"Is-A" refers to the "one" of one class and belongs to another class, while "Has-A" is different, which indicates that a certain role has a certain responsibility. A common reason for the wrong use of inheritance instead of aggregation is to mistakenly treat "Has-A" as "Is-A". For example:

State machines also have a wide range of uses in game development, especially the logic writing of game AI. The main characters in the game have various states such as walking, attacking, defending, falling and jumping. These states are both interrelated and constrained. For example, if attacked during walking, it will switch from walking state to falling state. In the state of falling, it can neither attack nor defend. Similarly, you cannot switch to the defensive state during the jump, but you can attack. This kind of scenario is very suitable to be described by state machine. The code is as follows:

D) Practicality and skepticism. When looking at shallow reference books or looking up materials on the Internet, you should type (copy or copy) the code and run it yourself. You should modify other people's source code more and put forward your own opinions: why is the book not designed like this and why is it designed like that? What if you add some methods, method parameters, or member variables? You must do it yourself, at least run it. In addition, we should dare to ask questions and make bricks to bloggers. You can even question the commentary and intention of some chapters of GoF, not to mention some bloggers.
