[MAX 脚本]

max 脚本(经验总结) [复制链接]

2个工作日 Cn6n4, 0  
写了一套简单的Export/Import插件 \>aa8LOe  
一直对MAX的 Script感到很好奇 \gJapx(  
说说使用的感受吧。 &4[#_(pk  
`ykMh>*{  
首先，如果要使用这套Script那么 首先会陷入到庞大的MAX的概念的汪洋大海之中 f!uA$uLc  
MAX中很多概念不同于平常熟知的 RealTime里面的思想 Z+`{JE#  
例如，MAX中的纹理坐标，每个顶点都有一对UV 这个很正常 b*6c.o  
但是同时 MAX对每个Face也保存了UV，这是因为MAX中的 每个Face都有可能是不同的贴图 0c\|S>g[  
等等 D<D k1  
xP5mL3j  
第二，如果熟悉了MAX中的哪些类能够干什么 那么Script也就是很水道渠成的事情了。为了写这2个插件，MAX Script 的help翻了无数次，几乎每写一句就要去翻一次。 &=6cz$]z  
nX.sh  
第三，MAX中的数组起位置是1，但是MAX中有的概念 使用数组表示的时候起始位置为0 ，例如纹理的Channel，起始就是为0，并且Channel0  很危险，写入错误直接让MAX挂掉 wTMHoU*>  
&"H<+>`  
第四，脚本编写很考验打字的准确度，由于变量没有类型，不需要声明就可以试用，打错一个字母的话那就查吧，运气不好的话，会让你疯掉的，同时MAX的脚本编辑器 超级难用。 }JpslY*aS  
p$b=r+1f  
第五，编写导入插件的时候，发现Script 中读入数据异常痛苦，我在Script的帮助中没有发现任何类似c语言中的fprintf(%...)的东西，只有通过脚本提供的skiptostring来做。 hO<w]jV,  
\Q?|gfJH  
第六 Max Script的函数 没有明确的返回值的概念，不习惯 +'&_V011<  
%6c*dy  
第七 那个调试器 太难用了，我打了无数个messagebox UN .[,
%<s  
^* /v,+01f  
总结：对于导入导出插件来说其实用SDK和Script 编写其实差别不大，因为都只是涉及到数据的读取和写入，并不涉及到复杂的逻辑。如果编写渲染类型或者是动画控制类型的插件 我觉得还是用script好一些，因为可以直接在MAX中看到结果，同时还能够一句一句的执行，很方便。 ]x(2}h^

我只是初学，希望有经验的人给点经验，最后附上简单的插件代码， l^eNZ3:H  
导出插件只能到处一个几何体，点击ExportGeo按钮，然后点选几何体，即可输出 luz%FY:  
导入插件没什么特别的操作，导入插件结尾有些仓促 ?D^,K`wY=B  
I#hg(7|",  
以下是导入插件：其实导入插件没什么必要写，反正是在MAX中建模，直接保存为MAX文件就可以了，这里 gc8PA_bFz
