2012

I was asked today about how to disable the home button on an iOS device. I didn’t think it was possible to do so, but a little snooping around and I found that it was. The context of the conversation was that schools have been reluctant to use iPads because they couldn’t be used for ...

2012

My latest attempt is to extend the Cocos2d particle system to include a variety of things, multiple particle sprites, animated sprites, flow fields, and eventually a boids algorithm implementation.

I promised in the comments a few days ago that I would post how one would go about saving a photo using the program I created in the last Core Image post. We’re already passing the video feed into a CIImage before we write it to the screen. All we need to do is take ...

2011

In a couple of my projects I needed to be able to position and scale or rotate based on different anchor points on the same sprite. For example, I am using CCLabelTTF and I’m trying to highlight different parts of a word. So I am scaling or rotating the first letter in the word without ...
