<h3 id="一、基本概念："><a href="#一、基本概念：" class="headerlink" title="一、基本概念："></a>一、基本概念：</h3><p>particle：分子，是Illusion基本构成元素</p>
<p>particle type：分子类型，决定分子的行为、颜色、速率、大小、重量等</p>
<p>Emitters：发射器，由单一或多个分子构成</p>
<p>Defiectors：偏向板，可见或不可见的障碍，分子会与之撞击</p>
<p>Bllgckers：隐藏板，舞台上的一个区域，分子进入后会不可见</p>
<h3 id="二、创建步骤："><a href="#二、创建步骤：" class="headerlink" title="二、创建步骤："></a>二、创建步骤：</h3><p>1）选中一个粒子放在舞台上</p>
<p>2）在时间轴上选定一个时间，然后拖放粒子</p>
<p>3）为止调节，必须在关键帧处，右键</p>
<p>4）保存</p>
<h3 id="三、粒子库"><a href="#三、粒子库" class="headerlink" title="三、粒子库"></a>三、粒子库</h3><pre><code>在粒子库区域右键，快速载入可有默认选择，载入粒子库可选择别处粒子库
</code></pre><h3 id="四、技法"><a href="#四、技法" class="headerlink" title="四、技法"></a>四、技法</h3><pre><code>舞台上单击右键，可调节背景色，拉近/远镜头（缩放），居中对齐等
在关键帧上添加粒子，邮件—>记录位置数据，可任意绘制路径供粒子移动
</code></pre><p>注：此路径在粒子结束前必须描绘完，并且只能修改粒子疏密而无法修改路径</p>
<p>技法（路径）</p>
<pre><code>在关键帧上右键—>弯曲，可调整曲度和张力，再右键选择连接时，左右拉杆关联，取消连接时，可单独调节。快捷键：alt
</code></pre><p>技法（速度）</p>
<pre><code>通过弯曲手柄调节，每个点均设成转角，用拉杆来调节疏密，越密越快！
</code></pre><h3 id="五、Emmitter常用属性："><a href="#五、Emmitter常用属性：" class="headerlink" title="五、Emmitter常用属性："></a>五、Emmitter常用属性：</h3><p>1）Active：用来决定何时产生particle</p>
<p>2）Life：生命周期，决定particle的消失时间</p>
<p>3）Size：表示particle的大小</p>
<p>4）Velocity：加速度，表示particle陪出后移动的速度</p>
<p>5）Weight：重量，用来控制particle降落的速度以及上升的速度 注2</p>
<p>6）Zoom：放大或缩小，也可用远近的感觉来形容</p>
<p>7）Tint & Tint strength：改变emitter内particle的颜色</p>
<p>8）Emission angle & Emission rang：喷射角度及喷射范围，用来决定<br> particle喷射的方向 注1</p>
<p>9）Number：喷出particle的数量</p>
<p>10）Spin：控制particle的旋转 （同注2，也必须调particle的属性）</p>
<p>注1：当Emission rang的值为360时，Emission angle的变化将看不出来，所以调整Emission角度之前，必须先调整Emission的范围（不能是360°）</p>
<p>注2：想调整weight，应调整particle的weight，而不是Emitter的weight，当particle的weight为正值则particle下落，为零时代表无重力状态，会向四面八方喷射，为负值则向上飘</p>
