android - Unity 2D游戏中的屏幕裁剪问题

Question

我用 unity 开发了一款 2-D 游戏。首先，我在网络播放器上运行游戏，我的屏幕从两端切开。现在我正在从中创建 android apk。然后在安卓设备上它也从两端切割。我们正在使用自由纵横比。我不太了解屏幕尺寸。那么如何克服这个问题呢？

CameraFollow.cs 脚本-

using UnityEngine;
using System.Collections;

public class CameraFollow : MonoBehaviour 
{
    public float xMargin = 1f;      // Distance in the x axis the player can move before the camera follows.
    public float yMargin = 1f;      // Distance in the y axis the player can move before the camera follows.
    public float xSmooth = 8f;      // How smoothly the camera catches up with it's target movement in the x axis.
    public float ySmooth = 8f;      // How smoothly the camera catches up with it's target movement in the y axis.
    public Vector2 maxXAndY;        // The maximum x and y coordinates the camera can have.
    public Vector2 minXAndY;        // The minimum x and y coordinates the camera can have.


    private Transform player;       // Reference to the player's transform.


    void Awake ()
    {
        // Setting up the reference.
        player = GameObject.FindGameObjectWithTag("Player").transform;
        //camera.orthographicSize = 640 / screenwidth * screenheight / 2;
    }


    bool CheckXMargin()
    {
        // Returns true if the distance between the camera and the player in the x axis is greater than the x margin.
        return Mathf.Abs(transform.position.x - player.position.x) > xMargin;
    }


    bool CheckYMargin()
    {
        // Returns true if the distance between the camera and the player in the y axis is greater than the y margin.
        return Mathf.Abs(transform.position.y - player.position.y) > yMargin;
    }


    void FixedUpdate ()
    {
        TrackPlayer();
    }


    void TrackPlayer ()
    {
        // By default the target x and y coordinates of the camera are it's current x and y coordinates.
        float targetX = transform.position.x;
        float targetY = transform.position.y;

        // If the player has moved beyond the x margin...
        if(CheckXMargin())
            // ... the target x coordinate should be a Lerp between the camera's current x position and the player's current x position.
            targetX = Mathf.Lerp(transform.position.x, player.position.x, xSmooth * Time.deltaTime);

        // If the player has moved beyond the y margin...
        if(CheckYMargin())
            // ... the target y coordinate should be a Lerp between the camera's current y position and the player's current y position.
            targetY = Mathf.Lerp(transform.position.y, player.position.y, ySmooth * Time.deltaTime);

        // The target x and y coordinates should not be larger than the maximum or smaller than the minimum.
        targetX = Mathf.Clamp(targetX, minXAndY.x, maxXAndY.x);
        targetY = Mathf.Clamp(targetY, minXAndY.y, maxXAndY.y);

        // Set the camera's position to the target position with the same z component.
        transform.position = new Vector3(targetX, targetY, transform.position.z);
    }
}

由于您正在制作 2D 游戏，我假设您使用的是正交相机。与透视相机不同，正交相机在屏幕上显示的内容越多，分辨率越大。

您需要规范化 orthogonal size想要的解决方案:

 camera.orthographicSize = 640/screenwidth * screenheight/2

在上面的代码中，正交大小被归一化为 640 像素宽度。 ( Link )
