Okay, so as the title says, this is my Single Player Commands (or SPC to more experienced players) guide to noobs.
So lets start with the basics: /help>> Now this is a pretty simple yet helpful command that shows you all the commands, BUT, it does not however, tell you how to use them or what they do at times. So here is a LOONNGG List of SPC's and what they do:
/help: Displays the main commands
/me: Basically, its just a differet type of chat that lets you talk in third person (ex: /me
/weather: this allows you to change the weather for a set amount of time, but to a max of 10,000 seconds.
/toggledownfall: this is basically the same as ^this^ but, it only stops/starts the rain
