[QUOTE=Destroy666;201895]2. I though about func_static and func_group, but not sure what’s next.
Alertentity, setstate or what?[/QUOTE]
Using a func_group is useless, because:
A func_Group is en entity wich only counts for radiant, only for user convenience, and it is converted to a normal brush on compile, it’s mostly used for big terrains …
Func_group information
So a func_static will still help you.
func_static information
ANd, good, you should indeed use setstate. Because i don’t know your exect purpose i’m gonna give an example:
Make a brush, select it and make it into a func_static with scriptname “save” for this example.
gold
{
stolen
{
setstate save default // This will set a entity with the scriptname "save" visible
}
}
I hope this is clear enough, if not, ask further

Edit
Indeed CyburK, it needs to be default 
Thanks for corecting my fast made scipt:p
setstate <targetname> <default|invisible|underconstruction>
Sets the state of an entity.
