如何整理一个RandomRangeInt只能从Unity的主线程中调用？

Question

My goal here is to make the spawned object have completely random colors. I keep getting the error in the question title and I have no idea what I'm doing, right or wrong.

using UnityEngine;
using System.Collections;

public class EnemySpawningScript : MonoBehaviour 
{
    public GameObject spawnType = null;
    public float ScaleMin = 0.5f;
    public float ScaleMax = 2.0f;
    public Color OriginalColorforSpawned = new Color(Random.Range(1,255), Random.Range(1,255), Random.Range(1, 255));

void Awake ()
{
    OriginalColorforSpawned = spawnType.GetComponent<Renderer>().sharedMaterial.color;
}

void Update ()
{
    if (Input.GetKey (KeyCode.Space)) 
    {
        GameObject BasicUnit = Instantiate(spawnType) as GameObject;
        BasicUnit.transform.position = this.transform.position;
        float ScaleOfEnemies = Random.Range (ScaleMin, ScaleMax);
        BasicUnit.transform.localScale = Vector3.one * ScaleOfEnemies;
        BasicUnit.AddComponent<Rigidbody>();

        BasicUnit.name = "ProtoTypeEnemies";
    }
}
}

Put the color init into Awake or Start . You can't do a Random.Range in the declaration line.

Also, you try to set it when you declare it, but in your Awake you override it directly.

Edit:
It should look like this:

public GameObject spawnType = null;
public float ScaleMin = 0.5f;
public float ScaleMax = 2.0f;
public Color OriginalColorforSpawned;

void Awake ()
{
    OriginalColorforSpawned = new Color(Random.Range(0.0f, 1.0f), Random.Range(0.0f, 1.0f), Random.Range(0.0f, 1.0f));

    spawnType.GetComponent<Renderer>().material.color = OriginalColorforSpawned;
}

Edit:
Color takes values from 0.0f to 1.0f.

Also, the recommended naming for variables is lowerCamelCase (eg originalColorForSpawned ).

Edit:
Now only effecting the newly spawned object:

using UnityEngine;
using System.Collections;

public class EnemySpawningScript : MonoBehaviour 
{
    public GameObject spawnType = null;
    public float scaleMin = 0.5f;
    public float scaleMax = 2.0f;

    void Update ()
    {
        if (Input.GetKey (KeyCode.Space)) 
        {
            GameObject basicUnit = Instantiate(spawnType) as GameObject;
            basicUnit.transform.position = transform.position;
            float scaleOfEnemies = Random.Range (scaleMin, scaleMax);
            basicUnit.transform.localScale = Vector3.one * scaleOfEnemies;

            // the rigidbody should just be added to the prefab directly
            basicUnit.AddComponent<Rigidbody>();

            basicUnit.name = "ProtoTypeEnemies";

            // change color of this enemy
            Color rColor = new Color(Random.Range(0.0f, 1.0f), Random.Range(0.0f, 1.0f), Random.Range(0.0f, 1.0f));
            basicUnit.GetComponent<Renderer>().material.color = rColor;
        }
    }
}
