-
-
- Requirements:
- =============
-
- Supercoast requires at least a 286 computer running Microsoft
- Windows (TM) version 3.1. It will not run very well on a 286 or
- slow 386, however. Supercoast achieves it's best performance when
- a numeric processor is present. (486's all have built in numeric
- processors except the SX models, and 387's installed with 386's are
- numeric processors).
-
-
-
- Installation:
- =============
-
- If you have a numeric processor (a 287, 387, or 486 non-sx),
- copy the included file "scoast87.scr" to the windows directory
- (usually c:\windows). If you do NOT have a numeric processor, copy
- the file "scoast.scr" to the windows directory. Once you have
- copied the proper file, load the control panel in windows (usually
- located in the Main group). Double-click the desktop icon and
- choose "Roller Coaster" from the screen saver choices.
-
-
-
- About the Program:
- ==================
-
- Supercoast is a screen saver for Microsoft Windows (TM) version
- 3.1. Screen savers are designed to protect your computer monitor
- from burn in by not allowing a constant pattern to remain on the
- screen. Supercoast accomplishes this by displaying different line
- drawings quickly as the roller coaster moves around the track. The
- result is a three dimensional eye-view as if your were riding a
- roller coaster. Additionally, Supercoast moves the flat image
- slowly back and forth over a distance of 60 pixels to prevent
- constant vertical lines from existing. For maximal screen-saving
- properties, set the track thickness to 0 (see below).
-
-
-
- Setup Option:
- =============
-
- Supercoast has many options that can be set by using the setup
- dialog. To do this, select desktop from the windows control panel,
- and select the Roller Coaster screen saver. Then click on the
- 'setup' pushbutton. The setup dialog will now appear and options
- can be set. Explanations of these options follow:
-
-
-
-
- A. Time Interval:
- ------------------
-
- The time interval is an integer number that can be specified by
- the user. This value is the number of milliseconds to display a
- frame of the motion until a new frame is redrawn. The higher the
- number is, the slower the roller coaster will go. This can be
- useful to even out the performance of the coaster on a slower
- machine, or to slow down the amount of cpu time that the coaster
- takes up (to improve performance of other programs running in the
- background)
-
- B. Use Intermediate Bitmap:
- ----------------------------
-
- As a default, this is not selected. Normally, all of the
- 'drawing' of the roller coaster is done as you watch. If you have
- the track thickness set high, and/or other options, this may create
- an annoying flicker on the screen. With the intermediate bitmap
- option set, all drawing is done in memory, and then the final image
- is sent to the graphics hardware. This eliminates much of the
- flicker, but will probably slow down the motion of the roller
- coaster, especially if a high-color graphics mode is used. Whether
- or not this is a good option for you to set depends on what kind of
- graphics hardware you have, which graphics mode you use, and what
- other options you use. Try both ways and pick the one that works
- best.
-
- C. Track Thickness:
- --------------------
-
- The track thickness option allows you to select the diameter of
- the track pipes. Generally, As the thickness of the pipes
- increases, the performance of the roller coaster slows. A value
- of 0 creates only line drawings and eliminates all computation of
- thickness, and is therefore the fastest option.
-
- D. Track Color:
- ----------------
-
- The track color options allow the user to combine values of
- red, green, and blue to arrive at the desired color. Values should
- be in the range of 0-255. If you are not in a full color graphics
- mode, Windows will choose an available color which most closely
- represents the values you have chosen.
-
-
- E. Initial Velocity:
- ----------------------
-
- This specifies the velocity of the roller coaster at the
- beginning (top) of the track. The greater this number, the faster
- the roller coaster will go.
-
- F. Gravity:
- -------------
-
- This value specifies the gravity constant which influences the
- roller coaster's speed as it moves on inclined track.
-
- G. Supports:
- --------------
-
- This specifies whether the ground supports are to be drawn.
-
- H. Flags:
- -----------
-
- This specifies whether flags are to be drawn on the sides of
- the track.

-
- Ordering:
- =========
-
- Supercoast is a shareware program. This means that the
- unregistered version is freely distributed, but users are required
- to purchase a registered version to continue using the program. As
- stated in the setup dialog, to order, send a $10 check or money
- order payable to Brian Skrenta to the following address:
-
- Brian Skrenta
- PO Box 2623
- Columbia, MD 21045
-
- For this registration fee, you will receive the latest version
- of Supercoast. This version will include options for password
- protection, and different track designs. It will also enable you
- to make your own roller coaster designs for use by Supercoast.
- This registration fee will help the author (Brian Skrenta) to make
- improvements on Supercoast and develop other shareware programs.
-
-
-
- Distribution:
- =============
-
- The unregistered version of Supercoast may be freely
- distributed by anyone provided that the following conditions are
- met:
-
- 1) None of the program or files are modified in any way.
-
- 2) The files scoast.scr, scoast87.scr, and scoast.txt must all be
- included in the distribution. Feel free to use any
- archive/compression format for these files, but it's probably
- easiest just to use the original zip file.
-
- 3) Do not charge more than $5 for the media that the program is
- sold on.
-
-
- Please do distribute this program!!!!
-
-
-
- The registered version of the program is only for use by the
- registered owner and is not to be distributed under any
- circumstances.
