实验性实验性可选origin: Vector3一个可选的世界空间原点，用于将复合体积居中。 若未指定，原点将设置为(0,0,0)
An optional world space origin on which to center the compound volume. If not specified, the origin is set to (0,0,0)
实验性获取复合方块体积的方块位置迭代器。此迭代器将允许创建者遍历较大边界区域内的所有选定体积。 被减法体积覆盖的区域将不包含在迭代器步骤中。 （即，若你将一个立方体推入堆栈，然后在同一位置推入一个减法体积，那么迭代器将跳过初始体积，因为它被认为是负空间） 请注意，此迭代器返回的方块位置是绝对世界空间（无论推送的复合体积项是绝对的还是相对的）
Fetch a Block Location Iterator for the Compound Block Volume. This iterator will allow a creator to iterate across all of the selected volumes within the larger bounding area. Areas of a volume which have been overridden by a subtractive volume will not be included in the iterator step. (i.e. if you push a cube to the stack, and then push a subtractive volume to the same location, then the iterator will step over the initial volume because it is considered negative space) Note that the Block Locations returned by this iterator are in absolute world space (irrespective of whether the compound volume items pushed are absolute or relative)
无法在只读模式下调用此函数，详见 WorldBeforeEvents。
实验性获取表示堆栈中所有体积的容器的最大边界框 请注意，返回的边界框在绝对世界空间中表示（无论推送的复合体积项是绝对的还是相对的）
Get the largest bounding box that represents a container for all of the volumes on the stack Note that the bounding box returned is represented in absolute world space (irrespective of whether the compound volume items pushed are absolute or relative)
无法在只读模式下调用此函数，详见 WorldBeforeEvents。
实验性获取表示堆栈中体积的最外边界矩形的最大方块位置。 请注意，返回的最大位置在绝对世界空间中（无论推送的复合体积项是绝对的还是相对的）
Get the max block location of the outermost bounding rectangle which represents the volumes on the stack. Note that the max location returned is in absolute world space (irrespective of whether the compound volume items pushed are absolute or relative)
无法在只读模式下调用此函数，详见 WorldBeforeEvents。
实验性获取表示堆栈中体积的最外边界矩形的最小方块位置。 请注意，返回的最小位置在绝对世界空间中（无论推送的复合体积项是绝对的还是相对的）
Get the min block location of the outermost bounding rectangle which represents the volumes on the stack. Note that the min location returned is in absolute world space (irrespective of whether the compound volume items pushed are absolute or relative)
无法在只读模式下调用此函数，详见 WorldBeforeEvents。
实验性获取复合体积的世界空间原点
Fetch the origin in world space of the compound volume
无法在只读模式下调用此函数，详见 WorldBeforeEvents。
实验性返回一个布尔值，表示是否有任何体积项推送到体积中
Return a boolean which signals if there are any volume items pushed to the volume
无法在只读模式下调用此函数，详见 WorldBeforeEvents。
实验性返回一个布尔值，表示给定的绝对世界空间方块位置是否在一个正方块体积内。 例如，若堆栈包含一个大立方体，然后是一个稍小的负立方体，并且测试位置在负立方体内 - 函数将返回false，因为它不在“体积”内部（它在边界矩形内，但不在正定义的位置内）
Return a boolean representing whether or not a given absolute world space block location is inside a positive block volume. E.g. if the stack contains a large cube followed by a slightly smaller negative cube, and the test location is within the negative cube - the function will return false because it's not 'inside' a volume (it IS inside the bounding rectangle, but it is not inside a positively defined location)
无法在只读模式下调用此函数，详见 WorldBeforeEvents。
实验性可选forceRelativity: CompoundBlockVolumePositionRelativity决定函数返回的CompoundBlockVolumeItem是强制为相对坐标系还是绝对坐标系。
true = 强制返回的项相对于体积原点
false = 强制返回的项为绝对世界空间位置
Determine whether the function returns a
CompoundBlockVolumeItem which is forced into either relative
or absolute coordinate system.
true = force returned item to be relative to volume origin
false = force returned item to be absolute world space
location
若未指定标志，返回的项将保留其推送时的相对性
If no flag is specified, the item returned retains whatever relativity it had when it was pushed
若堆栈为空，则返回undefined
Returns undefined if the stack is empty
检查最后一个推送到体积堆栈的项，而不影响堆栈内容。
Inspect the last entry pushed to the volume stack without affecting the stack contents.
无法在只读模式下调用此函数，详见 WorldBeforeEvents。
实验性从体积堆栈中移除最后一个条目。这将使堆栈大小减少一个
Remove the last entry from the volume stack. This will reduce the stack size by one
无法在只读模式下调用此函数，详见 WorldBeforeEvents。
实验性要推送到堆栈末尾的项
Item to push to the end of the stack
向堆栈推送一个体积项。体积项包含一个“动作”参数，决定这个体积是正空间还是负空间。
该项还包含一个locationRelativity，决定它是相对于复合体积原点的还是绝对的
Push a volume item to the stack. The volume item contains
an 'action' parameter which determines whether this volume
is a positive or negative space.
The item also contains a locationRelativity which
determines whether it is relative or absolute to the
compound volume origin
无法在只读模式下调用此函数，详见 WorldBeforeEvents。
实验性要添加或替换的项
Item to add or replace
若体积堆栈为空，此函数将推送指定项到堆栈。若体积堆栈不为空，此函数将用新项替换堆栈中的最后一项。
If the volume stack is empty, this function will push the specified item to the stack. If the volume stack is NOT empty, this function will replace the last item on the stack with the new item.
无法在只读模式下调用此函数，详见 WorldBeforeEvents。
实验性可选preserveExistingVolumes: boolean此可选布尔标志决定相对的CompoundBlockVolumeItem是冻结在原地，还是受新原点影响。
想象一个场景，你在原点周围有一系列相对位置，组成一个球体；所有这些位置范围都在-2到2之间。
将每个位置作为相对项推送到复合体积中。
现在，移动原点，代表球体的所有位置都会相应移动。
但是，假设你想在第一个球体旁边添加第二个球体。
在这种情况下，设置新原点到几个位置之外，但preserveExistingVolumes = true。
这将设置一个新原点，但现有的球体位置将保持相对于原始原点。
现在，你可以再次推送相对球体位置（这次它们将相对于新原点）- 结果是两个球体彼此相邻。
This optional boolean flag determines whether the relative
CompoundBlockVolumeItem's are frozen in place, or are
affected by the new origin.
Imagine a scenario where you have a series of relative
locations around an origin which make up a sphere; all of
these locations are in the range of -2 to 2.
Push each of these locations to the compound volume as
relative items.
Now, move the origin and all of the locations representing
the sphere move accordingly.
However, let's say you want to add a 2nd sphere next to the
1st.
In this case, set the new origin a few locations over, but
'preserveExistingVolumes' = true.
This will set a new origin, but the existing sphere
locations will remain relative to the original origin.
Now, you can push the relative sphere locations again (this
time they will be relative to the new origin) - resulting in
2 spheres next to each other.
将复合体积的原点设置为绝对世界空间位置
Set the origin of the compound volume to an absolute world space location
无法在只读模式下调用此函数，详见 WorldBeforeEvents。
实验性可选preserveExistingVolumes: boolean参见CompoundBlockVolume.setOrigin的参数描述
See the description for the arguments to CompoundBlockVolume.setOrigin
类似于CompoundBlockVolume.setOrigin - 此函数将通过给定的增量将原点平移到新位置
Similar to CompoundBlockVolume.setOrigin - this function will translate the origin by a given delta to a new position
无法在只读模式下调用此函数，详见 WorldBeforeEvents。
表示复合方块体积，它是由多个单独的方块体积定义组成的集合，作为一个集合，定义了一个较大的（有时是不相邻的）不规则形状的体积。 这个类松散地基于CSG（计算实体几何）的概念，允许用户通过构建体积和空隙的堆栈来创建复杂的体积，从而形成一个更大的单一体积。 例如，通常情况下，创建者会通过为每个面创建6个“墙”面来创建一个空心立方体。 使用复合方块体积，创建者可以通过创建一个单一的外部实心立方体，然后在较大的立方体内定义一个单一的“空”立方体来定义一个空心立方体。 类似地，复合方块体积可以表示不规则形状的体积（例如，一棵树由一个树干和许多不一定连续放置的叶子立方体组成）。 添加到复合方块体积中的每个体积（默认情况下）相对于设置的原点（无论是在构造时还是通过某个设置函数）都是相对的。 但是，也可以将绝对性质的体积推送到复合集合中，这些体积不受原点变化的影响。
The Compound Block Volume is a collection of individual block volume definitions which, as a collection, define a larger volume of (sometimes non-contiguous) irregular shapes. This class is loosely based on the concept of CSG (Computational Solid Geometry) and allows a user to create complex volumes by building a stack of volumes and voids to make a larger single volume. For example - normally a creator would create a hollow cube by creating 6 "wall" surfaces for each face. With a Compound Block Volume, a creator can define a hollow cube by creating a single outer solid cube, and then defining a further single 'void' cube inside the larger one. Similarly, the Compound Block Volume can represent irregular shaped volumes (e.g. a tree consists of a trunk and lots of leaf cubes which are not necessarily contiguously placed). Each of the volumes added to the CompoundBlockVolume are (by default) relative to the origin set (either at construction or via one of the set functions). However, it is also possible to push volumes to the compound collection which are absolute in nature and are not affected by origin changes.
