Just adds a keybind (default "C") which sets the player to the crawling pose, allowing them to sneak through 1-block high gaps, without needing to squash something on top of them.
Version 1.1.0 onwards also adds a second keybind (not bound to anything by default) which allows you to toggle being prone.
Version 1.2.0 onwards has server side config options to allow/deny players going prone in certain scenarios (can be found in <world save>/serverconfig/goprone-server.toml).
Config defaults to:
- Allow jumping while prone
- Allow during flight (player not on ground).
- Deny while riding another entity (horse, pig, minecart, boat etc.). It also has an exceptions list. Any entities listed by their registry name (e.g. "minecraft:boat") will invert the rule.
Requires Forge. Not required on the client (Although clients without it will not be able to go prone).
You may use this mod in modpacks and/or videos without asking permission.
