But, on the other hand, we would have the advantage of not being able to move the background accidentally in the editor (which happens sometimes), which could be useful, although not really important at all.

I have this problem all the time. Cause when i want to select some tiles to move it and i have a background tile. it just moves the background tile instead of selecting. It requires some puzzling to bypass this problem.

In the tileset options you can set up a background color for the map. For the Light World it is green for example.

It would be very cool if there was an option to overrule that option in the map settings. For example. I like to create a desert and for that i need the Light World tileset, but the Light World tileset has that green background, which is not very useful for a desert map. So i'd to have a yellowish color as background instead.

Is that a good idea for Solarus?

Side-request of this idea:
It'll be even better if we can set up the 'tiletype for the 'background. Like traversable, deep water, grass etc....
It would be cool if we can do this in the tileset settings as well as the map settings to overrule it (like above's idea).

Just for reference purpose, here's a really old doc that explain how to implement a lot of special effects in a 2D RPG game.

The code relies on DirectDraw so it's not really usefull as is but it may give a good starting point for the math calculation involved.

The text is in french.

Looks like an interesting doc. Unfortunately I can not read it, because i don't know french.

I developed the idea of creating an underwater dungeon for my game.

So i wondered if it would be possible to create an underwater distortion effect, like for example Jabu Jabu's Belly in Oracle of Ages.

Would be very cool if it can.

Can't you use the same system that works with the sword collision on walls to find weak walls that can be bombed?

It would be really helpful if there was an indication in the map editor where you can see what groundtype a tile is.
I already asked about a movement permission view in another thread. This is kinda an addition to it.

When moving the mouse cursor over the map editor you see in the lower left corner something like this:
176,520 - Tile
or 176,520 - teletransporter
etc...

At the tile one it could be very helpful if it says what groundtype the tile is.
Example: 176,520 - Tile (traversable)
or 176x520 - Tile (deep water)
etc..

I thought to show you some screens so you can see what i am developing.


This is a brewery. Yes, it will serve beer and ale.


Beach (unfinished)

And for who noticed that the second screen is a bit darker/more saturated color. That's right. I changed tileset to a darker color. The 'black' color is more black now. The upper was screen was of before that change.

I was wondering if it would be possible to create a dynamic teleporter.
So one teleporter leads to different destinations based on an event.

The idea I have is to create a dungeon system which changes when defeated to a harder version of the dungeon so you have a reason to go back to gather more.

What way could be the best way to do it?

I notice some strange behavior of the Solarus Quest editor lately.

Sometimes, randomly, Solarus Quest editor tries to change the description of the map by adding the tile information. Sometimes this causes that project_db.dat becomes unusable, because strings are not right anymore.

Error message i received:
Error: Failed to load data file '<insert project path here>/data/project_db.dat': <insert project path here>/data/project_db.dat:20: unfinished string near '"<mapname here>tile{'

Then it tries to add a long list of these tile setups:
tile_pattern{
  id = "10",
  ground = "traversable",
  default_layer = 2,
  x = 680,
  y = 208,
  width = 16,
  height = 16,
}

It's certainly not my fault. Im sure of that. I do have added lots of custom tiles and sprites however.

I was thinking if you couldn't do something with creating a world and use maps shifting with  location in its world coords.

I am wondering if don't need something else to get the variable data saved.

I did the change, but i still don't get the done dialog.

Learn how to read Lua error messages
You have a syntax error at line 16. There is no "end" of the function started line 7.

I got it almost working now.

Code (lua) Select Expand

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

function oldman_npc:on_interaction()                              -- oldman_npc is the name of the NPC

  if not game:get_value("oldman_helped_4B") then
    game:start_dialog("oldmans_cave.question", function(answer)   -- Old mans asks a YES/NO question
      if answer == 2 then
        game:start_dialog("oldmans_cave.answer1", function()      -- Answer YES >> Get 20 rupees
          hero:start_treasure("rupee", 3, "oldman_helped_4B")
          oldman_helped_4B = true
        end)
      else                                                        -- Answer NO
        game:start_dialog("oldmans_cave.answer2")
        return
      end
    end)
  else
    game:start_dialog("oldmans_cave.done")                        -- Old man refers to the 20 rupees he gave.
    return
  end

end

The ELSE part starting on line 18 or the part where to save a variable does not work yet. I am not seeing the variable in the quest.dat

OK, changed that to oldman_helped_4B instead.

Now this error:
Error: Failed to load script 'maps/interior_4B/oldmanscave': [string "maps/interior_4B/oldmanscave.lua"]:16: unexpected symbol near ')'
Error: In maps/interior_4B/oldmanscave: attempt to call a string value

Still no dialog btw.

I got an error:

Error: Failed to load script 'maps/interior_4B/oldmanscave': [string "maps/interior_4B/oldmanscave.lua"]:11: malformed number near '4b_oldman_helped'
Error: In maps/interior_4B/oldmanscave: attempt to call a string value

I'm trying to create an advanced dialog, but i can't get it work.

I got this:

Code (lua) Select Expand

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

function oldman_npc:on_interaction()                            -- oldman_npc is the name of the NPC

  if not game:get_value("4b_oldman_helped") then
    game:start_dialog("oldmans_cave.question", function(answer) -- Old mans asks a YES/NO question
    if answer == 2 then
      game:start_dialog("oldmans_cave.answer1", function()      -- Answer YES >> Get 20 rupees
        hero:start_treasure("rupee", 3, "4b_oldman_helped")
        4b_oldman_helped = true
      end)
    else                                                        -- Answer NO
      game:start_dialog("oldmans_cave.answer2")
      return
    end)
  else
    game:start_dialog("oldmans_cave.done")                      -- Old man refers to the 20 rupees he gave.
    return
  end

end

Why is this not working? I don't get a dialog at all when hitting the action key in front of the NPC.
