Changing "right" in Vector3.right to a variable

Question

Im trying to change the "right" in transform.position += Vector3.right speed Time.deltaTime; to my variable: direction. My variable: private string direction = "right";

So when i change it, it looks like this: transform.position += Vector3.direction speed Time.deltaTime;

Because then i can change the direction string to either right,left, up or down.

But of course it doesn't work, so how do i implement my variable direction to the vector3, like i did above?

I don't understand why you try to do this way while having a private Vector3 direction would be muuuch simpler....

Anyway... Try the following code which involves reflection

 // At the top of your script
 using System.Reflection;

 // ....

 PropertyInfo propertyInfo = typeof(Vector3).GetProperty(direction, BindingFlags.Public | BindingFlags.Static); 
 
 // Use the PropertyInfo to retrieve the value from the type by not passing in an instance
 Vector3 vector = (Vector3) propertyInfo.GetValue(null, null);

 transform.position += vector * speed * Time.deltaTime;
