Tankwar: A Journey Through Game Development and Problem Solving

Dive into the world of game development with "Tankwar," a project by Games to Science. This presentation covers the project's journey from planning and idea generation to programming challenges and their solutions. Explore key topics like tank movement mechanics, projectile collision detection, and landscape definition. Gain insights into the immersive process of creating a game, including overcoming technical hurdles and implementing a responsive gaming environment. Play the game, provide feedback, and discover the underlying code driving "Tankwar."

  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
