Lua, how do you check if a mod is installed.

I would like to add items made of materials from other mods (e.g. bronze and obsidian), but I do not want to add additional dependencies.

Is there an easy way to find out if a mod is loaded?
I am looking for something like:

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all

if (mod_loaded("obsidian")){
  minetest.register_craft(...)
}

Code: Select all

function mod_loaded(str)
  if minetest.get_modpath(str) ~= nil
    return true
  else
    return false
  end
end


That should work :D

or you could just not add a dependency that works for me on occasion its just if its trying to call a value on me the exists on the needed mod but that shouldnt be the case ie my bluilding blocks mod only needs default but theirs a bonus towel that uses the flowers mod :P

sfan5's answer is correct, but there is currently no way to tell Minetest which mods, if exist, should be loaded before your mod. Other than strictly depending on them, that is.

Patch welcome. (for example "?modname" in depends.txt)

Someone should make minetest.load_mod('bla')
