basic incomplete code for the logic of a heat seeking rocket projectile.

    end
    if found_monster then break end
  end
  if not found_monster then
    --if no monster was within sensor range, just go straight
    continue_course()
  end

end

function set_kill_course(destination)
  --modifies the trajectory of the rocket to match its target
  
end

function continue_course()
  --continue trajectory in straight path to its inevitable doom
end

function collision()
  --check to see if rocket has collided with anything like a wall, monster, or npc
end

function asplode()
  -- explode and die/delete object
end
