尝试在分层模型中移动代理时出现 AnyLogic 错误

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另一种中。为了在更高阶的代理之间移动代理，我使用了以下代码（找到随机连接的代理，然后尝试增加其数量，然后定义内部位置）：

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

代码编译成功，但是anylogic本身抛出错误：

java.lang.RuntimeException: root.cities[0].population[40]:

问题出在这条线里面，没有这条线agent在移动，但是population number的参数不变：

this.goToPopulation(destinationCity.population);

将不胜感激（可能您知道在高阶代理之间移动代理的不同方式）！

Answer 1

这是 AnyLogic 8.0-8.2 的一个错误。 AFAIK，如果目标人口位于 Main，则会出现错误。有一个解决方法：将目标人群放在 Main 的虚拟代理中（见屏幕截图）：

该错误应在 AnyLogic 8.3 或 8.4 中修复。
