--Potions by Traxie21--
--This mod provides no default potions. If you would like some, download potionspack at github.com/Traxie21/potionspack--
--API DOCUMENTATION--
Potion Registering Format:
potions.register_potion(NAME, COLOR, EXPIRE TIME, ACTIVATION FUNCTION, EXPIRE FUNCTION)
NAME: Name of potion. Invalid characeters are automagically stripped from it.
COLOR: Color of potion image in-game, available colors: black, brown, cyan, darkblue, darkgrey, lightgrey, darkred, dull, green, orange, pink, purple, red, white, and yellow.
EXPIRE TIME: Number in seconds.
ACTIVATION FUNCTION: The function that is run when the ground is right-clicked with the potion.
EXPIRE FUNCTION: The function that is run when the expire time runs out.
--EXAMPLE--
potions.register_potion("Anti Gravity", "purple", 60,
function(itemstack, user, pointed_thing)
user:set_physics_override(3, 1.5, 0.5)
minetest.chat_send_player(user:get_player_name(), "You have been blessed with Anti Gravity for 60 seconds!")
end,
function(itemstack, user, pointed_thing)
user:set_physics_override(1,1,1)
minetest.chat_send_player(user:get_player_name(), "Anti Gravity has worn off.")
