scrolling in sci0

[robingravel]

In king's quest 1 sci, I see a scrolling effect when Graham climbing up on the beanstalk. I wonder if I could add the scrolling effect in my game from left to right.

I think you could, after all, it's the same version of sci, isn't it?
By the Way, Naturette is great!

In short, no. But allow me to explain what's going on.
The scrolling that you see is a so-called "show style". There are
several others, like the "checkerboard effect", to name one.
You can use them by setting a value for the style property,
either in the properties section of your room object or in its
init method before calling the superclass. The available show styles
are listed in Brian's documentation for the DrawPic() kernel call, though
you do not need to use that kernel call explicitly to use show styles.
KQ1 is written in SCI01 which has a few extra show styles not found in SCI0.

A'right, lemme try.

What if, hypothetically, the Checkerboard thingy is code ... em... $05 and KQ1's scroller is code $20, k?
Now, the two engines are so gaddaym similar...

Just decompile the beanstalk script and find out the scroller's code (in this example $20). Then just copy KQ1's interpreter to your game (to enable the scroller) and use $20 instead of whatyamaycallitcheckerboardconstantthingy.

SCI Studio doesn't support SCI01. Though from the player's point of view they look identical, internally, they are not. SCI01 interpreters won't run SCI0 games. SCI01 interpreters are the beginning of Sierra's non-backwards compatibility and most SCI01 games won't run on other game's SCI01 interpreters.

So do I still able to make a scrolling game and will Sci Studio support sci01?

Brian: "MOST[/u] SCI01 games ..." ??  
I only know of 5:
1. QFG2
2. KQ1 SCI
3. Christmas Card 1990 - 16 Colors version
4. Mother Goose SCI - Amiga version
5. SQ3 - German (Multilingual).

Maybe someone knows of any other SCI01 games ?

[Brian Provinciano]

There's also Jones in the Fast Lane EGA, and probably more, I just can't think of on the top of my head. The thing is though, that most SCI01+ games won't run on other SCI01+ game's interpreters. That's why Sierra releases the new games in collection packs with the oldest interpreters.

[OmerMor]

Jones EGA - I guess you're right.
I once (million years ago) had an EGA version of KQ5. I guess it's also SCI01.
does any1 here have any of those versions BTW (Jones EGA, KQ5 EGA) ?

[Brian Provinciano]

I don't personally have KQ5 EGA, but I heard recently that it was a standard SCI1 VGA game with EGA drivers which dithered the colours. Only certain versions came with them though. I've got Freddy Pharkas, which is quite a bit newer, and it also has EGA drivers.

[Chris Cromer]

Yeah I have one of those SCI1 ega drivers as well, it came with Quest for Glory 1 remake. I beleive the EGA version of KQ5 was probably just a driver as well.

[OmerMor]

nope. i too have these drivers, but there was an EGA only version of kq5 which i once had before i got the VGA one. it was when it the game just went out.
this version was much smaller in size, which indicates that it didn't have VGA graphics.

[CapTAmerik@]

I remember something about KQ5 EGA. The game was released at the same time as the VGA-edition and came on less disks than the VGA-version.

KQ5 probably was Sierra's first try at VGA-graphics and way back then the standard was EGA. They wanted to make the game accessible to everybody and not lose a hundreds of adventurer fans to eg Lucasarts, simply by overdueing the system demands.... (a philosophy they soon threw overboard,  )....

It's good to see the my memory have not yet betrayed me  
Now time will tell if those EGA versions are lost forever or maybe someone might find a copy in his garage and upload it to the web, and there would be much rejoice..

I just picked up a boxed version of Leisure Suit Larry 5 on 5 1/4" floppies today (I only had the CD version before) from a software store down here in Vancouver, and it came with a form you could fill out to get a 16 colour version! I think it's safe to say pretty much every VGA SCI1/SCI11 game could be obtained in 16 colour form. Sierra probably just repackaged them with different drivers and sent them out. This seems odd, since the drivers are only a few KB and surely would fit on the disks. I wonder why they didn't include them along with the VGA ones.

I wonder what Sierra would do if I sent in the form, heh. With their current management, I doubt they'd do anything more than pocket the money enclosed. However, I actually read on MixnMojo that I guy found an old copy of Monkey Island with a similar form and recently sent it into Lucas Arts. Amazingly, they sent him the game! Unfortunately, they didn't send the floppy version he requested, but a brand new CD version!
