Function: RemoveObjectTag

RemoveObjectTag ( OBJECT, TAG )

Removes a tag from an object.

Parameters

Parameter	Type	Description
OBJECT	OBJECT	The object to remove from.
TAG	VALUE(STRING)	The tag to remove.

Returns

Returns nothing. Cannot be used in expressions.

What It Does

This function removes a tag from an object. Removing a tag that is not assigned to the provided object does nothing.

Unlike names, tags are not sanitized on assignment to objects - they are added as-is.

Tags are matched case-insensitively.
