LuaRendering get ids of current scenario ("level")

[Bilka]

Split off suggestion from unrelated post

It would be nice if there was a magic variable like __SCENARIO__ that would always refer to the scenario (be it freeplay, sandbox, campaign, or some other custom scenario). That way sound.get_all_ids(__SCENARIO__) would return only ids made by the scenario and not any created by a mod. If there is one what is it and where is it documented? Only way I've considered on how to do it with LuaRendering is the hardway:

Code: Select all

--Pseudo code
local allids=rendering.get_all_ids();
local allmodids={};
local scenarioids={};
for name, _ in pairs(game.active_mods) do
  local modids=rendering.get_all_ids(name);
  for _,v in pairs(modids) do
    allmodids[v]=true;
  end
end

for _,v in pairs(allids) do
  if type(allmodids[v]) == nil do
    table.insert(scenarioids,v);
  end
end

--scenarioids now only has ids that don't belong to mods. Assuming my psuedo code is correct.

I made the get-all-ids and clear() function accept an empty string to mean "level".
