[英]Get level index by using scene name in Unity
I know that there is a way to get level name by index: 我知道有一种通过索引获取级别名称的方法:
string levelName = Application.GetLevelNameByIndex(2);
But is there a way to identify the level index of a scene using its name? 但是,有没有一种方法可以使用其名称来标识场景的级别索引?
Looks like that's not very well supported right now, see this answer . 看起来目前还没有很好的支持,请参见此答案 。
Only in editor - as per this question.
仅在编辑器中-根据此问题。
Vote for it here, it's a bizarrely absent feature.
在这里投票,这是一个奇怪的缺席功能。
Note that if you want to show text to the user, you probably want a long name, a description, and a screenshot anyway.
请注意,如果要向用户显示文本,则可能始终需要长名称,描述和屏幕截图。
EDIT: Found an answer that has an editor script that may be of assistance. 编辑: 找到了一个可能具有帮助的编辑器脚本的答案。
Here is a method you could use, assuming you know how many scenes are in your game. 假设您知道游戏中有多少个场景,可以使用以下方法。
using UnityEngine;
using System.Collections;
public class SceneDetector : MonoBehaviour {
public int numberOfScenes = 5;
public String[] sceneNames;
void Start() {
sceneNames = new String[numberOfScenes];
for(int i = 0; i < numberOfScenes; i++)
{
sceneNames[i] = Application.GetLevelNameByIndex(i);
}
}
public int GetSceneIndex(String sceneName)
{
for(int i = 0; i < sceneNames.length; i++)
{
if(sceneName == sceneNames[i])
{
return i;
}
}
return -1;
}
}
And of course as you can see if you run GetSceneIndex
and it returns -1, then the string you passed in is not a name of a scene. 当然,如您所见,如果您运行
GetSceneIndex
并返回-1,则您传入的字符串不是场景名称。
