尝试在分层模型

Question

任务描述：模型包含两种类型的代理，一种类型的代理生活在其他代理中。试图在更高级别的代理之间移动代理，我使用以下代码（找到随机连接代理，然后尝试增加其数量，然后在内部定义位置）：

City destinationCity = (City) city.getRandomConnectedAgent();
this.goToPopulation(destinationCity.population);
double newX = uniform(-50, 50);
double newY = uniform(-50, 50);
this.setXY(newX, newY);

代码已成功编译，但anylogic本身会抛出错误：

java.lang.RuntimeException: root.cities[0].population[40]:
INTERNAL ERROR: moving shape from one owner directly to another: com.anylogic.engine.presentation.ShapeEmbeddedObjectPresentation@566dc332 -> com.anylogic.engine.presentation.ShapeEmbeddedObjectPresentation@f8b9090

问题在于这条线，没有这条线代理正在移动，但是人口数的参数保持不变：

this.goToPopulation(destinationCity.population);

非常感谢任何帮助（可能你知道在更高级别的代理商之间移动代理的不同方式）！

Answer 1

这是AnyLogic 8.0-8.2的错误。 AFAIK，如果目标人口位于Main，则会出现错误。有解决方法：将目标人口放在Main的虚拟代理中（见截图）：

应该在AnyLogic 8.3或8.4中修复该错误。
