how to find entity (entities) on map [Solved]

[Jouki]

Hmm @Jouki Delete the spaces around the i ok

still doesnt work

When building an entity name from variables and then retrieving that entity, you will want to do some string concatenation and use the "findEntity" function. The following first defines a flexible function that can turn on a whole bunch of lights that all start with the same ID in the editor and then defines a specific "utility function" that you can call from a pressure plate that turns on all lights in your dungeon that have the name "top_floor_lights_i" (where i starts at 1 and goes up to the last light it finds using this pattern).

Code: Select all

-- A generic function that will turn on the light and particle component 
-- for all entities in the dungeon that have the id "prefix_i" where
-- "prefix" is the parameter given to this method and "i" counts up from 1.

function turnOnLights(prefix) 
  local i = 1;
  local entity = findEntity(prefix .. "_" .. i);

  while entity ~= nil do
    if entity.light ~= nil then
	  entity.light:enable();
    end

    if entity.particle ~= nil then
      entity.particle:enable();
    end

    i = i + 1;
    entity = findEntity(prefix .. "_" .. i);
  end
end

-- 
-- This function is one you can hook into a pressure plate and it will 
-- turn on all lights in your dungeon with the name "top_floor_lights_i"
-- ie. top_floor_lights_1, top_floor_lights_2, ...

function turnOnTopFloorLights()
	turnOnLights("top_floor_lights");
end

Hope this helps!

holy... ok, it's working I should go through this code and learn as much as I can from that.
Btw. is there (I'm almost sure it is) something like 'sleep(2000)' (ms) I can handle cool effect "a slowly starting all-light effect" I mean turning them on one by one or any other way.

There's a view how it looks

I'm gonna hold off answering that for a short while... While I know that you could put a solution together using timers, I'm sure I read somewhere from Petri that there is a function you can use to just exactly this sort of thing (put a 2 second pause into a script). I'll try to find it, but I can't remember if it was a blog post or forum post or whether he posted a code example or just text! Lol

Glad you got it working.

that's ok, I forgot about timers. I can do that with timer and counter(s)
