Implementing the finite state machine
Creating the Tank Enemy
The tank enemy consists of the tank's graphics as well as the tank's artificial intelligence.
Creating the Tank Graphic
The graphics for the tank are two pyramid-shaped polygons. The lower polygon representing the
tank body is identical to the top polygon representing the tank's turret, except for being slightly
larger.
The Pyramid2 class holds the data for the tank body and tank turret in the
Pyramid2Vertices
array
Listing 8-8.)
