Question on copyvariable

Hi

I am trying to copy the exittrigger from one source to another using code.

This is what I used.

switch_selected(node("Source3", model()),1);

copyvariable(node("Source2", model()),node(">exittrigger", node("Source2", model())));

But an error appear "The variable that you specified does not exis on the highlighted object"

What does it mean and why this happen?

What is the right way of doing it?

Hi David,

This might be the code.You are not copying the variable to highlighted object but to itself.Other way to copy the variable into selected objects in the model is the command selectedobject() that gets the highlighted object.

switch_selected(node("Source3", model()),1);
copyvariable(node("Source3", model()),node(">exittrigger", node("Source2", model())));
or
copyvariable(selectedobject(ownerview(c)),node(">e xittrigger", node("Source2", model())));

First of all thanks for the reply. I have tried your suggestion. Unfortunately it did not work. what is ownerview(c)?

Hi David,

I am sorry selectedobject() does not gets the selected object(red bounding box) but the highlighted object(yellow bounding box) that won't work in this case.Ownerview() is the command that gets the topmost node of the view structure.In this code for source3 object I designate it as so().Please try the following code

  treenode object = so();
  switch_selected(object,1);
         {
  pt(getnodename(object));
  copyvariable(tonode(getnodename(object)),node(">exittrigger",node("Source2", model())));
         }

Once again thanks for your help. By placing the above code recommended in the Script window, I have selected Source 3 as so(). The error given is that "No object is currently highlighted". Is there a miss?

Just use createcopy:

createcopy(getvarnode(fromobj,varname),assertvaria ble(toobj,varname,1),1,0,0,1);

Thanks. It works.

But just wonder if there is some problem with this command and how it works? It is being used in the Edit Selected Object -> Copy from Highlighted. Don't quite understand.

There's no problem with the command - the second parameter is a node that contains the variable name as string data.

Jason

Possible for you to show me how to use copyvariable to copy the exittrigger from Source2 to Source3. Because I keep have the error saying the variable does not exist in the highlighted object.

Thanks

Hi David
We usually copy variables from highlighted object to selected object and the same we have to write in the form of code.The error we get because I have not set any highlighted object.The highlighted can be set by using the command setselectedobject() like switch_selected() for red selected objects .This highlighted object is accessed by the command selectedobject() and this command should be used in the first parameter of copyvariable.I was misunderstood the parameters of the copyvariable till yesterday.The two parameters of copyvariable belong to the same object that is highlighted and the variablenamenode are copied to selected object.But before using this copyvariable, we need to set the “selected” flag on the node.Thanks to Jason for suggesting createcopy() command that avoids writing redundant code.

I just tried a small model but not successful yet.In this model if the input of sink is greater than 49 I want this copy operation to take place between highlighted and selected object.Someone may be able to put me in right direction.

treenode item = parnode(1);
treenode current = ownerobject(c);
int port = parval(2);
treenode object1 = inobject(current,1);
treenode object2 = c;
if(getinput(current)>49)
{
setselectedobject(ownerview(c),object2);//highlight object    
switch_selected(object1,1);    
if(switch_selected(object1,-1));//check to see if it is selected
copyvariable(selectedobject(ownerview(c)),node(">entrytrigger",c));
deselectall();//Deselects all objects in the model
stop();
}

Hello David,

possibly you copied not the complete source code, but if it is your using code, you should write a slash "/" in front of the object name in the node-command.

Because of the missing slash the engine can't find the variable. And beware of this mistake, you have had in every node-reference.

switch_selected(node("/Source3", model()),1);

Jorge,

Thanks. I have tried. It did not has any difference. When you use the sampler, the node is given without the /. So I am unsure that is problem.

try out.

Thanks

If you're just copying from one known object to another and not using a selection set, then why are you interested in finding the highlighted, selecting the target and using the command that is purposed for the GUI interface?

If it's for ease of reading your code, create a user command: copyVariable(<fromobj>, <toobj>,<variablename>)

treenode fromobj=parval(1);
treenode toobj=parval(2);
string varname=parstr(3);
createcopy(getvarnode(fromobj,varname),assertvaria ble(toobj,varname,1),1,0,0,1);

Sagar,

thanks. I kept having an error on the command ownerview(c). Try to run your model with out the "if" requirement. Check if you have the error too.

David

Hi David,

Probably it has to do something with the VIEW tree to get the path of the trigger in the first parameter of setselectedobject().Btw you no longer require slash before the object name in Flexsim 7.See this Post

Hello Sagar,

I think it has more to do with getting an object highlighted by command [yellow frame]. Selecting an object works [red frame], but how to write a source code wherein the simple procedure is implemented clicking with the mouse pointer on an object.

Hi all,

If we use activedocumentnode() command as parameter 1 in the setselectedobject command, the second parameter, which is an object will be yellow highlighted.

treenode acc = activedocumentnode();
setselectedobject(acc,current);

In the attached model, the setselectedobject command is selecting the object which is the 2nd parameter. Moreover, the owner view of the object going to be selected is the perspective view. So when I use activedocumentnode(), it returns a reference to the perspective view, which is the active document node. If I am wrong anywhere, please correct me.

Hi Jorg,

Absolutely!In the midway of solving this problem after going through some relevant commands I realized that these commands are more for developers than for regular users like getting the node associated with the window.I am happy that i have learnt few commands.
@Arun:Thanks,that’s the right command.Somemore information while using this command activedocumentnode()
