学习MAXScript

MaxScript – a Comprehensive Introduction

基础语法

select $Box* – select any objects with the name box at the beginning of them.

打开MAXScript侦听器窗口，开启宏录制器。

这样，每当我们进行一个操作，比如创建一个Box，那么宏录制器中会显示当前动作所对应的MAXScript命令。

Use Loop

注意， $ 中的元素顺序与你选择的时候的顺序相关联。

while loop and if condition

function

fn TalkToMe = ( Messagebox "hello" ) fn RotateMe obj xamount = ( obj.rotation.x_rotation += xamount ) --RotateMe $* 90 -- everything --RotateMe $Box* 90 -- Box... RotateMe $*01 90

function with return

3个函数，3中类型

fn TalkToMe = ( Messagebox "hello" ) fn RotateMe obj xamount = ( obj.rotation.x_rotation += xamount ) fn BoundingVolume obj = ( (obj.max.x - obj.min.x) * (obj.max.y - obj.min.y) * (obj.max.z - obj.min.z) -- return a value ) --print(BoundingVolume $) for o in $ do ( if(BoundingVolume o) > 5000 do ( print ("found a whopper called " + o.name as string) ) ) 

一个例子，用到了 rollout

代码在这里

我的实践

phase1

--importing multiple *.obj extensions in a directory fn getFilesOBJ directory = ( for f in ( getFiles (directory + "*.obj")) do ( lokatie = f as string file = getFilenameFile f --pak de naam van bestand print file importFile lokatie #noPrompt --FN import obj $selection[1].name = file --将该对象重命名为文件名（不包括 .obj 后缀） ) ) filename = getOpenFileName types:"OBJ(*.obj)|*.obj" --得到文件名 directory = getFilenamePath filename --得到该文件所在目录名 getfilesOBJ directory --读取该目录下的所有 .obj 文件 --将 MaterialEditor 中的 material 加载到相应的对象上。（此前已经将material的名字设定为对应object的名字） for o in $*trans do ( for m in meditmaterials do ( if o.name == m.name then o.mat = m ) )

注：导入.obj文件将不会打开交互窗口，将会沿用之前的设置，为了使图像导入为 flat 而不是 smooth 风格，需要注意下面的那个选项

phase 2

-- animate On -- ( -- at time 0f($uppart_trans.pos=[0,0,0]; $uppart_trans.scale=[1,1,0.25]) -- -- at time 100f($uppart_trans.pos=[100,0,0]; $uppart_trans.scale=[1,1,3]) -- )

其它的一些积累

使用 string 来选取对象，这里需要用到 getNodeByName 函数

--If your variable "a" refer to the object itself: a = $Box01 select a --But if "a" is just the name as string then: a = "Box01" select (getNodeByName a)
