Can someone explain...

Hello
I tried to do this using a public variable but for some reasons if I use the variable the values are not updating.
Also I tried to pass values into Rect from variables but I get an error.

public class MainMenuGUI : MonoBehaviour 
{
    //Buttons Variables
    public float btnWidth = Screen.width / (float)1.66;
    public float btnHeight = Screen.width / 7;
    public float heightPos = 150;

    public Rect buttonRect = new Rect(Screen.width / 2 - (Screen.width / (float)1.66) / 2 + 50, Screen.height / 2 - 25, btnWidth , btnHeight);

    void OnGUI()
    {
        if (GUI.Button(new Rect(Screen.width / 2 - (Screen.width / (float)1.66) / 2, Screen.height / 2 - (Screen.width / 7) - 100, Screen.width / (float)1.66, Screen.width / 7), "Play"))
        {
            print("You clicked the button!");
        }
    }
}

The errors I get when I pass variables into new Rect instead of the actual value.

Try declaring them where they are and assigning values in the Start() function.

No problems!

Yeah, Can’t use one variable in the declaration of another, outside of a function.

Oh yeah, it makes sense now that you say.
