Ok, well i got a fps camera, which works and basically plots a single model on vector3.zero, so i changed it to allot me to change the spots of this models in way like new vector3(0.0f, 50.0f, 20.0f,) but when i change it to allow that the contotrls dont work, only escape does. Below is my code, it must be simple what im doing wrong :S using System; using System.Collections.Generic; using Microsoft.Xna.Framework; using Microsoft.Xna.Framework.Audio; using Microsoft.Xna.Framework.Content; using Microsoft.Xna.Framework.GamerServices; using Microsoft.Xna.Framework.Graphics; using Microsoft.Xna.Framework.Input; using Microsoft.Xna.Framework.Net; using Microsoft.Xna.Framework.Storage; namespace CameraDemo { /// <summary> /// This is the main type for your game /// </summary> public class Game1 : Microsoft.Xna.Framework.Game { GraphicsDeviceManager graphics; SpriteBatch spriteBatch; Vector3 cameraPosition; Vector3 cameraTarget; Vector3 cameraReference; float aspectRatio; float nearPlane; float farPlane; float fieldOfView; Matrix Projection; float cameraYaw; float cameraPitch; MouseState mStateCashe; Vector3 modelPosition; //TEST CODE START GameObject crate = new GameObject(); //TEST CODE END public Game1() { graphics = new GraphicsDeviceManager(this); Content.RootDirectory = "Content"; } /// <summary> /// Allows the game to perform any initialization it needs to before starting to run. /// This is where it can query for any required services and load any non-graphic /// related content.
