A New Dimension for Snake Game: The Object-Oriented Version


Recommended Posts


Sometimes, the most interesting discoveries happen by accident. That's how I stumbled upon an old post presenting a classic version of the game Snake. However, rather than simply appreciating the game as it was, I saw an opportunity for improvement by using AutoItObject.au3 , a powerful tool that didn't exist at the time of the original version's creation. In this article, I'll introduce you to my object-oriented version of Snake Game, which brings flexibility and modernity to this timeless classic.


AutoItObject.au3 is an incredibly flexible tool that allows for modular and efficient application and game development. With this library, I was able to completely rethink the structure of the Snake game, transforming it into a rich and dynamic object-oriented experience. This means that every entity in the game, from the snake to the food to the user interface, is represented as a distinct object, offering extraordinary flexibility and extensibility.


One of the main features of my version of Snake Game is the ability for players to express their own preferences and customize the gaming experience to their liking. Whether adjusting the score, modifying the difficulty level, or adding new game elements, players have the freedom to shape the game to suit their preferences.


Despite its underlying complexity, using AutoItObject.au3 makes the code for Snake Game surprisingly simple and easy to understand. Each game object is carefully encapsulated and modeled to accurately reflect its behavior in the real world. This means that developers can easily add new features or modify the game without compromising its stability or quality.


By reimagining Snake Game through the lens of object-oriented programming with AutoItObject.au3, I was able to create a version of the game that combines the simplicity of the original classic with the flexibility and modernity of object-oriented programming. I look forward to seeing how this version evolves over time, and I hope it inspires other developers to rethink their own projects using this powerful library.

The script doesn't run since you use some unknown script called Print.au3 (at least in the latest AutoIt version). If you comment the line then the script run but the collision doesn't seems to work. Also the flicker is present even when the length of the snake it's just one and get worse when the length increase. Mabye drawing the objects using GDI+ will fix this issue. Overall it's a good start but it leaves room for improvements.

Thank you very much, Andreik, for your constructive feedback. Indeed, the adoption of GDI+ has significantly improved the fluidity of the snake's movements in its eternal quest for food. This major change was accomplished in record time (including a 5-minute coffee break) thanks to the flexibility of the object-oriented paradigm offered by the AutoItObject.au3 UDF. With this tool, you can literally build an empire, brick by brick.

Now, you have the freedom to adjust the snake's speed, change its color on the fly, even during gameplay, and even generate fake prey of different colors to try to trap "Kaa," Mowgli's old companion. In other words, you can unleash your imagination and push the boundaries of what's possible.

  1. Initialization:

    • Upon starting the game, a game window titled "Snake" is created with dimensions of 400x400 pixels.
    • The snake and food objects are initialized, and the game environment is set up.
  2. Game Loop:

    • The game runs in a continuous loop until the user closes the window.
    • During each iteration of the loop, the game performs the following actions:
  3. Snake Movement:

    • The snake automatically moves in the direction indicated by the arrow keys (up, down, left, or right).
    • The snake's movement speed is determined by the speedLevel property, which decreases as the snake eats more food.
  4. User Input:

    • The user can control the snake's direction using the arrow keys:
      • Up arrow: Move the snake upwards.
      • Down arrow: Move the snake downwards.
      • Left arrow: Move the snake to the left.
      • Right arrow: Move the snake to the right.
    • Pressing the 'S' key pauses the game until another arrow key is pressed.
  5. Food Generation:

    • Normal food items and poisoned food items are randomly generated on the game board.
    • Normal food items are represented by green rectangles, while poisoned food items are represented by red rectangles.
    • Normal food increases the snake's length and speed when eaten, while poisoned food triggers a warning message and restarts the game when eaten.
  6. Collision Detection:

    • The game checks for collisions between the snake and various elements:
      • Collision with the edges of the game board: Ends the game and prompts the user to restart.
      • Collision with itself (i.e., when the snake's head intersects with its body segments): Ends the game and prompts the user to restart.
      • Collision with food items: Determines whether the food is normal or poisoned, and adjusts the game accordingly.
  7. Game Over:

    • When a collision occurs, a message box appears indicating the cause of the collision (e.g., collision with the edge of the board or with the snake itself).
    • The user is given the option to restart the game or exit.
  8. Game Restart:

    • If the user chooses to restart the game, the game environment is reset, and a new game begins.
    • The snake's length, speed, and other parameters are reset to their initial values.
  9. Graphics:

    • The game board and its elements (snake segments and food items) are drawn using GDI+ graphics.
    • The graphics are refreshed continuously to reflect changes in the game state.

In summary, the game progresses as the snake moves around the board, eating food items and avoiding collisions. The objective is to survive as long as possible without colliding with obstacles. The game provides a challenging and entertaining experience for players.

 

Dependencies:

  • AutoItObject.au3: This script is essential for enabling object-oriented programming (OOP) in AutoIt. It allows the creation of custom classes, properties, and methods, which are utilized extensively in the Snake game implementation.
  • LinkedList.au3: This script provides the LinkedList data structure, which is used to manage the segments of the snake's body and the food items on the game board efficiently.

LinkedList Usage:

  • Managing Snake Segments: The LinkedList data structure is used to store the segments of the snake's body. Each segment is represented as an object with properties for its position (X and Y coordinates). The LinkedList allows easy addition, removal, and traversal of these segments.
  • Managing Food Items: Similarly, the LinkedList is utilized to manage the food items on the game board. Each food item is represented as an object with properties for its position and type (normal or poisoned). The LinkedList enables dynamic addition and removal of food items during the game.
  • Efficient Data Management: By using a LinkedList to store the snake segments and food items, the game can efficiently handle dynamic changes in the number of segments and food items. This data structure provides flexibility and scalability, allowing the game to adapt to different scenarios and game states.

When the snake is long enough the chance of food being spawn under the snake it's pretty high. It would be a good idea to check if the location where the food is spawn it's an empty space. Also it's very hard to eat a poison food (even if you want) if it's randomly spawn and the duration of being displayed it's so short. It would be more interesting if the food stays longer or if the poison food it's spawned in the proximity of the snake.

I have taken note of your valuable suggestion. What do you think about this idea? : instead of making poisoned food appear, I thought about making a speed reducer appear to give the player more luck. What do you think ?

Final version: I wanted to demonstrate the constant evolution of this code since its inception to highlight the ease of use of object-oriented programming in AutoItObject.au3, in addition to the remarkable power already provided by AutoIt. This combination forms a single entity: maximum power. So, I effortlessly introduced a new feature in the game: a speed reducer, where the snake must do everything to swallow it in order to slightly slow down and catch its breath. You'll notice that adding new features doesn't affect the structure of the code, which remains easy to maintain. That's the magic of AutoItObject. I encourage you to explore this aspect in depth. You are free to develop this game, whose code is clean, modular, and easy to design and maintain.
