Hi guys, I just noticed that when I type "." nothing happens. Can I use it as a command for something? How? Thanks

A period is a separator between commands. So if you do "n. s", then it will go first north and then south. You can't do much else with it.

It has drawbacks. For example, I had a character named "Mr. Garlan" once. When I typed "x mr. garlan", it turned it into two commands ("x mr" and "garlan"). It took me a while to figure out why it actually did the look but then gave an error.

I see, isn't it better to do that with a "," or an "and" and let free the "."?

I believe a period was the historical Infocom multi-command separator (where "and" was used more for joining multiple objects - like "drop apple and banana"). So there is some precedent.

But feel free to customize it however you like...

I don't remember that, I though it was a "," but anyway, how can I customize that?

Keep in mind that I'm looking at the 5.5 source...

In HandleCommand, there is this line:

commands = Split(command, ".")

You could either change the "." to be "," (if that's what you want), or you could just generate an empty list and add the single command:

commands = NewStringList()
list add(commands, command)

In theory (in other words, as far as I suspect without having tested it), you'd get the "." through, and you could match on it. I know you can use odd punctuation in your commands - I experimented for a while with having a command like this:

"some dialogue text

where the command was the quote, and the rest would be input dialogue from the player. Of course, I had no idea what to do with the text once it was input, but I did work out that you could have odd commands like that.
