5.5 之前的粒子系统变量可以通过 ParticleSystem 访问并被读/写。现在可以通过 ParticleSystem.MainModule 访问它们因此很多代码已经过时了。 API Updater无法解决大部分问题。我已经通读了新文档,但无法弄清楚应该如何使用新变量类型。例如,在 JetParticleEffect.cs 中,此行会导致警告:
// set the original properties from the particle system
m_OriginalLifetime = m_System.startLifetime;
警告状态:“ParticleSystem.startLifetime”已过时:“startLifetime 属性已弃用。请改用 main.startLifetime 或 main.startLifetimeMultiplier。'
我试过以下方法:
m_OriginalLifetime = m_System.main.startLifetime;
// error: Cannot implicitly convert type 'UnityEngine.ParticleSystem.MinMaxCurve' to 'float'
我相信答案与 minMaxCurve constant 有关编译时的变量:
m_OriginalLifetime = m_System.main.startLifetime.constant;
但是文档中几乎没有解释。任何人都可以阐明这一点吗?
此外,新的乘数适用于何处?我假设您以前可以在哪里执行此操作:
particle.startSize *= myMultiplier
...你现在应该这样做吗?
particle.main.startSizeMultiplier = myMultiplier
最佳答案
particle.startLifetime:
首先,Unity 在 Unity 5.5 中所做的是为 ParticleSystem
添加新的 future 。 .他们还暴露了一些ParticleSystem
之前隐藏的API。
ParticleSystem.MainModule.startLifetime
现在是 MinMaxCurve
的一种而不是像 ParticleSystem.startLifetime
那样 float .
通过这样做,您现在可以获得更多选项,例如修改 startLifetime
作为曲线。
读取或写入 ParticleSystem.MainModule.startLifetime
取决于 ParticleSystem.MainModule.startLifetime.mode
的值这是通过编辑器或通过代码设置的。
默认值ParticleSystem.MainModule.startLifetime.mode
是 ParticleSystemCurveMode.Constant
所以你的 m_OriginalLifetime = m_System.main.startLifetime.constant;
很好。
如果startLifetime
在运行时动态或随机更改为另一种模式,那么您将必须执行如下操作:
ParticleSystem m_System = GetComponent<ParticleSystem>();
ParticleSystem.MainModule main = m_System.main;
ParticleSystem.MinMaxCurve minMaxCurve = main.startLifetime;
if (minMaxCurve.mode == ParticleSystemCurveMode.Constant)
{
m_OriginalLifetime = m_System.main.startLifetime.constant;
}
else if (minMaxCurve.mode == ParticleSystemCurveMode.Curve)
{
AnimationCurve animCurveLifetime = m_System.main.startLifetime.curve;
}
...
particle.startSize:
同样的事情适用于 particle.startSize
.
particle.startSize
属性(property)现m_System.main.startSize;
虽然你不能做m_System.main.startSize.constant *= myMultiplier;
因为你的旧密码是 particle.startSize *= myMultiplier
.
你需要得到 m_System.main.startSize
, 修改它然后分配修改后的 m_System.main.startSize
返回m_System.main.startSize
.
particle.startSize *= myMultiplier
应该是:
ParticleSystem m_System = GetComponent<ParticleSystem>();
ParticleSystem.MainModule main = m_System.main;
ParticleSystem.MinMaxCurve minMaxCurve = main.startSize; //Get Size
minMaxCurve.constant *= myMultiplier; //Modify Size
main.startSize = minMaxCurve; //Assign the modified startSize back
然后,什么是particle.main.startSizeMultiplier
和 particle.main.startSize
用于?
这两个变量也可以用来改变startLifetime
和 startSize
.它的主要优点是非常高效。它不需要您复制 MinMaxCurve
就像我们上面做的那样,为了改变startSize
或 startSizeMultiplier
.
ParticleSystem m_System = GetComponent<ParticleSystem>();
ParticleSystem.MainModule main = m_System.main;
main.startSizeMultiplier = 5;
和
ParticleSystem m_System = GetComponent<ParticleSystem>();
ParticleSystem.MainModule main = m_System.main;
main.startLifetimeMultiplier = 8;
如果您的 ParticleSystem.MainModule.startLifetime.mode
使用它们是常数。这将有效地改变总体生命周期乘数或总体大小乘数。
改变颜色和颜色模式
颜色:
有一个隐式运算符可让您使用:
ParticleSystem.MainModule main = trailPartical.main;
main.startColor = Color.red;
但是startColor
实际上不是 Color
的类型. startColor
变量现在是 ParticleSystem.MinMaxGradient
的一种类型.
这就是你应该如何改变粒子 startColor
:
//Create Color
ParticleSystem.MinMaxGradient color = new ParticleSystem.MinMaxGradient();
color.mode = ParticleSystemGradientMode.Color;
color.color = Color.red;
//Assign the color to your particle
ParticleSystem.MainModule main = trailPartical.main;
main.startColor = color;
渐变:
public ParticleSystem particleSystem;
void Start()
{
//Create Gradient key
GradientColorKey[] gradientColorKey;
gradientColorKey = new GradientColorKey[3];
gradientColorKey[0].color = Color.red;
gradientColorKey[0].time = 0f;
gradientColorKey[1].color = Color.blue;
gradientColorKey[1].time = 0.5f;
gradientColorKey[2].color = Color.green;
gradientColorKey[2].time = 1f;
//Create Gradient alpha
GradientAlphaKey[] gradientAlphaKey;
gradientAlphaKey = new GradientAlphaKey[3];
gradientAlphaKey[0].alpha = 1.0f;
gradientAlphaKey[0].time = 0.0f;
gradientAlphaKey[1].alpha = 0.5f;
gradientAlphaKey[1].time = 0.5f;
gradientAlphaKey[2].alpha = 1f;
gradientAlphaKey[2].time = 1f;
//Create Gradient
Gradient gradient = new Gradient();
gradient.SetKeys(gradientColorKey, gradientAlphaKey);
//Create Color from Gradient
ParticleSystem.MinMaxGradient color = new ParticleSystem.MinMaxGradient();
color.mode = ParticleSystemGradientMode.Gradient;
color.gradient = gradient;
//Assign the color to particle
ParticleSystem.MainModule main = particleSystem.main;
main.startColor = color;
}
两种颜色之间随机:
//Create Color from Gradient
ParticleSystem.MinMaxGradient color = new ParticleSystem.MinMaxGradient();
color.mode = ParticleSystemGradientMode.TwoColors;
color.colorMin = Color.red;
color.colorMax = Color.green;
//Assign the color to the particle
ParticleSystem.MainModule main = particleSystem.main;
main.startColor = color;
两个梯度之间的随机:
public ParticleSystem particleSystem;
void Start()
{
//Create Gradient key Min
GradientColorKey[] gradientColorKeyMin;
gradientColorKeyMin = new GradientColorKey[3];
gradientColorKeyMin[0].color = Color.red;
gradientColorKeyMin[0].time = 0f;
gradientColorKeyMin[1].color = Color.blue;
gradientColorKeyMin[1].time = 0.5f;
gradientColorKeyMin[2].color = Color.green;
gradientColorKeyMin[2].time = 1f;
//Create Gradient alpha Min
GradientAlphaKey[] gradientAlphaKeyMin;
gradientAlphaKeyMin = new GradientAlphaKey[3];
gradientAlphaKeyMin[0].alpha = 1.0f;
gradientAlphaKeyMin[0].time = 0.0f;
gradientAlphaKeyMin[1].alpha = 0.5f;
gradientAlphaKeyMin[1].time = 0.5f;
gradientAlphaKeyMin[2].alpha = 1f;
gradientAlphaKeyMin[2].time = 1f;
//Create Gradient key Max
GradientColorKey[] gradientColorKeyMax;
gradientColorKeyMax = new GradientColorKey[3];
gradientColorKeyMax[0].color = Color.red;
gradientColorKeyMax[0].time = 0f;
gradientColorKeyMax[1].color = Color.blue;
gradientColorKeyMax[1].time = 0.5f;
gradientColorKeyMax[2].color = Color.green;
gradientColorKeyMax[2].time = 1f;
//Create Gradient alpha Max
GradientAlphaKey[] gradientAlphaKeyMax;
gradientAlphaKeyMax = new GradientAlphaKey[3];
gradientAlphaKeyMax[0].alpha = 1.0f;
gradientAlphaKeyMax[0].time = 0.0f;
gradientAlphaKeyMax[1].alpha = 0.5f;
gradientAlphaKeyMax[1].time = 0.5f;
gradientAlphaKeyMax[2].alpha = 1f;
gradientAlphaKeyMax[2].time = 1f;
//Create Gradient Min
Gradient gradientMin = new Gradient();
gradientMin.SetKeys(gradientColorKeyMin, gradientAlphaKeyMin);
//Create Gradient Max
Gradient gradientMax = new Gradient();
gradientMax.SetKeys(gradientColorKeyMax, gradientAlphaKeyMax);
//Create Color from Gradient
ParticleSystem.MinMaxGradient color = new ParticleSystem.MinMaxGradient();
color.mode = ParticleSystemGradientMode.TwoGradients;
color.gradientMin = gradientMin;
color.gradientMax = gradientMax;
//Assign the color to the particle
ParticleSystem.MainModule main = particleSystem.main;
main.startColor = color;
}
随机颜色:
public ParticleSystem particleSystem;
void Start()
{
//Create Gradient key Min
GradientColorKey[] gradientColorKeyMin;
gradientColorKeyMin = new GradientColorKey[3];
gradientColorKeyMin[0].color = Color.red;
gradientColorKeyMin[0].time = 0f;
gradientColorKeyMin[1].color = Color.blue;
gradientColorKeyMin[1].time = 0.5f;
gradientColorKeyMin[2].color = Color.green;
gradientColorKeyMin[2].time = 1f;
//Create Gradient alpha Min
GradientAlphaKey[] gradientAlphaKeyMin;
gradientAlphaKeyMin = new GradientAlphaKey[3];
gradientAlphaKeyMin[0].alpha = 1.0f;
gradientAlphaKeyMin[0].time = 0.0f;
gradientAlphaKeyMin[1].alpha = 0.5f;
gradientAlphaKeyMin[1].time = 0.5f;
gradientAlphaKeyMin[2].alpha = 1f;
gradientAlphaKeyMin[2].time = 1f;
//Create Gradient key Max
GradientColorKey[] gradientColorKeyMax;
gradientColorKeyMax = new GradientColorKey[3];
gradientColorKeyMax[0].color = Color.red;
gradientColorKeyMax[0].time = 0f;
gradientColorKeyMax[1].color = Color.blue;
gradientColorKeyMax[1].time = 0.5f;
gradientColorKeyMax[2].color = Color.green;
gradientColorKeyMax[2].time = 1f;
//Create Gradient alpha Max
GradientAlphaKey[] gradientAlphaKeyMax;
gradientAlphaKeyMax = new GradientAlphaKey[3];
gradientAlphaKeyMax[0].alpha = 1.0f;
gradientAlphaKeyMax[0].time = 0.0f;
gradientAlphaKeyMax[1].alpha = 0.5f;
gradientAlphaKeyMax[1].time = 0.5f;
gradientAlphaKeyMax[2].alpha = 1f;
gradientAlphaKeyMax[2].time = 1f;
//Create Gradient Min
Gradient gradientMin = new Gradient();
gradientMin.SetKeys(gradientColorKeyMin, gradientAlphaKeyMin);
//Create Gradient Max
Gradient gradientMax = new Gradient();
gradientMax.SetKeys(gradientColorKeyMax, gradientAlphaKeyMax);
//Create Color from Gradient
ParticleSystem.MinMaxGradient color = new ParticleSystem.MinMaxGradient();
color.mode = ParticleSystemGradientMode.RandomColor;
color.gradientMin = gradientMin;
color.gradientMax = gradientMax;
//Assign the color to the particle
ParticleSystem.MainModule main = particleSystem.main;
main.startColor = color;
}
