Creative Block Replacer

Creative Block Replacer is a minimalistic mod which allows easy switching in between placing and replacing blocks in creative mode, speeding up the creative process.

Block replacing mode is toggled with the press of a button. By default it's I, but this can be changed in Options -> Controls. When enabled, right-clicking a block replaces it with the block in your hand. The new block keeps the rotation of the old one, so stairs replaced by other stairs keep facing the same way.

The keybind requires the mod on both the server and the client. Players without the mod on their client can toggle it by sneaking three times while standing still, or via the /cbr command. Sneaking can be enabled for players with the mod as well in the config.

All available config options:

tripleSneakWithoutClientMod default true
Whether players without the mod on their client can toggle block replacing mode by sneaking three times while standing still.

tripleSneakWithClientMod default false
Whether players with the mod on their client can toggle block replacing mode by sneaking three times, next to the keybind.

Either /creativeblockreplacer or /cbr can be used.
/cbr toggle - Turns block replacing mode on or off.
/cbr enable - Turns block replacing mode on.
/cbr disable - Turns block replacing mode off.
/cbr usage - Shows the list of commands.

To toggle in between block replacing mode:
Press I, or use /cbr toggle

Without the mod on the client, sneak three times while remaining in the same position:

When replacing block mode is enabled, right-clicking a block will result in the target block being replaced with the item in hand:

You may freely use this mod in any modpack, as long as the download remains hosted within the CurseForge or Modrinth ecosystem.
