Create Copycats Roller

Create Mechanical Rollers, now with Copycats+ layers.

Build smooth railway foundations along straight, diagonal, and curved tracks
in 1/8-block steps.

Features

• Precise Copycat paving along railway tracks
• Layer, Half Layer, and Slope Layer support
• Automatic Layer/Half Layer selection with a Zinc Ingot
• Blocks selected by Create or compatible Roller-filter mods fill Copycats
• The same blocks continue normal Create paving in empty spaces
• Safe item use with no hidden material balance

Filters

Put one of these items in a Mechanical Roller’s filter:

• Copycat Layer
• An adjustable surface in 1/8-block steps
• Copycat Half Layer
• Independent height on both sides
• Copycat Slope Layer
• A smooth slope where a suitable state exists
• Zinc Ingot
• Automatically chooses Layer or Half Layer
• Any supported block or compatible modded filter
• Applies the block actually selected for each position to Copycats and continues normal Create paving

Addon features are active in Fill (STRAIGHT_FILL) mode. Tunnel and Wide
Fill keep their normal Create behavior.

Compatible filters need no dedicated integration: Copycat Roller follows the
block selected by the normal Roller placement transaction.

Item Use

• layers=N costs N Layer or Slope Layer items.
• A Half Layer costs the sum of its two sides.
• One Zinc Ingot makes up to 8 Layers or 16 Half Layers. Change is kept as real Half Layer items.
• Filling a Copycat costs one material block per empty part. Normal paving consumes its usual additional blocks.

Existing player-assigned materials are never overwritten. If the complete
cost is unavailable, the operation is cancelled safely.

Requirements

• Minecraft 1.21.1
• NeoForge 21.1.x
• Create 6
• Copycats+ 3.0.4
• Java 21

Install the requirements and place Copycat Roller in the mods folder on both
client and server.

Configuration

The config can change height rounding, surface-only paving, Copycat fill
depth, and Slope Layer accuracy. By default, the Roller rounds down and places
only the nearest upper Copycat surface.
