Besides SRB2's wiki and its source code on github, I've been using other mods to help learn how Lua works and have applied that learning to my own code. But if for example a mod does something I wanted to do but didn't know how to code (breaking FoFs, breaking spikes, wall angle detection, or a randomized sound list), and the mod is not marked [Reusable], how do I avoid plagiarism when it's where I learned how to do the code from?
