[MAX 脚本]

max 脚本(经验总结) [复制链接]

2个工作日 ApeqbD5g&  
写了一套简单的Export/Import插件 bc'Io
D/  
一直对MAX的 Script感到很好奇 P\ke%Jdpw?  
说说使用的感受吧。 Mww^  
lEFd^@t  
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 1$vGQ  
MAX中很多概念不同于平常熟知的 RealTime里面的思想 ,7&\jET5^0  
例如，MAX中的纹理坐标，每个顶点都有一对UV 这个很正常 z:#]P0  
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 |z=`Ur@)  
等等 CXuD%H]tx  
[_)`G*X(N  
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。 ^~[7])}g6  
Qt+D ,X  
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 Ea@0>_U|  
G7 UUx+X  
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。 XZ |L D#  
Zmyq6.1q~  
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。 :b44LXKCP  
U7x  
第六 Max Script的函数 没有明确的返回值的概念，不习惯 #EzhtuHxn  
*LB-V%{|'  
第七 那个调试器 太难用了，我打了无数个messagebox Z3TC
i7,m  
swj\X,{  
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。 ^s6~*n<fH

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， $JOz7j(  
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 Wm
d@%K  
导入插件没什么特别的操作，导入插件结尾有些仓促 ELwXp|L

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 !6|_`l>G,
