在Unity中旋转2D世界

Question

I am looking at developing a game within Unity by using C# The game will take the gyroscope orientation and rotate accordingly to the direction of which the phone is rotated.

I am curious of how this would work, I understand how I would be able to read and update the gyroscope orientation however I am unsure on how to assign this to a world to rotate. There will be a player on world which will be the next challenge to prevent the player clipping through the world when it is rotated. Hence the world should rotate around the players current location.

I currently have no code as I am in the process of designing this, however i am unable to get the logic of how to make this work within my head

Thankyou

如果我的目标正确，我猜想像在“拳头游戏”中那样旋转摄像机就足够了，并且比在保持玩家静止的情况下旋转整个世界要简单得多。

This is how I would go about it, first I wouldn't rotate the world, as that is alot of objects to rotate, but if you really wanted to you could parent all of the world to a single game object, then rotate that object about an axis based off of the players position(See this: https://docs.unity3d.com/ScriptReference/Transform.RotateAround.html ).

The simplest way is to attach your main camera to your player(Drag and drop it on your Player Object in your hierchy), then rotate your player.

for an example you can test on your machine without the gyroscrope:

using UnityEngine;

public class rotatorScript: MonoBehaviour {
    void Update() {
        // Will Rotate based off of left/right arrows
        float rotator = -Input.GetAxisRaw("Horizontal");
        // Move up or down based off of up/down Arrows
        float verticalDirection = Input.GetAxisRaw("Vertical");
        // Do the actual movement... using space.self so it is based on the player not the world.
        transform.Translate(Vector3.up * verticalDirection * Time.deltaTime * 5f, Space.self);
        transform.Rotate(0f,0f,90f * Time.deltaTime * rotator); 
    }
}

This script would be attached to the player.
