unity camera 起始位置

Question

你好，所以我为我正在制作的 RTS 游戏创建了一个摄像头，但在开始时，摄像头位于 minHight 位置，我无法弄清楚如何更改它希望有人帮助代码有点混乱，它只是为了这里的测试是我希望它从给定的 maxHight 位置而不是 minHight 开始的代码。

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class RtsCamera : MonoBehaviour {


    public float zoomSensitivy = 15;
    private Transform m_Transform;
    public float screenEdgeBorder = 25f;
    public bool useScreenEdgeInput = true;
    public float screenEdgeMovementSpeed = 3f;

    // zoom stuff
    public float heightDampening = 5f;
    public float scrollWheelZoomingSensitivity = 25f;
    public float maxHeight = 10f; //maximal height
    public float minHeight = 15f; //minimnal height
    public LayerMask groundMask = -1;
    public bool autoHeight = true;
    public bool limitMap = true;
    public float limitX = 50f; //x limit of map
    public float limitZ = 50f; //z limit of map
    private float zoomPos = 0; //value in range (0, 1) used as t in Matf.Lerp
    public bool useScrollwheelZooming = true;

    Vector3 tempPos;


    public string zoomingAxis = "Mouse ScrollWheel";

    private float ScrollWheel
    {
        get { return Input.GetAxis(zoomingAxis); }
    }

    private Vector2 MouseAxis
    {
        get { return new Vector2(Input.GetAxis("Mouse X"), Input.GetAxis("Mouse Y")); }

            m_Transform.position.y,

    }

    private void HeightCalculation()
    {
        float distanceToGround = DistanceToGround();
        if (useScrollwheelZooming)
            zoomPos += ScrollWheel * Time.deltaTime * scrollWheelZoomingSensitivity;


        zoomPos = Mathf.Clamp01(zoomPos);

        float targetHeight = Mathf.Lerp(minHeight, maxHeight, zoomPos);
        float difference = 0;

        if (distanceToGround != targetHeight)
            difference = targetHeight - distanceToGround;

       m_Transform.position = Vector3.Lerp(m_Transform.position,
            new Vector3(m_Transform.position.x, targetHeight + difference, m_Transform.position.z), Time.deltaTime * heightDampening);
    }
    private float DistanceToGround()
    {
        Ray ray = new Ray(m_Transform.position, Vector3.down);
        RaycastHit hit;

            return (hit.point - m_Transform.position).magnitude;

        return 0f;
    }

将第 25 行的变量 zoomPos 的值设置为 1 或 0，具体取决于您希望它处于最小高度还是最大高度，您可以在 Start() 或仅在声明中执行此操作变量。

这是因为在HeightCalculation 函数中，它根据zoomPos 的值将高度设置为介于最小值和最大值之间的某个位置，当您使用滚轮时，该值会发生变化，缩放也会发生变化。在运行游戏之前更改zoomPos 可以有效地设置默认起始高度。
