worldspawn is a point entity available in all 
Source games.它 (或者“the world”) 是存储地图的非交互式部分以及一些全局配置选项的单个实体。它包括：
其他的一些注释：
- 一个地图中只能存在一个。(由于 Hammer 不允许直接创建
worldspawn，因此很难打破此规则。)另外，通过地图属性选择世界后，请勿克隆世界的任何部分。这将复制worldspawn实体，导致崩溃。但是，在此之后取消选择和取消选择后的克隆将正常运行。 - 环境破坏和自杀通常归咎于世界实体。
- 约束器可以通过不为其作用目标实体指定名称来把作用分配给 worldspawn。
