Calling functions across 2 separate lua scripts.

ViralXK · May 2013

Anybody know how to use functions across 2 separate Lua files?

I tried Script.Load and all I get in the game freaking out when I try to use it.

I also need help with calling Server.GetMaxPlayers() properly. I don't know if I'm doign that correctly either. I need an example of both really.

Edit: I think it may be more of a problem with me trying to call Server.GetMaxPlayers(). How do I exactly get the numbers of players the server can hold so I can use it in my script?

Once a script has been loaded anywhere, everything inside it (except stuff marked local) is available everywhere else.

There doesn't seem to be anything special about calling Server.GetMaxPlayers(). Just make sure that you're calling it on the server only, otherwise it won't exist.

Well my problem is, how do I get this information to the client because a lot of my client algorithms are based on player capacity of the server. Nothing works without this info.

I dont exactly know how I would get the info to the client. A lot of how this game works in a mystery to me

Anybody got example of how I would get this info to the client?

You'll need to modify an entity to make it transmit that data. Don't ask me which, I've never had to choose!

Do this:

// Put this in a file that is loaded by both the client and the server.
local newNetworkVars = { maxPlayers = "integer" }
Class_Reload("ChosenClass", newNetworkVars)

And this:

// put this on the server only
local originalFunc = ChosenClass.SomeFunc

function ChosenClass:SomeFunc(whatever_args)
    originalFunc(whatever_args)
    self.maxPlayers = Server.GetMaxPlayers()
end

You should then find that ChosenClass.maxPlayers provides the value you want on the client.

To send info about the game to the clients (for Xenoswarm) I ended up having to write an entirely new entity called GamerulesInfo which exists on both server and client, and then tell NS2Gamerules to create one when it is created and update it at the end of the OnUpdate function.. if you need a more detailed example hit me up on steam sometime and I can walk you through it!

A lighter example is to write a new network message and send it to clients whenever someone joins or the max players changes. On the client side you'd just set a global variable e.g. CurrentMaxPlayers from whatever you receive in that message.

I think I will give you a shout. This is pretty frustrating. I just want to send one number from the server to the client and it's apparently rocket science. I saw the network messages code and started to try and write one, but it doesnt work at all and it seems very strange and contradictory in the way it's written.

I had to do something similar to this today. Here is some code that works (make sure you are using an entry file):

Shared:

Script.Load("lua/Class.lua")
local gameInfoNetVars = { maxPlayers = "integer" }
Class_Reload("GameInfo",gameInfoNetVars)

Server:

local base_GameInfo_OnCreate = GameInfo.OnCreate
function GameInfo:OnCreate()
	base_GameInfo_OnCreate(self)
	self.maxPlayers = Server.GetMaxPlayers()
end

Client:

...
GetGameInfoEntity().maxPlayers
...

Um, did you not notice Client.GetServerMaxPlayers() and Client.GetServerNumPlayers()?

Artfunkel those last calls you posted dont work. Which still leaves me to write network calls to pass the info sadly. I appreciate all the help though.

Those functions are for a server, not the server. It's only used from the server browser.
