## 资源准备
### 1. 准备好透明底的贴图
### 2. 创建材质 - 技能光圈
* 贴图拉进材质编辑器 `Multiply Particle Color` ,结果作为 自发光颜色
* 同样 Multiply 透明度通道,作为 `不透明度 Opacity`
* Material
* `Blend Mode = Translucent`
* `Shading Model = Unlit`
### 3. 创建材质 - 技能中心光点效果
* Material 同理设置
* Multiply 下两项,结果连到 自发光颜色、不透明度
* Particle Color
* `RadialGradientExponential`
## 技能光圈 - 粒子系统
* 材质使用刚创建的材质
* 粒子系统编辑器
* Required
* Material 应用材质
* Duration - `Emitter Duration = 0` 多少秒生成一次
* Spawn
* Rate - Distribution - `Constant = 0`
* Rate Scale - Distribution - `Constant = 0`
* Burst - Burst List 添加元素 - `Count = 1`
* 不需要 velocity ,删掉
* Lifetime - Distribution - `Distribution Float Constant - Constant = 0`
* Color Over Life
* Alpha Over Life - Distribution - `Distribution Float Constant - Constant = 1` 始终显示
* 对应材质中添加的 `Particle Color` 结点,Color Over Life - `Distribution = Distribution Vector Constant` - `具体颜色`
* 右键添加 `Orientation - Locak Axis - Lock Axis Flags = Z`
* 右键添加 `Size - Initial Size` - Distribution = Distribution Vector Constant - `X = 500`
* 右键添加 **`Light`** - Brightness Over Life 亮度、Color Scale Over Life 光的颜色、Radius Scale 范围
## 技能中心光点效果
* 在技能光圈的粒子系统编辑器 - 发射器 - 右键 `新建 Particle Sprite Emitter`
* 在 Required - Material 应用相应材质
* Initial Size - Distribution Vector Uniform - `Max = (25, 25, 25)、Min = (10, 10, 10)`
* Color Over Life - Distribution = Constant - 调颜色
* 右键添加 Initial Location - Distribution = Uniform - `Max = (150, 150, 0)、Min = (-150, -150, 0)`
