Unity（1）
这篇文章我们讨论一下如何通过&Camera来制作一个瞄准镜的效果，玩射击类游戏比较多的朋友大概就能感觉出来这个功能大致的实现效果如何了。
主要的方法就是通过调整&Camera的&Field Of View，让其渐大渐小来实现
当我们瞄准的时候，我们只需要将&Field&Of&View&变小，停止瞄准的时候，再将Field Of View&恢复成原来的大小
if (Mathf.Abs(Camera.main.fieldOfView-(initFOV/ZoomLevel))&0.5f)
Camera.main.fieldOfView = initFOV/ZoomL
}else if (Camera.main.fieldOfView-(Time.deltaTime*ZoomInSpeed)&=initFOV/ZoomLevel)
Camera.main.fieldOfView -= Time.deltaTime*ZoomInS
}if (Mathf.Abs(Camera.main.fieldOfView - (initFOV/ZoomLevel)) & 0.5f)
Camera.main.fieldOfView = initFOV;
}else if (Camera.main.fieldOfView+(Time.deltaTime*ZoomOutSpeed)&=initFOV)
Camera.main.fieldOfView += Time.deltaTime*ZoomOutS
效果如下：瞄准前
简单的效果大致是有了，但是总觉得有些不足，我们实际上可以 瞄准时候只在圆圈方位内显示所看到的物体
还好，我们的Unity&为我们提供了&Image&Effect&制作后期效果的资源包，可以把&&Vignetting脚本附加到&Camera上，然后通过在脚本中&控制&Vignetting&实例的&intensity来达到我们所想要的镜头的效果。
由于&Vignetting脚本是用&javascript编写的，CSharp&在引用它的时候，会没有智能提示，o(╯□╰)o，完整的代码如下：
public class TelescopicView : MonoBehaviour
public float ZoomLevel = 2;
public float ZoomInSpeed = 100f;
public float ZoomOutSpeed = 100f;
private float initFOV;
private float vignetteAmount = 10.0f;
// Use this for initialization
void Start()
initFOV = Camera.main.fieldOfV
vignette = GetComponent&Vignetting&();
// Update is called once per frame
void Update()
if (Input.GetMouseButton(1))
ZoomView();
ZoomOut();
private void ZoomView()
if (Mathf.Abs(Camera.main.fieldOfView-(initFOV/ZoomLevel))&0.5f)
Camera.main.fieldOfView = initFOV/ZoomL
vignette.intensity = vignetteA
}else if (Camera.main.fieldOfView-(Time.deltaTime*ZoomInSpeed)&=initFOV/ZoomLevel)
Camera.main.fieldOfView -= Time.deltaTime*ZoomInS
vignette.intensity = vignetteAmount * (Camera.main.fieldOfView - initFOV) / ((initFOV / ZoomLevel) - initFOV);
private void ZoomOut()
if (Mathf.Abs(Camera.main.fieldOfView - (initFOV/ZoomLevel)) & 0.5f)
Camera.main.fieldOfView = initFOV;
vignette.intensity = 0;
}else if (Camera.main.fieldOfView+(Time.deltaTime*ZoomOutSpeed)&=initFOV)
Camera.main.fieldOfView += Time.deltaTime*ZoomOutS
vignette.intensity = vignetteAmount * (Camera.main.fieldOfView - initFOV) / ((initFOV / ZoomLevel) - initFOV);
实现效果也贴出来：
是不是很生动啊。。。

Ferber's viewAt this age, your child has probably given up his morning nap, sleeping only for an hour or two after lunch. Any more than that may be too much and cut into his nighttime sleep. By their third birthday, most children are down to a single one- to two-hour afternoon nap after lunch, a pattern some keep until they're 5. Read more about the Ferber sleep method.
He recalls that immediately after the doors shut he began to curse and swear at his circumstances to the point of unzipping his pants, taking hold of his penis and shaking it around as if to taunt and ridicule the police for what they had done to him for years.
You: "Many people are concerned about that, but we structure things so that we get very high participation. If we can do that, it will really improve results, won't it?" The answer might go something like, "Well, if you can do that, it would definitely make a difference." You are building agreement and buy-in with every trial close.

专家：AlphaGo强在深度学习 实力还未达巅峰
The program has the potential to raise student achievement at every grade level, as better prepared students advance year to year. Bright Beginnings recognizes that as Elementary Education Standards increase, preschool student curriculum must as well. As the director of the program explains, "(Children) are expected to learn more. The standards have increased, not just in college and high school but in kindergarten too."!.
Her response to my admission of finding love was "Do you even know what love is?" Well, I didn't really, I thought it was just something you felt and when you thought of the same person enough times, you must be in love with them. This is where my mum enlightened me on what she had read was the definition of love, and I tend to agree.
