I found a Mouse Script, But I need it converted. (RGSS conversion)

[CherryWolf]

Hi, I don't know if this is possible, but I found this script, that looked swell.

{
var mm,dX,dY,dZ,uX,uY,uZ,vX,vY,vZ,mX,mY,mZ, width, height, tFOV;
dX = argument3-argument0;
dY = argument4-argument1;
dZ = argument5-argument2;
mm = sqrt(dX*dX+dY*dY+dZ*dZ);
dX /= mm;
dY /= mm;
dZ /= mm;
uX = argument6;
uY = argument7;
uZ = argument8;
mm = uX*dX+uY*dY+uZ*dZ;
uX -= mm*dX;
uY -= mm*dY;
uZ -= mm*dZ
mm = sqrt(uX*uX+uY*uY+uZ*uZ);
uX /= mm;
uY /= mm;
uZ /= mm;
// v = u x d
vX = uY*dZ-dY*uZ;
vY = uZ*dX-dZ*uX;
vZ = uX*dY-dX*uY;
tFOV = tan(argument9*pi/360);
uX *= tFOV;
uY *= tFOV;
uZ *= tFOV;
vX *= tFOV*argument10;
vY *= tFOV*argument10;
vZ *= tFOV*argument10;
width = window_get_width();
height = window_get_height();
mX = dX+uX*(1-2*mouse_y/height)+vX*(2*mouse_x/width-1);
mY = dY+uY*(1-2*mouse_y/height)+vY*(2*mouse_x/width-1);
mZ = dZ+uZ*(1-2*mouse_y/height)+vZ*(2*mouse_x/width-1);
mm = sqrt(mX*mX+mY*mY+mZ*mZ);
global.mouse_dx = mX/mm;
global.mouse_dy = mY/mm;
global.mouse_dz = mZ/mm;
}

Is it possible to convert this to RGSS(2?)
Its a Mouse system.
(If this is placed wrong, please move it. I couldn't find the right spot to place it  :dead

There's little clue on what this script does.  It apparently takes 10 arguments ("argument1", "argument2", etc.) but there is no clue on what they do.

The result appears to be saved in "global.mouse_dx", "global.mouse_dy", and "global.mouse_dz".  I would guess that they are the 3D position of the mouse on the screen.

The call "window_get_width()" corresponds to 640 in RGSS, and "Graphics.width" in RGSS 2.
The call "window_get_height()" corresponds to 480 in RGSS, and "Graphics.height" in RGSS 2.

"mouse_x" and "mouse_y" refer to the mouse's current position on the game window.

And that's all I can guess about the script.  Without any details on the arguments, however, the script is useless.
