Singletons

Original post by David Laskey on UnityPatterns

public class MusicManager : MonoBehaviour
{
//We make a static variable to our MusicManager instance
public static MusicManager instance { get; private set; }
//When the object awakens, we assign the static variable

{
instance = this;

Convert an array of floats to an array of Vector3. (Also serialize a vector 3 array to string, just for fun)

##Converting an array of floats to string

using System.Collections.Generic;

//...

	Vector3[] ConvertToVector3Array (float[] floats)
	{
 List vector3List = new List();

How to force update the RealSense R200 firmware

tl;dr : run FWUpdateR200.exe with the -force flag

I use this to fix the faulty R200 when it doesn't show up in Unity3D. Force updating the firware helps.

Start installing the SDK/DCM

Search for FWUpdateR200.exe

It was found in C:\Windows.old\Users\%User%\AppData\Local\Temp\%SomeGibberishID%\plugins\FWUpdateR200\Bin
