您可以使用Unity的`SystemInfo.batteryLevel`属性获取设备当前的电量百分比。但是需要注意的是,该属性只在Android和iOS平台上可用,其他平台上该属性的值始终为1。在Android平台上,您可以使用以下代码来获取设备的电量:
```csharp
if (Application.platform == RuntimePlatform.Android)
{
using (AndroidJavaClass unityPlayerClass = new AndroidJavaClass("com.unity3d.player.UnityPlayer"))
{
AndroidJavaObject unityActivity = unityPlayerClass.GetStatic<AndroidJavaObject>("currentActivity");
AndroidJavaObject intentFilter = new AndroidJavaObject("android.content.IntentFilter", new object[] { "android.intent.action.BATTERY_CHANGED" });
AndroidJavaObject batteryIntent = unityActivity.Call<AndroidJavaObject>("registerReceiver", new object[] { null, intentFilter });
int level = batteryIntent.Call<int>("getIntExtra", new object[] { "level", 0 });
int scale = batteryIntent.Call<int>("getIntExtra", new object[] { "scale", 100 });
float batteryLevel = (float)level / (float)scale;
Debug.Log("Battery level: " + batteryLevel);
}
}
```
这段代码会获取当前的Activity,并注册一个`android.intent.action.BATTERY_CHANGED`广播接收器,然后从接收到的广播中获取电量和电池容量信息,最后计算出当前的电量百分比并打印出来。
