In Yarn Spinner, you can send instructions to your game through commands. Commands look like this:
Commands are sent to your game's Dialogue Runner, just like lines and options are. Commands are not shown to the player directly; instead, they're used for things like stage directions.
Yarn Spinner comes with some built-in commands; however, to get the most usefulness out of them, you'll want to define your own custom commands that make your game do what you need to.
There are two built-in commands in Yarn Spinner: wait, and stop.
waitThe wait command pauses the dialogue for a specified number of seconds, and then resumes. You can use integers (whole numbers), or decimals.
stopThe stop command immediately ends the dialogue, as though the game had reached the end of a node. Use this if you need to leave a conversation in the middle of an if statement, or a shortcut option.
You can create your own commands, so that your scripts can send directions to your game. For more information on how to create them in Unity games, see Creating Commands and Functions.
