Mumble Audio positional plugin

[blacktwister]

Hi,

I try to make mumble audio positional plugin with this tutorial (https://wiki.mumble.info/wiki/Pluginguide#Tools_Needed) for the game Mount and Blade Warband.

I have found adresse : https://gyazo.com/f9552ddf1d6d57bdcc449ca77b4019af?token=8e8e4fa1d5f1d1c10fbec3f2aae5b3cc

and this is my code

for (int i=0;i<3;i++) {
	avatar_pos[i] = avatar_front[i] = avatar_top[i] = camera_pos[i] = camera_front[i] = camera_top[i] = 0.0f;
}

// Boolean values to check if game addresses retrieval is successful and if the player is in-game
       bool ok, state;
       // Create containers to stuff our raw data into, so we can convert it to Mumble's coordinate system
float avatar_pos_corrector[3], avatar_front_corrector[3], avatar_top_corrector[3];

// Peekproc and assign game addresses to our containers, so we can retrieve positional data
ok = peekProc(pModule + 0xA625AC, &state, 1) && // Magical state value: 1 when in-game and 0 when in main menu.
	peekProc(pModule + 0x1D99484, avatar_pos_corrector, 12) && // Avatar Position values (X, Z and Y, respectively).
	peekProc(pModule + 0xDD8A64, avatar_front_corrector, 12) && // Avatar Front Vector values (X, Z and Y, respectively).
	peekProc(pModule + 0xA6293C, avatar_top_corrector, 12); // Avatar Top Vector values (X, Z and Y, respectively).

// This prevents the plugin from linking to the game in case something goes wrong during values retrieval from memory addresses.
if (! ok) {
	return false;
}

I compile with the visual microsoft studio 2010 express, with win32 header, its ok no error, i take the .dll file, i put it in my plugin folder. I launch mumble 1.2.xx , the game. Mumble detect the game, but in my PAHelper receive nothing, all values are in 0, and the plugin doesnt work :/ (i have activate all options for positional audio but apparently the problem is : the plugin doesnt work, he send nothing to mumble :/ no value for position, front or top vector... but adresse are apparently good...)

Do you have an idea for help me ?

Hi,

The value of state is probably false, set it to true.
