Note! Abandoned page! This page has not been updated in quite some time. This is not due to not updating the code and writing new one, but to problem uploading to this site. You will find many of my recent uploads at the Lightweight IDE pages. There you will find: Lightweight IDE (with source-code) TransSkel version 4, a fully modernized version of the good, old framework. The new Sprite Animation Toolkit is or will be available there. OpenGL demos in C and Pascal. I hope I will be able to upload PasCocoa code soon. and more. You will find that I no longer write for neither Think Pascal nor CodeWarrior. That is because I have moved to FPC and Lightweight IDE. I still think Think Pascal is a fabulous development system second to none, and CodeWarrior is prefectly decent with superb cross-language integration, but I had to move on and find other solutions. From here and on, the material is dated and not updated:
Ingemar's Corner At ftp://ftp.lysator.liu.se/pub/mac/source/, I keep an archive with many source-code demos that I have written or modified. Most of it is in Pascal, since that's where the efficient programming is: readable, superior string handling, very fast compilation, just as fast resulting code as any high-level language and even as fast as a certain glorified assembler that some people like. Those who like write-only languages are free to use them, but I support what I believe is best.
There are plenty of demos in the Lysator archive. Near the source folder, you will find the SAT (Sprite Animation Toolkit) archive, which also holds tons of useful source. However, all that depends (more or less) on the SAT library. What you find in the source folder is stand-alone stuff.
Some demos are good, some not quite so good. Some are well documented while others are rather quick hacks. Most of all, some are very useful while others are at best nostalgic or curiosities.
DISCLAIMER: If you run into trouble, by all means ask, but don't demand support and lots of help from me. My time is often limited. I will help if I can.
COMPILER:
With what compilers does the demo run without modifications? Note that the CodeWarrior projects are usually for old versions. If no CodeWarrior project is included, the source probably won't run without at least adding a couple of Toolbox units in the "uses" clause and adding "qd" before all QuickDraw globals (e.g. screenBits), but it generally isn't much more than that.USEFULNESS:
Why would you want it? A rating from one to five stars is given in two classifications: beginners and experienced users (people who know the common methods but can use some help with certain problems). If I would put it in the hands of a beginner that I want to teach programming, it gets a high "beginner" rating, and if I feel that I might look it up myself some time to see how I did it, I give it a high "experienced" rating. NOTE: The ratings are for pre-OSX times. Anything that is not Carbonized has limited usefulness and requires some work to use with OSX.SOURCE:
Where did I get it and what did I do (if I remember right, that is)? This isn't extremely interesting for you as a user of the demos, but i feel that if I modify someone else's code, the original author should always get credit for the work.Notes on Think Pascal versions:
Most demos come with Think Pascal projects (and often also CodeWarrior). Note that the code is written for Think Pascal 4.0.2 with old interfaces, not the newer UPI interfaces (which are available as a separate download, and also come with Think Pascal 4.5d4)! These new UPI interfaces are, sadly, NOT easy to use. They have unnecessary declarations that conflict with the built-in ones, have lots of unnecessary dependencies that forces you to include tons of interface units that you really shouldn't need. There is hope for a better version (I am working on it), but my recommendation for now is to use the old interfaces, possibly with glue code like InterfacesUI.p to ease portability to CodeWarrior (so that you can use CW to compile a PPC version).
Latest additions:
- Skel 3.0x, Carbonized!
- TransSkel Pascal 2.7a, Carbonized!
- zlib 1.04 for MacPascal, data compression library
- rwBinHex, another stand-alone unit for Binhex encoding and decoding
- BillHex, a stand-alone decoding unit made from Bill Catambay's DropBin
- OpenGL for Pascal
A 3D library with full C code, written by Sergei Savchenko. Well, it is really rather a polygon rendering demo, with portability being the strongest point. Unlike most other source here, it is in C.
Shall we port it to Pascal? Can we do that and keep it portable? Or build a Pascal interface... but that would have the same problem.
COMPILER: Think C and CW C (recommended).
USEFULNESS: For drawing textured polygons, possibly for building a simple 3D engine on.

carl-o-term.hqxTerminal emulator. It is primitive, but it works, and is even a bit elegant with those small buttons in the corner. It uses the low-level serial driver, which I wholeheartedly recommend over the buggy and unreliable Communications Toolbox. (You should use the latter only for reaching othr ports than the standard two.)

Cellusoft-Demo-plus.hqxMy improved version of Tony Small's "Eyeballs" sprite demo. Not exactly an easy start to sprites, but his way may be interesting to see. The big difference to Micro Animation and Offscreen Toys is that it loads its sprite faces from a few PICTs rather than "cicn"s. This speeds up loading a lot (see also FastLoad.p in SAT), but is much harder to handle. This demo uses hardcoded constants for the positions in the PICTs, which I'd say is the worst way to do it. (Sorry, Tony!)
This code is shareware, according to Tony's comments. My minor changes does not change that. However, don't blame Tony for the changes I made!
COMPILER: Think and CW.
USEFULNESS: Offscreen techniques, sprites from multi-face PICTs.
Novice: **

SOURCE: Somewhat improved demo originally by Tony Small.
CollectPictColors.hqxDemonstrates two ways to extract the colos from a PICT. This is very useful if you want your program to adapt the 256 color palette to graphics. I used it in my game Christmas'95.

ColorIcosahedron.hqxAnimation of a 3D icosahedron. This isn't real-time 3D; the icosahedron is pregenerated in a couple of positions. The most interesting parts are the offscreen drawing and the custom palette. I don't think I'd use the 3D parts for anything else.
COMPILER: Think.

IngisWDEF-13.hqxIf you asked me to pick the best gem in the collection, this is the one I'd choose. Ingis WDEF is a package for making custom window definitions (WDEFs) with arbitrary shape. I have used it myself for making the hexagonal window in the games Hexmines and HexReversi, for making the circular window in the NewWatch demo, and for making the special "document" and "baloon" windows in my 3D puzzle game. What is so great about it is that it is so easy to make a new one! You can make windows with holes, windows that aren't in one piece, anything!
The ease of use is achieved by isolating "stubs" for just about anything you would like to change in a separate stubs file, and keeping all the reusable code in files that you almost never change. You just duplicate a demo and hack the stubs file.
I don't claim that it is 100% perfect, though! It has the same limitations as all code resources. I don't use any global variables, for example. The coloring rules for other windows are not applied to Ingis WDEF. It doesn't adapt when overlapping several screens.
I believe I used so much sweat in making this work and making it useful, that I deserve credits in case you use it. (That holds for all source demos out there, mine and others, but this was more trouble than most.)
HIGHLY RECOMMENDED!
COMPILER: Think or CW.
USEFULNESS: For making arbitrarily shaped windows.

SOURCE: Original code.
InterfacesUI.pA compatibility file for Think Pascal, to let us TP4 users use the new routine names without using the real UPI. The problem with the "real" UPI is that the interface files have more dependencies, so you tend to include tons of them where you previously just needed a few. For example, try including QDOffscreen.p and see how much you need to add. I prefer just using this file, with the differences. It covers most cases, and what it doesn't cover, I can {$IFC}.
COMPILER: Think.
USEFULNESS: If you use Think Pascal without UPI, but want that same code to run with UPI (for example when building the PPC version in CW).

LabMouse.hqxSource code to an unfinished first-person... sorry, first-rodent 3D game I was working on a few years ago. I gave up since the engine got too old-fashioned and I wanted to move on to more modern techniques. I didn't even bother to make any serious graphics for it, as you can tell when playing it.
Pity on a neat idea. It is a lot of source in this archive, and you can find many useful sub-parts. You can use the game engine to make simple 3D mazes. It is possible to make a shooter like Wolf3D with it, but I'm not sure if it is worth doing today.
Note: Not available by ftp, only by http!
COMPILER: Think and CodeWarrior.

madf-lib-35-pascaltp.hqx MADH-Library-42-Pascal.hqx MADH-45-Pascal.hqxPascal interface to the MADF/MADH music drivers, version 3.5 to 4.5. I ported 3.0, but consider that obsolete. Matthias ported 3.5, and I added Think Pascal compatibility. Federico Filipponi made the Pascal interfaces for MADH 4.2 and 4.5, but there is no Think Pascal option since there is no Think C version of the libraries. You may also want to consider MIDI, using QuickTime. See Piggy.

Maze-generation.hqxThere maze generators we have seen lately have had stack problems, due to using recursion. I wrote Maze-Ingis to show that we can handle it by keeping track of the stack usage. But, hey, why were we using recursion at all for such a simple problem?
I stumbled over a post in comp.lang.pascal.misc by Derek T. Asari. The post included a demo maze generator that was marvellously simple. Both the source (disregarding comments) and the compiled application are less than 2 kilobytes each! I Macified it a bit and commented it so that it will make some sense to you.
COMPILER: Think.
USEFULNESS: Probably the simplest maze generator you can find, which makes it ideal for using in a maze-using game - definitely better than Maze-Ingis.
Novice: ****

SOURCE: Based on a Pascal demo posted to comp.lang.pascal.misc.
Maze-Ingis.hqxThere was a thread in the Mac Pascal mailing list about programs that use lots of stack, due to deep recursions. One of the problems involved was a maze generator by Robert Dell, later released on the net as Maze Maker. Although Maze Maker is fast and works well, I found it unnecessarily demanding for the problem. I wrote Maze-Ingis aiming for simplicity and low demands on memory and stack.
However, there is a much simpler solution. See "Maze generation" above.

MicroAnimationDemo.cpt.hqxThis is a demo I wrote for the "Tricks of the Mac game programming gurus" book, but that was never used since I didn't write that part of the book. It is also an afterthought to Offscreen Toys; Offscreen Toys got so good that the simplicity was lost. MicroAnimationDemo is minimal, just a few lines of code if you disregard the conditional compilation and all the "uses" that CodeWarrior wants. RECOMMENDED FOR BEGINNERS.

ReqVidPas-11.hqxNew version of my Pascal conversion of the Apple demo "Request Video" for Display Manager. This has been requested more than once in the Mac Pascal fora. This new version supports PPC and fixes some rather important bugs affecting older systems.
This code will let you change the resolution of your screen. Please do not confuse this with the much simpler screen depth calls (SetDepth). Also, don't expect it to give you exactly what you ask for ­ always check if you can use what it gives you.
COMPILER: Think and CodeWarrior.
USEFULNESS: To change the resolution of the screen.

rwBinhex.hqxI wasn't satisfied with BillHex. BillHex was a nice decoding unit, but couldn't encode. OK, perhaps I could just have figured out encoding myself, but why do that when there are many people who did that before? So I found Roy Wood's source and rewrote it quite a bit. The source is still C, but it is useable from Pascal as well. It doesn't depend on any other libraries, and has a very tight interface. Probably your best pick for adding Binhex capability to your application!
COMPILER: Think or CW, Pascal or C.
USEFULNESS: Binhex enconding and decoding.

SOURCE: Highly revamped old demo.
QD3D-PInterfaces-10d2.hqxPreliminary Pascal interfaces to QuickDraw 3D - at last! Note that it is preliminary, probably buggy and somewhat incomplete. Three demos included. You need the QD3D development kit to use it.
Note: Apple has released their own QD3D interfaces after I released this, so I guess this is obsolete now.
COMPILER: CW (PPC required).
USEFULNESS: If you want to use QD3D from Pascal, this is what you need!(But I'd use Apple's version if I could find it.)
Novice: **
Experienced: ****
SOURCE: Converted from C code in Apple's QD3D SDK.
SavePICT-FKEY.hqxFKEYs are small programs attached to command-shift-number keyboard combinations. If you havn't been into Mac hacking as long as I have, the concept of FKEYs may be unknown to you. Very few, if any, FKEY source-code examples are available, so I decided to do something about it.
COMPILER: Think and CW.
USEFULNESS: For learning how to make FKEYs.

ScreenDump.hqxScreen Dump is a DTS snippet converted to Pascal.
COMPILER: Think.
USEFULNESS: Using GetPICTInfo and grabbing screen dumps.

SOURCE: Converted DTS demo.
SegLoadPPC.hqxImplements the Segment Loader calls for native PowerMac code. Pointless? No, it is not. Making simple on-shot drag-and-drop applications is very easy with Segment Loader calls, and much more complicated with the modern way, Apple Events. By hiding the Apple Event code in a reusable unit, the PPC native drag-and-drop programs can now be as simple.
COMPILER: Think or CW. (Hardly meaningful for TP.)
USEFULNESS: For making simple drag-and-drop applications.

SetMouse.pSets the mouse position by drawing into low-mem globals.
COMPILER: Think. (No project included.)
USEFULNESS: Good for certain games. Might break under future systems.
Novice: **
Experienced: ****
SOURCE: I think I got it from Jonas Wallgren, who didn't like an older SetMouse I found on the net and posted...
SlotVBLTest.hqxRuns a SlotVBL task. I made it for use with SAT, but it is generic enough for any VBL-synching problem. It is compatible with old non-color Macs as well as PowerMacs. This is a must-have for anyone interested in how to do VBL.
HIGHLY RECOMMENDED!
COMPILER: Think and CW - including PPC!
USEFULNESS: For synching graphics to the CTR beam.
Novice: *
Experienced: *****
SOURCE: Based on two VBL snippets, one in Pascal and one in C, but I guess we could consider it original.
skel-30i.hqxOne of the oldest program skeletons around, slightly modernized. It "does nothing, but does it well"! I prefer TransSkel though.
COMPILER: Think
USEFULNESS: For learning the basics, and for using as a base for building applications on.
Novice: ****
Experienced: *
SOURCE: Converted from C, which was once converted from Pascal. :-) :-(
Skel30x.hqxSame as above, but now Carbonized. It "does nothing, but does it well"! I prefer TransSkel though. A unique feature with this demo is that it also works under Think Pascal.
COMPILER: CodeWarrior (required for native OSX) or Think
USEFULNESS: For getting started with Carbon, especially if you want to keep using Think Pascal as prototyping/debugging tool.
Novice: *****

SOURCE: Converted from C, which was once converted from Pascal. :-) :-(
sndDemo.cpt.hqxThis is a sound demo that was posted to the net long ago. I polished it a bit and compressed the sound, in order to make it less tedious to download. I find it unnecessarily complex. See Three-D Bouncer for a more interesting sound demo.
COMPILER: Think and CW
USEFULNESS: Asynch sound playing.
Novice: **
Experienced: *
SOURCE: Somewhat improved demo by another author.
SpanBuffer-Mac.hqxThis is a demo written by mr Abrash for Dr Dobb's Journal, that demonstrates the span-buffer technique for 3D rendering. I'm not sure if this is really interesting any more, in the days of 3D accelerators, but it performs pretty well on an old 6100. The code is mostly C.
COMPILER: CW.
USEFULNESS: For 3D engine makers.

SOURCE: DJGPP code converted to the Mac.
SWar-p.cpt.hqxThe original author wanted to write a SpaceWar, but never completed it. It is pretty neat, but a bit primitive with only eight directions.
COMPILER: Think and CW.
USEFULNESS: It is a good start for a not too hot game. I'm sure there are a few things in it you may like.

Text-to-STR-list.hqxThis is a programmer's utility, a drag-and-drop application that converts a text file to a STR# resource, making each line a separate string.
COMPILER: Think.
USEFULNESS: As it is. Useable as shell for very simple drag-and-drop applications.
Novice: ***
Experienced: ***
SOURCE: Original code.
three-d-bouncer.hqxA demo with a simple (flickering) 3D animation, with stereo panning sounds. The graphics are pretty awful, but the sound parts may interest you.
COMPILER: Think and CW.
USEFULNESS: Mostly as sound demo, but also a little graphics and animation.

SOURCE: Converted from a screen saver module.
TransSkel-Pascal-26.hqxThis is an improved version of TransSkel Pascal, a good library for simplifying the event processing parts of Mac applications. This version has MultiFinder event and Apple Event support. Version 2.6 adds full PPC support with Universal Interfaces rather than MPW interfaces.
If you find Mac applications complex, with all details in handling menus, windows, events etc, try TransSkel!
RECOMMENDED!
COMPILER: Think and CW.
USEFULNESS: Event loop and lots more for any GUI application.
Novice: *****
Experienced: ****
SOURCE: Refurbished Pascal code.
TransSkel-Pascal-27a.hqxPreliminary version of the next TransSkel Pascal, now Carbonized, that is OSX native! Apple Event support is finally complete.
COMPILER: CW Pro 5 to 7. CW Pro 6 was used for making it.
USEFULNESS: Event loop and lots more for any GUI application.
Novice: ***
Experienced: ****
SOURCE: Refurbished Pascal code.
Turbo3d.hqxThis is old demo code that I seem to have forgotten to put here. It is two old demos from Turbo Pascal for the Mac, demonstrating how to use Graf3D, Apple's old 3D library. No texture mapping here, just line art. Hey, Graf3D was hot in 1984! I've also made a variation of each, one with color and one with off-screen buffering to eliminate flicker.
COMPILER: Think.
USEFULNESS: Fundamental graphics. Simple 3D. Off-screen buffers.

Ultimate_Button.hqxSource to a very flexible CDEF (control definition). It can be very useful when putting the final touches to an application, where you aren't satisfied with the controls you use.
COMPILER: Think and CW.
USEFULNESS: To use for special controls in your own applications, or for making your own CDEFs.

zlib-104-for-MacPascal.hqx"zlib" is a free compression library written by Jean-loup Gailly and Mark Adler. I have adapted it in order to make it usable from both Think and CW. Perhaps even more importantly, I have made two new demos, Dropgz and zResource. Dropgz is a drag-and-drop gz compressor/decompressor. zResource is perhaps the most interesting one, a very slim API (only three calls!) for resource compression/decompression that you can easily plug into your application in order to ship it with large resources compressed.
COMPILER: Think or CW.
USEFULNESS: To incorporate decent compression into your programs, either for files or for resources.

ZoomFKEY.hqxSource to an FKEY that makes a "zoom" effect towards the current cursor position. This was posted by Matt Mora. I made some quick fixes and added a Think Pascal project.
COMPILER: Think.
USEFULNESS: Learn zoom effects and FKEY programming.
