rumble/init.lua

-- rumble - Client side mod for Minetest
-- Scripted by: Li0n

-- configureable settings:
local rumble_strength_max_standard = 0.5
local rumble_duration_max_standard = 5

-- To do list:
-- sadist mode
-- tnt griefer mode
-- log player name only once, after player is initialized.
-- editable table of words to trigger notification rumble
-- command to choose a word/name that triggers notification rumble
-- notification mode: trigger rumble from specific words written by either yourself or others
-- condense on/off commands into single commands. eg .chatlog on and .chatlog off instead of .chatlog_on and .chatlog_off
-- make a GUI for all the settings
-- make a section in the code where all default settings can be changed
