Question

统一制作游戏，我正在使用此代码。我不知道出了什么问题，为什么精灵在实例化时不会改变颜色。你能帮帮忙，所以我不会失去理智吗？：D（我也会随机生成GameObjects）

int randomIndex = UnityEngine.Random.Range(0, arrows.Length);
    GameObject prefab = arrows[randomIndex];
    GameObject clone = Instantiate(prefab, new Vector3(0.02F, 2.18F, -1), Quaternion.identity);

    //change colors
    colors[0] = new Color (250, 250, 250);
    colors[1] = new Color (144, 249, 242);
    colors[2] = new Color (20, 173, 163);
    colors[3] = new Color (21, 129, 168);
    colors[4] = new Color (5, 95, 127);
    colors[5] = new Color (58, 125, 196);
    int colorRandomIndex = UnityEngine.Random.Range(0, colors.Length);
    SpriteRenderer renderer = clone.GetComponent<SpriteRenderer>();
    renderer.color = colors[colorRandomIndex]; 
    myObjects.Add(clone);

Answer 1

也许试试renderer.material.color = colors[colorRandomIndex];？自从我使用Unity以来已经有一段时间......

Answer 2

你能尝试使用

吗？

好的，错误就是你创建颜色的方式，Color只接受0到1之间的浮点值。你需要使用Color32

int colorRandomIndex = UnityEngine.Random.Range(0, colors.Length);

clone.GetComponent<SpriteRenderer>().material.color = colors[colorRandomIndex];

不要忘记也将数组更改为colors[0] = new Color32 (250, 250, 250, 255); colors[1] = new Color32 (144, 249, 242, 255); colors[2] = new Color32 (20, 173, 163, 255); colors[3] = new Color32 (21, 129, 168, 255); colors[4] = new Color32 (5, 95, 127, 255); colors[5] = new Color32 (58, 125, 196, 255);

GameObject数组的随机颜色
