What exactly does this operator |= do? I have this code for Unity in C# 

bool shoot = Input.GetButtonDown("Fire1");
shoot |= Input.GetButtonDown("Fire2");

    `a |= b` is equal to `a = a | b`. Read from : [`|=` Operator (C# Reference)](https://msdn.microsoft.com/en-us/library/h5f1zzaw.aspx) Next time, please use google first. – Soner Gönül Jan 29 '15 at 11:03

    I find that question valid. It's rather difficult to search for "|=" even with a combination of keywords (C#, operator) on Google and finding a good answer for the question. – CodeSmile Jan 29 '15 at 11:07

    A C# developer should have a [list of operators](https://msdn.microsoft.com/en-us/library/6a71f45d.aspx) handy. @LearnCocos2D: For that same reason this question will have little future value. – H H Jan 29 '15 at 11:11

    Where do we even begin to justify what a programmer "should have" or "should know"? – CodeSmile Jan 29 '15 at 11:18
