Hi there,
I want to set a negative value in an enumeration, but it seams not to be possible, i would like to set -1 for left as so:

enum face
    {
    LEFT    = -1, // error: no negatives values
    RIGHT    = 1,
    }


public function Start() : void {
   
   facing = face.DROITE;

do you now a way to make it work? is there a way to set up CONSTANTS?
thank you.

Actually you cannot use negative value with Javascript.

You can in C# though as enum are int internally. But Js does not allow.

You can use the offset trick.

In short, figure out the largest possible negative value. Let’s say it’s -100.

Make each value of the enum 100 higher.

Create a function to get the enum’s value. In the function, subtract 100 from the enum’s actual value.
