ParticleEmitter Class
​

粒子特效

通常用于游戏场景中的效果表现，目前开放部分粒子效果，当编辑器细节面板勾选自动启用时，运行游戏会自动播放特效。

如需精确控制特效的播放与停止，请使用 play 和 stop 方法。该特效需要手动控制生命周期，效果可通过细节面板中参数调节。

使用示例:创建一个名为"EffectExample"的脚本，拖拽到对象栏特效下，打开脚本，输入以下代码保存，运行游戏，你将在场景中看到粒子的变化效果。代码如下：
ts
@Component
export default class EffectExample extends Script {

    protected onStart(): void {

         let Effect = this.gameObject as ParticleEmitter;
         // 涉及部分对生命周期内效果的修改
         // 创建尺寸生命周期数组 效果为由蓝线性过度至红色
         let ColorSequence = Array<mw.colorSequencePoint>();
         // 生命周期0%时为蓝色 详见LinearColor
         ColorSequence.push(new mw.colorSequencePoint(0, new LinearColor(1,0,0)));
         // 生命周期100%时为红色
         ColorSequence.push(new mw.colorSequencePoint(0, new LinearColor(0,0,1)));
         Effect.color = ColorSequence;
         // 创建透明度生命周期数组 效果为逐渐清晰
         let TransparencySequence = Array<mw.numberSequencePoint>();
         // 刚生成时透明度为0 看不见
         TransparencySequence.push(new mw.numberSequencePoint(0, 0));
         // 逐渐过渡到生命周期末 全显示
         TransparencySequence.push(new mw.numberSequencePoint(1, 1));
         Effect.transparency = TransparencySequence;

         // 创建尺寸生命周期数组 效果为变大再缩小
         let SizeSequence = Array<mw.numberSequencePoint>();
         // 生命周期0%时大小为0
         Size
         // 生命周期50%时大小为4
         SizeSequence.push(new mw.numberSequencePoint(0.5, 4));
         // 生命周期100%时大小回到0
         SizeSequence.push(new mw.numberSequencePoint(1, 0));
         Effect.size = SizeSequence;

         // 设置特效阻力为1
         Effect.drag = 1;
         // 增加特效生成的速度
         Effect.rate = 100;
         // 不进行边缘裁剪,全部保留,方形
         Effect.maskRadius = 1;
         // 仅在表面生成
         Effect.shapeStyle = mw.ParticleEmitterShapeStyle.OnlySurface;
         // 生成范围长宽高100
         Effect.shapeExtents = new Vector(100, 100, 100);

         // 生命周期在1~10范围内随机
         Effect.lifetime = new Vector2(1, 10);
         // 10秒后停止, 不影响已生成粒子
         setTimeout(() => {
             Effect.stop();
         }, 10000);
    }
}
