There are various reasons for bypassing SpongeAPI and accessing the internal Minecraft implementation directly:
- A part of SpongeAPI is not implemented yet. In this case you can temporarily bypass the API in your plugins. However, in most cases the better option is attempting to contribute the missing implementation to Sponge so other plugin developers can profit from the implemented API.
- You need access to an implementation-dependent feature which is not supported by SpongeAPI (on purpose).
- You want to optimize or customize the implementation specifically for your server.
Depending on special implementation features will make your plugin only work on the implementation you build it against (and likely also only on a specific version). Unless you are certain that accessing the implementation is necessary we highly recommend building plugins only against SpongeAPI.
The following articles assume you build your plugin for SpongeVanilla/SpongeForge. The plugin will not be usable on any other implementation.
SpongeVanilla and SpongeForge use MCP as development environment for the internal Minecraft code. Continue at MCP (Mod Coder Pack) for a short overview about MCP or continue directly with Das MCP in Plugins verwenden for an introduction about using MCP in plugins.
