Question by PigInATuxedo · Dec 18, 2014 at 01:18 AM · variablebooleandatabooleans

Unity says there is no such thing as a boolean.

Here is the line of code in question, it says there is an error.

 boolean isGrounded = true;

If you're using JS it's

 var isGrounded : boolean = true;

If it's CS:

 bool isGrounded = true;

So as usual Unity is right. There is no such thing as a Boolean as you have described it.

bool is the keyword most languages use, the same way Integer is almost always int.

Actually there is, but nobody would use the underlying type name. $$anonymous$$ost .NET languages have alias names for those primitive types. Like:

 string = System.String
 bool   = System.Boolean
 int    = System.Int32
 object = System.Object
 //enum   = System.Enum // not a real alias since it's actually a keyword.

In UnityScript the alias for System.String is String

See this list for more details.

I'm so going to use System.Int32 somewhere. I guess it makes sense, now I see it. But I'd never thought that the primitives actually had to have definitions somewhere too.
