Is there a manual somewhere for Glulx? I’d like to use timers, but can’t find documentation about them in the Inform7 manuals. The Glulx Entry Points says that it allows the author to set responses to Timer events, but doesn’t give syntax or examples for doing so.
(I tried using Basic Real Time by Sarah Morayati, but her example code isn’t compiling).
Timers aren’t handled by the Glulx VM but by the Glk library. You will want the Glk specification if you are going to do any Glk hacking. But like you say, there are already extensions for this kind of thing. If you tell us which version of Sarah’s extension you’re using, post your source, and mention the problem messages, the folks here can probably tell you how to get things working.
