# hbSprint
License: LGPLv3/CC BY-SA 3.0. Particle code Copyright (c) 2017 Elijah Duffy, licensed MIT.
## Description
A flexible sprint mod supporting stamina, hunger and coexistance with other physics altering mods.
## Notes
hbSprint can be played with Minetest 0.4.16 or above.
It supports on [hudbars](http://repo.or.cz/w/minetest_hudbars.git), [hbhunger](http://repo.or.cz/w/minetest_hbhunger.git) and [player_monoids](https://github.com/minetest-mods/player_monoids).
Thanks to [octacian](https://github.com/octacian/sprint/) for particle code.
## List of features
- Displays and drains stamina (by default, if hudbars is present). Hides stamina bar if full.
- Displays and drains satiation (by default, if hbhunger is present)
- Requires only forward key to be pressed, not left and right (by default)
- Requires walkable ground (no water sprinting)
- All variables customizable in Advanced settings or directly in minetest.conf
## Known issues
- Forward double tap support not implemented
