Tag

Tags are labels that characterize Objects. These tags act as metadata which can later be used to identify those Objects with a specified tag. They are managed in the Attribute Editor, where they can be created, deleted, and edited. Further changes can be done in the Logic using the Tag Nodes.

The purpose of tags is to group Objects under a label. For example, several Objects sharing certain property can be grouped under a common tag, this allows for easy filtering in case Objects with this property are needed. Furthermore, tags give the user complete freedom as any set of Objects can share a tag and Objects can have several tags.

Two Example Tags.

Here, the Object has two tags called a_tag and another_tag.

Create

To create tags, the user simply needs to locate the Tag Attribute towards the bottom of the Attribute Editor, while the desired Object is selected. There, one simply needs to add an Element by clicking the plus icon. As seen in the example above, it is possible for one Object to have multiple tags. Similarly, it is possible for multiple Objects to share the same tag(s).

Creating Tags.

Delete

To delete a tag, the user only needs to click the remove icon to the right of the tag.

Deleting Tags.

Tag Nodes

There are several Nodes that deal with tags. These are:

• Add Tag, which adds a tag to an Object.

• Get Objects By Tag, which gives all Objects that share a specified tag.

• Remove Tag, which removes a tag from an Object.

It is important to note that tags added with the Nodes are treated separately from tags added in the Attributes. This is because the tag is only added once executed in the Incari Player and does not interact in any way with the tags added in the Atribute Editor. So if a tag is added by a Node, it will not appear under the Tag Attribute.
