I want to see more events made and I think helping proliferate the tools to make good and engaging games would help! This post will talk about the tools used to do that. Building the Map Having a well built map is as important as the inner workings. CW has WorldEdit enabled in NH. WorldEdit, WE, can help build large structures quickly. WE can do a lot of really cool stuff, as documented here. WE has a mod that allows you to see the boundaries of your selection, called the WE CUI. It does become problematic when you want to build really, really, big things. I recommend having WE installed in a SP profile. This can be pretty hard but, there is a tutorial. After installation, you can build things that would otherwise be difficult to build on CW. Internals Something I do, is to test commands in SP. Because the server is public, it makes sense to prevent everyone from getting to command blocks. This can however make it hard to get a nice and complicated event. The Minecraft Wiki documents the commands very well. There are also tools for building custom commands: CommandCreator - to make event commands. Give Generator - to make custom books and things, not the best. Tools for Minecraft - generally helpful.
