Unity實現瞄準鏡效果
本文實例為大傢分享瞭Unity實現瞄準鏡效果的具體代碼,供大傢參考,具體內容如下
using UnityEngine; using System.Collections; public class TelesopicView : MonoBehaviour { public float zoomLevel = 2.0f; public float zoomInSpeed = 100.0f; public float zoomOutSpeed = 100.0f; private float initFOV; public GameObject obj; void Start() { //獲取當前攝像機的視野范圍 unity默認值60 initFOV = Camera.main.fieldOfView; } void Update() { if (Input.GetMouseButton(0)) { ZoomInView(); //激活ui窗口 obj.SetActive(true); } else { ZoomOutView(); //失活ui窗口 obj.SetActive(false); } } //放大攝像機的視野區域 void ZoomInView() { if (Mathf.Abs(Camera.main.fieldOfView - (initFOV / zoomLevel)) < 0f) { Camera.main.fieldOfView = initFOV / zoomLevel; } else if (Camera.main.fieldOfView - (Time.deltaTime * zoomInSpeed) >= (initFOV / zoomLevel)) { Camera.main.fieldOfView -= (Time.deltaTime * zoomInSpeed); } } //縮小攝像機的視野區域 void ZoomOutView() { if (Mathf.Abs(Camera.main.fieldOfView - initFOV) < 0f) { Camera.main.fieldOfView = initFOV; } else if (Camera.main.fieldOfView + (Time.deltaTime * zoomOutSpeed) <= initFOV) { Camera.main.fieldOfView += (Time.deltaTime * zoomOutSpeed); } } }
此腳本掛到unity主相機即可,可通過更改zoomLevel更改倍鏡倍數
以上就是本文的全部內容,希望對大傢的學習有所幫助,也希望大傢多多支持WalkonNet。
