Error with using velocity speed from another script

Vector2 velocity = new Vector2(0, RightTree.speed)

I have a script to make tress move in background for 2d driving game, but with the line of code above I’m left with “Error CS0120: An object reference is required for the non-static field, method, or property ‘RightTree.speed’ (CS0120) (Assembly-CSharp)”. I would just have it as 4 or something but it’s constantly changing and I know I could copy and paste or rewrite same code over into this script but I want to know of a way too do it like this.

What you first need to do is to set the original Vector 2 as public static variable just like this.

Example:

using UnityEngine;
using System.Collections;

public class originalScript : MonoBehaviour {

	public static Vector2 originalVector2; //Here you'll set it as publuc static so you can call it from any other script.

	void Start () {
		originalVector2 = new Vector2(0,0); //Or whatever your values are.
	}
}

Then you can call it on any other script you want. Justt like this.

using UnityEngine;
using System.Collections;

public class staticCall : MonoBehaviour {

	Vector2 newVel; //Variable reference in the new script.

	void Update () {
		newVel = originalScript.originalVector2; //Example of calling the original variable from the original script. First call the original script's name, then the name of the variable followed by a dot.
	}
}

Just change the names and values of this example and it should work. Good luck. :wink:
