UPDATE: Apple has just approved and Particle Playground v1.1 is now available in the Mac App Store.
Yesterday I uploaded Particle Playground v1.1 for Apple to review. I have been working on v2.0 but I received a mail that landscape support was something that was being looked forward to, so I decided to release an intermediary version with just a few new things.
Today Particle Playground was released on the Mac App Store. Since there is only one default particle emitter image included I thought you might be interested in the other particle images I used to make the screenshots for the Mac App Store.
I am so excited! Apple just approved Particle Playground and I set things up so that it will be available tomorrow (February 15th). There will be a 50%-off sale for the first two days. So it will cost 4.99$ for the first two days and 9.99$ after that.
You can read what I blogged about UIKit particle emitters in my recent posts or check it out in the Mac App Store.
I hope you enjoy PP as much as I enjoyed creating it and hopefully it soothes your pain as it did mine.
While developing my last app I got the idea to add some sparkle to it. But since I’m not using cocos2d or some other framework I had to use the standard iOS classes CAEmitterLayer and CAEmitterCell to set-up my particle emitter. After a while I started to grow tired of the hassle of always tweaking the emitter the tiniest bit and then recompiling and running the app in the simulator.
UPDATE: Here is the Particle Playground savefile for this emitter so you can also check it out in Particle Playground.
I recently spent a lot of time working with
CAEmitterCell. After a while I stumbled upon one curious thing. The particle image you use in your
CAEmitterCell gets mirrored horizontally.
I just stumbled upon a nice feature in Spotlight. You can input formulas into the Spotlight search bar and it short-circuits to Calculator and displays the result in the spotlight search results.
It even supports log(x), ln(x), exp(x) and I guess a lot more functions I just didn’t think of when testing this for a bit.
Quite a handy feature I would say and one I have never seen before. But after googling for three seconds I found about a myriad posts about this. So I guess it’s yesteryears news. It still felt right to slap it up here. Maybe you didn’t know it either or maybe I will forget it again in a couple of months and this will be my reminder. 🙂
Since I am in the process of finishing my first Mac App now is the time to create the image resources for the app. Along comes the old problem/annoyance of manually resizing and renaming app icon files. After a little googling i got some solutions but most of them were just for iOS, so I had to adapt one of them to my needs.
