Unchaos for Mac

by rennie moffat · in iTorque 2D · 07/11/2010 (7:25 pm) · 12 replies

Hi,
I am simply looking to optimize my game, and I understand that Unchaos is good as it groups images onto a single sheet, maximizing loading time efficiency. I work on a Mac however and am unable to open and work with Unchaos as provided by iTGB. I am wondering is there a comparable program for Mac users?

Unless someone on the team miraculously finds free time, there are no plans for a Mac version of Unchaos. However, you can accomplish the same end result with other tools, including Gimp or Photoshop. It's just a more manual process. I'm sure ther are other automated tools out there, but my first alternative would be to use Gimp and calculate the source rectangles using the pixel measurements.

Great, Thanks Michael.



Nice new pic. Oregon? California?

@Rennie - Thanks. California's Redwood National Park. Trees were massive.

Swweeet.
I went thru BC's rain forests, and the trees were epic there too. I remember I once saw one huge one, growing in the stump of another GIGANTIC one. Holy shmorgasborg.

You can get Unchaos running on your Mac using Crossover (I posted on here about this in another thread). Apparently you should be able to use Winebottler to run it as well, which would be better as Winebottler is free, but I couldn't get that to work.

Hope this helps - good luck

@Seb,
I have used both Crossover and WineBottler to use various PC programs, but both, I felt were glitchy and problematic.


Thanks tho. When/if needed I will try Dean's and Michael's approach.

Cheers.

The only really solid alternative I so far found is http://zwoptexapp.com/

It "unhappily" costs (a mere $25 bucks) but is hell fast and its capability to remember what images are in to update the sheet from the corresponding source images without fucking up the layout is a serious gain :) also it throws out a plist (->xml) so really iphone -osx friendly

How essential is source rects?


As in, is it only needed/is a good way to save memory? Increase load speed?

Marc, that looks like an interesting app. I will check it out.

Rennie, source rects are only useful if you have a bunch of images of different sizes and you want to store them all on one image sheet. You can then create a single POT image, comprised of many different sized sprites, and you can then PVR them. Source rects provides a mechanism for extracting individual images of different sizes. It's basically a sprite sheet containing sprites of different sizes.

Personally, I only have one image that uses source rects. Most of my images are comprised of sprites that are the same size (either 32x32, or 64x64), so I pack those into a CELL image.

Not sure if source rects is a standard in the industry or not, so I always try to make my sprites all the same size and use CELLS. I'm pretty sure that most gaming engines will support CELL and KEY, because people have been using those methods for years.
