Silver consignment:
Define a global manager on the mailserver to manage the consignment of all players' silver. After the mailserver receives the message of consignment/purchase of silver, it will transfer it to the sceneserver for corresponding
processing. After the processing is successful, it will return to the mailserver for processing.
Prop auction system: The
processing process is basically the same as that of silver consignment. Both define a global manager on the mailserver for management, and then communicate with the sceneserver to complete the requirements.
The prop auction system is more complicated and has more data. You can use struct pointers to manage the data, but you need to pay attention to memory leaks.
