Change property of certain gameobjects without looping through them

Questions & Answers

Hi,
I am wondering if there is a function built into Unity that lets you change properties of certain GameObjects without looping through them. Let’s say I have a simple script called “HasSpeed” with just the property speed.

public class HasSpeed : MonoBehaviour
{
    public float Speed = 1.0f;
}

In a different script I want to change “Speed” without looping through all of the GameObjects. Here is what I don’t want (There are many different ways to get the objects but in essence I would have to loop through them):

public class ChangeAllObjectsWithSpeed : MonoBehaviour
{
    void Update()
    {
        if(Input.GetKeyDown(KeyCode.W))
        {
            HasSpeed[] speedScripts = (HasSpeed[]) GameObject.FindObjectsOfType (typeof(HasSpeed));
            foreach(var current in speedScripts)
            {
                current.Speed = 0.5f;
            }
        }
    }
}

I just want to know if there is a Unity built-in way to handle those kind of things. Is there something which I can use to achieve what I want?

No there is no such a thing, but if you want all the HasSpeed objects to have the same speed you could simply do

     void Update()
     {
         if(Input.GetKeyDown(KeyCode.W))
         {       
             HasSpeed.Speed = 0.5f;
         }
     }

and

public class HasSpeed : MonoBehaviour
 {
     public static float Speed = 1.0f;
 }

but this will make all the scripts share the same speed
