1. Tutorial 14

• during this tutorial we will
  • understand the PGE API
  • create a small pinball game using PGE
  • understand how PGE integrates with PyGame

2. Using PGE to create a game

• full documentation about PGE is available

3. Creating a pinball game using PGE

• start with the breakout game source code and adapt it
• throw away all the blue boxes and associated callbacks
• see that the modified game still runs to completion

4. Pinball

• add some extra circles and maybe modify the triangles (smaller possibly)
• add a score so that every time the ball hits a triangle you gain +20 points
  • every time it hits a particular circle it gains +10 points
• every time the points increase by a 100 an extra life should be granted
• allow the user to fire a new pinball when the old pinball is lost
  • decrease the life count as a pinball is released
• add a firing shoot for the pinball
  • allow the user to aim the ball with the mouse

5. Pinball flippers

• PGE is not capable of rotating objects, so you will have to think creatively to implement a way of ‘‘interfering’’ with the pinball
• you could adjust the x movement of the ball slightly if the left/right mouse button was pressed
• or you might introduce a fixed polygon (representing the flipper) as a paddle (aka breakout)
  • the polygon could be deleted and moved upon mouse movement
  • be careful and ensure that the polygon resides along a, y = constant, line
• what simple changes would you make to the API to create a simple flipper?

6. Conclusion

• we have
  • understood more about the PGE API
  • created a small pinball game using PGE
  • understood how PGE integrates with PyGame
• you might want to read around the subject by reading this paper The Construction of a Predictive Collision 2D Game Engine
