GameMaker Info

Latest Version: 3.9.9
Release Date: 1/17/08
Minimum Requirements: MacOS X 10.1 or better

What is GameMaker

GameMaker is an easy to use card based development system which allows you to create adventure games with graphics, buttons, and text. There is no programming required, but it does have a scripting language which can be used to make better games. For beginners, just draw some pictures, type some text, click a few buttons, choose some options... and an adventure game is created! When you are ready to get more advanced, you can add some additional features to your game by using the simple scripting language to use sprites, play movie files, do actions based on player choices and variables, etc. You can then compile your game into a real application that you can upload and let others download and play. There are no royalties to pay, so make as many games as you like.

GameMaker received a 4 cow rating at TUCOWS.com

Help & General Questions

If you're experiencing bugs or problems with GameMaker, first make sure you're using the latest version. See the Latest Updates section to download the update patch for your version.

I downloaded GameMaker, but It says I need an application to run it.

GameMaker is a Macintosh application and requires the user to have an Apple Macintosh computer. It will not run on any version of Windows. Previous versions of GameMaker were compressed as StuffIt archives (.sit file). StuffIt is the older Mac standard of compressing files for the web before OS X came along. You can open those compressed archives using the free StuffIt Expander which you can download from http://www.stuffit.com/mac/expander/download.html

Is there a Windows version of GameMaker available?

No. There might be one at some point in the future, but there isn't one at this time.

I'm a registered user of GameMaker 2.x. How do I get v3.x?

GameMaker v3.x is a $5 upgrade for registered users of v2.x. Since the upgrade fee is so low, we can't accept payments through kagi, but you can send a check or Money Order directly to me or you can use PayPal.com to order the upgrade online. See the Ordering GameMaker section above for information on where to send the upgrade fee.

I'm not a registered user. How do I get the full version?

See the Ordering GameMaker section above.

Why should I register?

Once you become a registered user, I will send you the latest full version of GameMaker which lets you have up to 500 lines of code per script (the unregistered version is limited to 15 lines of code per script), removes the nag windows that asks you to register, and can compile your games into real stand alone Mac applications that can be run without the need for GameMaker or any game player type of program.

Can I get the full version for free?

No. Please don't ask me to send it to you for free. I can't accept software trades either. I'm not trying to be mean to you, but I spend a large amount of time and my own money to constantly update this software and provide support for it.

Can I charge shareware fees for games that I make?

Yes. If you are a registered user of the full version, you can charge fees for your games. You can send your games to anyone or upload them to any internet location or online service that allows uploads. However, you are NOT allowed to give away or charge money for GameMaker itself.

How do I use the inventory, status bar, midi files, counter, any other feature?

There is a new GameMaker Guide web page that discuses various features. Please visit the GameMaker Guide page to see if your question is answered there.

Can v3.x open documents created with a previous version?

GameMaker v3.x can open game files made with any version of GameMaker as far back as v1.5. If your game was made with a version of GameMaker older than v1.5, you may need to use the GameConverter application to convert the game file to at least v1.5. Once you make changes to the file with GameMaker v3.x, you may not be able to open it with any earlier versions.

Do I need other software to run GameMaker or compiled games?

No. GameMaker is an application. No other software is needed to use GameMaker. Games created with GameMaker can be compiled into stand alone applications so that no other software is needed to run them.

Application I created won't launch or shows wrong icon

In some cases, after creating an application, you may need to close the folder and reopen it for the Finder to properly recognize the new application. If that doesn't work then you may need to rebuild the desktop. To rebuild the desktop press the Option & Command keys while restarting your computer.

GameMaker or games created with it crash on my Mac

Older versions of GameMaker and games made with older versions may not run correctly with recent OS updates. Make sure you are using the latest version of GameMaker by downloading the latest update patch. If you are already using the latest version and still experiencing problems, please report the problem here. If you're trying to play a game that was created by someone else, try using the GM Old Compiled Game Updater to patch the game engine to a newer version or contact the author of the game to see if a newer version of the game is available.

I can't run GameMaker because it says I need CarbonLib. Where do I get that?

For OS 8 and 9, GameMaker requires Apple's CarbonLib extension v1.6. You can download the free extension from Apple's web site at: http://docs.info.apple.com/article.html?artnum=120047. Note that the latest version of GameMaker will not run in Classic/OS 9 and older.

Late Breaking News

The notes below are for GameMaker v3.9.9. If you're using an older version, please get the latest update here.

07/01/08 - Line of code after END REPEAT is not being run unless the REPEAT loop is inside an ON event structure. Work Around: If your REPEAT/END REPEAT loop is not inside an ON MOUSEDOWN, ON MOUSEUP, ON TIMER, ON KEYDOWN structure, then leave a blank line of code after the END REPEAT line. Status: Bug is confirmed. Looking into the problem.

06/17/08 - Using a semi-colon at the end of a PRINT command can make text on the card disappear. This happens only in compiled games. Status: Fixed for the next update.

06/17/08 - REFRESH TEXT does not refresh the card text if the card did not have any text showing to begin with. This happens only in compiled games. Work Around: Use CLEAR TEXT if you want to erase all card text. Status: Fixed for the next update.

03/12/08 - Attempting to display sprites numbered from 10 to 20 may not work in compiled games. Status: Fixed for the next update.

Known Issues For All Versions

Version 3.x may still have some problems when encountering a full disk (unconfirmed because we haven't been anywhere near having a full disk in several years). It is highly recommended that you use a Hard drive with at least several Mb of free disk space and always keep a backup copy of any game you're working on.

There is approximately a 16Mb file size limit for GameMaker files. Creating a project that is larger than 16Mb can cause GameMaker to crash. This is a Macintosh resource file limit so I can't fix this easily. Future versions will eventually use multiple data files to correct this problem. If you are experiencing a disappearing card picture, then you've probably reached the file size limit. Try using GM Toolkit to compress your game pictures or use external graphics files with either the IMAGEFILE or SPRITE commands.

GameMaker will not run on locked or read only media such as a CD. If you recieved GameMaker on CD, drag the entire folder to your hard drive and run it from there.
