Safari
version 2.4.2
Written by: John Gallaugher
Ported to CW by: Paul Celestin
This simple application does nothing but display a simple clock in
a rectangle on your display. You can move the clock around, and you
can also check the date by clicking once on the clock.
941207 - 1.1.3 initial release
951215 - 2.4.1 updated for CW7
960704 - 2.4.2 updated for CW9
---------------------------------------------------------------------- */
/*
Code release for Safari II 1.1.3
Changes since 1.0 release:
It's now FREE! (please send comments & a postcard)
The sicn's were eliminated from the apple menu so it should now work on older systems
The dialog box in which I begged for a job is gone (I've found work, thanks!)
The option to 'score when hit' in rectangle surrounding animal now works.
There still seems to be problems with the sound playing on older 68000 Macs. Any advice on
this problem, or more descript diagnoses would be appreciated.
SAFARI II © 1991 by John Gallaugher
A program written in Think C. Portions copyright Symantec and Apple Computer.
In 1985 I wrote a program called Safari to try to teach myself the Macintosh toolbox.
The original Safari was simple and cute, but it was also a program which doesn't work on
today's machines. Safari II is an update to the orginal Safari. It should work on all
Macs with at least 1 meg of memory running system 6.0.x or greater.
Although I have done quite a bit of Macintosh database development, I have never programmed
professioanlly in the toolbox or in C. As such, please excuse the clumsiness of some of
this code. I am distributing the source code and game for free in hopes that it will help
others learn some of the basics of Macintosh game development. My experience has found that
there's not much free source code out there to help the would-be game developmer. I hope my
modest submission helps some folks get started.
Although this product is offerd for free, I DO ask those pros and semi-pros out there to
offer suggestions on how I can improve this code. Since I'm pretty green in toolbox coding
I would greatly appreciate advice. Please don't hold back, criticize me to the hilt!
I need and welcome the help.
Also, please don't distribute any modified versions of Safari. I welcome you to learn from
the code and encourage you to produce original work, but I would like all updates of the game
to pass through me.
Lastly, please send comments! I love to hear from folks who have received my game.

A special thanks to the helpful folks at the Boston Computer Society's MacTech group, and to
the outstanding faculty of the Boston College Computer Science Program for their patient help
in answering my silly questions.
This program seems to work fine on my 4 meg LC running under System 7.0 if you run into any
problems, PLEASE let me know.
RESOURCE NOTE: All sounds were created using the microphone on a Macintosh LC.
All pictures were created using MacPaint. The 'RGN ' resources which are used to detect
the boundries of the animal bodies were created using a utilty program called 'Regions'
created by the late Duane Blehm (it should be available via local user groups and on-line
services). All other resources were created directly in ResEdit.

increaseSpeed is true when Game Options dialog has the speed of the game

easyShoot allows player to score by clicking in a rect surrounding the animal
instead of clicking directly within outline of the animal (good for kids).
loopValue keeps track of a group of statements which mimic a for loop, but which
increment only once every pass through the animation procedure. This is done
instead of a for loop so the game can respond to an event after each animal
is drawn.
