[C++] Dll can interpret lua script?

[WinSocket]

I wonder how it is possible to work with C + +
I am intending to make edits in high level language via DLL, more I wonder if the following is possible.:

Make a dll interpret a lua script and edit the executable



_________________________________________________________________________________
Example.: I know the emu can interpret lua scripts... can i create a dll and load this on my executable?

sorry my bad situation.

wtf are you talking about??? What has LUA to do with editing the executable?

 

[WinSocket]

can i use LUA scripts to run movements on game/server with dll?

 

[SheenBR]

no you cant

 

[WinSocket]

okay, thanks you.

Do you mind telling us what you where trying to do? I think we are misunderstanding each other.

You can edit lua scripts without intercepting them since they are "external" files that are loaded at start.

At first I'm not doing anything yet as this is still under study.
Most like to know if it is possible to use scripts lua, to make the game effects such as spells or even move the character otherwise.

You had made a new movement in the rider, can you tell me how it was made?
thanks.

 

[Vormav]

You can't use scripts to do character animation, you need to build that animation separately.
Skills don't have to use lua scripts and in fact some of them don't. You can use 3d animation + pt functions to move or rotate bitmaps/models around your characters.

Find yourself one skill and start playing with values to see what you can do.
I recommend 1st priestess skill (heal). It have a bit of everything.

You had made a new movement in the rider, can you tell me how it was made?
thanks.

I don't understand.

By 'moon script' he means "LUA Script" (mistranslated, but elegant XD), and by 'Rider' he meant the Knight; he is asking about that 'X' attack skill you made to the Knight.

("Knight" is "Cavaleiro" in Portuguese, but "Cavaleiro" can also mean "a horse rider", so, in some languages, like Portuguese, the word "Cavaleiro" can refer to the nobility title ("Sir" Knight) and also to a man that rides horses ("Cavalo" = "Horse"), and 'Lua' = "Moon").

I think the only thing you can edit with LUA, is the particle stuff, effects and skills...

As you didnt say anything in your first post, I was assuming you wanted to add new features using LUA... which is kinda odd.

But possible.

You could implement a DLL which would run a LUA script and provided methods and properties to for memory addresses and permissions and so on.

It could then modify memory locations within the game, change x86 code, grant invisibility and flight, speed boosts, insta-kill, teleportation etc. Anything you like really. *If* you create the correct LUA API in the source for your DLL.

You could script packet insertion, trigger scripts on events, create graphical or text overlays or effects. Whatever you want.

Additionally, if the LUA DLL was common, any modification in LUA could be edited and passed around by players, and developed to be stronger or less buggy and such.

It's a great idea... but too powerful. XD

 

[WinSocket]

I bought a book for study and was reading that LUA is well recommended for use in most modern games. So I decided the one analyzed and see if anyone has more knowledge and maybe take some questions.

Bobsobol Thanks for the reply, I will see my possibilities and maybe a opensource project comes around.
Thanks sheen and vormav to explain too.

 

[bobsobol]

Yes... it's confusing because, there is a LUA interpretor build into PT which you couldn't change much even if you did build a DLL. The only APIs it provides are for animating special effects for skills and such.

However, you could build a second LUA interpretor (or Java Script or CScript or such) into a DLL and give it APIs for doing just about anything you wanted to... if you know the right places in the client to implement such a thing. LUA is great for prototyping and getting quick developments going.

Unfortunately, the easiest things to implement would be such powerful APIs that they would immediately be latched onto by hackers and cheats. :\ You'd have to be very careful how you designed any LUA API you introduce to PT to prevent malicious use and still be useful.

 

[WinSocket]

well bobsobol, if you create a dll server side and client side using sockets you might as well do some checks and changes using the server as sending and receiving client.

I thought a few times of doing this to update both tables item, spells as well as many checks that the client makes without server restart

 

[bobsobol]

That's not a bad idea. Have the server audit client side API use? Could be good.

Watch out for adding lag to the server, and consider cheaters using proxies to filter out your verification packets and fake server authorisation.

 

[WinSocket]

Yes, you have to be very careful with it. More can become easy if you use some validation techniques.
