Basic functions

Part 1 - Gameplay











  • a. Must have at least 3 levels
    For the game play, we designed 3 levels which are composed of different kind of enemies.
      - Level 1: Only normal goblins
      - Level 2: Normal goblins and elite goblins
      - Level 3: Normal goblins, elite goblins and Boss goblins


Code 
    public static InitConfig SharedInstance;
    // Define board size
    public const int BoardWidth = 16;
    public const int BoardHeight = 20;
    // Define cannon type
    public const int CannonType1 = 101;
    public const int CannonType2 = 102;
    public const int CannonType3 = 103;
    // Define enemy number for each level
    public Dictionary<string, int> enemyCount;
    // Define base cost to build cannon
    public const int BaseCost = 50;

    public const string TagObstacle = "Obstacle";
    // Define current game level
    public int gameLevel = 1;
    // Define current selected cannon type
    public int CANNON_TYPE = 0;
    public int DifficultLevel = 1;
    // Score, or money gained by kill enemy
    public int score;
    // Number of enemy passed
    public int passCount;

    private int Level1Enemy1, Level2Enemy1, Level3Enemy1, Level2Enemy2, Level3Enemy2, Level3Enemy3;
  • b. can also add an option to ‘speed up’ the game

we designed the UI for speed control and implemented the according function with Time.timeScale



Code

Handle piece click

    public void SpeedUp()
    {
        speed++;
        timeScale = 1 + speed * 0.3f;
        MeshProSpeed.text = (speed + 4).ToString();
        Time.timeScale = timeScale;
    }
    
    public void SpeedDown()
    {
        if(0.3 * (speed - 1) < -1)
            return;
        speed--;
        timeScale = 1 + speed * 0.3f;
        MeshProSpeed.text = (speed + 4).ToString();
        Time.timeScale = timeScale;
    }
  • c. Learning curve – game should be easy to start and learn.
    Quite easy for starters, since this game is designed for mobile phone and only have a few buttons. Specifically, we only have 4 buttons in the main UI, and 4 buttons in the submenu when you press Esc.
    Also, we implemented some hint for new players, in order to provide a better gameplay.


Part 2 - Look and feel

  • Graphics and animation – game must be 3D and animated
    Please check our video demo or application for more details.


  • Sound – game must have sound, including some type of theme music
    Please check our video demo or application for more details.
  • The graphics, animation, sound, etc., should all match the theme of your game.
    Please check our video demo or application for more details.

Part 3 - Controls and UI

  • Game must be designed with mobile gameplay in mind
    To work properly on mobile phone, we designed our game with only 4 main buttons, which is convenient for moible users, since the screen size of mobile devices are limited(no more than 7 inches for most cases). Also, we implemented the scene based on landscape, which will make full use of mobile screen.

  • Main menu with at least the following 4 buttons:



  • The in-game UI should be intuitive (player can figure out what a button does by the button’s icon)
