copied!<p>I didn't use XNA, but I did some Managed C# DX long time ago, so I don't remember too much, but are you sure <code>mirrorLookAt</code> should point to a cameraFinalTarget? Because basically the <code>Matrix.CreateLookAt</code> should create a matrix out of from-to-up vectors - 'to' in your example is a point where mirror aims. You need to calculate a vector from camera position to mirror position and then reflect it, and I don't see that in your code.</p> <p>Unless your <code>room.DrawRoom</code> method doesn't calculate another <code>mirrorLookAt</code> matrix, I'm pretty sure your mirror target vector is the problem.</p> <p><strong>edit:</strong> Your reflection vector would be</p> <pre><code>Vector3 vectorToMirror = new Vector3(mirrorPos.X-camera.position.Y, mirrorPos.Y-camera.position.Y, mirrorPos.Z-camera.position.Z); Vector3 mirrorReflectionVector = new Vector3(vectorToMirror-2*(Vector3.Dot(vectorToMirror, mirrorNormal)) * mirrorNormal); </code></pre> <p>Also I don't remember if the mirrorReflectionVector shouldn't be inverted (whether it is pointing to mirror or from mirror). Just check both ways and you'll see. Then you create your <code>mirrorLookAt</code> from</p> <pre><code>Matrix mirrorLookAt = Matrix.CreateLookAt(mirrorPos, mirrorReflectionVector, Vector3.Up); </code></pre> <p>Though I don't know wher the normal of your mirror is. Also, I've noticed 1 line I can't really understand</p> <pre><code>if (camera.isCrouched) camerafinalPosition.Y -= (camera.characterOffset.Y * 6 / 20); </code></pre> <p>What's the point of that? Let's assume your camera is crouched - shouldn't its Y value be lowered already? I don't know how do you render your main camera, but look at the mirror's rendering position - it's way lower than your main eye. I don't know how do you use your <code>IsCrouched</code> member, but If you want to lower the camera just write yourself a method <code>Crouch()</code> or anything similar, that would lower the Y value a little. Later on you're using your <code>DrawRoom</code> method, in which you pass <code>camera.position</code> parameter - yet, it's not "lowered" by crouch value, it's just "pure" camera.position. That may be the reason it's not rendering properly. Let me know If that helped you anything.</p>
