Question

我有一个2D正射相机，用于与网球类似的游戏。我一直在研究这个代码，我想我到目前为止只是其中的一部分。目前......它......让两个玩家保持一致，框架更加朝向人类玩家 - 玩家一。但是，它也有降低到地面以下的趋势 - 特别是当它缩小以保持目标在视野中时。有四个具体目标：地面，球，一号球员和二号球员。

地面应始终位于底部＆＃39;否则当相机低于地面时，它会显示天空 - 这不是真正理想的效果。这是我迄今为止开发的代码......两个玩家都是有效的桨，但它只显示了它们之间的中心：

using UnityEngine;
using System.Collections;

public class CameraController : MonoBehaviour {

    // Moving Camera, This Camera tries to follow Player One, Two, and Ball //

public static CameraController Instance;
public Transform PlayerOne;
public Transform PlayerTwo;
public Transform Ball;

public bool Ready = false;

private float MinX = -46.0f;
private float MaxX = 46.0f;

private float MinY = 12.0f;
private float MaxY = 35.0f;

private float LimitFromPlayerX = 20.0f;
private float LimitFromPlayery = 20.0f;

private float DistanceToGround = 0.0f;
private float DistanceFromCenter = 2.0f;

private float Height = 4.0f;

private float Damping = 5f;

private Vector3 EstimatedCameraPosition = Vector3.zero;
private Vector3 WantedPosition = Vector3.zero;

void Awake()
{
    Instance = this;

}

public void SetCameraPosition()
{
    Vector3 PlayerPosistion = PlayerOne.position;

    PlayerPosistion.z = -10.10f;

    transform.position = PlayerPosistion;
}

// Update is called once per frame
void FixedUpdate () {
    if (Ready) {
        Vector3 PlayerPosistion = PlayerOne.position;

        PlayerPosistion.z = -10.10f;

        Vector3 CameraPosition = transform.position;

        CameraPosition.z = -10.10f;

        // Get the Distance from the Player to the Ball //
        Vector3 WantedPosition = PlayerTwo.transform.position - -PlayerOne.transform.position;

        float WPMag = Mathf.Abs(WantedPosition.magnitude);

        WPMag = Mathf.Clamp(WPMag, 20, 40);

        Debug.Log(WPMag);

        Camera.main.orthographicSize = WPMag;

        transform.position = Vector3.Lerp(CameraPosition, WantedPosition, Damping * Time.deltaTime);
    }
}

void LateUpdate()
{
    Vector3 Posit = transform.position;
    Posit.x = Mathf.Clamp (Posit.x, MinX, MaxX);
    Posit.y = Mathf.Clamp (Posit.y, MinY, MaxY);

    transform.position = Posit;
}

}

WPMag是我尝试缩小并至少匹配玩家，但到目前为止它只是部分工作。

要将所有三个物体保持在视野中，您需要将相机对焦于中点或平均值＃34;三个物体的位置。获取三个对象的中点就像获取两个对象的中点一样：(PlayerOne.position + PlayerTwo.position + Ball.position) / 3.0f

然后，您希望将正交尺寸设置为距离三个跟踪对象的中点最远的距离。这将确保所有三个对象都保留在框架中。

最后，为了防止相机显示地下天空，您应该对相机的Y位置强制执行下限。正交尺寸是视口垂直高度的一半，因此您可以使用CameraPosition.y = Mathf.Max(CameraPosition.y, groundHeight + camera.main.orthographicSize)

为Unity3D构建一个正交相机，我怎样才能保持四个特定的目标？
