Reference tags which can be positioned throughout the level.
|
|
These tags can later be refered to by the scripting system
|
|
so that their origins and angles can be referred to.
|
|
|
|
If you set angles on the tag, these will be retained.
|
|
|
|
If you target a ref_tag at an entity, that will set the ref_tag's
|
|
angles toward that entity.
|
|
|
|
If you set the ref_tag's ownername to the ownername of an entity,
|
|
it makes that entity is the owner of the ref_tag. This means
|
|
that the owner, and only the owner, may refer to that tag.
|
|
|
|
Tags may not have the same name as another tag with the same
|
|
owner. However, tags with different owners may have the same
|
|
name as one another. In this way, scripts can generically
|
|
refer to tags by name, and their owners will automatically
|
|
specifiy which tag is being referred to.
|
|

targetname - the name of this tag
