The hero of World War II is a game I like very much. Although it was a bit old in years, I always took it out for a long time. There is no repair box in the reward task "tank attack". It is a pity to watch the damaged tanks. some people say that they want to use mod, but they haven't found the legendary tank repair mod for a long time and finally found a method to modify the archive. share it! Although prog

Document directory Gof Definition Motivation Key points of the decorator Mode Gof Definition Dynamically add some additional responsibilities to an object. The decorator mode is more flexible than the subclass generation function. Let's take a look at a small example. If we need to develop a tank for the game, apart from the tanks of different models, we also hope to add one or more of the following features to tanks in different scenarios: infra

For example, after mysql is installed and configured, there is a built-in mysql database with a user table to store users and user permissions. mongodb is the most relational database, is there a table like this.1. Master the permissions and understand the following four items.1. mongodb does not have a default administrator account. Therefore, you must first add an administrator account and enable permission authentication.2. Switch to the admin Database. The added account is the administrator

Bridge Bridging Mode (structural mode)Abstraction and implementationAbstractions should not be dependent on implementation details, and implementation details should be dependent on abstraction.Abstract b stability, implementation details B changeThe problem is that if abstract B is inherently unstable and likely to change because of its inherent causes, what happens?For exampleIf we need to develop a tank game that supports both PC and mobile, the ga
