1. Choice of game engine and development environment
There are many mature game engines available in the market today, such as Unity, Unreal Engine, Cocos2d-x, etc. These engines provide a complete game development framework, which can save a lot of low-level development work and make game development more efficient. Choose a game engine that suits you according to your needs and experience.
In addition to the game engine, you also need to choose a development environment that suits you. If you use popular game engines such as Unity or Unreal Engine, they provide a powerful development environment by themselves and do not require other additional configurations. If you use a lighter game engine such as Cocos2d-x, you also need to install an IDE (Integrated Development Environment) such as Visual Studio, Xcode or Eclipse.
2. Game production process
The core of the parkour game is that the player keeps running in the game, avoiding obstacles, and getting as high a score as possible. Therefore, the key to game development is to design the game rules, level settings and operation methods.
Game development is generally divided into the following steps:
(1) Game Design
In the game design stage, it is necessary to determine the general content, gameplay and style of the game. Parkour games mainly test the player’s reaction speed and operating skills, so it is necessary to set different levels and increase the difficulty, so that players can experience challenges and a sense of accomplishment.
(2) Write code
Write game codes according to game rules and design schemes. Using C++ language to implement parkour games can provide higher performance and flexibility.
(3) Add game resources
Resources are an integral part of game production, including pictures, music, sound effects, etc. In a parkour game, you need to add running characters, obstacles, backgrounds, etc.
(4) Testing and improvement
After finishing the game, it needs to be tested and optimized. Testing includes game logic, level design, game performance, and more. According to the test results, adjust and improve the game.
3. Key technical points
(1) Game state machine
The state machine is a commonly used model in game programming, which can effectively separate the relationship between game logic and views. In a parkour game, the state of a character includes standing, running, jumping, sliding, etc., which need to be managed in the state machine.
(2) Collision detection
In the parkour game, the character needs to avoid obstacles, so the collision detection function needs to be implemented. When the character collides with an obstacle, the game should end or the life should be deducted.
(3) Animation effect
Animation effects are very important to improve the playability and experience of the game, allowing players to feel more realistic game scenes and operation methods. In parkour games, actions such as running, jumping, and sliding need to be realized through animation.
4. Summary
Parkour is a simple but challenging game type, suitable for beginners to practice. Using C++ language and a suitable game engine, you can quickly build a parkour game and lay the foundation for your own game development. Of course, it is necessary to pay attention to the game rules and design during the development process, so as to improve the playability and fun of the game as much as possible.

The following is a sample code for a simple C++ parkour game. Since the design and implementation of parkour games are relatively complicated, only the basic framework and the realization of key functions are given here.
