Planning the project

• First steps:

– Finding fellows

– Finding ideas

– Finding an appropriate programming language

Problems during programming

• Collisions:

Problems during programming

• Variety of projectiles

• Moving tank across level

Problems during programming

• Background

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…

Tank movement: requirements

• The tank‘s x position

Tank movement: requirements

• Ground level at given x position

Tank movement: requirements

• Fixed reference points

New x position

• Check if new tank angle is legal: Yes move tank to this position, decrease remaining move distance for this turnNo do not move tank

• …done
