What are the methods of inter-process communication in Unity?

There are several methods for inter-process communication in Unity.

1. Communication over the network can be achieved by using the TCP/IP or UDP protocols, with data transfer between processes facilitated by sockets.
2. Using shared memory: data can be stored in a shared memory area, allowing different processes to communicate by reading and writing to the shared memory.
3. Using a message queue: You can utilize the system’s message queue to achieve asynchronous communication between processes. One process can send a message to the message queue, while another process can receive the message from the queue.
4. Pipes can be used for inter-process communication, either through named pipes provided by the system or anonymous pipes. Pipes allow for communication in one direction or both directions.
5. By using semaphores and mutex locks, it is possible to control access between processes, as well as achieve synchronization and mutual exclusion between processes.
6. Using shared files: Data can be saved to a shared file, and different processes can communicate by reading and writing to the file.

It is necessary to choose the appropriate inter-process communication method according to specific needs and scenarios.
