Thanks, but my problem is when 2 npcs (or custom_entities in my case) go out or enter the map at the same time (and at the same place of course). I already make them leave or enter the map, and there's no problem here. But as the set_ignore_obstacles() parameter is true, they are passing through each other. And the result of this is odd.

Hello,

I was wondering if it was another way to make custom entity go outside of the map limits. For the moment, I use movement:set_ignore_obstacles() with some positions test to make them go out and in but I wanted to know if there was another collision test with maps limit. I tried custom_entity:set_can_traverse_ground with empty ground but as I expected it doesn't work !

My problem is that I wanted that my custom entity (or npc) go outside and inside the map, but if I two of these entities walk in the same position (or if the 2 bounding box overlaps), they will be stucked if I set movement:set_ignore_obstacles() to false when they enter the map. And I can't let it to true, otherway they will not be obstacles in the map.

If someone has a solution, it would be great !
Thanks.

Hello, I did something to create a "non destructible objet" using the metatable of destructible. When the carried object stop its movement, a new destructible is created instead, at the "landing"position. It's like the object can be carried and thrown again and again.

    function destructible_meta:on_lifting()
    local map = self:get_map()
    local hero = self:get_map():get_hero()   
    local sprite = self:get_sprite():get_animation_set()
    local name = self:get_name()
    local entity_state = nil

    if name ~= nil then
      sol.timer.start(map, 10, function()
        if hero:get_state() == "lifting" then
          entity_state = hero:get_state()
        end
        if entity_state == "lifting" and hero:get_state() == "carrying" then
          entity_state = hero:get_state()
        end
        if entity_state == "carrying" and hero:get_state() == "free" then
          entity_state = hero:get_state()
          for entity in map:get_entities_by_type("carried_object") do       
            function entity:on_movement_changed(movement)
              local x,y,layer = entity:get_position() 
              if not map:has_entities(name) then
if name:match("^non_destructible") then
  map:create_destructible{name = name, layer = layer, x=x, y=y, sprite = sprite}
  entity:remove()
        end
              end
            end
          end
          return false
        end   
        return true
      end)
    end
  end


In your case, you have to test the position with the ground's one and if it's a hole, change the animation with the falling one. (and of course, not create the new object !!)

For one time I am not asking for help, I'm glad to help someone else !

Thanks a lot, Grand Master of Solarus ! It was more easy than I expected !! 
I just have to add get_name()  to make it work !

local destinations = {}
for destination in map:get_entities_by_type("destination") do

Hello !! Long time no see !

I'm wondering if it was possible create a table with map entities ?
Here is my need :
I want to create some npc randomly on a map, but, I want those npc to be created on random destinations already on the map. I found how to do, but I have to make a table with all destination manually, and I wanted to know if it was a possibility to automatically generate a table with all map destinations (it could be usefull if the map had 50 or more destinations)

I think that using the map data file could be a solution but I don't see how to do it... (maybe with parsing the map entities corresponding to a destination ?)

Thanks in advance for solutions

Hello, I don't know if it was already suggested, but I was wondering if it was not possible to add the function "set_drawn_in_y_order" to the npc (the generalized one). I explain myself :
I often have to create a custom entity to replace a generalized NPC because the sprite is more than 16x16 pixel. This could be useful to create a big stone or a letter box or whatever taller than 16 pixels without coding a dialog function in a custom entity and it could avoid to have a lot of them in the entities folder, especially if they are useless (just for a dialog).
Maybe it's not possible or not necessary because custom entity make it, but I think it could be easier to make some "big readable things".

PS: I was thinking of it and it could be usefull for all map entities !

Good job Diarandor! It works fine with the line self.choices = {} added.

Edit: Diarandor might have the solution

He definitely had the solution. 
Sorry to have opened an issue on github for a script error... (I don't even think to check it, and even if I checked the script, I'm not familiar with all the subtility of the lua language)

I use the alttp dialog box. The one in the ressource pack.

Done ! I put an issue on github : https://github.com/solarus-games/solarus/issues/1016
I was wondering if my dialog code was right, but I don't think it was the problem.

Hello! I don't know if it is a bug,if someone already told it, or if it's just my mistake, but when I wanted to ask a question with 3 answers, if one of this answer has another question with only 2 answers, the cursor moves like there was 3 answers, like the first question(even if the fourth line is blank, or the answers start on the third line, the cursor moves on line 2,3 and 4

I found why it was like that, but I don't know if it's normal: in my dialog, I put all the questions in the same sub directory like this :

- somedialog.question.question1
- somedialog.question.question2

question1 having 3 answers, question2 having 2 answers. When testing, there's the bug I mentionned.

To avoid the bug, I had to do this.
- somedialog.question1.question
- somedialog.question2.question

Did anyone already see this ?

Hello. I didn't come here since a long time, but I visit the forum this morning and saw your post. I think that maybe with layer, and transparent tile, you should do something. i.e put your item on the tile in the upper layer, and make the layer change when the hero jump. I don't know if it works, but it's an idea I had.

Thanks a lot! But for now I'm just working on other things and I don't want to put my head into this. But when I will have some time, I'll look it and maybe this time I'll ask for your help !

My scripts are not exactly to make secondary heroes as followers, they stay stopped until you switch, so it's not exactly the same mechanics, only the switching hero function will be similar.

Well, since my second character can also be stopped on a map, I think it was the same. I don't see your script, and maybe it could be usefull for me for some little trouble I have (especially with tunics which is not save in my script, so I have to use a trick to do it)

Hello and Happy New Year everyone (It's still time!) ! So, it would be like Secret of Mana (and seiken 3) on SNES ! I've done this with my game (to test the follower without changing the leader) and it works. (I don't use Diarandor's script because I've my own, but it should be the same!)

Hello !
I've done something like this when I developped the lens for my project with RM2K. I didn't make it yet with solarus but I have a lot of things to do before !!
