatibility is not guaranteed. Most mods have adapted to FML and MLMP is not assured and will cause errors. Ask your mod author to update to FML. Bukkit side modding is an adaptation of the server side mod code to the bukkit environment. Mods need to be recompiled against the bukkit decompilation to work however there are guides and tools in development to make this process easier. Consult mcportcentral.co.za for more information. Minecraft Forge in all cases bundles FML as it's modloading technology of choice because FML is open source, freely distributable, and can be easily updated by contributors through github. Notable integrations ==================== Optifine has FML compatibility. It varies from Optifine release to release, however in general it will work well alongside an FML or Minecraft Forge installation. FML will detect and ensure the good operation of Optifine (you can see it in your client as an additional data line on the bottom left). Client notes ============ FML does provide a standard pattern for mods to provide HD textures. This is why optifine needed integration code. FML supports HD texture packs up to 128x resolution. Mod information =============== FML exposes the mod information through a mod list visible on the main screen as well as some small branding enhancements. For full data mods need to provide an information file. This file is a standard format so hopefully tools providing launch capabilities can also leverage this content. ------------------------------- Binary installation information ------------------------------- If you have downloaded a binary zip file you can install it as follows (client or server): Installation ============ To install on a server, simply execute the FML or Forge jar file, with a copy of minecraft_server.jar placed in the same directory. FML will launch it's patched copy. To install on a client, FIRST delete META-INF from the minecraft.jar file, then copy the contents of the FML or Forge jar file into it. FML and Forge provide their own META-INF data which should *not* be deleted. Forge Installation ================== This code also ships as a part of Minecraft Forge. You do not need to install it separately from your Minecraft Forge installation. Minecraft Forge contains the exact same code as this. Generally, you should not install FML if you are also installing Minecraft Forge. ------------------------------------------- Source installation information for modders ------------------------------------------- This code follows the Minecraft Forge installation methodology. It will apply some small patches to your MCP extracted source code, giving you and it access to some of the data and functions you need to build a successful mod. Note also that the patches are built against "unrenamed" MCP source code- this means that you will not be able to read them directly against normal code. Source pack installation information: Standalone source installation ============================== To install this source code for development purposes, extract this zip file into an mcp installation containing vanilla jars only. It should create a new folder "fml" inside that installation. Be sure that you have both vanilla client jars, and the vanilla server jar installed as per the MCP install instructions. Both are required for FML to run properly. Once extracted, run the install.sh or install.bat script provided from the fml directory. It should decompile and patch your MCP source code for the client and server. Forge source installation ========================= MinecraftForge ships with this code and installs it as part of the forge installation process, no further action is required on your part. For reference this is version @MAJOR@.@MINOR@.@REV@.@BUILD@ of FML for Minecraft version @MCVERSION@.
