Windows Oni vs. Mac Oni

This page contains information that is out of date. Please update this information to reflect where the community is at today.

There are no significant gameplay differences between the PC and Mac versions. However, the following information is important for all who hope to mod or script Oni in a way that is Mac-compatible.

PC exclusives

Bindable events

Everything that has to do with cutscene authoring (recording character movements), and probably a little bit more.

BSL functions/variables

The PC build is probably older, and so it has a lot of "dev-and-debug" functionalities that were not used by the original script logic. When the Mac and PC demo releases were built, some of those features were completely left out. HERE is the full list of commands and variables that are unavailable on Mac or PC demo (by order of appearance in script_commands.txt). While some of them may be obsolete, and thus may have little effect on PC, a lot of them are definitely not defunct, and their lack on Mac is a major limitation. For instance, one should note :

• the absence of dev-console-related commands (the Dev Mode, however, is available on Mac and PC demo : just somewhat limited)
• the absence of chr_location and chr_location_settocamera. The placement of characters is thus limited by the original set of "teleport" flags.
• the absence of chr_focus and sc_focus. Thus none of the following is scriptable on Mac as of today :
  • shapeshifting bots and Tag mode in Oni Team Arena
  • squad gameplay
  • intermittently "switching" to characters that are NPCs in the original logic (used in a few mods e.g. Loser's Warehouse)
• the absence of chr_health, wp_reset, and a few other commands/variables that make scripting more flexible.
• other stuff I'm forgetting (there's quite a lot missing, really)

For further information, here are the complete lists of commands/variables as obtained with the dump_docs function call :

• script_commands_Mac.txt
• script_commands_MacBeta.txt
• script_commands_PC.txt
• A comparison of the commands/variables side by side, PC, Mac, and Mac Beta

As for the effect of the commands and variables, the best documentation so far is on ssg's Oni Stuff. It covers the full list of commands/variables, i.e. that of the PC version. Porting it to Oni Galore, slowly but surely...

Mac exclusives

A semi-official patch

Made by OmniGroup, Oni 1.0 v1.36 (native OS X port) fixes a few issues with sounds, mouse, rendering, AI... On the whole, the Mac build of Oni may have fewer crash issues as a result. For more information about installing this one on Mac, see here

Startup GUI

If you press Shift while starting Oni (This only applies when running in OS9 or Classic, not OSX), a little GUI will pop up and let you do the following :

• configure controls LH and RH
• set command-line parameters (Args:)

Other differences

Level logic

The contents of the IGMD folders are exactly the same on Mac and PC, except for tctf_ii (CHAPTER 13 . PHOENIX RISING); these changes were made in the logic of the boss battle and cutscenes:

• Differences in tctf2.bsl
• Differences in tctf_ii_cutscene.bsl

The global folder is not recognized by the PC demo and Mac PPC engines, but is by the Mac Intel build from Feral.

File formats
