adding a node to a group

I'm trying generate a number of BasicFR's whit conveyors with the GUI.

After copping all the containers I want some items in one groep, so they can easily be selected.

I'm using this code to create a new group an ad a new node in the group. Al I need to do is put the right info in the node. When I get my test running i can use the code while generate(ing) the conveyors.

// Create a new group
treenode Groups = node("/Tools/Groups",model());
nodeinsertinto(Groups);
setname(last(Groups),"Invisible");

// create a new node
treenode GroupWhithInvisible = last(Groups);
nodeinsertinto(GroupWhithInvisible);
nodeadddata(last(GroupWhithInvisible),DATATYPE_NUM BER);

//putting the right info in
setnodenum(last(GroupWhithInvisible),tonum(current ));


If I use the code as above than it results in the number 426970840
If I ad the item to a group with the standard group function it results in 426163248

Wat is the right way to do this?

thanks

Frank,

Groups are not made with the tonum() command because the values from the tonum command may not be valid after a compile or a reload. Instead they use couplings which are what the port connections use. Couplings create a number value that will remain valid until it is deleted and they will also be a little easier for you to use.

When you use couplings you need to remember:
1. The createcoupling() command will create a node in each container specified when you call the command.
2. When you destroy one of the coupling nodes it will automatically destroy the other coupling node.

To create your own group you will need to:
1. Make sure that there is a Groups node in the Tools node in the model. Usually this is not created in a model until the first group is created.
2. Make sure that there is a Groups node in each object that you want to be in a group. To insert the correct node and set the name of the node for the object myobject try: nodeinstertafter(node("/myobject>LAST", model())); setname(node("/myobject>LAST", model(), "Groups");
3. The create coupling command in your code would look like: createcoupling(Groups, node("/myobject>Groups", model());

I hope this helps,
Brandon

Thanks Brandon.

It finally works. createcoupling was the magic function.

This is what the code looks like:


treenode Focus = node("@>objectfocus+",c);

//Group in the model
treenode Groups = node("/Tools/Groups",model());
nodeinsertinto(Groups);
setname(last(Groups),"GENEREER");
treenode GroupWhithInvisible = last(Groups);

int AantalItems = gettablerows(Focus);

for ( int a = 2; a<= AantalItems; a++)
{
// Group in the Item
treenode Current = rank(Focus,a);
treenode GroupItem = node(">Groups",Current);
nodeinsertinto(GroupItem);
setname(last(GroupItem),"GROUP");
treenode GroupOfItem = last(GroupItem);
createcoupling(GroupWhithInvisible,GroupOfItem);
}
