unity3d FPS 枪的后座力

实现枪开枪后, 向上偏移一段距离，再缓慢下移复位(模仿cs)

调小后座力

using UnityEngine; using System.Collections;public class Camera2Follower : MonoBehaviour {// 枪cd计时器float timer;// 后座力 之前枪摄像头的角度Vector3 s_pre_euler;public float gun_end_force = 0.53f; // 枪后座力大小 （可以先调大些方便调试）void Update (){....timer += Time.deltaTime;if (Input.GetButton("Fire1") && timer >= 0.15){// 计时器清零timer = 0f;s_pre_euler = transform.eulerAngles;// 后座力rotationY += Input.GetAxis("Mouse Y") * sensitivityY + gun_end_force;Quaternion yQuaternion2 = Quaternion.AngleAxis(rotationY, Vector3.left);transform.localRotation = originalRotation * yQuaternion2;}// 检测鼠标有没有移动if (Input.GetAxis("Mouse Y") != 0){//Debug.Log("X: " + transform.eulerAngles);s_pre_euler = transform.eulerAngles;rotationY += Input.GetAxis("Mouse Y") * sensitivityY;rotationY = ClampAngle(rotationY, minimumY, maximumY);Quaternion yQuaternion = Quaternion.AngleAxis(rotationY, Vector3.left);transform.localRotation = originalRotation * yQuaternion;}else{recoverGun();}}// 恢复后座力以前的位置void recoverGun() {s_pre_euler.y = transform.eulerAngles.y;Quaternion current_cam = Quaternion.Euler(transform.eulerAngles);Quaternion target_cam = Quaternion.Euler(s_pre_euler);transform.eulerAngles = Quaternion.Slerp(current_cam, target_cam, 5 * Time.deltaTime).eulerAngles;}void Start (){s_pre_euler = transform.eulerAngles;}// 限制角度public static float ClampAngle (float angle, float min, float max){if (angle < -360F)angle += 360F;if (angle > 360F)angle -= 360F;return Mathf.Clamp (angle, min, max);} }

看了一下cs的枪后座力 发现还有左右抖动，于是又加了点代码

y_angle_mat = xxxxxxxx; // 上下方向 .... // 在枪开火的方法区加 float xAngle = Random.Range(0.0f,1.0f); Quaternion x_angle_mat = Quaternion.AngleAxis(xAngle, Vector3.up); transform.localRotation = originalRotation * y_angle_mat * x_angle_mat; // 相当于乘以一个矩阵
