I've made a little script/ fishing game where your fish wins you prizes...everything works fine until i save and reopen the file...its basically:

Code Select Expand

if size <= 6 then
blah
elseif size >
win = size
size reset to 0

and then theres a seperate npc with a dialog stating the win number:-

Code Select Expand


game:start_dialog("fisherman.young.talk.weight.tank", win, function()


now if i move maps and come back in it all works fine...but if i save the game and return...the value of "win" is set back to nil, how do i get the value of win to save?

or do i need to make save variables for each outcome..ie

Code Select Expand


if win = 1 then
game:set_value("win_is_1", true)
else if win 2 then.....


and then write out a dialog for each outcome?

When i close the game on certain maps, this pops up...

libpng warning: iCCP: known incorrect sRGB profile
libpng warning: iCCP: cHRM chunk does not match sRGB


does anyone know what it means?

Hey Guys, I was wondering how to make a sort of code or password, as in enemy must be killed in a certain order to open a door/make a chest appear..so that if they are killed in the right order then x will happen but if the wrong order then everything is reset....

where would i start with this?

so that (1,2,3) opens the door but all other variants eg, (3,2,1) (2,1,3) ect would reset?

literally stuck at the start with this one...

would i have to make a bunch of save variables for each on_killed? depending on which have been killed before it?

I was wondering if you can make this item specific? it seems to activate if any item is used..eg.

Code Select Expand

function custom_sensor_1:on_interaction_item(boomerang)
sol.audio.play_sound("secret")
end

function npc_1:on_interaction_item(boomerang)
sol.audio.play_sound("secret")
end

this would be activated if i used a bow or any item at all.

is there a different way to have something happen when an certain item is used in a specific place? maybe im looking in the wrong place?

Hey, long time. I was working on an item the other day and wondered if there is a way to check for entities on the map on use..I was trying to make something that would freeze an enemy if it exists

ie.

Code Select Expand


function item:on_using()
  item:check_enemy()
  if entity type enemy then
    enemy:freeze()
    --function of item, function()
     enemy:unfreeze()
    end)
  else
    --function of item
  end
  self:set_finished()
end

function item:check_enemy()
--check map for enemies
end


hey, how do you get a dialog box to close itself rather than having to have an action pressed? is this possible? Id only want to use this in "cutscenes" and such, not in regular interactions with npc's

eg

Code Select Expand

game:start_dialog("this_needs_interupting", function()
  sol.timer.start(map, 1000, function()
  game:stop_dialog()
  end)
end)

according to the documentation this is possible but i cant seem to make it work, would it also need a different function if the dialog was more than 3 lines? (not a problem to make things 3 lines if dialogs can be "auto closed")

I've been thinking about combo's again like many other before and i was wondering whether its possible to have one item call another within a timer to kind of...pretend its a combo

eg... 'item A' on use
       create timer, if 'item A' used again within timer then
        use 'item B'

would this be possible?
is this a stupid way to do it?
is there a better way?

hey, i used to run this at the start of game set the video mode.

Code Select Expand

function sol.main:on_started()
-- Set Video Mode.
sol.video.set_mode("hq2x")

but now in 1.6 i get this :-
"Warning: The function sol.video.set_mode() is deprecated since Solarus 1.6. Use sol.video.set_shader() instead."

but when i change this :-

Code Select Expand

-- This function is called when Solarus starts.
function sol.main:on_started()
-- Set Video Mode.
sol.video.set_shader("hq2x")

i now get this :-
"Error: In on_started: main.lua:15: bad argument #2 to set_shader (shader or nil expected, got no value)
stack traceback:
[C]: at 0x01a54540
[C]: in function 'set_shader'
main.lua:15: in function <main.lua:13>"

I have the same issue in options_menu

Code Select Expand

      if self.cursor_position == 1 then
        -- Change the video mode.
        sol.video.switch_mode()
        self.video_mode_text:set_text(sol.video.get_mode())
      else

Warning: The function sol.video.get_mode() is deprecated since Solarus 1.6. Use sol.video.get_shader() instead.

but when i change that to :-

Code Select Expand

      if self.cursor_position == 1 then
        -- Change the video mode.
--        sol.video.switch_mode()
sol.video.set_shader()
    --    self.video_mode_text:set_text(sol.video.get_mode())
self.video_mode_text:set_text(sol.video.get_shader())
      else

i now get this error :-
"Error: In on_command_pressed: scripts/menus/pause_options.lua:229: bad argument #2 to set_shader (shader or nil expected, got no value)

I looked at the scripts for the development games and on github and they have the same script in pause_options.

Hey, I've been away for the longest time but the 1.6 update piqued my interest again. anyway i cant seem to get rid of this error message since updating, can anyone point me in the right path?

Does anyone know where the code is which selects the sounds entities make? I want to change the noise the chest makes when opening, I know how to change it for a chest on a map (as below), but i wanted to change all the sounds from the Alttp ones, like I also want to change the noise a block makes when pushed and so on.

function chest:on_opened()
  sol.audio.play_sound("chest_small")
end

Hey, I've tried to make a simple npc script, but for some reason it only seems to work half the time....i can load the map and it will work....then literally close and re-open the console and it wont work anymore...then next time it might. It seems like it works about 20% of the time, can anyone tell me the reason for this? Just trying to make her walk at the 1st time on the map up to her point she will be at for the rest of the game and freeze the hero until she is there and has spoken her initial dialog, its the interaction bit at the end which seems to be failing i should mention

Code ( lua) Select Expand


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

if game:get_value("open_walk") then
  girl:set_visible(true)
  fake_girl:set_visible(false)
  else
  girl:set_visible(false)
  fake_girl:set_visible(true)

local npc_movement_2 = sol.movement.create("target")
  npc_movement_2:set_speed(64)
--  npc_movement_2:set_smooth(true)
  npc_movement_2:set_ignore_obstacles(true)
  npc_movement_2:set_target(girl)
  npc_movement_2:set_ignore_obstacles(true)
  npc_movement_2:start(fake_girl, function()
  girl:set_visible(true)
  fake_girl:set_visible(false)
  game:start_dialog("girl.down_here")
  game:set_value("open_walk", true)
end)
end

function girl:on_interaction()
    game:start_dialog("girl.hello")
end


I also wanted to make the hero freeze on map start until this quest but I haven't been able to make that function yet, i know its hero:freeze() then hero:unfreeze()

I moved the end at line 24 to 29 and that seemed to help a little but it's still failing about 60% of the time

Hi guys, I've been trying to make a sensor which on activated a dialog will load from an NPC who will then walk off and vanish, I've tried to make it a save game variable so that the sensor and the NPC are gone forever after this. I can't seem to get my NPC to disappear when the map reloads, I realize the below will make him disappear when the sensor is activated again (which is what it is doing). Can anyone show me how to make it do what I need it to do. I tried lots of things but I can't seem to get it to work

Code ( lua) Select Expand


local meeting_quest_1 = false

function meeting_sensor:on_activated()
   if game:get_value("meeting_quest_1") then
   worker_npc:remove()
   else
      game:start_dialog("meeting.1")
      hero:freeze()
      local path_movement = sol.movement.create("path")
      path_movement:set_path({ 2, 2, 2, 2, 2, 1, 1, 0, 0, 7, 7, 0, 0, 0, 0, 0, 0, 0, 7, 7, 0, 0, 0, 0, 0, 0, 0 })
      path_movement:set_ignore_obstacles(true)
      worker_npc:is_traversable()
      path_movement:set_speed(64)
      path_movement:start(worker_npc, function()
      worker_npc:remove()
      game:set_value("meeting_quest_1", true)
      hero:unfreeze() 
      end)
   end
end


I kept getting these errors when i tried to get it working outside the sensor:on_activated
Error: attempt to index global 'worker_npc' (a nil value)
Error: attempt to index global 'meeting_sensor' (a nil value)
but as those are names of entities on my map...isnt that enough to use them just as : worker_npc:remove() ?

as in

Code ( lua) Select Expand


map:on_started(function()
if game:get_value("meeting_quest_1") then
worker_npc:remove()


does anyone know how to make a dialog where the npc will respond 4 ways based on whether i have neither item, 1 of the required items or both.

none     -   need both
sword  -   need shield
shield  -   need sword
both     -   have both!

ive been able to get it so that if i have neither and then one item it works. but when i try to get both, or either, i either cant get it to work or i get 2 dialogs trying to play at the same time (need this and need both)

ive tried setting things like below, but after this i dont know where im going, or if this even right to begin with

Code ( lua) Select Expand


local shield_search_quest_started = false
local sword_search_quest_started = false
local items_search_quest_started = false

  local has_sword = game:has_item("sword")
  if has_sword then
  game:set_value("sword_search_quest_started", true)
  end

  local has_shield = game:has_item("shield")
  if has_shield then
  game:set_value("shield_search_quest_started", true)
  end

  local has_both = game:has_item("shield" and "sword")
  if has_both then
  game:set_value("items_search_quest_started", true)
  end

-- Guy3
function Guy3:on_interaction()

if game:get_value("sword_search_quest_started") then
    game:start_dialog("Guy3.has_sword")
    else
         game:start_dialog("Guy3.search")
  end
end

-- the other 2 dialogs would be
-- "Guy3.has_shield"
-- "Guy3.found"

If anyone can help I'd appreciate it

In languages when making a new dialog for an item, you have the properties section. Where are the icons kept/what determines what makes icon 2 a bow for example? I changed the entities/icons.png but still the old zelda icon comes up when the dialog is showing.

Im making changes to my inventory names table and i was wondering whether it is possible to call a variant of an item from there? Could i call tunic variant 1 from there so i can also call variant 2/3 to be able to change tunic on pressed? Or would i have to just make 3 seperate tunic items? I know making the 3 seperate tunics would be easier.

Everything i have tried so far has resulted in errors

Can anyone explain how to get a pause menu (inventory and such) to work?

I'm only trying to get the one that Christopho uses in his French tutorial, I cant understand French so I'm just following what he does on his screen. I would be happy with the ALTTP inventory. I just need something which will enable me to switch between items.

Any help is greatly appreciated.

Could anyone help please I've got a couple issues since I've updated to 1.5.2

1. I can't get any dialog to load even though it is 100% there
Eg
Error: Missing treasure dialog '_treasure.flippers.1'

2. On collision with water (without flippers) the hero doesn't jump anymore he just drowns. He used on jump on collision with water (or lava)

Any help will be greatly appreciated
