BuilderHelper

World-editing toolkit for Hytale — swap materials & generate shapes.

Description

BlockMorph is a server-side Hytale plugin that gives builders two powerful tools in one UI:

Material Swap — Select a group of blocks (via Selection Tool or manual coordinates) and instantly convert their material while preserving block shape (stairs, slabs, walls, fences, roofs, doors, etc.). Pick from an auto-generated list of compatible material variants.

Shape Generator — Hold any block and generate geometric shapes: Cube, Sphere, Cylinder, Pyramid, Cone, and Torus. Adjust radius, height, size, hollow mode, and preview the result in real-time before committing. Fly around the preview freely to inspect it from every angle.

Both tools share a full undo history (up to 5 operations).

How to Start

Place Builder Helper.jar into the server's mods/ folder
Start the server — assets deploy automatically
In-game, run:

Command	Description
`/vui`	Open the main UI (both panels)
`/vpos1` / `/vpos2`	Set selection corners manually
`/vconvert <material>`	Convert selection via chat
`/vblocks <query>`	Search available block IDs
`/vundo`	Undo last operation

Workflow

Swapping materials (right panel):

Select blocks with the Selection Tool or /vpos1 + /vpos2
/vui — pick a target material from the list
Click Convert — done, rotation and shape preserved

Generating shapes (left panel):

Hold the desired block in hand
/vui — choose shape, adjust parameters
Click Preview: ON — shape appears in front of you, UI closes, fly mode activates
Fly around to inspect; run /vui again to tweak parameters or click Move to reposition
Click Generate to place permanently, or Clear to discard
