What is this?

This is a very simple DLL library that acts like a wrapper for NPClient64.dll (64bit version), which is a client library for TrackIR software.

Purpose

The only purpose of this wrapper for now is to modify the values for NP_GetData() so it's possible to modify values requested from TrackIR before they are passed to the game.

This achieves a single purpose of changing the default angles when you recenter your TrackIR and is particularly useful for games that don't allow to set camera angles that are then honored with TrackIR turned on, namely Falcon 4 BMS.

And this solution works properly with the TrackIR configured deadzone.

Installation

Due to the fact that the client library resides in the TrackIR software installation directory and most games load them from there by a full path the only method to install this wrapper is globally.

1. Find a directory where TrackIR software is installed. This will most probably be: "C:\Program Files (x86)\NaturalPoint\TrackIR5" or something similar.
2. Rename the client library that is there:

NPClient64.dll -> NPClient64-orig.dll

3. Extract the downloaded file (np-wrapper-VERSION.zip) and put the wrapper library NPClient64.dll and the config file NPWrapper.ini inside the TrackIR installation directory. Ignore the debug directory from the zip.

• Make sure you rename first so you won't overwrite!
• Make sure to rename exactly to the filename above! This is not just for backup. The original library is still required.
• Reinstallation or update of the TrackIR software necessitates reinstall of the wrapper as the original libraries will be put in place.

Configuration

The NPWrapper.ini is a config file. This is a very simple file, no comments, no sections, one line per game.

TRACK_IR_GAME_ID ROLL_SHIFT PITCH_SHIFT YAW_SHIFT

The provided config has a line for BMS that shifts the pitch camera angle 5 degrees down.

Negative and float values are acceptable.

Further remarks

This has been ONLY tested with:

• TrackIR 4 hardware (although it shouldn't matter)
• TrackIR 5.4.2 software (recently released 5.5 doesn't work for me)
• Falcon 4 BMS game
• only the 64bit library

If you want to add configuration for other games you need to know TrackIR game ID for them. An easy way is to use a debug version of this library and check the log file (C:\Users\USERNAME\NPWrapper64.txt).
