Debugging Server Menus with Packet Control

Testing Menu Behavior

UI-Utils Advanced Mod lets you inspect how menus communicate with servers. When you open a chest or inventory, a control panel appears on the left side showing the menu's sync ID and revision numbers—hidden details normally invisible to players.

You can delay or stop click packets from reaching the server, letting you see what happens when actions don't send immediately. Close a menu on your screen while the server still thinks it's open, or use the built-in chat box to run commands without closing the menu.

Use ,plugins to scan for server anti-cheats, ,vclip and ,hclip to test position changes, or ,math to calculate expressions. Press V to reload saved menu screenshots. This tool is essential for finding bugs and understanding server-side menu logic.
