I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

B's KnockOnDoor

B's KnockOnDoor is a simple roleplay plugin that enables you to left-click any door to knock on it. Each door has a slightly different tone, making them distinguishable. Newest version allows for windows to be knocked on. You can also knock on trapdoors. To hear all the tones and see how it works, check out the video below.

Customization options are available in the \plugins\B_s_KnockOnDoor.yml file, where you can adjust settings to fit your needs. These settings allow you to control whether players can knock on trapdoors and whether they can knock with tools or only with empty hands etc.
