Grenadier

Players throw five kinds of grenade: smoke, incendiary, fragmentation and impact, plus three deployable mines: anti-personnel, directional fragmentation and thermite. Mines are placed as entities rather than grid-locked blocks, so they can sit on any suitable surface. Every device carries a distinct gameplay role, model, texture, deployment behaviour and set of parameters that the server can adjust. Armed mines detonate when vanilla arrows and other compatible weapon projectiles strike them.

Smoke is drawn with Veil's volumetric rendering instead of ordinary smoke particles. A reusable signal beacon releases colored smoke with a centered vertical beam, and its color changes with Minecraft dyes. The server settings decide how long an activation lasts and how long the cooldown runs. Grenadier requires Sable and Veil. Veil is needed only for client rendering, and another compatible mod that already supplies Veil makes a duplicate copy unnecessary.

Both the server and every player's client need Grenadier installed for it to work. On first world opening it generates a server configuration, which modpack authors can copy into newly created worlds. The mod is published for NeoForge only, for 1.21.1, under All rights reserved, and it is not open source.
