TI-89 Multiple Variables on One Line

Clever preprocessor macro in HLSL

Element-wise Vector Multiplication in Unity (Vector3.Scale)

I often need to multiply two vectors together one element at a time. This is called the Hadamard Product [https://en.wikipedia.org/wiki/Hadamard_product_(matrices)]. Typically I do it this way: Vector3 a=new Vector3(1,2,3); Vector3 b=new Vector3(4,5,6); Vector3 result = new

The top 5 things I've learned as an Indie Unity Developer

I have released one game implemented with the Unity engine and have two more in the pipeline. Over time I've learned quite a bit, often by doing things the wrong way first. 1. Embrace component-based design and avoid Inheritance When I first started working with Unity I was coming from
