Hazard Diamond
by spadeteam
Hazard Diamond is a library mod that lets players create and display NFPA 704 hazard diamonds in the world without writing any code.
What it does
Hazard Diamond implements the NFPA 704 hazard identification standard, the placard widely called the fire diamond. Players craft a Hazard Diamond item by placing dye of the matching quadrant color around a diamond iron ingot in the center, then place it in the world like a normal block. The placed diamond stays editable: a player approaches it and interacts to open an edit screen, and sneak-interacting with a honeycomb in hand waxes it into an immutable state.
The mod is primarily a library. Via its API, a mod can open an editable screen on the client, similar to a placeable entity, and receive the changes players submit. Installation requires Fabric API. Hazard Diamond runs on client and server, so the server and every player need it. Files are published for Fabric and Quilt for 1.20.4, and the code is under the MIT License, so the mod is open source. Optional support includes Mod Menu, WTHIT and YetAnotherConfigLib (YACL).
Key features
NFPA 704 placards
Diamonds follow the NFPA 704 standard, with health, flammability, instability and special hazard quadrants set by the player.
Craftable diamond item
The item is crafted from dye, a diamond and an iron ingot, so each quadrant color can be chosen at the crafting stage.
Editable and waxable placards
A placed diamond opens an edit screen on interaction, and a honeycomb locks it so the entity shows an immutable state.
WTHIT tooltip
With WTHIT installed, the hazard data of a placed diamond appears in a tooltip.
