您可以使用 Coroutines 和 WaitForSeconds 来实现这一目标
// onRatio and offRatio are "optional" parameters
// If not provided, they will simply have their default value 1
IEnumerator Flash(float frequency ,float onRatio = 1, float offRatio = 1)
{
float cycleDuration = 1.0f / frequency;
float onDuration = (onRatio/ (onRatio + offRatio)) * cycleDuration;
float offDuration = (offRatio/ (onRatio + offRatio)) * cycleDuration;
while(true)
{
show = true;
yield return new WatForSeconds(onDuration);
show = false;
yield return new WatForSeconds(offDuration);
}
}
所以你可以用一个频率来调用它，例如8赫兹
StartCoroutine(Flash(8.0f));
这实际上等于您设置 onRatio = offRatio 的任何调用，例如
StartCoroutine(Flash(8.0f, onRatio = 1, offRatio = 1));
StartCoroutine(Flash(8.0f, onRatio = 2, offRatio = 2));
....
或具有频率和比率，例如1（开）：2（关），8Hz
StartCoroutine(Flash(8.0f, onRatio = 1, offRatio = 2));
通过这种设置，协程在while(true)-loop 中“永远”运行。所以，在你启动一个新的 Coroutine 之前，不要忘记先用不同的参数停止所有的例程
StopAllCoroutines();
现在，如果您想在 Update 方法中动态更改它，则必须在 roder 中添加一些控制标志和其他变量，以确保仅在发生更改时才调用新的协程：
FlashRateInterval currentInterval;
float currentOnRatio = -1;
float currentOffRatio = -1;
void Update()
{
// if nothing changed do nothing
if(flashRate.herz == currentInterval
//todo && Mathf.Approximately(<yourOnRatio>, currentOnRatio)
//todo && Mathf.Approximately(<yourOffRatio>, currentOffRatio)
) return;
StopAllCoroutines();
currentInterval = flashRate.herz;
//todo currentOnRatio = <yourOnRatio>;
//todo currentOffRatio = <yourOffRatio>;
switch (flashRate.herz)
{
case FlashRateInterval.twoHerz:
StartCoroutine(2.0f);
//todo StartCoroutine(2.0f, onRatio = <yournRatio>, offRatio = <yourOffRatio>);
case FlashRateInterval.fourHerz:
StartCoroutine(4.0f);
//todo StartCoroutine(4.0f, onRatio = <yournRatio>, offRatio = <yourOffRatio>);
case FlashRateInterval.eightHerz:
StartCoroutine(8.0f);
//todo StartCoroutine(8.0f, onRatio = <yournRatio>, offRatio = <yourOffRatio>);
default:
show =true;
}
}
注意事项：
-
我不知道你的FlashRateInterval，但如果你出于某种原因需要使用它，你可以让它喜欢
public enum FlashRateInterval
{
AllwaysOn,
twoHerz = 2,
fourHerz = 4,
eightHerz = 8
}
为了直接使用正确的值。
我将调用频率变量flashRate.herz。您也不会调用大小值cube.meters。我建议将其重命名为 flashRate.frequency。
要实现同步，您需要以某种方式访问所有行为并比较它们的值（所以我会说一些 static List<YourBehavior>），而不是例如在协程中等到所有布尔值都为例如在继续你自己的之前设置为true。为此，您需要一个额外的布尔值，因为 show 可能在一个组件上永久为真。
public bool isBlinking;
IEnumerator Flash(float frequency ,float onRatio = 1, float offRatio = 1)
{
//todo: You'll have to set this false when not blinking -> in Update
isBlinking = true;
float cycleDuration = 1.0f / frequency;
float onDuration = (onRatio/ (onRatio + offRatio)) * cycleDuration;
float offDuration = (offRatio/ (onRatio + offRatio)) * cycleDuration;
// SYNC AT START
show = false;
// wait until all show get false
foreach(var component in FindObjectsOfType<YOUR_COMPONENT>())
{
// skip checking this component
if(component == this) continue;
// if the component is not running a coroutine skip
if(!component.isBlinking) continue;
// Now wait until show gets false
while(component.show)
{
// WaitUntilEndOfFrame makes it possible
// for us to check the value again already before
// the next frame
yield return new WaitForEndOfFrame;
}
}
// => this line is reached when all show are false
// Now lets just do the same but this time wating for true
// wait until all show get false
foreach(var component in FindObjectsOfType<YOUR_COMPONENT>())
{
// skip checking this component
if(component == this) continue;
// if the component is not running a coroutine skip
if(!component.isBlinking) continue;
// Now wait until show gets false
while(!component.show)
{
// WaitUntilEndOfFrame makes it possible
// for us to check the value again already before
// the next frame
yield return new WaitForEndOfFrame;
}
}
// this line is reached when all show are getting true again => begin of loop
while(true)
{
.........
除了使用有点慢的FindObjectsOfType<YOUR_COMPONENT>()，您还可以执行类似的操作
public static List<YOUR_COMPONENT> Components = new List<YOUR_COMPONENT>();
private void Awake()
{
if(!Components.Contains(this)){
Components.Add(this);
}
}
因此您还可以获得当前禁用的组件和对象
