Shaiya Library

[Cups]

I haven't been active in Shaiya in the last couple months as I've recently started a new job working on another game, which has been occupying my time. This library is a bundle of C++ functions and a Lua scripting implementation designed to make Shaiya development easier, and also contains a half-finished implementation of Ep8 packets.

This also contains a half-assed attempt at an "actor" system, which could be considered an artificial player disguised as an NPC for "intelligent" npc systems, though this is far from implemented. Unfortunately, I no longer have the Lua scripts on hand, but it shouldn't be too hard to figure out





I can't help you a whole lot with the scripts other than providing a few examples that I toyed around with, but you should be able to figure it out from reading the functions and models that is exposed in the ShaiyaScriptingEngine project.

:
NAKED_MAP_ID = 60 -- The map id for naked events to be hosted on

-- Disallow users to equip items on the naked map
on_can_equip(function(user, item, slot)

    if (user.map == NAKED_MAP_ID) then
        user:send_notice("You cannot equip items on this map!")
        return false
    end

    return true
end)

The following are valid functions:

on_login(function(user)
end)

on_enter_map(function(user))
end

on_item_effect(effect, function(user, variant)
end

on_can_recreate(function(itemdef, runedef, stats)
end)

on_recreation(function(itemdef, runedef, stats, maxreroll, rerollcount)
end)

on_can_equip(function(user, item, slot)
end)

The list of types:

/**

 */
void ScriptingEnvironment::defineUser() {
	using namespace Shaiya::Models;

	lua.new_usertype<CUser>("user",

		// Get user fields

Good luck!

What version of Visual Studio? I am trying to compile with 2013.
Can you post the compiled file please?

I used 2017, but there are a few libraries you'll need to find to get it compiling correctly (you can find these referenced in the vcxproj files)

• LuaJIT
• Boost 1.70

I've also attached the compiled libraries and DLL. Please note that this compiled copy by default searches for scripts in the "./Eden/Scripts/" folder, relative to your ps_game. The DLL should be injected into the ps_game. This compiled copy does not load any of the Ep8 code, though can be enabled by compiling from source.

Make sure to start the Injector / Cheat Engine as Administrator

Thanks for trying to help but, have I tried before and the same thing happens, any other solution?

This is why I suggested you build it yourself :P It's trying to load Lua libraries but you don't have any.

This is just AWESOME!!!

Hi there, i had same problem as you did, looks like you need to inject it using cheat engine 6.4 .

Judging that lua files are used as AI for mobs, if i create a file called Etain.lua it will run my code or is there anything else I should do ?

nop, you need to open ShaiyaEden and dllmain.cpp create this folder: /Eden/Scripts and install libary lua for use lua51.dll, i think.

Would it be possible to do something like that in the lower episodes, like 6 or 5.4?

Use other cheat engine , 7.4 should work.

Do you have a database of EP8?

Hi @,

Already compiled it. But it seems to be not working, when i tried to inject it, I encounter some error, related to allocation memory. I wonder if there's a fix for this.
