// My new attack program.
// Aiming and enemy seeking has been improved.
// It works with all shooters (legged, winged, etc.)
// against all enemy races (ant, wasp, etc.).
// Because there is a bug with pitch value not being
// recognized correctly while in 1st-person camera view,
// I recommend switching camera view to 3rd-person for best
// results.  Happy Hunting!
