mutual synchronization. It is a well-predicted solution for the future of the network. The reason for this solution is not to say that we have fully implemented this solution, but to apply some ideas of this solution to some aspects of the online game field. I named this solution semi-server synchronization. The general design concept is as follows:
First, the client needs to create many broadcast lists wh
Before talking about this topic, let everyone know what a server is. In online games, servers play the role of synchronization, broadcast and server-initiated behaviors, such as weather, npc ai, etc, the reason why many online game servers need to carry some game logic operations is to prevent client cheating. With thi
restored.2. Common OnLine processes
The INFORMIX-OnLine dynamic server uses several oninit processes to perform its own operations. Generally, several oninit processes exist in the system. Each process is called a virtual processor of the OnLine system.
The oninit process is run as root. This is the user permission re
solution, known internationally as mutual synchronization, as a well-predicted solution to future network prospects. The reason for this proposal is not that we have fully implemented this approach, but that some of the ideas in this scenario are applied to certain aspects of the online game domain. I named this scenario: half-server synchronization. The general design ideas are as follows:First, the clien

Presence processing is the core of IM server and the most complex part of IM server. A user's status changes and needs to be automatically delivered to all his online friends through the server. Therefore, the presence module actually waits for the same message processing server
In this section, I want to talk about the design of scripts on the server. In the previous chapter, some script-related things have been introduced when talking about NPC intelligence. Let's talk about the role of the script first.
In a compiled server-side program, you cannot build something during the program running process. Therefore, you need the support of the script language. Because the script langu
Next, I want to talk about the NPC design and NPC intelligence on the server. First, we need to know what the NPC is and what the NPC needs to do. The full name of NPC is (non-player character). Obviously, it is a character but not a player. From this point, we can know that some NPC behaviors are similar to those of players, he can walk, fight, and breathe (This point is mentioned in the later NPC intelligence). What's different from the player's obj
