Noclip NEO

Pressing the toggle key switches noclip on, and the player can then move through the world and across terrain and structures. Breaking and placing blocks while in noclip is optional. The core stays small, so the mod adds only the basic noclip function unless the player turns on the deeper features.

The movement and time systems are configurable. Horizontal and vertical flight speeds can be set separately, with a linked mode for simple flight and an unlinked mode for precise control, and an optional inertia system gives momentum-based movement. A time control system changes the world time instantly or animates the transition while keeping Minecraft's lighting effects, which look good with shaders.

Noclip NEO runs on Forge and NeoForge, and it is needed on the client and the server, so both sides must run it. Files cover 1.20 – 1.21.11 across 19 release versions, and the code is covered by the All rights reserved license, so the mod is not open source.
