【问题描述】：

在我的 AnyLogic 模型中，Container 代理在 Main 代理中移动到不同的位置。

Main 在特定位置包含多个 Block 代理实例。 Block 包含一个多桥桥式起重机，它应该拿起 Container 并将其移动到本地存储。

当 Container 被放置在 Block 的起重机范围内的 Attractor 上时，Block 内的进程被调用。此过程包含 Entry、MoveByCrane 和 Exit 块。在 MoveByCrane 块中，在抓住步骤中，AnyLogic 给了我以下错误：

所有的 Block 代理都位于 main 中的不同坐标。他们每个人都有自己的坐标参考/原点。（block中的位置（0,0）与main中的（0,0）不同。）这是错误信息中“空格”一词的含义吗？

有没有办法将代理从一个空间移动到另一个空间？

我应该从一个空间移除（下沉）代理并在另一个空间中创建一个新的吗？

【解决方案1】：

是的。

最简单的方法是使用Main 中的Enter 和Exit 块以及您的代理类型并以这种方式将代理发送到不同的空间。在Enter 属性中，指定代理类型中的位置，它将使您到达的代理“切换”到新空间。

如果您不使用流程建模块，则需要调用 setEnvironment()，然后使用 setLocation(...) 在其新环境中定义代理位置
