About this project
What does hmc-optimizations add?
Version specific optimizations for HeadlessMc. The goal of HeadlessMc is to make the Minecraft client run on the command line, headless. It does so by hooking into the LWJGL library skipping all the code. This also makes it largely Minecraft version independent, as we only have to target the LWJGL library.
However, all the Minecraft code for rendering will still run; it is just the calls to LWJGL that do not do anything. Also, due to the inextensible nature of Javas Buffers, the LWJGL library patched by us still needs to allocate buffers when Minecrafts code tells it to, currently on the heap instead of off.
The goal of this project is to write mods that target Minecraft code specifically, patching out anything rendering related with Mixin.
