How can I make a game like doodlejump XNA c#
- by Ramy
I wanted to know how can I make the background scroll down like doodlejump. I have a game made and I have to transform it so it's like doodle jump, but I'm wonder how or where to look so I can make he background keep moving as in progressing through the background till let's say the character dies.
namespace IFM20884
{
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Content;
using Microsoft.Xna.Framework.Graphics;
public abstract class BackgroundScroll : Sprite
{
private float speedOfBackground = 0.2f; // speed that the background moves
public BackgroundScroll (GraphicsDeviceManager graphics)
: base(graphics.GraphicsDevice.Viewport.Width / 2f, graphics.GraphicsDevice.Viewport.Height / 2f)
{
}
//Getter
public float speedOfBackground
{
get { return this.speedOfBackground ; }
set { this.speedOfBackground = value; }
}
public override void Update(GameTime gameTime, GraphicsDeviceManager graphics)
{
//Makes background go down.
ForcePosition(Position.X, Position.Y + (gameTime.ElapsedGameTime.Milliseconds * this.speedOfBackground ));
if (Position.Y - (Height / 2) > graphics.GraphicsDevice.Viewport.Height)
{
ForcePosition(Position.X, Position.Y - this.Height);
}
}
public override void Draw(SpriteBatch spriteBatch)
{
ForcePosition(Position.X, Position.Y - this.Height);
base.Draw(spriteBatch);
ForcerPosition(Position.X, Position.Y + this.Height);
base.Draw(spriteBatch);
}
}
}
