Haha awesome.

I've always been meaning to sort out the WorldToScreen stuff. Looks like I need to do a bit of a refresher on matrix math...

I don't think it's anything on his part really, just using D3D functions. Surely there's a function in the API that draws a 3D line :P

EDIT: On second thought, nevermind.

You need to do your own WorldToScreen stuff.

You need to do your own WorldToScreen stuff.

You don't have to. If you can find WoW's matrices and whatnot, you can just use D3D to unproject it.

Okay, well at any rate, you can't just use D3D's built in transformation functions without doing a lot of extra work.

My point was that extra work is required, how you choose to do that work is another story entirely as there are several alternatives.

It wouldn't be too much work..

public static Vector2 WorldToScreen(Vector3 world)
{
   Vector3 Project = GraphicsDevice.Viewport.Project(world, Projection, View, Matrix.Identity);

   // Check our Z, otherwise return a huge Vector off-screen because I'm Lazy.
   if (Project.Z < 1.0f)
      return new Vector2((float)Math.Floor(Project.X), (float)Math.Floor(Project.Y));
   else
      return new Vector2(GraphicsDevice.Viewport.Width * 4, GraphicsDevice.Viewport.Height * 4);
}

Now all you need to create the Projection and View matrices is the Camera Position, your 'Target' Position (which can be easily calculated), Your FieldOfView (90?), and Aspect ratio.

That leaves you really with only Two things you need to find (Camera position/Camera Angle or 'Target' Position), because the rest can be calculated or found with simpler methods.

Then all you would have to do to create the matrices is a couple lines of code.

float AspectRatio = GraphicsDevice.Viewport.Width / GraphicsDevice.Viewport.Height;

Matrix View = Matrix.CreateLookAt(CameraPosition, Target, Vector.Up);
Matrix Projection = Matrix.CreatePerspectiveFieldOfView(90.0f, AspectRatio, 0.01f, 8192.0f);

Simple. Easy. Plus it works.

What Matrix library do you recommend for simple things like this? Custom?

Old code, new face!

Bots using waypoint graphs instead of the more advanced polygons mesh suffer badly from the "on rails"-syndrome though

Edit: Looks like the embedded version doesn't have the audio removed. How awesome. Watch in HD!
Edit2: Nvm they deleted the music. Hf with this -,-

Very cool!

[paradoxial]

Looks nice Robske.

[complxor]

very nice robske, looks amazing

The yellow is the WMO (Orgrimmar in this case)

The pink is our nav mesh. And yes; pathfinding works.

Omg , i'm , i'm ...ahhhh *crying*

Apoc that is awesome! Keep up the good work

That is SO hawt.
