Change Group members with code during simulation

[ FlexSim 20.2.3 ]

Hello,
I am trying to change the members of a location group with code but during a simulation run. With our first tests, it seems that the group content is updated on reset, also when wu use group.addmember()

Is it possible to change the location members of a group during a simulation run ? If yes, how ?

Group("Locations").addMember(myobject) 

works but you also need to push to the Locations global List:

List("Locations").push(myobject);

Thank you @Jason Lightfoot for your answer.

Actually I made a mistake when I defined myobject. I used Object instead of treenode.

Then with treenode definition it worked but it did not work when I tried pushing to the list. Maybe because the object was already in another group and hence already in the Locations global List ?

It shouldn't make a difference whether you put an object variable or treenode to the list - if the list has unique values checked it will only have one list entry, even if you push it twice.

Hi again @Jason Lightfoot ,

I am working with multilocations dynamicaly added or removed with flexscript. Sometimes I have strange behaviors and although I do as you told me I was wondering if you could explain why the entries have to be changed in both the Group("groupName") and the global List("Locations") ? Maybe this is different with Multilocations ?

I use Group.removemember() and List.pull() / Group.addmember() and List.push().

Attached you can find an example where I could not make it work. After 50s chairs one should be removed from the group. After 100s they should be back and available for seating.

Hello @Sebastien,

Would it work to use a time table to add or remove members?

I added the sublocations (individual chairs) of the multilocation chairs 1 to the time table. This can be done when you select the multilocation and in the properties panel under the Multilocation tab select the Edit Mode. This will allow you to select the individual members of the group.

I then set a label on each chair called available and set it to 1. This label will be used in the location list to decide if a patient can pull it or not, so it needs to be added to the list and resource filter.

Thank you @Jeanette F for your answer.

It helped me to figure out why I had my issue. I was actually not taking the sublocations into account when I was pulling or pushing them to the list.

Sor for anyone looking for an answer for multilocations the code should look like this:

Group("Locations").addMember(multilocation);

for(int i=1; i<= subLocations.length; i++){
    List("Locations").push(subLocations);
}

Best regards,
