[Android mobile games] Snake (1)

[Android mobile games] Snake
Introduction

I have been learning about android mobile app development, reading books, coding, forums (mainly www.eoeandroid.com), posting, replying, and accumulating a little experience a month ago, familiar with some of the most basic control usage and basic android development ideas.
I have posted several posts on the eoe forum, including [large release and continuous update of demo sets such as basic controls and basic animation effects ], [Sina Weibo open platform development-simple android client], [Examples of novice projects-Notepad] and other demo small examples.
Recently, I want to go through a "snake" game to fully understand the game development process and technical points used.
 
Game Development Process

After a period of study, I think the game development process includes:
Game Planning
Game resource preparation
Game Framework Design
Game Development
Game Testing
Game release
Game upgrade
 
Game Planning
The first thing we need to do is game planning, which is like researching the needs in software development, organizing the needs, and organizing the needs. Design a game, design a game type, scenario, background, game process, specification, and rules.
 
[Snake] Game Planning
1. There are three screens. The score is displayed in the above column. The middle column is the activity area of the snake, and the following column is the operation column, which includes two operation buttons.
2. After the game starts, a upward snake appears below the screen.
3. The left and right keys in the bottom column of the screen can be used to control the snake. The left-click control controls the rotation of the Snake Head 90 degrees to the left, and the right-click control measures the rotation of the Snake Head 90 degrees to the right.
4. An apple appears randomly in the activity area of the snake on the screen. If you eat an apple, the other one will appear.
5. When a snake uses its head to touch a random Apple, the score is + 10. The speed increases as appropriate.
6. If the snake's head touches the boundary of the active area, the snake will randomly turn to the left or right to 90 degrees.
7. If the snake's head touches the body, the game ends. After the game ends, you can enter the user name to record the score.
8. The ranking function is available to show users and scores in the ranking.
8. The game is a pass-through type. A total of 10 levels are set. The first level will show three apples, and three more apples will be added for each level in the future. In the new level, the length of the snake is restored to the default length, and the speed is the default speed.
9. Set the challenge limit function. Set the initial speed to 10 and the initial length to 10 for 100 apples.
