Fluid Shell Extensions
by xiao-ou6630
Fluid Shell Extensions is a Forge addon for Create Big Cannons that lets fluid shells trigger custom effects defined in JSON files.
What it does
Fluid shells fired from Create Big Cannons can carry effects defined by the author. Each effect is written as a JSON file, so adding one needs no Java code. When a shell lands, a fluid may leave source blocks behind, drop items, apply potion effects, cause explosions or emit particles.
Effects can be staged so that different results follow from how much fluid the shell holds. Conditions can also check whether another mod is loaded, which supports cross-mod integration without a hard link. Each fluid takes its own JSON file, and naming it after the fluid's registry name, such as create chocolate.json, is recommended. Create Big Cannons is required, and the environment is client and server, so the server and every player need the same configs.
Files are published for Forge on 1.20.1, and the code is open source under the MIT License. A detailed logging option traces which effects run, which helps when a configuration does not behave as expected.
