- the MAXScript ten (or so) common words
< br /> the MAXScript can replace the implementation of a large number of routine operations tasks. As long as you master a few simple commands, you can put tens of millions of times a mouse operation instantly auto-complete, even with a whole new way to solve many problems. The purpose of writing this chapter is not written as a script wizard, but to provide you with several tools to help you automate tasks, without in-depth study of technical manuals or search site.
with MAXScript communication tool called “the Listener” (from the menu the MAXScript-> the MAXScript the Listener to open), it is an input window, we used to enter commands and executed immediately, while MAXScript also in which the display feedback. We enter the command line is displayed as black, the MAXScript feedback are shown in blue (indicating output values) and red (indicating the error message)
Let us start from these words

(Why the title “10 right? out of two is not the word, by the way about this article All symbols should be mentioned in the half-width input, which is not open to the state of Chinese input methods, such as the full stop is not a circle but)
now, here we go! !
dollar signs $ $ meaning that the currently selected object. For now, when we select only one object is best to use, because the slight difference of operating in a number of different objects. We use $ to do it? Well, the MAXScript one of the most commonly used function is to view and modify the properties of the objects are. To view the view the properties of the selected object, such format command. Properties, such as $. Radius is and $ height, respectively, View radius and height. (Radius is and the height so that the common words we should be very familiar with the parameters in the MAXScript are all based on English, we use the Chinese version is only the interface localization, so if a complete stranger, then the English word in the MAXScript still Sometimes, I think this is the official Chinese version of the the MAXScript no translation of the reason) – and the general rule in 3dsmax, the property also has its own hierarchy, that is an attribute which will contain its own between attributes, hierarchy separated by periods, such as input. material.diffusemap.coords.U_Tiling will query to the currently selected objects – diffuse map U repetitions. (That line of code can be translated into the Chinese:. Material diffuse reflectance map. Coordinates of U repeat, so we can see its word order is actually the same as the Chinese, it comes from a wide range of objectives, from the primary to the secondary … do not know the development MAXScript people how to think, anyway, I think quite accustomed to like the one above, enter an attribute name, that the Listener will only tell you the value of the property. If you want to modify it to a new value, use $ attribute = value format, such as $ length = 12.5. To modify the relative value, you can use the = – = * = / = above the current value of the addition, subtraction, for example, $ radius / = 6 divided by 6 the radius of the property for the current object (if it has a radius property). Tip: The Listener command input is best to use a small keyboard carriage return, because the small Enter command MAXScript immediately to the lines of code, while the large Enter in some cases waiting to enter more conditional statements.
the value of the equal sign does not necessarily have simple figures. We can use the other property values, a mathematical expression, or math at the top of the other attributes.
$, there is another similar usage: pick the name of the objects behind it, for example, enter $ Box01, tells MAXScript that we want the objects named Box01 using this format to apply the above mentioned property modification method is also applicable (such as $ box01.height). In addition, and in the Windows system like the use of wildcard characters * and?, For example, enter $ box *, equal to the specified name in the box at the beginning of all objects. (We will discuss in depth in the subsequent part of the knowledge of the operation of the multi-object.)
Tip: If the object name exists in a space, then their time would add the name ends mentioned in the MAXScript on the single quotation marks, for example, $ y box
Show “command
How can we know the name of an object with properties? Different objects with the attribute names may be far beyond our ability to remember, this is the show command comes in. It can be seen from the above example. show in the MAXScript Listener to show the name of the attribute list of an object. For example, selecting a box, enter the show $, you can see the Listener returned this information:
height: float
length: float
. lengthsegs: integer
. width: float
. widthsegs: integer
. mapCoords: boolean
heightsegs: the word of the integer
false
left of the colon is the attribute name, the term of the right of the colon that the desired value of the property type (at the end of that false MAXScript in hiccup , we did not hear well). If we try to give a wrong type of value for a property, such as of $ Sphere01.radius = true, that MAXScript will complain about the scarlet letter of a line of error message.
Tip: the meaning of the name of the commonly used value type integer: integer, a float: floating-point numbers (that is, allowed the decimal) the string: strings, numbers, outside with pairs of brackets, for example “hello world”, a boolean: true \ false value is also used to open and close, you can use true, false, the on, off point2: two-dimensional coordinates between the two numbers separated by commas, plus the square brackets, for example, [10, 20] point3: three-dimensional coordinates between the three digits, a comma separated, plus the square brackets, for example, [10,22,133] color: color RGB values, begin to color, plus three sets of values ??in parentheses denote the RGB values, separated by spaces, such as pure white (color 255 255 255) must be pointed out is not the object of all the properties will show command shows, in fact, to make the search results for “clarity, all the objects and the properties of specific types of objects, such as name, and the material and renderable, etc., are not displayed. At the same time, the modifier, material properties of the object is attached will not be displayed. If you need an absolutely complete and detailed list of attributes, you can go to the “General Node Properties” section (buried deep in the MAXScript Reference Manual, it is best to use the help system “index” function) in addition to the Properties, Methods., Operators, and The Literals entry records information on the type of object (see it, I said earlier, can not be separated from the reference manual is not a joke).
When the properties of an object secondary property, we can also show command to view the list of secondary attributes. For example, to view the material of a box, you can enter the show $ Box01.material If you want to see the bump map attribute list, according to the last command returns the list of attributes can be found in the properties of the bump map called bumpMap therefore input $ Box01.material.bumpmap the, and so on.
work
“double-word mode” Let us see now we can do something about it, every time just use the two words in the MAXScript, you able to do previously impossible things: in the scene to find and modify any property of any object, even if it is hidden, frozen or deep among the group.
quickly set any parameter of any object, including the use of an expression to set up replication of an object to another object.
by the object name to use wildcard characters (* and?), and one-time set up a bunch of objects of a certain property.
the role of two words, is not it? Now you have the vocabulary to see if we can distinguish between the role of the following single line of script:
$ Box01.height = $ Box02.height
$ Box01.height = $ Box01.length = $ Box01.width = 10
$ Sphere01.radius = $ Box01.height / 2
$ Box *. height = 10
< br /> $ Box *. isHidden = false
$ Omni *. multiplier / = 2
$ Box *. material = $ Sphere01.material
$ * Spot, Simplified Chinese translation came on = false
:
Box01 height is set with the the Box02 same

Box01 set the edge length of cube
10 the set Box01 height of half the radius of the Sphere01 (in other words, to make them as high)
scene all names in the Box at the beginning of the object height value is set to 10
cancel all name name beginning with Omni all the lights brightness Box at the beginning of the object hidden
the normal operation of the set to the original half

Box at the beginning of the object name to Spot at the beginning of the lights turn off the Sphere01 materials give all names (this example, the script does not reasons later explained in detail here only in order to make you understand MAXScript automatic operation of such tasks)
“move,” “rotate,” “scale,” and “in coordsys”
Now let us know the four verbs the MAXScript are used. For the first three move, rotate and scale, are already very familiar with (move, rotate, scale), we need only a little to explain their usage; for Coordsys, I think you can guess ( coordinate system).
move command, we want to give it the XYZ coordinate values, the coordinate values ??requires three values, separated by commas between them, outside the square brackets (the MAXScript value of this type is called point3), such as:
the move, $ Box01 [10,0,0]
the meaning of this line is the the Box01 axial movement along the X-10 units. Note that this is a relative displacement. If you want to move to the specified absolute coordinates, you actually modify the object location property position, in accordance with the said earlier, to modify the properties:
$ Box01.position = [10,0,0 ]
so will this Box 10,0,0 position on the world coordinates.
Here to talk about the rotate – rotate. Rotation values ??seem a little complicated a little bit, because it then the way to learn a word. In order to avoid using the extreme terror the tradition of true 3D rotation mathematical algorithms, the MAXScript eulerAngles rotation value input method; rotation X and Y rotation coupled with a Z rotation … and name similar to Euler XYZ Rotation Controller This rotation algorithm there is some flexibility and accuracy issues, but it strengths in ease of use make it worth using.
the rotate $ Box01 (eulerAngles 90 90 0)
above script is that the object along the X and Y axes rotated 90 degrees. (Note that the relative rotation)
Then you can talk about scaling. scale the same as the move is necessary to give a point3 value should be noted that the zoom value of 100% is 1, so if a 50% uniform scaling, the script is as follows:
$ Box01 scale [.5, .5, .5]
(the .5 is 0.5, in most of the computer digital input, if 0 before the decimal point can be omitted, write directly to point of access decimal places) the practice of the objects of different movements, we all know, by default they use the world coordinate system. If you want to use other coordinate system of local coordinates, the upper object coordinate labeled in front of our movement command in coordSys a coordinate system, such as the example in front of the first moving object changed: the in. coordSys local the move $ Box01 [ 10,0,0] This is the Box01 in the local coordinate Local moved 10 units.
“for” loop to automate
We understand the MAXScript in the most important automation tool – “for” loop, use the following format: for some variables in the operation of the list of objects that do need to do things in other words, each object listed in the list of objects being operated on an operation (or a series of operational processes. things you can do many commands combined). We mentioned at the beginning of the actual usage of the automation task. for i in selection do (i.wirecolor = color 0 128 0) In this example, some variable named i (variable names are arbitrary, only use the i in the loop count is the habit of Computer Programming) , the list of objects being manipulated in the keyword selection, you probably have guessed it means that the currently selected object collection, the so-called needs to be done is to set the object properties for a specified value, where the do is the object of the grid color “(ie, the default display of color in the non-material state) is set to green, translate it into Simplified Chinese is like this: for (each object) in (set) do ( set the grid color is green) looks very simple, right?
need to know is, every operation in the cycle, i for the operation object to object “placeholder”, to every object when automatic operation in the loop, i put the position to give the name of the object, which is equivalent to replace the $ or $ object.
the example above, use the selection to the specified operational objectives, and the practical application in many other cases, including the MAXScript preset keywords (objects, the geometry, lights, cameras, helpers in, shapes, systems , sceneMaterials, meditMaterials, and spacewarps), with wildcard name ($ Box, *), digital as well as specifically defined list of objects called arrays (fancy description). Now that we have for this tool, you can begin to truly automate tasks:
for i in $ * the Omni * do (i.multiplier = i.multiplier * 0.5)
< br /> all light levels with Omni words in the name of the script above will be reduced by half.
for i in selection do i.material = $ Box01.material
this line sucked all the selected objects given and the Box01 same material
< br /> We also can do behind the multiple command used together as long as they are outside the parentheses, separated by a semicolon between commands:
for i in the geometry do (i.motionblur = # image; i.motionBlurOn = ture)
This is quite open all the geometry in the scene motion blur and its mode set to image the way.
Hint: the script with MAXScript Macro Recorder macro recorder function, it is used to refer to on behalf of the currently selected object is $ common error in this $ is a single object representing the current selected, but when you select multiple objects you should use a selection key, so we need to clean out the worth repeating the script inside the $. Commonly used method is to put this script command from the macro recorder a selection loop for i in (that is, after the brackets do), and replace all the $ i to. (This comment referred to only when an error is encountered when using the macro recorder is easy to understand, and now can not get to the bottom, but it is a typical application of i) the “where” and “classOf
Now we to try a for loop. Write a one-line script to turn off all the lights in the scene:
for i in lights the do i.on = false
If, in our scenario any one of target point of light objects, you will see like the error message is returned in the Listener:
- Error occurred in the i loop
- Frame:
- i: $ Target: Spot01.Target @ [-11.212518, -15.219044,0.000000]
- Unknown property: “on” in $ Target: Spot01.Target @ [-11.212518, -15.219044,0.000000]
this information mean? Let us line by line translation:
script used for loop variable i is a problem.
If this is an animation, the animation frames:
When problems arise, i referred to in square brackets coordinates Spot01.Target to operate.
the problem itself – the object does not exist for the provision of “on” attribute.
In other words, our problem is due to the use of the keyword lights of said light this concept in light of the target objects are included in the operating object within, so MAXScript complain that the guy did not The switch can be set, and thus lay-off (if the number of lights in the scene you will find that some light is not turned off). To avoid this situation, we have excluded in operating a collection of objects in the target point of light, which is introduced in this section where the necessity of classOf where.
in a for loop, where we had a filter switch, before it can be in the loop runs every operation on an object property is “qualified” to judge. Judgment, the specified action is carried out, otherwise ignore the object. It can be abbreviated as follows:
for i in selection where (false) to do the operation
to false ie, “false”, ignore the operation of the object, when the following circumstances: < br />
for i in selection where (true) do the operation
perform operations on the target.
In actual use, we have to where followed by the one used to derive a true / false, true / false result of the expression, or to obtain the value of the Boolean type. In the expression we use the operator to true and false judgment. There are many ways on the two values. See the following table: operator = 1 == 1 true! Ranging from 1! True, = 2 1! = 1 false> greater than> 2 to false 2> 1 to true = large equal to 1> = 2 to false> = true 2> = 1 true <= less than or equal to 1 <= 2 to true 1 <= 1 to true = 1 false operator really judge the conditions of sample sample output and the two sides both for true false, and false false true and false, false true, and to true to true or one of them as "true" false or false false true or false, TRue to true or to true to true anti-judge (non-reversed) not true, to false not false, TRue not right conditions we do a few tests:
for i in $ Box, * the where (i.height> 10) do i.height the = 10
↑ to find out the name of the Box at the beginning and height is greater than 10 objects, its height is set to 10
for i in $ Box, * the where ((i.height> 9) and (i.height <11)) do i.height = 10
↑ to find out the name of the beginning of the Box and the height of the object between 9 and 11, their height is set to 10
for i in the geometry the where (i material == undefined) do i.isHidden = false
↑ cancel all the material does not give the geometry at hidden state
for i in the where shapes (i.baseobject.renderable == ture) do i.name = “RS_” i.name
↑ will be added before the name of all renderable spline curve “RS_” prefix (in order to select by name)
(the above example, it is necessary to practical, and can try to modify the operator and judgment conditions, the result is very interesting)
prompted the: above is an example mentioned, spline curve Spline objects renderable property use object.baseobject.renderable to access and modify (as well as necessary to prompt the practical application of an object to be replaced by object name or code i), it is also the common attributes of all objects. Also used a similar property is light objects castShadows property.
Well, now look back at the beginning of this section of the script error. We have (with lights) and many object to distinguish between those categories, so you want to use in the where function sentence which a judge category keywords each object: classOf
max are subordinate to a Class Category (Imagine the constellation or zodiac), the members of each category have some common parameters in accordance with the specific way of action. The box they belong to a category, and the sphere are also editable the mesh category has a significant difference. Now call out to our lovely Box01 to perform it:
classOf $ Box01
the MAXScript return value:
Box
and the show is similar, it can be used as a reference tool, but the former is used to query the attribute name, which used to query the category name. It show the biggest difference is that it can be used in expressions to do the true and false judgment computing:
classOf the the $ Box01 == Box
the MAXScript returns true. To this judge sentences where syntax, only for it with parentheses:
for i in the geometry the where (classOf i == Box) do i.height * = 2

↑ all the Box category of object height doubled, regardless of their name
before use classOf repair our lighting script, there is one thing to pay attention. If the box is coupled with a modifier, such as Bend bend, then:
classOf $ Box01 return the value became Editable_mesh instead of Box. Because the default case of the query to the current state of the object, rather than its original category (unless we will modify the device off). If you need to ignore to modify the original class of the results of the query object, do this: with the classOf $ Box01.baseobject at this time (equivalent to the query object baseobject attributes) the MAXScript will focus on the bottom of the object state to modify the stack to return the desired value a.
light closure of Positive Solutions
With where and classOf, now is the time to solve the problem of the lights in front of us script. At that time, we wrote the script is:
for i in lights do i.on = false
its operating results is encountered on properties of the target object and failed aborted. To correct this error, we have to do is to specify the command of the operation of the object to ignore the operation of the target point object. This technology, but a required course of batch lighting and camera! Free to establish several lights light in the scene, at least contains a lamp with a target point (of course, best get hold of the teapot look in the … related to open so see more)
in the view are free to choose a light target object input ClassOf $ Enter the Listener, you can see a category called Targetobject max return.
Now we can determine where the back fill in what to filter the objects of the target point.
entered in the Listener:
do i.on in. lights where (classOf i = targetObject) for i = false
Enter You can see all the lights off, the MAXScript relied on the
As a result, the real strength of the for loop script in our scene management fully apparent out. Have mastered the technology, we can modify the task that thousands of the specified object property a snap. Let me introduce my work highly frequent use of the simple statement:
cameras where (classOf i = targetObject) do for i in the i.mpassenabled = ture

↑ open at the same time all the camera multi-process effect
in the where the geometry (i.material == $ Box01.material) do for i i.isHidden = false
