世界节点

A set of world nodes:一组世界节点：

•   World Trigger — a cuboid-shaped node, which fires callbacks when any node (collider or not) gets inside or outside of it.   World Trigger —一个长方体形的节点，当任何节点（是否有碰撞体）进入其内部或外部时，都会触发回调。
•   World Clutter — a node used to manage a great number of node references, baked as one object. Objects are scattered, scaled and oriented randomly, they cannot be managed manually.   World Clutter —一个用于管理大量节点引用的节点，作为一个对象烘焙。 Object是s散布，缩放和随机定向的，they无法手动管理。
•   Switcher — a cuboid-shaped node, switching off (or turning on) all of the nodes inside of it immediately. Switcher should be a parent node for the nodes it controls.   Switcher —一个长方体形的节点，立即关闭（或打开）其内部的所有节点。 Switcher应该是它控制的节点的父节点。
•   Occluder — a node used to cull objects that are not seen behind it.   Occluder —一个节点，用于剔除后面看不到的对象。
•   Transform — a succession of transformations based on an arbitrary path.   Transform —基于任意路径的一系列转换。
•   World Expression — a cuboid-shaped node, inside of which arbitrary expressions are executed. These expressions can be executed for children nodes of World Expression as well.   World Expression —一个长方体形的节点，在其中执行任意表达式。这些表达式也可以对World Expression的子节点执行。
•   World Spline Graph — a node used to place various nodes at points and along the segments (linear or curved) of a spline graph. It can be utilized to create roads, pipelines, etc.   World Spline Graph —一个节点，用于在样条图的点处以及沿线段（线性或弯曲）放置各种节点。可用于创建道路，管道等。
