Here's the issue, When I build, everything loads fine, everything works, but then, when you enter the game, the sprite is there. However, The sprite does not move, the sprite RECTANGLE does. Meaning that, if I used my arrow keys to move the "sprite", as I defined them in the update method of my class, the rectangle would move freely, and cut off parts of the sprite. If I moved it the right far enough, the rectangle would leave the sprite, and the sprite will disappear.
Here's a picture of what it looks like:
and another when I use my arrow keys to move:
Here is the code from my sprite class:
class Player : Sprite { const string PLAYER_ASSETNAME = "CharacterLeft"; const int START_POSITION_X = 125; const int START_POSITION_Y = 245; const int WIZARD_SPEED = 160; const int MOVE_UP = -1; const int MOVE_DOWN = 1; const int MOVE_LEFT = -1; const int MOVE_RIGHT = 1; enum State { Walking } State mCurrentState = State.Walking; Vector2 mDirection = Vector2.Zero; Vector2 mSpeed = Vector2.Zero; KeyboardState mPreviousKeyboardState; public void LoadContent(ContentManager theContentManager) { Position = new Vector2(START_POSITION_X, START_POSITION_Y); base.LoadContent(theContentManager, PLAYER_ASSETNAME); } public void Update(GameTime theGameTime) { KeyboardState aCurrentKeyboardState = Keyboard.GetState(); UpdateMovement(aCurrentKeyboardState); mPreviousKeyboardState = aCurrentKeyboardState; base.Update(theGameTime, mSpeed, mDirection); } private void UpdateMovement(KeyboardState aCurrentKeyboardState) { if (mCurrentState == State.Walking) { mSpeed = Vector2.Zero; mDirection = Vector2.Zero; if (aCurrentKeyboardState.IsKeyDown(Keys.Left) == true) { mSpeed.X = WIZARD_SPEED; mDirection.X = MOVE_LEFT; } else if (aCurrentKeyboardState.IsKeyDown(Keys.Right) == true) { mSpeed.X = WIZARD_SPEED; mDirection.X = MOVE_RIGHT; } if (aCurrentKeyboardState.IsKeyDown(Keys.Up) == true) { mSpeed.Y = WIZARD_SPEED; mDirection.Y = MOVE_UP; } else if (aCurrentKeyboardState.IsKeyDown(Keys.Down) == true) { mSpeed.Y = WIZARD_SPEED; mDirection.Y = MOVE_DOWN; } } } } }
and here's the code to my main sprite class:
class Sprite { //The asset name for the Sprite's Texture public string AssetName; //The Size of the Sprite (with scale applied) public Rectangle Size; //The amount to increase/decrease the size of the original sprite. private float mScale = 1.0f; //The current position of the Sprite public Vector2 Position = new Vector2(0, 0); //The texture object used when drawing the sprite private Texture2D mSpriteTexture; //The player Rectangle private Rectangle SpriteRect; //Load the texture for the sprite using the Content Pipeline public void LoadContent(ContentManager theContentManager, string theAssetName) { mSpriteTexture = theContentManager.Load<Texture2D>(theAssetName); AssetName = theAssetName; Size = new Rectangle(0, 0, (int)(mSpriteTexture.Width * mScale), (int)(mSpriteTexture.Height * mScale)); } //Draw the sprite to the screen public void Draw(SpriteBatch theSpriteBatch) { SpriteRect = new Rectangle((int)Position.X, (int)Position.Y, mSpriteTexture.Width, mSpriteTexture.Height); theSpriteBatch.Draw(mSpriteTexture, Position,SpriteRect, Color.White, 0.0f, Vector2.UnitX, 1f, SpriteEffects.None, 0); } public void Update(GameTime theGameTime, Vector2 theSpeed, Vector2 theDirection) { Position += theDirection * theSpeed * (float)theGameTime.ElapsedGameTime.TotalSeconds; } //When the scale is modified throught he property, the Size of the //sprite is recalculated with the new scale applied. public float Scale { get { return mScale; } set { mScale = value; //Recalculate the Size of the Sprite with the new scale Size = new Rectangle(0, 0, (int)(mSpriteTexture.Width * Scale), (int)(mSpriteTexture.Height * Scale)); } } } }
