using System.Collections; using System.Collections.Generic; using UnityEngine; public class CameraController : MonoBehaviour { public Transform CameraRotation; private float Mouse_X; private float Mouse_Y; public float MouseSensitivity; public float xRotation; void Update() { Mouse_X = Input.GetAxis("Mouse X") * MouseSensitivity * Time.deltaTime; Mouse_Y = Input.GetAxis("Mouse Y") * MouseSensitivity * Time.deltaTime; xRotation = xRotation - Mouse_Y; xRotation = Mathf.Clamp(xRotation, -80f, 80f); CameraRotation.Rotate(Vector3.up * Mouse_X); this.transform.localRotation = Quaternion.Euler(xRotation, 0, 0); } }如何在这段代码上增加代码

这段代码是一个简单的摄像机控制脚本，它可以让摄像机根据鼠标的移动来旋转视角。如果你想要在这段代码上增加功能，可以根据具体需求来进行扩展。以下是一些可能的扩展功能： 1. 摄像机缩放：你可以通过添加代码...

using System.Collections; using System.Collections.Generic; using UnityEngine; public class CameraController : MonoBehaviour { public Transform CameraRotation; private float Mouse_X; private float Mouse_Y; public float MouseSensitivity; public float xRotation; void Update() { Mouse_X = Input.GetAxis("Mouse X") * MouseSensitivity * Time.deltaTime; Mouse_Y = Input.GetAxis("Mouse Y") * MouseSensitivity * Time.deltaTime; xRotation = xRotation - Mouse_Y; xRotation = Mathf.Clamp(xRotation, -80f, 80f); CameraRotation.Rotate(Vector3.up * Mouse_X); this.transform.localRotation = Quaternion.Euler(xRotation, 0, 0); } }如何在这段代码上增加代码让弹窗出现时，用户无法与背景交互，直到关闭弹窗。

可以使用以下代码实现： csharp void OnGUI() { if (showPopup) { GUI.Window(0, new Rect(0, 0, 200, 200), PopupWindow, "Popup"); Cursor.lockState = CursorLockMode.Locked; } else { Cursor.lock...

请解释 private void Update() { mouseX = Input.GetAxis("Mouse X") * mouseSensitivity * Time.deltaTime; mouseY = Input.GetAxis("Mouse Y") * mouseSensitivity * Time.deltaTime; xRotation -= mouseY; xRotation = Mathf.Clamp (xRotation, -70f, 70f); player.Rotate (Vector3.up * mouseX); transform.localRotation = Quaternion.Euler(xRotation, 0, 0); }

这段代码通常用于实现第一人称视角的相机旋转。具体来说，它通过获取鼠标在水平和垂直方向上的移动量，来控制相机的旋转。主要包括以下几个步骤： 1. 获取鼠标在水平和垂直方向上的移动量 csharp mouseX = ...

判断右键是否按下 if （Input.GetMouseButton（1）） { 获取鼠标在水平和垂直方向上的移动距离 float mouseX = Input.GetAxis（“Mouse X”）; float mouseY = Input.GetAxis（“Mouse Y”）; currentRotationY += mouseX * rotationSpeed; currentRotationX -= mouseY * rotationSpeed; float targetRotationY = currentRotationY + mouseX * rotationSpeed; float targetRotationX = currentRotationX - mouseY * rotationSpeed; // 限制上下旋转的角度 currentRotationX = Mathf.Clamp(currentRotationX, minYAngle, maxYAngle); // 使用平滑插值逐渐改变当前旋转角度到目标旋转角度 currentRotationY = Mathf.Lerp(currentRotationY, targetRotationY, rotationSmoothness * Time.deltaTime); currentRotationX = Mathf.Lerp(currentRotationX, targetRotationX, rotationSmoothness * Time.deltaTime); float targetDistance = Mathf.Lerp(0.5f, distance, (currentRotationX - minYAngle) / (maxYAngle - minYAngle)); float newDistance = Mathf.Lerp(distance, targetDistance, rotationSmoothness * Time.deltaTime); transform.position = target.position - transform.forward * newDistance; // 设置摄像机的旋转 Quaternion yRotation = Quaternion.Euler(0, currentRotationY, 0); Quaternion xRotation = Quaternion.Euler(currentRotationX, 0, 0); Quaternion rotation = initialRotation * yRotation * xRotation; transform.rotation = rotation; }Vector3 direction =this.transform.position- target.position; Vector3 negDistance = new Vector3(0.0f, 0.0f, -distance); Vector3 position = transform.rotation * negDistance + target.position; //Vector3 vertexPosition = target.position + target.up * distance; // // 从玩家的位置沿着朝向摄像机发出射线 Ray ray = new Ray(target.position, direction.normalized); if (Physics.Raycast(ray, out hit,distance)) { //Debug.DrawRay(target.position, vertexPosition, Color.red); if (hit.collider.gameObject != target.gameObject) { transform.position = transform.rotation* new Vector3(0.0f, 0.0f, -Vector3.Distance(hit.point, target.position)) + target.position; //transform.position=hit.point; } else { //transform.position = position; } } else { transform.position = position; }这段代码摄像机会一会正常位置,一会到玩家身上,怎么修改

根据你提供的代码，我看到你在鼠标右键按下时进行了一系列操作来控制摄像机的旋转和位置。根据你的描述，你希望摄像机在玩家身上时保持固定的位置，而不是跟随玩家移动。在你的代码中，当射线检测到与玩家对象不同...

targetValue = operation.progress; if (operation.progress >= 0.9f) { targetValue = 1.0f; } if (targetValue != loadingSlider.value) { loadingSlider.value = Mathf.Lerp(loadingSlider.value, targetValue, Time.deltaTime * SliderLoadSpeed); if (Mathf.Abs(loadingSlider.value - targetValue) < 0.01f) { loadingSlider.value = targetValue; } } loadingText.text = ((int)(loadingSlider.value * 100)).ToString() + "%"; if ((int)(loadingSlider.value * 100) == 100) { operation.allowSceneActivation = true; }

这段代码是一个用于实现游戏场景加载进度条的脚本。具体来说，它实现了以下功能： 1. 获取场景加载的进度值，并将其赋值给变量targetValue。 2. 如果进度值大于等于0.9，则将targetValue设为1，以确保进度条能够...

public class PlayerMoveOnSphere : MonoBehaviour { public SphereCollider Sphere; public float speed = 5; public bool rotatePlayer = true; public float rotationDamping = 0.5f; // Update is called once per frame void Update() { Vector3 input = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical")); if (input.magnitude > 0) { input = Camera.main.transform.rotation * input; if (input.magnitude > 0.001f) { transform.position += input * (speed * Time.deltaTime); if (rotatePlayer) { float t = Cinemachine.Utility.Damper.Damp(1, rotationDamping, Time.deltaTime); Quaternion newRotation = Quaternion.LookRotation(input.normalized, transform.up); transform.rotation = Quaternion.Slerp(transform.rotation, newRotation, t); } } } // Stick to sphere surface if (Sphere != null) { var up = transform.position - Sphere.transform.position; up = up.normalized; var fwd = transform.forward.ProjectOntoPlane(up); transform.position = Sphere.transform.position + up * (Sphere.radius + transform.localScale.y / 2); transform.rotation = Quaternion.LookRotation(fwd, up); } } }

这是一个在球体表面上移动的脚本，它使用了输入轴的值来更新球员的位置和朝向。如果 rotatePlayer 变量为 true，则还会旋转球员的朝向。同时，它还包括一个 Stick to sphere surface 的功能，确保球员始终停留在球体...

public class Blogs : MonoBehaviour { private bool isMoving = false; private Vector2 moveDirection; private float moveDistance; public float speed; float timeTemp; public Vector2 clickPosition; public Transform targetPoint; public Vector3 localPosition; // Start is called before the first frame update void Start() { moveDirection = clickPosition - (Vector2)transform.position; moveDistance = moveDirection.magnitude; moveDirection.Normalize(); isMoving = true; Destroy(gameObject, 0.3f); } // 子弹方向 void Update() { if (isMoving) { transform.position += (Vector3)moveDirection * speed * Time.deltaTime; moveDistance -= speed * Time.deltaTime; if (moveDistance <= 0f) { isMoving = false; Destroy(gameObject); } } } }优化不和特定物品发生碰撞

public class FirePoint : MonoBehaviour { public Joystick joystick_right; public bool joystick_right_down; public Vector3 shootdirection; public float rotationSpeed = 10f; void Start() { joystick_right_down = false; } // Update is called once per frame void Update() { //右摇杆控制射击 if (joystick_right.Direction.x != 0 || joystick_right.Direction.y != 0) { //让firePoint的方向与摇杆方向一致 // 计算摇杆的方向 Vector2 shootDirection = new Vector3(joystick_right.Direction.x,0, joystick_right.Direction.y); Quaternion targetRotation = Quaternion.LookRotation(shootDirection); transform.rotation = Quaternion.Slerp(transform.rotation, targetRotation, rotationSpeed * Time.deltaTime); joystick_right_down = true; } if (joystick_right.Direction.x == 0 && joystick_right.Direction.y == 0) { transform.rotation = Quaternion.identity; joystick_right_down = false; } } }这段代码对吗

这段代码基本上是正确的，但是有一些小问题需要注意： 1. 在使用摇杆的方向时，你将水平和垂直轴的值直接赋给了一个Vector2变量。然而，LookRotation方法需要一个Vector3作为参数。所以你需要将y轴值改为0。修改后...

public void Move() { int stt = sun; scoreText.text = stt.ToString(); if (Input.GetKey(KeyCode.W)) { direction = 0; this.gameObject.GetComponent<SpriteRenderer>().sprite = prota[2]; this.gameObject.transform.Translate(Vector3.up * speed * Time.deltaTime); PlayFootstepSound(); } else if (Input.GetKey(KeyCode.S)) { this.gameObject.GetComponent<SpriteRenderer>().sprite = prota[0]; direction = 2; this.gameObject.transform.Translate(Vector3.down * speed * Time.deltaTime); } else if (Input.GetKey(KeyCode.D)) { direction = 3; this.gameObject.GetComponent<SpriteRenderer>().sprite = prota[1]; this.gameObject.transform.Translate(Vector3.right * speed * Time.deltaTime); } else if (Input.GetKey(KeyCode.A)) { direction = 1; this.gameObject.GetComponent<SpriteRenderer>().sprite = prota[3]; this.gameObject.transform.Translate(Vector3.left * speed * Time.deltaTime); } // 攻击 if (Input.GetMouseButtonDown(0)) { // 处理鼠标左键点击事件 GameObject ins = Instantiate(bulletPrefab); Vector2 clickPosition = Camera.main.ScreenToWorldPoint(Input.mousePosition); ins.GetComponent<Blogs>().clickPosition = clickPosition; if (direction == 0) { ins.transform.position = new Vector3(this.gameObject.transform.position.x, this.gameObject.transform.position.y + 0.15f); } else if (direction == 2) { ins.transform.position = new Vector3(this.gameObject.transform.position.x, this.gameObject.transform.position.y - 0.15f); } else if (direction == 3) { ins.transform.position = new Vector3(this.gameObject.transform.position.x + 0.15f, this.gameObject.transform.position.y); } else if (direction == 1) { ins.transform.position = new Vector3(this.gameObject.transform.position.x - 0.15f, this.gameObject.transform.position.y); } } }增加移动时循环播放的代码

你可以在 Move() 方法中添加一个 while 循环来实现循环播放脚步声音的效果，具体代码如下： public void Move() { int stt = sun; scoreText.text = stt.ToString(); while (true) { if (Input.GetKey(KeyCode...

public void Move() { int stt = sun; scoreText.text = stt.ToString(); if (Input.GetKey(KeyCode.W)) { direction = 0; this.gameObject.GetComponent<SpriteRenderer>().sprite = prota[2]; this.gameObject.transform.Translate(Vector3.up * speed * Time.deltaTime); audioSource.Play(); } else if (Input.GetKey(KeyCode.S)) { audioSource.Play(); this.gameObject.GetComponent<SpriteRenderer>().sprite = prota[0]; direction = 2; this.gameObject.transform.Translate(Vector3.down * speed * Time.deltaTime); } else if (Input.GetKey(KeyCode.D)) { direction = 3; this.gameObject.GetComponent<SpriteRenderer>().sprite = prota[1]; this.gameObject.transform.Translate(Vector3.right * speed * Time.deltaTime); } else if (Input.GetKey(KeyCode.A)) { direction = 1; this.gameObject.GetComponent<SpriteRenderer>().sprite = prota[3]; this.gameObject.transform.Translate(Vector3.left * speed * Time.deltaTime); } // 攻击 if (Input.GetMouseButtonDown(0)) { // 处理鼠标左键点击事件 GameObject ins = Instantiate(bulletPrefab); Vector2 clickPosition = Camera.main.ScreenToWorldPoint(Input.mousePosition); ins.GetComponent<Blogs>().clickPosition = clickPosition; if (direction == 0) { ins.transform.position = new Vector3(this.gameObject.transform.position.x, this.gameObject.transform.position.y + 0.15f); } else if (direction == 2) { ins.transform.position = new Vector3(this.gameObject.transform.position.x, this.gameObject.transform.position.y - 0.15f); } else if (direction == 3) { ins.transform.position = new Vector3(this.gameObject.transform.position.x + 0.15f, this.gameObject.transform.position.y); } else if (direction == 1) { ins.transform.position = new Vector3(this.gameObject.transform.position.x - 0.15f, this.gameObject.transform.position.y); } } }优化代码并且增加脚步声
