Create: Shield

Create: Shield is a Minecraft NeoForge 1.21.1 mod that adds two powered blocks to Create and optionally Sable: the Clockwork Block (power battery) and the Shield Block (cone-shaped entity pusher).

Dependencies

1. Clockwork Block — Power Battery

The Clockwork Block is a mechanical device that can store and release rotational kinetic energy, essentially a giant "rechargeable battery."

1.1 Block Structure

1.2 Operation Modes

Charging Mode (no redstone signal)

• Receives rotational power from the back, converting kinetic energy into internal stored energy.
• Stress consumption = RPM × 256 (SU)
• Maximum energy storage: approximately 2 billion SU·tick
• Requires sufficient stress capacity from the external network while charging.

Discharging Mode (redstone signal applied)

• Releases stored energy and outputs rotational power from the front.
• Provides unlimited stress capacity (backed by stored energy).
• Discharge consumption = ceil(stress demand) SU·tick, deducted from stored energy.
• Automatically stops output when stored energy is depleted.

2. Shield Block — Cone‑Shaped Entity Pusher

The Shield Block is a cone‑area entity pushing device that uses rotational power to generate a repulsion field in front, pushing entities away.

2.1 Block Structure

2.3 Cone Scanning Mechanism

When supplied with sufficient stress, the Shield Block creates a cone‑shaped scanning area in front:

• Repulsion angle φ = 45° – 270° (opening angle of the cone). Adjustable only if a Nozzle is installed; fixed at 45° without a nozzle.
• Repulsion range r = RPM / 8 (radius of the cone area)
• Repulsion strength flow = redstone signal strength
• An entity / physical structure (from Sable) is pushed only if it lies within the cone angle and is not blocked by line‑of‑sight.
• When a nozzle pushes a physical structure (Sable) from a subspace into the overworld, the Shield Block itself is pushed back.

2.4 Frequency Linking System

The Shield Block supports wireless frequency linking, enabling multiple blocks to work together:

1. Place items in the two frequency slots to set the frequency.
2. Supports Create’s wireless redstone adjustment.
3. Physical structures belonging to Shield Blocks that share the same frequency pair are "allies" — they will not push each other within the same subspace, preventing same‑frequency structures from being blown away.
