iw5-script

Lua scripting support for Plutonium IW5

Works the same as it does in IW6x

How

Download the latest version from the Releases tab
Copy it to %localappdata%/Plutonium/storage/iw5/plugins/
Create a __init__.lua file in a folder with a name of your choice in %localappdata%/Plutonium/storage/iw5/scripts/
Example %localappdata%/Plutonium/storage/iw5/scripts/myscript/__init__.lua

Below are some features that are not available or documented in IW6x

Chat notifies

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)

Alternatively you can use the game:onplayersay function to handle player messages:

game:onplayersay(function(player, message, teamchat)
    if (message == "!test") then
        player:tell("Hello world!")
        return true -- Hide the message from chat
    end
end)

Player damage/killed callbacks

Callbacks can be added using the game:onplayerkilled or game:onplayerdamage functions:

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)

Arrays

GSC arrays are supported and can be accessed similarly to gsc:

local ents = game:getentarray()

for i = 1, #ents do
    print(ents[i])
end

You can also create new arrays to pass them to GSC functions:

local arr = array.new()
arr:push(6)
arr:push(1)
arr:push(3)
arr:push(7)
arr:push(2)
arr:push(9)

arr = game:scriptcall("maps/mp/_utility", "quickSort", arr)

for i = 1, #arr do
    print(arr[i])
end

List of all array methods:

Name	Description
set(int/string key, value)	Set an array's value by index (integer) or by string, also works using the `[]` operator
get(int/string key)	Get an array's value by index (integer) or by string, also works using the `[]` operator
erase(int/string key)	Erase an array's value by index (integer) or by string, also works by setting the value to nil
size()	Returns array length
getkeys()	Returns a table containing all the array's keys
push(value)	Push a value to the array
pop()	Deletes the last element of the array and returns it

Structs

GSC structs are also supported similarly as the arrays.

To get an entity's struct use the getstruct method:

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[1].streakName = "ac130"
        player.pers.killstreaks[1].available = 1
    end)
end)

Note: you cannot create new struct fields but only modify or read existing ones, same thing for arrays

Functions

You can call 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" -- "&Hello world" is the equivalent of doing &"Hello world" in GSC
    end)
end)

To 'include' functions from files like in gsc you can do a similar thing:

local functions = game:getfunctions("maps/mp/killstreaks/_killstreaks") -- Returns a table of functions

level:onnotify("connected", function(player)
    player:notifyonplayercommand("use", "+actionslot 6")

    player:onnotify("use", function()
        functions.giveKillstreak(player, "ac130", false, true, player, false)
    end)
end)

Or this:

game:include("maps/mp/killstreaks/_killstreaks")

level:onnotify("connected", function(player)
    player:notifyonplayercommand("use", "+actionslot 6")

    player:onnotify("use", function()
        -- Included function names are lowercase
        player:givekillstreak("ac130", false, true, player, false)
    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)

Functions in variables can also be replaced with lua functions:

local levelstruct = level:getstruct()
local callbackPlayerDamage = levelstruct.callbackPlayerDamage -- Save the original function

-- The first argument (_self) is the entity the function is called on
levelstruct.callbackPlayerDamage = function(_self, inflictor, attacker, damage, flags, mod, weapon, point, dir, hitLoc, timeoffset)
    if (mod == "MOD_FALLING") then
        damage = 0
    end

    callbackPlayerDamage(_self, inflictor, attacker, damage, flags, mod, weapon, point, dir, hitLoc, timeoffset)
end

You can also detour existing functions in gsc scripts with lua functions:

local player_damage_hook = nil
player_damage_hook = game:detour("maps/mp/gametypes/_callbacksetup", "CodeCallback_PlayerDamage", 
    function(_self, inflictor, attacker, damage, flags, mod, weapon, point, dir, hitLoc, timeoffset)
        print(_self.name .. " got " .. damage .. " damage")

        -- Call original function
        player_damage_hook.invoke(_self, inflictor, attacker, damage, flags, mod, weapon, point, dir, hitLoc, timeoffset)
    end
)

player_damage_hook.disable() -- Disable hook
player_damage_hook.enable()  -- Enable hook

HTTP

HTTP functions can be accessed from the global http table:

http.request(url[, options]): Returns a table, you can replace the request's callbacks (onprogress, onerror, onload) with your own and send the request using the .send() method.

The second parameter is the options table, which should contain two other tables for the headers and parameters for POST requests.

local request = http.request("https://example.com", {
    headers = {
        ["Content-type"] = "text/html"
    },
    parameters = {
        foo = "bar"
    }
})

request.onprogress = function(progress)
    print(progress)
end

request.onerror = function(error, code)
    print(error, code)
end

-- Request is done
request.onload = function(data)
    print(data)
end
 
request.send()

http.get(url, callback): This function is simpler than http.request and only takes the url and callback as parameters.
```
http.get("https://example.com", function(data)
    print(data)
end)
```
