Happy Ghast Scaffolding

Once a player right-clicks empty space, the happy ghast the player rides places a block from the mainhand or offhand at that spot. Because a happy ghast spans exactly four blocks across, the area it covers holds a grid of 16 positions, and the player moves to line up with that grid before placing. In survival and adventure modes, placed blocks are taken from the inventory; in creative mode the inventory is left unchanged.

The datapack matches items to blocks by ID, so it works with both vanilla and modded blocks as long as the item ID and block ID are the same. Items whose ID differs from the block they produce do not place that block; a water bucket, for example, does not place water because its item ID is minecraft:water_bucket rather than minecraft:water. Placing sounds do not match the block type. The author recommends using the hgs:toggle function to disable the scaffolding sounds.

The mod is distributed as a datapack for worlds, so it needs no mod loader to run. It can be added to a pre-existing world or a new world, and it is removed by uninstalling the mod or datapack. The mod is released under the Apache License 2.0 and is not open source. Files exist for 1.21.6, 1.21.7 and 1.21.8 across Fabric, Forge, NeoForge and Quilt.
