I recently stumbled upon an old bit of code which demonstrates a technique I created for an efficient scrolling data grid on the YouView TV platform. I call it ‘Blit Scrolling’. Below is a demo of the concept (click on the window and use the arrow keys to scroll around):

Mobile devices are becoming more and more powerful. However, not all your users will have high-end mobile devices, so you should keep a low-powered device handy for testing the performance of your games.
If you follow the usual advice for mobile devices (use low-poly models, minimal lights, few effects and static objects where possible) you’ll be OK on most devices, but you may be caught out on some devices – resulting in annoyed users. Here are a few tricks to try if you still need to improve the performance of your Unity game. Continue reading Boosting Unity performance on mobile devices
If you want to write a unit test which verifies that something implements a particular interface, or extends a particular class, here’s how…

One of the most problematic constraints when developing applications for mobile or Set Top Box is video memory (AKA VRAM). You often will not have control over how much video memory is allocated to your application, or what the fallback behaviour is when your application uses too much. Continue reading Sneaky tricks for developing on small devices – Bitmap ‘folding’
YouView is a Smart TV service in the UK, which runs on Set Top Boxes and certain Smart TVs. I worked on the core UI for years and thought I’d share some insights into best practices when building applications for such resource constrained devices.

It gets scary out there sometimes. During my freelance career I’ve worked at a lot of different companies and have seen such coding horrors as you cannot imagine. So I thought I’d start immortalising some of them – so that we can all learn better coding practices, by looking at the bad.
Starter for 10 – What’s wrong with this picture?
public function doSomething(stuff:String):void
var newPixels:BitmapData = new BitmapData(someUint, someUint, true, 0);
someBitmap.bitmapData = newPixels;
Did you spot the fubar? It’s not an obvious one. Continue reading CODING WRONGS – Where do I start with the bad?
