Create: WarHorn
by tek_sama
Create: WarHorn is a NeoForge add-on that turns rotational power into a directional acoustic horn, so a player can send a sound alarm across long distances.
What it does
The horn takes rotational power from a shaft on its rear and stores it as internal pressure in a tank. A higher rotation speed fills the tank faster. Once charged, a redstone pulse releases a single directional blast with high-pressure air particles, and the deep sound it produces can be heard hundreds of blocks away. The block works as a standard stationary block and can also be placed on simulated airship bodies, moving contraptions and trains.
The mod depends on Create and is published for NeoForge 1.21.1 only. The server and every player need the mod installed. The mod is not open source; it is released under All rights reserved, and the author is tek_sama. Crafting components are viewable in JEI, and charge level can be read with Engineer's Goggles.
Key features
Rotational charging
The horn is powered by a rotating shaft and builds pressure over time, with higher speeds shortening the charge time.
Redstone release
A redstone pulse fires the charged horn, sending one directional sound blast in the direction it faces.
Long-range sound
The blast produces a low sound wave that carries across hundreds of blocks, which suits base alarms.
Pressure readout
Engineer's Goggles display the current internal pressure and rotation speed in real time.

Use cases
Base alarms
A horn placed at the edge of a base can signal players across a large area when a redstone circuit triggers it.
Moving contraptions
The horn can be mounted on airships, trains and other moving Create contraptions as well as fixed structures.
Who it’s for: Create players who build alarm systems or want a long-range sound signal on Create machinery, and server owners who run Create builds that need one.
