AnyLogic - create objects dynamically on simulation time

Is it possible to dynamically create objects or modify them on run-time ?for example,on button click,another button created or change number of lines of a road? When I write this code for a button Action,in run-time 

road123.setBackwardLanesCount(3);

I get error below:

root: road123: Markup element is already initiated and cannot be modified.Please use constructor without arguments,perform setup and finally call initialize() .function

Solution

  • You'll get that error with any object you attempt to create at runtime using a parameterized constructor. If you create the object with a simple constructor (just "()") and then set all of the parameters individually, you won't run into that issue. Check the Anylogic API for specific information about the object you are using, because some require you to call .initiliaze() on that object after setting all of it's parameters if you created it using a simple constructor. Furthermore, if you want to add the object to the screen at runtime you'll need to add this code to the function that creates it:

    @Override
public void onDraw( Panel panel, Graphics2D graphics) {
    obj.drawModel(panel, graphics, true);
}

    where obj is replaced with the name of the object you created dynamically.
