我制作了一个相机脚本，跟随玩家使用lerp使其看起来更平滑，但由于某种原因，它在某些突然区域行走时看起来很滞后。
玩家行走的地面是瓷砖，起初，我认为是微小的细胞间隙造成了问题，但即使我把地面改成了一个实心块，这种情况仍然会发生。所以我得出结论，一定是相机脚本造成了这个问题。
以下是我正在谈论的内容的视频剪辑：https://youtu.be/mmBMHWuHpxo
我认为问题源于我的相机脚本的这一部分：
void SetTargetPos()
{
// By default the target x and y coordinates of the camera are it's current x and y coordinates.
targetX = transform.position.x;
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, transformPlayer.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, transformPlayer.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, currentMinBounds.x, currentMaxBounds.x);
targetY = Mathf.Clamp(targetY, currentMinBounds.y, currentMaxBounds.y);
// Set the camera's position to the target position with the same z component.
transform.position = new Vector3(targetX, targetY, transform.position.z);
TestOutOfCamBounds();
}
顺便说一句，我在不同的Unity项目上有完全相同的脚本，具有相同的变量输入。有一个很小的区别，第二个项目中的所有东西的总体尺寸都比第一个小得多。但它在这个项目上运行得很好。我也尝试过Smoothdamp而不是Lerp，但仍然没有成功。以下是另一个项目的视频剪辑：https://youtu.be/baJmKehYfG0
任何帮助都将不胜感激。
如果你想在这里查看整个脚本，它是：
public class Camera_Controller : MonoBehaviour
{
private static Camera_Controller _instance;
public static Camera_Controller instance;
[Header("Put player here")]
public GameObject player;
public Transform transformPlayer;
[Space]
Vector2 currentMinBounds;
Vector2 currentMaxBounds;
public Vector3 targetPos;
[Space]
[Header("Camera Properties")]
public float xMargin = 1f;
public float yMargin = 1f;
public float xSmooth = 8f;
public float ySmooth = 8f;
public Vector3 velocity = Vector3.zero;
private float targetY;
private float targetX;
[Header("Smooth Transition")]
public Vector3 oldPosition;
public Vector3 targetPosition;
public float transitionsTime;
public bool switchingCamera;
private void Awake()
{
if (_instance != null && _instance != this)
{
Destroy(gameObject);
return;
}
else
{
_instance = this;
}
instance = _instance;
}
void Start()
{
targetPos = transform.position;
}
private 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 - transformPlayer.position.x) > xMargin;
}
private 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 - transformPlayer.position.y) > yMargin;
}
void Update()
{
if (!switchingCamera)
{
SetTargetPos();
}
}
public void SetCamBounds(Vector2 minBounds, Vector2 maxBounds) //Called from Game Events Trough WarpController as trigger
{
currentMinBounds = minBounds;
currentMaxBounds = maxBounds;
}
//SetTargetPos() should be causing the problem
void SetTargetPos()
{
// By default the target x and y coordinates of the camera are it's current x and y coordinates.
targetX = transform.position.x;
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, transformPlayer.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, transformPlayer.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, currentMinBounds.x, currentMaxBounds.x);
targetY = Mathf.Clamp(targetY, currentMinBounds.y, currentMaxBounds.y);
// Set the camera's position to the target position with the same z component.
transform.position = new Vector3(targetX, targetY, transform.position.z);
TestOutOfCamBounds();
}
void TestOutOfCamBounds() //Set Camera some boundaries.
{
if (targetPos.x <= currentMinBounds.x)
{
targetPos.x = currentMinBounds.x;
}
if (targetPos.x >= currentMaxBounds.x)
{
targetPos.x = currentMaxBounds.x;
}
if (targetPos.y <= currentMinBounds.y)
{
targetPos.y = currentMinBounds.y;
}
if (targetPos.y >= currentMaxBounds.y)
{
targetPos.y = currentMaxBounds.y;
}
}
}
尝试在Late update中调用cammer运动，示例如下。
private void LateUpdate() {
SetTargetPos();
}
这是在更新方法之后调用的，可能有助于减少cammer抖动。
您的第二个视频是2d，第一个是3d。也试着调整z位置。
targetZ = Mathf.Lerp(transform.position.z, transformPlayer.position.z, zSmooth * Time.deltaTime);
我找到了一个解决方案！我将更新函数更改为LateUpdate((。。。抱歉浪费你的时间
