Widgets are the best entry point for game modding in BAR. Start by reading existing examples and testing incrementally.

Widgets run client-side and do not affect game sync, making them the safest place to experiment. Prototype and test without risk of desyncing other players. The BAR repo contains dozens of working widget examples that cover most common use cases. Read those examples first, then write your own starting from a similar template.
The most effective way to learn BAR Lua is reading widgets that already solve the problem you are targeting. The engine API documentation exists but varies in usefulness. Checking how other widgets call the same API functions is often faster than searching through sparse documentation. The BAR modding channels pin useful resources for newcomers.
If a mod produces invalid command errors when you try its Base64 tweak input, the mod is likely outdated or abandoned. Check the infolog file for nil errors in that case. Search for "error" using CTRL+F and look specifically for nil references, which indicate the mod is trying to access missing definitions.
Tweakdefs and tweakunits load in numbered order from 1 through 9. The final assignment of game values follows the reverse order of tweak execution, meaning later tweaks override earlier ones. Plan your tweak chain carefully when using multiple entries to ensure the desired final values appear.
Newcomers who ask clear questions and share their learning path help everyone who follows them. Creed of Champions builds on that cycle by welcoming new players with patience and structured guidance. No one gets mocked for starting at zero.
One of the few places where you can coordinate with people in matches with a good supportive attitude. Everybody tends to be understanding and constructive.
