Walkable iso plaza with three synthetic peers wandering randomly. The local player (blue) walks via WASD or arrow keys. Three other peers (Alice/Bob/Carol, red/green/yellow) are driven by a MockMultiplayerBridge that pushes presence.update messages every 100 ms, exactly mirroring the wire protocol an SSE-backed server would emit. Swap MockMultiplayerBridge for SSEMultiplayerBridge and the same engine code drives a real backend. back to gallery · view source
