Question by Essential · Feb 02, 2012 at 11:17 AM · variableoperator

How is this operator in a variable declaration?

Have noticed this line in one of the bundled Unity scripts. Am not familiar with the use of comparison operators when setting a variable. Can anyone explain what it means?

 movement.isMoving = Mathf.Abs (inputDirection) > 0.1;

movement.isMoving is a boolean variable, You are checking whether the value of input direction is more than 0.1 either in negative or positive...

basically Mathf.Abs(inputDirection)>0.1 is a condition so it will return either true or false to the variable isMoving. This is equal to

 if(Mathf.Abs (inputDirection) > 0.1)
 {
          movement.isMoving=true;
 }
 else
 {
          movement.isMoving=false;
 }


Aditional: Check ternary operator is more like a simple if else loop that could also be used during variable declaration, with a condition. eg: var x=(y<3?3:3); this will clamp the value to 3 if the value is 3 or more or you will get the value of y in x. Hope it is clear :)

Thanks for this answer, @flamy, I was curious too about this. Just a question: is it possible both in Unityscript and C#?

I ask because I've never seen this synthax.

yes it is in any language. it is not specific to unityscript or c#....

but prefer not to use it though, because it would make the code hard to read sometimes.
