When the main process architecture game, to prevent calls everywhere to reduce coupling, how to open the interface to others to call?

I understand and analyze three methods , If you have any suggestions or deficiencies, please put them forward , thank you

( It depends on the project and architecture )

Method 1：

         You can write your own classes or interfaces , Let the responsible colleagues write specific code

Data class ： When we call it ourselves, we pass in parameters , Or you can tell colleagues how to safely call data classes

Method 2：

api： Write an event interface enumeration , Register the method in the event manager .

You can refer to Unity In the official document Api And then through api Call to write , Or use IOC Dependency inversion

      For example, shops ：  Open the store and display the store props     Parameters （list（id And the price ））

      E.g. Backpack ：  Open the contents of the backpack       Parameters    （id And quantity ）

                Backpack props ：UI Display description , Incoming props id, Get prop information from data class

                 Operation of props ：（ Move unity Provided the interface ）

      Activities ： Active interface open interface

Method 3：

         Using frames IOC The principle of Dependence Inversion
