Learning Minecraft Command Block Programming, Part 9 - JSON, tellraw, and clickable signs

I'll teach you Minecraft command block programming! This series will help you learn step-by-step using the 1.9 snapshots of Minecraft for PC. Today we'll learn how to make fancy text and have players activate commands by clicking signs or chat. This episode covers - the /tellraw command - basic JSON (JavaScript Object Notation) syntax: strings, arrays, and compound objects - using JSON with /tellraw to make text bold or colored - using JSON with /tellraw to print scores, or print player names via selectors - using JSON with /tellraw to print clickable text in the chat, that runs a command when clicked - creating signs with arbitrary sign text using commands - using JSON on signs to do all the same things as tellraw (but with escaped quotation marks - backslashes in front of quotes) - the advantages of clickable signs versus buttons or other redstone mechanisms (identifying the activating player) More on JSON: http://www.json.org/ More on JSON in Minecraft commands: http://minecraft.gamepedia.com/Commands#Raw_JSON_text Teaching programming to a wide audience is a challenge. I'll try to go at a slow, detailed pace that most viewers can follow. If you know a topic well, you might want to watch at 1.5x or 2x speed to skim. Teaching complicated subject matter is a challenge. During an episode, I sometimes do 'handwaving', or tell white lies or lies of omission, for simplicity to teach beginners. At the end of each epsiode, I'll have a segment where I try to clear up the lies I know I told, going into more gory detail.
