While developing a game, I wanted to enable the autonomous characters to see where they’re going – that is, to tell them what they’re about to stumble into, without using colliders. The answer was to cast a Ray, angled slightly downward, in front of the character, so it can see if it’s about to walk into a tree, or off a cliff, before it happens.

Unity – Animation Blend Trees
How to create infinitely varied animation with your Unity characters.
A very powerful feature in the Unity Editor is the Blend Tree. This is an extension to an Animation Controller, which allows you to ‘blend’ the joint movements of multiple animations and control the ratio of blending with one or more parameters.
Unity – automatically choosing key or accelerometer input
I knocked up a quick demo to show how you might create a Unity game, which uses either keyboard input, or the accelerometer of a mobile device, without having to change any code, include any third party libraries, or use conditional compilation.

SmoothBitmap – How to ensure Bitmap pixel smoothing in AS3
A common oversight in Flash projects, when using a Bitmap with loaded content is that Flash will revert a Bitmap’s smoothing parameter to false when you replace its bitmapData. That is, when the data loads into the Bitmap, anti-aliasing will get turned off. This is simple enough to fix, but since you may not know if someone is going to replace the bitmapData of a Bitmap you have created – then it’s much better to code defensively for it.
This little SmoothBitmap class is for just such an occasion. Instantiate it like a regular Bitmap and, no matter what another developer does with it, smooth, anti aliased pixels when scaling/rotating will be ensured. Enjoy 🙂
