MPUZ: Dialog Commands
From Mario Fan Games Galaxy Wiki
Dialog files can make use of some commands that allow for different things to happen to the string. Commands are easy to recognize, as they are surrounded by '%' signs.
If, for some reason, a '%' is required within the text string of a command, you can escape it with \%; you can also escape those slashes with \\.
Commands
- %player%: Replaces itself with the save file's name.
- %wait X%: Pauses the addition of the following text for X amount of game loops (60 = 1 second).
