Lua mission scriptin

is there a handy guide and command list for making the lua single player missions somewhere? im pretty poor at coding but it dosnt look to complex. sorry if there is already a thread, if there was I couldnt find it.

also, my lua aistartscripttest crashes with a c++ windows error, regardless of the AI set to apply to the teams

Read the wiki page already?

I knew most of that but cheers, i didnt have the list :D
Im making a set of 5 missions to help people get the hang of XTA, i was inspired by Thors pro NOTA missions.

any idea why adding AI crashes it?

right, only RAI works with mission building for some reason.
now, to get the hang of unit ordering.

is there a way of limiting resources in LUA missions?

1v0ry_k1ng · Post by **1v0ry_k1ng** » 09 Feb 2007, 20:00

is it possible to have several units of the same name, ie

self.myboi = units.Load("ARM_COMMANDER", float3(350, 16, 250), 0, false)
self.myboi = units.Load("ARM_JETHRO", float3(350, 16, 250), 0, false)

If I have self.myboi a move order, would they both move or would windows explode?

I think you can set the commanders' metal & energy storage values to something low when the mission starts.

EDIT: as for your 2nd question. I think there would be 2 units created, of which only the last one would move if you give it a command.
Use different variables to be able to reference both of them...

I have been working on a tutorial a few weeks ago, but haven├é┬┤t got it to a releasable stage yet. I thought it might be helpful for you though, so I├é┬┤ve uploaded it now:
http://spring.unknown-files.net/file/23 ... orial.lua/

As you will certainly notice quickly enough if you try it, its directed towards people who have no prior RTS experience (which I guess is highly unrealistic for anybody playing spring, but whatever :D ).
Also the bits I made will probably not be commented very well :/ . But feel free to ask if you want to know why, how I├é┬┤m doing something (not that I├é┬┤m doing much...)
Edit:
On giving multiple units orders, I don├é┬┤t know if the way you wrote does or does not work, what I know does work is the way its done in missiontest.lua (where I ripped most of my script from) :

Code: Select all

    -- Enemy stuff
    
    local first = {
        units.Load("CORe_AK", float3(1200, 80, 200), 1, false),
        units.Load("CORe_AK", float3(1200, 80, 300), 1, false),
        units.Load("CORe_AK", float3(1200, 80, 400), 1, false),
        units.Load("CORe_AK", float3(1200, 80, 500), 1, false),
        units.Load("CORe_AK", float3(1000, 80, 200), 1, false),
        units.Load("CORe_AK", float3(1000, 80, 300), 1, false),
        units.Load("CORe_AK", float3(1000, 80, 400), 1, false),
        units.Load("CORe_AK", float3(1000, 80, 500), 1, false)
    }
    
    local c = Command()
    c.id = Command.PATROL
    c:AddParam(1100)
    c:AddParam(80)
    c:AddParam(1000)
    
    for i = 1, table.getn(first) do
        first[i]:GiveCommand(c)
    end

Thus putting all the units you want as a group in an array, and then just having it loop the orders though for the whole array with the "for i = 1, ..." if I understand the code correctly.
Edit: P.S. , I think your XTA guide rocks, and think its great you want to make an ingame tutorial. While I probably don├é┬┤t have much time to spare in the next week or two, I would generally gladly give you a hand on making the an in game guide.

Can someone show how to limit resources? I haven't been able to get it to work, although admittedly my coding ability is not very good either. I hope it is possible. The kinds of missions that can be done without letting the player build anything are pretty limited.

Tobi · Post by **Tobi** » 10 Feb 2007, 11:09

It's impossible in current spring :/

Maybe spawn a tiny invisible unit that drains massive amounts of energy/metal?

AF · Post by AF » 10 Feb 2007, 18:53

A little bit of pseudocode to add in the update function

Code: Select all

a = getEnergy()
if(a > Energylimit){
    b = a-EnergyLimit
    AddEnergy(-b)
}

SeanHeron · Post by **SeanHeron** » 10 Feb 2007, 23:17

Thor, what exactly do you mean by limiting resources ? Do you mean limiting as in: not start with the crazy (but usefull for testing purposes) 200 k metal and 1000 k storage you get at the moment, but rather the standard 1000 each of metal and energy ? Cause than it might be an idea to have a look at the cmdrscript.lua . If you run that you start with the regular resources I think. No idea how its done though :/. Just let me check...

Tobi · Post by **Tobi** » 10 Feb 2007, 23:51

AF: AFAIK, all those functions do not exist.

Kujeger, that might work yeah, but it's a really hackish workaround...

SeanHeron · Post by **SeanHeron** » 11 Feb 2007, 01:08

Ok I was wrong, the cmdrscript starts with loads of resources as well. However I did find this:

Code: Select all

		class_<UnitDef>("UnitDef")
			.def_readonly("name", &UnitDef::name)
			.def_readonly("humanname", &UnitDef::humanName)
			.def_readwrite("metalstorage", &UnitDef::metalStorage) // readwrite so we can set commander's metalstorage at start of game
			.def_readwrite("energystorage", &UnitDef::energyStorage), // readwrite so we can set commander's energystorage at start of game

in the Luabinder.cpp
I├é┬┤ve tried playing around with it, but I don├é┬┤t really know how I would have to implement it. The bad news is, that I don├é┬┤t have the impression that loosing your com means loosing your starting storage, as it does in normal games, so maybe this isn├é┬┤t going to work anyhow :/ ...

Thor · Post by **Thor** » 11 Feb 2007, 01:12

Sean, yes, all I want is to start with 1000 resources. I've looked at cmdrscript.lua but can't find anything to do with it.

1v0ry_k1ng · Post by **1v0ry_k1ng** » 11 Feb 2007, 01:54

sean, how would you maniulate that code to give sane resources then?

SeanHeron · Post by **SeanHeron** » 11 Feb 2007, 13:12

Thats not actually code to put in a script, thats from the c++ file in which the lua commands and classes are defined (I think, to be honest I don├é┬┤t have much of an idea either). As stated above I haven├é┬┤t managed to actually use /get working the function: metalstorage, as I├é┬┤m not much of a coder myself :/. I just happened to have seen the comment in the code, and its obviously about what you (and me for that matter) want to get to make "building" missions possible.

Edit: well [edit: expletive deleted] me

, forget all of the stuff I said above and check out this thread. I was about to say apparently, cause I still can hardly believe it but I just tried, and You can call different startscripts from the script.txt (used by the lobby) ! That means you can easily start with 1000 1000 res, or do just about anything else thats possible with the lobby as well *Jaw drop*. The only thing missing is lobby support... But by using a manually edited script.txt, and starting spring via a shortcut with the argument script.txt it works fine (in easyspeak that is: make a shortcut to the spring.exe, open its properties, and then change its target to "[wherever you have spring]\Spring\spring.exe script.txt " . Then use the shortcut and viola

!). Wow ... where is Betalord

?
