Laser Utils
Laser Utils is a Forge library for Minecraft 1.21.1 that makes it easier to add laser beams and ray casts to a mod.
What it does
Developers use the library to build laser weapons such as a laser rifle, and to work with ray casts more directly than the base game allows. Modders can register objects such as armor materials and entity types through one set of helpers, and attach translations, tag keys and models to what they register.
Networking is covered as well, with support for creating new packets, plus registration of layers for skull blocks and extra attributes for items. Forge is the only loader supported, and the 1.20.1 and 1.21.1 builds are published under the GNU General Public License v3.0 only, so the code is open source. Client and server both need the library, since it sends its own packets between the two sides.
Key features
Laser and ray cast tools
Helpers for laser beams and ray casts, so a laser rifle or similar weapon can be built without writing the trace logic from scratch.
Registration helpers
Items, blocks, attributes, entity types, enchantments and armor materials can be registered through the library's utilities.
Models and translations
Item and block models, language translations and tag keys can be applied to the objects a mod registers.
Custom packets
New networking packets can be created for communication between the client and the server, and entities can be defined with their own models.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Laser weapon mods
A modder who wants a laser rifle or beam-based gun can use the ray cast support instead of building the tracing code by hand.
