3d -> 2d Positions. Almost......

I've searched and found nfo on DGLPointtoscreen... and the Project and Unproject. I've tried for a few hours to get any of these to work to no avail, i've got it to return strange values.. but clearly not what they should be.
So i need someone to hold my hand and help me.
i want to feed a function XYZ coords an get XY back so i can use it to position a GUI target indicator. When i tried to make my own console functions i ran into issues of variable mismatches and other confusing stuff. I'm no C++ expert so it's easy for me to not know what i'm doing. I wanted to research Project() a little more.. but it's impossible to search for that on the site... since it doesn't include the ().
So... can anyone help me by providing a link to something that may help me? or perhaps someone can provide the actual code?

Have you looked at how the names are displayed above the characters? That is a GUI text displayed for a 3D location. Thats why the name always displays the same size and is always correctly rotated.

no where in the c++ do i have it setting the mTargeted value.. yet it's getting both false and true on different loops.
few printfs from my console.
..............
targeted
not a target
not a target
targeted
not a target
..........
using a console method to set the value doesn't seem to change how this this is working.
so i'm having a hard time getting this.

GuiShapeNameHud. I've spent all night in it tyring to modify it for what i need. but for some reason i can't seem to figure out how to make new variable for my shapebases that it will understand. I've added a new one called mTargeted. and a couple console methods to set and get the values. everything seems ok. but the GuiShapeHud is calling the same function i call from torque script and it's not getting the same values. infact it's nuts. no where in the c++ do i have it setting the mTargeted value.. yet it's getting both false and true on different loops.

and the call to it in the Gui script
it's echoing out back and forth that it's true then false or what not.

Here's the section of where it's retreiving the variable.bool ShapeBase::getTargeted()
{
if (mTargeted){
Con::printf("targeted");
return true;
}
else if(!mTargeted){
Con::printf("not a target");
return false;
}
else
return false;
}and the call to it in the Gui script
if (shape->getTargeted()) {it's echoing out back and forth that it's true then false or what not.

Are you networking mTargeted properly?
