Title: [Solved]How to get the hero in an item script?
Post by: zutokaza on June 06, 2017, 04:58:05 AM

I am wondering how to get the hero in an item script.

I want to do this:

Code ( lua) Select

--slow the hero down
function item:on_map_changed(map)
  hero:set_walking_speed(30)
end

I tried:

Code ( lua) Select

local item = ...
local game = item:get_game()
local hero = game:get_hero()

and

Code ( lua) Select

local item = ...
local game = item:get_game()
local map = item:get_map()
local hero = map:get_entity("hero")

and

Code ( lua) Select

local item = ...
local game = item:get_game()
local map = item:get_map()
local hero = map:get_hero()

One solution is using "self". I did this when making boots that speed up walking.

Code ( lua) Select

function item:on_obtaining()
  self:get_map():get_entity("hero"):set_walking_speed(120) 
end

if game:get_value("sola_house_f1_heart_gem_finish") then
  function item:on_map_changed(map)
    self:get_map():get_entity("hero"):set_walking_speed(120)
  end
end
