    This kind of support is great because it can give a lot more options to those who create servers.
    Great work, great release

        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) ?

                            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.

                            Everything is basically the same as in IW6x (documentation can be found here).

                            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
                            • Run the server (preferably with the -no-scripting flag to disable ChaiScript)

                            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)
                            

                            or

                            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 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
                            

                            To get the array's keys use the getkeys method:

                            local keys = player.pers.getkeys()
                            
                            for i = 1, #keys do
                                print(keys[i])
                            end
                            

                            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 (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)

                              1 - Copy the plugin to Plutonium/storage/iw5/plugins/
                              2 - Create a file in Plutonium/storage/iw5/scripts/yourscript/__init__.lua and 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.

                                    st0rm not sure why it crashes but doing this works fine:

                                    function onPlayerSpawned( player )
                                        game:ontimeout(function()
                                            if(player:hasperk("specialty_grenadepulldeath") == 1) then

                                        end, 0)

                                      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.

                                        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.

                                        Everything is basically the same as in IW6x (documentation can be found here).

                                        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
                                        • Run the server (preferably with the -no-scripting flag to disable ChaiScript)

                                        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)
                                        

                                        or

                                        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 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
                                        

                                        To get the array's keys use the getkeys method:

                                        local keys = player.pers.getkeys()
                                        
                                        for i = 1, #keys do
                                            print(keys[i])
                                        end
                                        

                                        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 (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)

                                          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.

                                          st0rm And regarding this, I don't know what you want to achieve, but if it works for you, in GSC I use this to deactivate the death streaks

                                          onPlayerKilled()
                                          {
                                              self endon("disconnect");
                                              level endon("game_ended");
                                              for(;;)
                                              {
                                                  self waittill("killed_player");
                                                  self.pers["cur_death_streak"] = 0; //Stop deathstreak
                                              }
                                          }
