Ghost Land

About

Real life shooter game. The goal of the game is to shoot as many ghosts before they reach the house.

The game scene is projected on the wall, and a ball is used to shoot. The ball is tracked using a kinect. The collision point of the ball with the wall is the shot.

Video here.

Aim

The aim of the game is to improve hand-eye coordination and provide a fun way to exercise.

Technologies

The challange was to build an "alive" game using the benefits of modern technologies like:

• projector/beamer
• Kinect
• Processing
• WebSockets
• Phaser

Requirements

• Kinect (first generation)
• Processing 2.x
  • SimpleOpenNi
  • websocketP5
  • blobscanner
• Google Chrome 45
• Phaser 2.4.3

How it works

1. Open the web page in browser and project it on the wall

• Run the processing sketch
• In opened window click on the corners of projected image. Corners order is top-left, top-right, bottom-right, bottom-left
• A rectangle should appear. It means that depth image processing started
• Focus on browser (Phaser stops if it is not focused). If game music is playing then everything is ok.
• Throw the ball to the wall
• Have fun!

Technical problems that still have to be solved

• Collision point is not perfect. Right now it is computed by taking the fartherst detected point. A better approach would be to compute ball trajectory and get the intersetion with the wall
• Projected points are not perfectly matched with game rectangle. You can see in video (borrom-right corner) that red circle (collision point detected by Kinect) and white circle (point in game) are shifted. A affine transformation should solve this problem much better.
