A 3D world without people is just a stunning scene; the true value of a virtual world lies in enabling people to meet and interact within it. The multi-player real-time interaction system of Chuangshi Virtual World CRM makes this possible. ## Technical Implementation The system adopts the WebSocket protocol to achieve real-time two-way communication between server and client. The positions, action states, and chat messages of all online players are synchronized with ultra-low latency. Built on Node.js, the server supports horizontal scaling, and the maximum number of concurrent users depends on server configuration. ## Core Interaction Features 1. Real-time Position Synchronization: Each player's movement is instantly displayed in other players' perspectives, creating a genuine sense of coexistence. 2. Mini-map Display: A real-time mini-map on the right side of the interface shows the positions of all online players, facilitating location and gathering. 3. Text Chat System: Supports global channels and private messages, with chat records displayed in the scene in real-time. 4. AI NPC Interaction: AI-driven NPC characters can be created, allowing regular users to converse with NPCs for guidance, question answering, or emotional communication. 5. Character Avatar System: Each player has an independent character avatar, supports custom appearance, and social identities are recognizable. ## Suitable Scenarios? - Virtual Communities: Membership-based social spaces where users can gather and communicate in the virtual world. - Online Exhibitions: Visitors can see other visitors in real-time, exhibitor representatives provide online reception, recreating the social atmosphere of offline exhibitions. - Remote Team Collaboration: Corporate virtual headquarters where team members check in daily in the virtual space, reducing the loneliness associated with remote work. - Teaching Interaction: Teachers and students share the same virtual classroom, with real-time 3D model demonstrations and interactive Q&A sessions. ## Deployment Recommendations A 2-core 4G server can smoothly support 20-30 concurrent online users. For larger-scale requirements, linear expansion can be achieved by upgrading server configuration without modifying any code.
