java - 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，一种类型的代理居住在另一种类型的代理中。尝试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);

代码已成功编译，但 anylogic 本身抛出错误:

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

问题出在这条线的内部，没有这条线，代理就会移动，但人口数量的参数保持不变:

this.goToPopulation(destinationCity.population);

将感谢任何帮助(可能您知道在更高级别的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:将目标人群放入 Main 的虚拟代理中(参见屏幕截图):

该错误应在 AnyLogic 8.3 或 8.4 中修复。
