EQEmulator Forums - Lua Example: Multitasking

Requires PEQ's Lua Multitasking Module: https://code.google.com/p/projecteqq...ad_manager.lua

This is an example of using multitasking through co-routines in Lua to make timer based scripts on unique npcs easier to write:

Code:

--Some_Crazy_Boss.lua

local ThreadManager = require("thread_manager");

local evt;



function ability_one()

        evt.self:Emote("begins to cast something electrical");

        ThreadManager:Wait(2.5);

        evt.self:Shout("Feel the thunder!");

end



function ability_two()

        evt.self:Emote("begins to cast something fiery");

        ThreadManager:Wait(2.5);

        evt.self:Shout("Feel the fire!");

end



function ability_three()

        evt.self:Emote("begins to cast something cold");

        ThreadManager:Wait(2.5);

        evt.self:Shout("Feel the freeze!");

end



function swapped_abilities()

        local i = 0;

        while true do

                if(i == 0) then

                        ability_one();

                        i = 1;

                elseif(i == 1)

                        ability_two();

                        i = 2;

                else

                        ability_three();

                        i = 0;

                end

                ThreadManager:Wait(15.0);

        end

end



function predictable()

        while true do

                ThreadManager:Wait(10.0);

                evt.self:Emote("begins to cast something predictable");

                ThreadManager:Wait(2.5);

                evt.self:Shout("Feel the Predictableness!");

        end

end



function event_combat(e)

        if(e.joined) then

                eq.set_timer("heartbeat", 500);

                ThreadManager:Clear();

                ThreadManager:Create("Predictable", predictable);

                ThreadManager:Create("Swapping", swapped_abilities);

        else

                eq.stop_timer("heartbeat");

                ThreadManager:Clear();

        end

end



function event_timer(e)

        evt = e;

        ThreadManager:Resume("Predictable");

        ThreadManager:Resume("Swapping");

end
