3DConnexion 3D mouse

[mtrx]

Hello, fellow devs
Ive made a little dll for my thesis, so i though i shared it with you(i wanted to see if it works on other 3DConnexion mice).
http://matrix-bf.ic.cz/dll/DI3dCnnxn.dll (i hope the site doesnt crash, suggest alternative sites though)
put it in your UDK/Binaries/Win32/UserCode

This dll uses directInput, so it should work without driver of the mouse.
DLL polls the mouse, so if your fps goes down, you probably get too sensitive input.
Buttons arent supported yet, so you will have to use 3Dx drivers for getting button presses.

Heres UScript Code
In your gameinfo:

class YourGame extends UTGame;

DefaultProperties
{
  PlayerControllerClass = class'YourProject.YourPlayerController'
}

In your controller:

class YourPlayerController extends UTPlayerController;

DefaultProperties
{
  InputClass=class'YourProject.YourPlayerInput'
}

In your playerInput

class YourPlayerInput extends UDKPlayerInput within YourPlayerController
	DLLBind(DI3dCnnxn);

//these are not necessary, i added them for my project
var input float aPitch;
var input float aYaw;
var input float aRoll;

var	float	PitchRotationSpeed;
var	float	YawRotationSpeed;
var	float	RollRotationSpeed;
