Google Cardboard-更改场景时如何面对相同的面孔? [英] Google Cardboard - how to face the same way when changing scenes?
问题描述
我正在创建一个VR游戏，如果用户看着某个按钮，场景就会改变.
I'm creating a VR game, where if a user looks at a button, a scene will change.
问题是，如果我使用SceneManager加载新场景，则用户面对的方向会重置，从而使其成为新的前进方向.例如，我在用户后面有一个退出按钮.如果他们看着它，将会加载新的场景，但是新的前进"将在它们后面，从而使他们必须完全转过身才能使他们的身体再次向前.
The problem is that if I load a new scene using SceneManager, the direction that the user is facing resets, making it the new forward. For example, I have a quit button located behind the user. If they look at it, a new scene will load, but the new "forward" will be behind them, causing them to have to completely turn around in order for their body to face forward again.
I looked online and came across this post here but this was in Unity 4. It talks about commenting out Recenter() and device.Reset()
我已经重复了Unity 5(我正在使用的版本)中的步骤，但这没有效果.我也无法在Unity 5 Google Cardboard脚本中看到device.Reset()的代码.
I have repeated the steps in Unity 5 (the version I am using) but this has no effect. I cannot see a device.Reset() piece of code in the Unity 5 Google Cardboard scripts either.
在播放模式下从当前场景加载新场景时，如何保持相同的方向?
How can I keep facing the same direction when I load a new scene from a current scene in play mode?
谢谢！
推荐答案
仅在退出时存储所有摄像机"的位置和旋转值.将它们加载到Start函数中.我大约一年前做了类似的事情，并且会分享脚本.只需将其附加到场景中的任何 GameObject .确保将相机放在每个插槽中.移动相机，然后退出场景.下次再次播放时，它应保持所有摄像机的位置.
Simply store the All the Camera's position and rotation values on exit. Load them in the Start function. I did something similar about a year ago and will share the script. Just attach it to any GameObject in the scene. Make sure to put cameras in each slot. Move the camera then exit the scene. It should hold the position of all the cameras next time you play again.
如果停止工作，请调用reset()函数一次以重置保存的数据，然后将其注释掉.仅当它停止工作时才应调用它，这从未发生在我身上.
If it stops working, call the reset() function ONCE to reset the saved data then comment it out. It should only be called when it stops working which never happened to me.
