Mac

Oni crashes on G5 Macs.

In one case, the reason for the crash was that Oni was set to a 640x480 resolution. Changing it to a higher resolution solved the problem.

How do I change the resolution when Oni crashes at startup? Use the program Oni Save Game Editor to change the resolution.

Oni crashes on IntelMacs

It appears that the crash is due to a text overflow in a fixed-sized buffer. This occurs when Oni is listing all the GL extensions of a video card before writing it in the startup.txt file. A hack was made to make make Oni think that the video card does not support the GL extensions.

So far, no one has seen any difference in the graphics due to this unofficial hack. The modified version of Oni OSX can be downloaded here

There was an interesting comment on the Apple discussions board dated Sep 11, 2006 that a Universal Binary (compatible with IntelMacs) of Oni will be out soon...

Other issues

In Mac OS X the character cannot fully turn or rotate around. Its like the mouse tracking has hit a boundary or the edge of the screen.

According to Feral: "Mac OS X does not support Input Sprockets, which Oni needs. Run Oni in "Classic" mode to avoid this problem. Alternativly, download the OmniGroup's Oni port and try your luck with that."

The Mac release has a few issues, check out the following :



PC

There are a lot of reasons why the PC (Win32) version of Oni can go completely crazy. The single most common symptom is that Oni's window will go blank, and in the middle of your screen you'll have

(There are other crash messages, but I'll detail them later : if you do something and get another crash message than that one, just don't do it.)

There are several occasions on which Oni exits with such a message, with a more or less good reason to do so. However, when it "blam"s at startup and doesn't let you play the game, that's a bit annoying. Unfortunately, that's exactly what happens with an out-of-the box installation of Oni on modern PC rigs (Windows XP + recent GFX cards). Why does that "Blam" happen? (and why does any "blam" happen?) And, more important, what do we do about it?

HERE YOU GO

For any other problem, see below.



Other problems

Texturing

There are several degrees of severity (from crappy textures to ugly textures to OMFG). That's always a driver issue.

Old drivers

Try and get a recent driver for your GFX card (upgrade to Catalyst if you have an ATI, etc)

New drivers

Sometimes, Oni is uncompatible with modern stuff. Try and get a really old driver, then :)



Major lag

Power management

This can be a problem on notebooks. Under certain conditions, the performance of the computer will decrease dramatically, for example :

  • if you run on battery power
  • if you let the computer overheat

Driver issue

Same as "texturing", see above.



Widescreen

Not really a problem, but it can be a bit annoying when your ONI window gets auto-stretched to fit a 16:10 screen.

Solution
Run ONI with the -noswitch command line argument. Oni then runs in a "window" in the upper left corner of your screen, with the resolution selected in Options.
If you want that window centered with a black background behind it, use OniWindowMover.



Game plays funny

For example, you may run Oni for the first time, and then there's this room with a data console on this side and one on the other (nothing happens when you activate them), a window and a door on the other side... and an invisible wall in the middle of the room that doesn't let you through to where the door is, and that you can do nothing about. What the... LET ME OUT!!!

That's not a sick puzzle... just screwed-up (or absent) level logic.

I don't know where you got your copy of Oni, but your installation folder (say, "Oni") should contain another one called GameDataFolder, and in this one, there should be another one called IGMD.

That's where the level logic is defined, level per level. If the contents of this folder is missing or corrupt, nothing interesting will ever happen :)

So you may want to :

  • check for that folder in your installation... and give me a copy. I'm just curious about what happened to it.
  • download that one (PC) or that one (Mac) and unzip it into GameDataFolder.

It should work.
