lua example

[Marbit]

I'm having a lot of fun with vaults but lua is still foreign to me. Could you help me with a very basic example?
In the vault "M" is supoused to be transparent wall and disapear if you join Xom.

  Code:

NAME:   lua_test
TAGS:   no_rtele_into no_item_gen no_monster gen temple_overflow_xom uniq_altar_xom
ORIENT:   float
WEIGHT: 3
KFEAT:   X = altar_xom
KITEM:  , = snozzcumber

.......
.nnn...
.n,M.X.
.nnn...
.......

I'm afraid I can't help you, but I can recommend you post this in the contributions forum, where the people who know your answer are probably more likely to see it. They may see here too, but I'd try contributions.

I'm afraid I cannot move the post but if an admin considers that necesary, by all means do it.

Hit the report button (the little exclamation point next to quote) and request a move.

(no experience with it, just guessing here)
define a "border" for your map, and use the "Murray drop" mechanism from one of the Sprint maps
so that when you reach the border, it triggers the code that replaces M

Look through some of the existing altar vaults, I think there are some that have effects when you join a god.

[prozacelf]

There's an Ash vault where the walls turn transparent and you can see what Lair branches you'll have to deal with. It happens regardless of whether you join Ash or not, but you can probably get an idea of how it's supposed to work from that. And I'm sorry, but I have no idea what that vault is called.

That won't hugely help with performing an action on joining a God.

But has the poster looked through the Lua triggerables documentation: https://crawl.develz.org/wiki/doku.php?id=dcss:help:maps:lua:triggerables

Yes, I have seen the obscure documentation on triggerables. It is a bit hard for me.
I had checked many vaults and I came with a solution but it was overly complicated: I plan to make give a message if the player steps on Xom's altar, wait a few turns, check if the player is following Xom and if so destroy the glass wall. I think I can manage to put this together but it is very messy, surely there is an easier trigger (so far I haven't found any in the existing vaults).

So far the code only checks if you step on the altar and if you are a demigod or follow Xom.

  Code:

{{
function callback.xom_warn_stepped(data, triggerable, triggerer, marker, ev)
  local x, y = marker:pos()

-- This checks to see if you worship Xom or are a demigod. If you do/are then
-- you get a negative message but if you don't, Xom invites you to worship
-- him in exchange for a small gift.

  if you.god() == "Xom" then
     crawl.god_speaks("Xom" , "No soup for you!")
  elseif you.race() == "Demigod" then
     crawl.god_speaks("Xom" , "Broken toy no fun!")
     dgn.grid(x, y, "floor")
  else
     crawl.god_speaks("Xom" , "I want a new toy, come to me and take your price!")
  end
end
}}

tm2:add_triggerer(DgnTriggerer:new{type="player_move"})
lua_marker('X', tm2)
}}

Yes, the triggerables documentation is pretty bad. So far nobody has stepped up to improve it

I don't think there is actually a trigger for joining a religion. One could probably be added if there's an interesting reason to do so. But one way you could work around it is this:

- Once the player has stepped on the altar, start a timed trigger (you should be able to use master/slave to do this)
- Use this to check every turn if the player's religion has changed to see if they joined Xom
- Also check if the player is still on that square, if not you can stop the timed trigger (there's no point having a trigger going off every turn once the effect is over)
