Add a group to another group by rupy-code

Andreas

Hi,

I would like to insert "Group1" into "Group2" by ruby-code.
What should I do to make this work?

Lets call them group1 and group2
They must be in the same 'context'.
You then use a newly made temporary group to contain both groups and manipulate all of the three groups as needed...

context = group1.parent ### e.g. 'model'
group_temp = context.entities.add_group(group1, group2)
### now transfer all group1's properties to group_temp
### you can skip those that are definitely not needed for YOUR groups...
group_temp.name = group1.name
group_temp.description = group1.description
group_temp.layer = group1.layer
group_temp.material = group1.material
group_temp.hidden = group1.hidden?
group_temp.visible = group1.visible?
group_temp.locked = group1.locked?
group_temp.casts_shadows = group1.casts_shadows?
group_temp.receives_shadows = group1.receives_shadows?
group_temp.glued_to = group1.glued_to
attrdicts=group1.attribute_dictionaries
attrdicts.each{|attrdict|
  name = attrdict.name
  attrdict.each_pair{|key,value|newMat.set_attribute(name,key,value)}
}if attrdicts
### Note; if 'group1' HAD "observers" you now need to add them to 'group_temp' too...
group1.explode
### this puts the 'group1.entities' at the correct 'level' in the new container.
### IF you want group2's entities 'loose', rather than as the group itself,
### then add 'group2.explode' too...
group1 = group_temp
### 'group1' now refers to the 'combined group'
### that now includes the original 'group1.entities' AND 'group2'...
### or 'group2.entities' if you exploded it too.

Are you talking about existing groups? If so, refer to TIGs post.

If you are creating new groups via Ruby:

group1 = model.active_entities.add_group group2 = group1.entities.add_group
