--Sprint mod for minetest by GunshipPenguin

--CHANGE THESE VARIABLES TO ADJUST SPRINT SPEED/JUMP HEIGHT
--1 represents normal speed/jump height so 1.5 would mean 50% more and 2.0 would be 100% more
SPRINT_SPEED = 1.30 --Speed while sprinting
SPRINT_JUMP = 1.10 --Jump height while sprinting
STOP_ON_CLICK = true --If true, sprinting will stop when either the left mouse button or the right mouse button is pressed
