我想知道如何使用c#平滑放大并平滑缩小Unity3d中的按钮按下。 我已经缩小了部分,但不知道如何进行放大和缩小的过渡。 作为一个例子,我希望它能像ARMA或DayZ游戏一样平滑放大。
这是我的代码:
using System.Collections; using System.Collections.Generic; using UnityEngine; public class zoomIN : MonoBehaviour { public Camera cam; // Use this for initialization void Start () { } // Update is called once per frame void Update () { if (Input.GetMouseButton (1)) { cam.fieldOfView = 20; } if (Input.GetMouseButtonUp (1)) { cam.fieldOfView = 60; } } }我很感激任何帮助! 谢谢,圣诞快乐!
I'm wondering how to smoothly zoom in and smoothly zoom out on button press in Unity3d using c#. I've got zooming part down already, but not sure how to make a transition of zooming in and out smooth. As an example, I'd like it to zoom in as smooth as it is in ARMA or DayZ game.
Here's my code:
using System.Collections; using System.Collections.Generic; using UnityEngine; public class zoomIN : MonoBehaviour { public Camera cam; // Use this for initialization void Start () { } // Update is called once per frame void Update () { if (Input.GetMouseButton (1)) { cam.fieldOfView = 20; } if (Input.GetMouseButtonUp (1)) { cam.fieldOfView = 60; } } }I'd appreciate any help! Thanks and Merry Xmas!

使用协同程序来执行此操作。 您可以使用它来启用缩放的速度或持续时间。 在cam.fieldOfView和目标( 20或60 )之间执行Mathf.Lerp ,具体取决于是否按下或释放了键。
注意:您必须将Input.GetMouseButton更改为Input.GetMouseButtonDown否则您的第一个if语句将在按住鼠标右键的同时每帧运行。 我想你只想做一次 。
public Camera cam; Coroutine zoomCoroutine; // Update is called once per frame void Update() { if (Input.GetMouseButtonDown(1)) { //Stop old coroutine if (zoomCoroutine != null) StopCoroutine(zoomCoroutine); //Start new coroutine and zoom within 1 second zoomCoroutine = StartCoroutine(lerpFieldOfView(cam, 20, 1f)); } if (Input.GetMouseButtonUp(1)) { //Stop old coroutine if (zoomCoroutine != null) StopCoroutine(zoomCoroutine); //Start new coroutine and zoom within 1 second zoomCoroutine = StartCoroutine(lerpFieldOfView(cam, 60, 1f)); } } IEnumerator lerpFieldOfView(Camera targetCamera, float toFOV, float duration) { float counter = 0; float fromFOV = targetCamera.fieldOfView; while (counter < duration) { counter += Time.deltaTime; float fOVTime = counter / duration; Debug.Log(fOVTime); //Change FOV targetCamera.fieldOfView = Mathf.Lerp(fromFOV, toFOV, fOVTime); //Wait for a frame yield return null; } }Use coroutine to do this. You can use it to enable the speed or duration of the zooming. Perform a Mathf.Lerp between cam.fieldOfView and the destination( 20 or 60) depending on if the key is pressed or released.
Note: You must change Input.GetMouseButton to Input.GetMouseButtonDown otherwise your first if statement will be running every frame while the right mouse button is held down. I think you want to be true once only.
public Camera cam; Coroutine zoomCoroutine; // Update is called once per frame void Update() { if (Input.GetMouseButtonDown(1)) { //Stop old coroutine if (zoomCoroutine != null) StopCoroutine(zoomCoroutine); //Start new coroutine and zoom within 1 second zoomCoroutine = StartCoroutine(lerpFieldOfView(cam, 20, 1f)); } if (Input.GetMouseButtonUp(1)) { //Stop old coroutine if (zoomCoroutine != null) StopCoroutine(zoomCoroutine); //Start new coroutine and zoom within 1 second zoomCoroutine = StartCoroutine(lerpFieldOfView(cam, 60, 1f)); } } IEnumerator lerpFieldOfView(Camera targetCamera, float toFOV, float duration) { float counter = 0; float fromFOV = targetCamera.fieldOfView; while (counter < duration) { counter += Time.deltaTime; float fOVTime = counter / duration; Debug.Log(fOVTime); //Change FOV targetCamera.fieldOfView = Mathf.Lerp(fromFOV, toFOV, fOVTime); //Wait for a frame yield return null; } }更多推荐
