Questions on how to preface my game.

I want to write a preface to my game that allows the player to peruse various materials(credits, author comments, possible hint files, etc) prior to beginning the game. I have a good idea of the format of what I want(possibly a dream sequence in a library). I want to be able to put the player in that sequence, and when s/he is done, s/he can proceed to the beginning of the game(by entering a one-way exit from the room and on to the beginning)–all before the banner is presented. I want the screen to clear, and then the banner appears, and play begins in earnest. Can I do this as a part of the ‘When play begins’ rule? Or do I simply change the rule for printing the banner, and use a ‘Before’ rule to write the initial text about the player waking up at the beginning of the game(followed by the description of his room)?
Thanks

Here is an example game which gives the desired effect:

[rant=Code]Include Basic Screen Effects by Emily Short.

The Library is a room. “You can go outside, when you’re ready.’”.The Forest of Doom is a room.

The Forest of Doom is outside from the Library.

Before going outside from the Library:
say “You step out into the unknown…”;
clear the screen;

After going outside from the Library:
say “[banner text]”;

Rule for printing the banner text when the player is in Library: do nothing.[/rant]

Thanks Peregrine–
Will this extension work with a Glulx format?

Okay, I read about that extension, and it does work with Glulx(except for the screen color aspects). Now my question is, how do I find out if it interferes with my source code(I have essentially ‘finished’ the game and am adding features)? What if clearing the screen is all I really want from it? Thanks

I think that blocking the banner with the condition that the player is in the library is too restrictive: if the player types VERSION or TRANSCRIPT while in the library, the banner should still appear in my opinion.

I would do it like that:

[code]Include Basic Screen Effects by Emily Short.

The Library is a room. “You can go outside, when you’re ready.’”.
The Forest of Doom is outside from the Library.

Before going outside from the Library:
say “You step out into the unknown…”;
clear the screen;

After going outside from the Library:
say “[banner text]”;

The display banner rule is not listed in the startup rulebook.[/code]
In fact, I think the example “Bikini Atoll” should do the same thing.

As for Basic Screen Effects, I don’t think it can interfere with something.

Thanks–I may use that extension in a future game.
