Missing Mods Checker (1.21.1, 1.20.1) – Prompts Players to

Missing Mods Checker helps modpack makers make sure players have all the right files before the game starts. This mod looks at your game folder during the loading screen to see if any important parts are gone. If something is missing, a popup window appears on the screen. It tells you exactly what you need to get before you can play. You can easily click a button to grab the missing files and restart your game safely.

Features:

• Startup Check: Scans for missing files before the game fully loads up.
• Stops players from accidentally or purposely deleting important files.
• Locks specific file versions so players do not break the pack with the wrong updates.
• Tells players to get files that are only hosted on other websites.
• Lets players choose to add optional extra files the first time they open the game.
• Shows a simple popup window with a list of everything that is missing.
• Download Button: Opens your web browser directly to the right link to get what you need.
• Folder Button: Opens your game folder right from the popup menu to make adding files easier.

Configuration:

• Edit the missing_mods_checker.json file inside your config folder to set up your lists.
• Use exact file names or special text rules to match the exact versions you want players to use.
