HUD just disappeared by calling "on_started()"

[HarleyDavidson]

I just copied all required scripts into my projects and the hud is displayed correctly.
But my hero is changed to the default tunic1 hero sprite, so I just wanted to change the sprite id.

Only the call of the function game:on_started() let the HUD disappear and I cannot figure out why.

Here's my game_manager.lua:

local game_manager = {}

local initial_game = require("scripts/initial_game")

-- Starts the game from the given savegame file,
-- initializing it if necessary.
function game_manager:start_game(file_name)

  local exists = sol.game.exists(file_name)
  local game = sol.game.load(file_name)
  if not exists then
    -- Initialize a new savegame.
    initial_game:initialize_new_savegame(game)
  end

  function game:on_started()
  end

  game:start()
end

return game_manager

Only the call of the function "game:on_started()" is enough to let the hud disappear,
I do not change or call anything in this function...
There's no error message in the console. 

Can anyone help me?

By defining the function game:on_started() here, you overwrite the one used by the HUD.
The correct way should be to define it as

Code (lua) Select Expand


game:register_event("on_started", function()
   ...
end)

instead of

Code (lua) Select Expand


function game:on_started()
   ...
end

Using register_event() is equivalent but allows to have several functions associated to the same event (on_started() here).

If a tutorial told you to write function game:on_started(), please tell me and I will fix it.

Thanks for this super fast reply!
Now it works, here's my script now:

Code Select Expand


local game_manager = {}

local initial_game = require("scripts/initial_game")
require("scripts/multi_events")

-- Starts the game from the given savegame file,
-- initializing it if necessary.
function game_manager:start_game(file_name)

  local exists = sol.game.exists(file_name)
  local game = sol.game.load(file_name)
  if not exists then
    -- Initialize a new savegame.
    initial_game:initialize_new_savegame(game)
  end

  game:register_event("on_started", function()
    local hero = game:get_hero()
    hero:set_tunic_sprite_id("main_heroes/dominik")
  end)

  game:start()
end

return game_manager
