Project Scaffold

Project Scaffold is a small quality-of-life Fabric mod for Minecraft 1.21.1 that lets you replace scaffolding blocks in one quick action.

Normally, if you build with scaffolding and later want to replace it with a real block, you have to break the scaffolding first, wait for the space to clear, and then place the new block. Project Scaffold makes that workflow faster: right-click scaffolding with a placeable block in your hand, and the mod will break the scaffolding and place your selected block in its position.

Features

• Replace scaffolding by right-clicking it with a placeable block.
• Works with blocks held in either the main hand or offhand.
• Keeps normal Minecraft placement rules.
• Falls back to vanilla behavior when the held block cannot be placed there.
• Excludes scaffolding itself from replacement behavior.
• Works in singleplayer worlds.
• Includes a client-only fallback for servers without the mod installed.

Behavior

When the mod is installed in singleplayer or on both client and server, scaffolding is handled cleanly by the server-side logic. The scaffolding block is broken without dropping normally, then it is returned to the player’s inventory if possible. If the inventory has no room, the scaffolding drops at the replaced position.

When used client-only on a server without Project Scaffold installed, the mod attempts to perform the same action using normal client interactions: break the scaffolding first, then place the held block. In this mode, the server still controls the final result, so behavior may depend on latency, permissions, server rules, and other mods.
