1:55:56longboolean Q: Now that we are using this method to assign tags, does this change how you plan to organize lots of little items on a sheet that may have differing, non sheet-wide tags, and in cases where using significance of positioning in the sprite sheet is too limiting? For example, maybe a collection of different fauna, each plant may have different tags for attributes, but can not be easily put into categories

2:01:59ivereadthesequel Q: I wasn't here for all of today's stream, but is RequireToken() what you'd use for lookahead (or a peektoken), ensuring you have an upcoming series of tokens to be of a specific form before you process those tokens?
