  1. Games to Science Runo Marian, Oppliger Andreas, Neff Marius, Hirt Luca Project „Tankwar“ by

  2. Games to Science - Presentation • Introduction • Planning • Problems • Solving problems (Implementations) • Demonstration • Questions

  3. Planning the project • First steps: • Finding fellows • Finding ideas • Finding an appropriate programming language

  4. Problems during programming • Collisions:

  5. Problems during programming • Variety of projectiles

  6. Problems during programming • Moving tank across level

  7. Problems during programming • Background

  8. Tank movement The Tank.move(int d) function makes the tank move d pixels to the right, if possible. The tank‘s angle is automatically adjusted according to the landscape. Implementation overview follows…

  9. Tank movement: requirements • The tank‘s x position

  10. Tank movement: requirements • Ground level at given x position

  11. Tank movement: requirements • Fixed reference points

  12. New x position

  13. Check if new tank angle is legal: Yes  move tank to this position, decrease remaining move distance for this turn No  do not move tank • …done

  14. Graphic Definition of the landscape in the XML-file <color value="cyan"> <fillRect x="0" y="0" dx="1000" dy="500"/> </color> <color value="green"> <fillRect x="0" y="450" dx="1000" dy="200"/> <fillOval x="100" y="400" dx="500" dy="200"/> <fillOval x="400" y="400" dx="500" dy="200"/> <fillOval x="300" y="220" dx="400" dy="600"/> <fillOval x="250" y="308" dx="100" dy="100"/> <fillOval x="650" y="308" dx="100" dy="100"/> </color> <color value="cyan"> <fillOval x="-47" y="292" dx="200" dy="200"/> <fillOval x="847" y="292" dx="200" dy="200"/> <fillOval x="150" y="208" dx="200" dy="200"/> <fillOval x="650" y="208" dx="200" dy="200"/> </color>

  15. Projectile collision detection • Landscape image mask • Adding tanks • Per pixel check • Explosion initiation

  16. Demo
