我是C#/ Unity的新手(温柔) - 我试图创建自己的脚本,向Inspector添加一个公共变量,这样我就可以让一个脚本适用于多个GameObjects(左右)我想)。
脚本非常简单。
它适用于PC,但它在Android上无效。
using UnityEngine;
using UnityEngine.SceneManagement;
using UnityEngine.EventSystems;
public class BtnLoadScene : MonoBehaviour {
public Object SceneObj;
private string SceneName;
public void LoadLevel()
{
SceneName = SceneObj.name;
Debug.Log (SceneName);
SceneManager.LoadScene(SceneName);
}
}
我将此脚本作为组件附加到驱动场景加载的所有按钮(在整个应用程序中)。再次,这里的价值是我可以拖动我的"场景"从资产文件夹到检查员/组件(因此我不必明确管理" ints"或"字符串" - 它将全部通过对象完成参考文献)。
再次,这适用于PC 更新:根据评论中的建议,我在独立播放器中尝试了这个并且它失败了。这仅适用于Unity编辑器。当我为Android构建时(是的它编译并且我可以安装APK)它不起作用 - 第一个场景加载,按钮响应我的触摸,我看到它"压下",但是亚行抛出:

如果我输入一个硬编码值(字符串或场景int),它在Android和PC中都能正常工作。但是,由于某些我无法看到的原因,我在Inspector中引用的Scene对象,当我为Android构建时,似乎没有捕获String名称并将其传递给像我想的那样LoadScene()。
有人可以告诉我做错了什么吗?这是不可能的还是愚蠢的想法?
提前谢谢。
答案 0 :(得分:2)
我担心UnityEngine.SceneAsset
只能在编辑器中使用,并且在任何版本中最终都会为null。
但是,Unity3D只需要BuildSettings
列表中的字符串或索引,因此它很简单:只需在检查器中传递场景名称即可。在整个开发过程中,它将是一个常量,并且如果您更改场景名称将会表现相同,就像您将实际的SceneAsset
对象放在那里一样(在两种情况下都会在重命名时失败)。
