I want my random.range script choose between 1 or 2 position not 1 to 2 positions, how to do it? Can i do it with Random.Range?

Here’s my script, it’s working but not the way i want.

using UnityEngine;
using System.Collections;
public class ObstacleSpawnScript : MonoBehaviour {
    public GameObject Car1;
    public Vector3 spawnLocation;
    // Use this for initialization
    void Start () {
        StartCoroutine (ObstacleSpawn ());
    }
    IEnumerator ObstacleSpawn(){
        while (true) {
            spawnLocation = new Vector3(10, -0.5f, Random.Range(-1.55f, 1.55f));
            Instantiate(Car1, spawnLocation, Quaternion.identity);
            yield return new WaitForSeconds(4f);
        }
    }
}

(Random.value > 0.5f ? -1.55f : 1.55f)

Not directly, “range” has a pretty specific meaning, but you can use the same percentage-chance concept used in most loot systems with a simple if-statement. For instance, just do Random.Range from between 0 and 100, and then if the number if less than 50, set a variable to -1.55f, and if it’s over, then set it to 1.55f. Using the same setup, you can make the chances lopsided by doing, for instance, 1-30 (30% chance) and 31-100 (70% chance).

Make an array of potential positions, Randomly select one from the array.

If you pass integers to the random function, you are getting an integer as result. If you use an array, you random call might look something like that:

Random.Range (0, theNameOfYourArray.Length);
