[Release] Lua Scripting
As many of you probably know the current chaiscript scripting is pretty bad and has many limitations. This plugin implements lua scripting in IW5 and fixes all those problems.
- Download the latest version from the Releases tab
- Copy it to
- Create a
__init__.luafile in a folder with a name of your choice in
- Run the server (preferably with the
-no-scriptingflag to disable ChaiScript)
Below are some features that are not available or documented in IW6x
level:onnotify("say", function(player, message) print(player.name .. " said: " .. message) end)
level:onnotify("connected", function(player) player:onnotify("say", function(message) print(player.name .. " said: " .. message) end) end)
Player damage/killed callbacks
Callbacks can be added using the
Damage can be changed by returning it
Returning anything other than a number will not do anything (must be an integer)
game:onplayerdamage(function(_self, inflictor, attacker, damage, dflags, mod, weapon, point, dir, hitloc) damage = 0 return damage end)
game:onplayerkilled(function(_self, inflictor, attacker, damage, mod, weapon, dir, hitloc, timeoffset, deathanimduration) print(attacker.name .. " killed " .. _self.name) end)
GSC arrays are supported and can be accessed similarly to gsc:
local ents = game:getentarray() for i = 1, #ents do print(ents[i]) end
To get the array's keys use the
local keys = player.pers.getkeys() for i = 1, #keys do print(keys[i]) end
GSC structs are also supported similarly as the arrays.
To get an entity's struct use the
local levelstruct = level:getstruct() levelstruct.inGracePeriod = 10000
Structs in other variables like arrays are automatically converted:
level:onnotify("connected", function(player) player:onnotify("spawned_player", function() player.pers.killstreaks.streakName = "ac130" player.pers.killstreaks.available = 1 end) end)
Note: you cannot create new struct fields but only modify or read existing ones, same thing for arrays
You can call (will not work for every function) functions and methods within the game's gsc scripts using the
scriptcall(filename, function, ...)method:
level:onnotify("connected", function(player) player:onnotify("spawned_player", function() local hudelem = player:scriptcall("maps/mp/gametypes/_hud_utils", "createFontString", 1) hudelem:scriptcall("maps/mp/gametypes/_hud_util", "setPoint", "CENTER", nil, 100, 100) hudelem.label = "&Hello world" end) end)
Functions in variables such as structs or arrays will be automatically converted to a lua function.
The first argument must always be the entity to call the function on (level, player...)
local levelstruct = level:getstruct() level:onnotify("connected", function(player) player:onnotify("spawned_player", function() levelstruct.killstreakFuncs["ac130"](player) end) end)
This kind of support is great because it can give a lot more options to those who create servers.
Great work, great release
ill try to make a damage counter like repz gungame servers on iw4x
@Xx_Phoenix_xX i think this is what you mean
game:onplayerdamage(function(_self, inflictor, attacker, damage, dflags, mod, weapon, point, dir, hitloc) if (game:isplayer(attacker) ~= 1 or _self.sessionteam == attacker.sessionteam or _self == attacker) then return end local huddamage = game:newclienthudelem(attacker) huddamage.alignx = "center" huddamage.horzalign = "center" huddamage.x = 10 huddamage.y = 235 huddamage.fontscale = 1.6 huddamage.font = "objective" huddamage:setvalue(damage) if (hitloc == "head") then huddamage.color = vector:new(1, 1, 0.25) end huddamage:moveovertime(1) huddamage:fadeovertime(1) huddamage.alpha = 0 huddamage.x = math.random(25, 70) huddamage.y = 235 + math.random(25, 70) * (math.random(0, 1) == 1 and -1 or 1) game:ontimeout(function() huddamage:destroy() end, 1000) end)
Just a question: I don't know how to program, but with this Lua script is it possible to make smart bots (since it's impossible to make with the current chaiscript) ?
good job! finally see something good for mw3..
@Rosamaha Still won't allow you to set blocked commands on clients
@Xerxes good that gsc support comes soon ^^ sadly I stopped playing mw3 atm
@fed so how do i implement this on my game?
Put that in a file like
@fed does it work on all servers or only my own? btw nice gungame server its lots of fun
@fed It doesn't seem to work for me. I did the Damage Counter Script you made in the above comments. But It never worked, I neither know how to run it. (if you have to run it manually) Any Help?
1 - Copy the plugin to
2 - Create a file in
Plutonium/storage/iw5/scripts/yourscript/__init__.luaand copy the code into it
3 - Run the server
Looks like a great addition, I'll install Pluto IW5 to try this out.
I didn't notice any issues or development plan on GitHub. Looking forward to contributing to it.
@fed Thank you for adding the lua support. I've been trying to get
unsetperkto work but it seem it crash the server upon loading the script every time.
function onPlayerSpawned( player ) if(player:haspek("specialty_grenadepulldeath")) then print(player.name .. " is using marty") end end function onPlayerConnected( player ) local spawnListener = player:onnotify("spawned_player", function() onPlayerSpawned(player) end) end level:onnotify("connected", onPlayerConnected)
@st0rm not sure why it crashes but doing this works fine:
function onPlayerSpawned( player ) game:ontimeout(function() if(player:hasperk("specialty_grenadepulldeath") == 1) then print(player.name .. " is using marty") end end, 0) end function onPlayerConnected( player ) local spawnListener = player:onnotify("spawned_player", function() onPlayerSpawned(player) end) end level:onnotify("connected", onPlayerConnected)
Thanks Fed. That work just fine. I learnt the hard way the mw3 sets death perks in a really dumb way where there is not way to unset them since they're based on death streaks.
@fed I am trying to upload the plugin to the server, but I am getting the following error:
