From 61802fe1064f96b5d723650d06072a6347a0748e Mon Sep 17 00:00:00 2001 From: Griffin Smith Date: Sat, 30 Oct 2021 12:12:47 -0400 Subject: feat(gs/xanthous): Allow throwing rocks Implement a first pass at a "fire" command, which allows throwing rocks, the max distance and the damage of which is based on the weight of the item and the strength of the player. Currently the actual numbers here likely need some tweaking, as the rocks are easily throwable at good distances but don't really deal any damage.
