如何翻译shader graph到代码并添加额外的效果
使用shader graph翻译到代码可以使用连线工具快速制作效果并转换为代码，如果你对shader的“贴心/详细”报错，以及提示不完善等等问题感到恼火，这个方式或许可以一定程度上缓解以上问题。
本次使用的三个shader graph资源：https://download.csdn.net/download/qq_55895529/88489974?spm=1001.2014.3001.5503
首先这里有一个这样效果的shader graph
参数如下
赋值shader graph的代码，代码非常多且其中有很多个pass，取其第一个pass的内容。

} 这里面一共有三个主要的方法，正常来说shadergraph翻译出来的代码只有一个主要的方法，方法名称为：SurfaceDescriptionFunction
这个方法中包含了所有的计算流程，这里面有三个主要是因为这个shader graph的计算中使用了两个sub graph，也就是说相当于是三个shader graph，所以有三个方法
两个sub graph方法分别为SG_FlowMapComputeUV_b1858d7f2791c414298ed47e2e3f717e_float和SG_FlowMapSampleTexture_e2dd025b49c90924ba82331e75f4f6d3_float，这里简称为FlowMapComputeUV和FlowMapSampleTexture，一个是为了计算流动图的uv，一个是根据计算出的uv采样流动图。
分别翻译一下这三个主要方法，把复杂的变量名称替换为熟悉易读的名称。

点击相应效果在附带文件中的名为ForceField的shader graph

}有些交互计算需要的变量输入要添加一下
通过数组参数循环添加到目前的颜色计算中，最终代码为这样
