Hi again Heroic Labs,

Loving Nakama so far, but I have one small question; I was wondering if it’s possible to load different authoritative multiplayer server modules through the lua function makematch()\*? For instance, a platform with minigames (each with custom game logic/modules), all available through the matchmaker.

Thank you!

@Korama Sure, the multiplayer engine in designed to let you register different match handlers with different names which can be created with the `MatchCreate` server runtime function. You can register different match handlers with code like you have above:

```lua
-- minigame1.lua
local nk = require("nakama")

return {
    -- implement all the match lifecycle functions
}

```

```lua
-- minigame2.lua
local nk = require("nakama")

return {
    -- implement all the match lifecycle functions
}

```

Then you’d create a match from one of the mini games with:

```lua
local matchid = nk.match_create("minigame1", { some = "initial input" })
-- OR
local matchid = nk.match_create("minigame2", { some = "initial input" })

```

Hope this helps.

Thanks @novabyte, that does help - but what I’m wondering is if there’s any way the _makematch_ function above can discriminate between different matchmaker queries, and thus load different multiplayer modules depending on what those queries are. C’est possible?

@Korama Yep, just look at the data properties passed in for the `"matched_users"`. For the match maker to return a match which fits what the players looked for each player would have needed to pass in the match type they’re interested in.

For example with a search query in the matchmaker like: `"+properties.match_type:minigame1"` the player has said they’re only interested to match against players who exact searched on the `"minigame1"`. Their data properties passed into the matchmaker would have looked like:

```auto
var query = "+properties.match_type:minigame1";
var stringProps = new Dictionary<string, string>() {
  {"match_type", "minigame1"}
};
var numericProps = new Dictionary<string, int>() {};
var matchmakerTicket = await socket.AddMatchmakerAsync(query, 2, 4, stringProps, numericProps);

```

You can extract these properties which each player matched by the matchmaker within the `"matched_users"` LTable in the Lua code above.

Perfect that’s exactly it! Thank you so much ❤
