How to: Tint a Sprite
This article demonstrates how to tint a sprite using a Color value.
To draw a tinted sprite on screen
Follow steps 1–4 of How to: Draw a Sprite.
In the Update method, determine how to tint the sprite. In this example, we take the value of the game pad thumbsticks and determine Red, Green, Blue, and Alpha values to apply to the sprite.
protected Color tint;
protected override void Update( GameTime gameTime ) { ... // TODO: Add your update logic here. GamePadState input = GamePad.GetState( PlayerIndex.One ); tint = new Color( GetColor( input.ThumbSticks.Left.X ), GetColor( input.ThumbSticks.Left.Y ), GetColor( input.ThumbSticks.Right.X ), GetColor( input.ThumbSticks.Right.Y ) );
base.Update( gameTime );
}
In the Draw method, pass the color value created in Update to SpriteBatch.Draw.
protected override void Draw( GameTime gameTime )
{ graphics.GraphicsDevice.Clear( Color.CornflowerBlue );
// TODO: Add your drawing code here.
ForegroundBatch.Begin();
ForegroundBatch.Draw( SpriteTexture, position, tint );
ForegroundBatch.End();
base.Draw( gameTime );
}
- When all of the sprites have been drawn, call End on your SpriteBatch object.
