[Release+Source=C++] Generate FULL JASS Natives List (Work to all war3 versions)

[DarkSupremo]

.mix file:
JassFinder.zip

How to use:
- Just extract it on your war3 folder and start the war3, it will generate instantly an file named Functions.txt on your war3 folder

List generated with it:
http://www.garenamaster.com/war3jass/24b.txt

Thanks to YourName and n00b32 that give me the base to do it...

Just an tip to developers:
I did an class based on it that populate an list with the offset and jass name, with that you can just do an function like CJass->find("CreateUnit") to return the offset of this jass, its really simple and usefull to make hacks to work with every war3 version with no much code ^^

Thank you for this.
I have a simple question about its DataTypes, would be great if you let us know what are the characters that are listed as DataTypes (Return values and Parameters).
I saw, 'S', 'V', 'I', 'R', 'C', 'B', 'Hplayer', 'Hunit', 'Hhandle', ...
So far, i have understood that 'B' is bool, and i know the 'H' before its other DataTypes means a handle to something, but i do not know what DataTypes should i use for them in C++.


Edit: The links you have provided do not work, but the JassFinder itself works perfect.

[YourName]

s -> string
v -> void (If there's a v in parameters it means there is no parameter)
i -> int
r -> float
c -> wat?
b -> bool

Stuff with H are obviously handles as you stated so you need a pointer to a handle class in order to use them.

R = real, but its basically the same as float...

some functions return an "HXXXX" (handle) that you can store it as DWORD and use it in other functions that get the same (HXXXX) as parameter...

this site explain better the parameters, you can find the function on the list and use this site to understand the parameters:
CreateUnit - WarCraft3

Thanks, this helped me so much.

2 more questions:
I found ClearSelection from the list, here it is: "ClearSelection" located at 0x6F3BBAA0 with parameters "()V"
Then, first of all, I declared it this way ( I'm not sure if I'm correct ):

typedef void (__cdecl *GAME_ClearSelection)();
GAME_ClearSelection ClearSelection = (GAME_ClearSelection)(GameDll + 0x3BBAA0);

Finally, I have assigned a HotKey to call the ClearSelection function and I called it this way (!): ClearSelection();
If it's important ( I'm sure it is ), I pressed the HotKey when I was in game and my hero was selected by me.
I don't know what was the problem, but WC3 just crashes each time :|

The second question:
As you said,

Stuff with H are obviously handles as you stated so you need a pointer to a handle class in order to use them.

For example, this one:
"GetLocalPlayer" located at 0x6F3BBB60 with parameters "()Hplayer;"
This should return a handle to the Local player as far as I can guess, am I correct? If Yes, which DataType should I use? I tried DWORD (!) with no success :|

Edit: DS, when I was posting this, you didn't posted yet, thank you, you made it more clear.

---------- Post added at 02:05 AM ---------- Previous post was at 12:40 AM ----------

Just to understand how things are working, let me ask, should this work?

typedef DWORD __cdecl GAME_GetLocalPlayer();
GAME_GetLocalPlayer *GetLocalPlayer = (GAME_GetLocalPlayer *)(GameDll + 0x3BBB60);


typedef string __cdecl GAME_GetPlayerName(DWORD);
GAME_GetPlayerName *GetPlayerName = (GAME_GetPlayerName *)(GameDll + 0x3C0F60);


void ShowName()
{
	DWORD LocalPlayer = GetLocalPlayer();
	string PlayerName = GetPlayerName(LocalPlayer);


	MessageBox(NULL, PlayerName.c_str(), "", MB_OK);
}

[DarkSupremo]

i don't know... i normally do it with inline asm...

[GoDLiKe.ON3]

May i ask for a working example of doing this using inline asm? Just if you have the time for this.
Cause the snippet code on my previous post just fails every time with a fatal error.

[YourName]

That's because the tls isn't set.

[GoDLiKe.ON3]

Sorry, i do not know anything about TLS, any help? What is TLS even?
