Is there a VAR in C#?

The C# var keyword is used to declare implicit type variables in C#.

Is VAR faster C#?

Can I use VAR in Java?

In Java, var can be used only where type inference is desired; it cannot be used where a type is declared explicitly. If val were added, it too could be used only where type inference is used. The use of var or val in Java could not be used to control immutability if the type were declared explicitly.

Is it possible to type Var in Unity?

Edit: Ah, beaten to it. harmless, Unity currently only supports C# 2.0, so you’ll have to use strong typing. dreamora, that’s not strictly true. var is very much available in C# 3.0. Which is all the more reason for Unity to upgrade Mono to the latest version… other than that you should be fine.

They contain 3rd order SH to be evaluated by world space normal (see ShadeSH9 from UnityCG.cginc ). The variables are all half4 type, unity_SHAr and similar names. Up to 8 lights are set up for a Vertex pass type; always sorted starting from the brightest one.

Why unity doesn’t support scoped var declaration?
