  Action commands
  Object tagging
 
1. Tags for sign and pictures objects
 
Some objects are "tagged". This means that they have been modelled with the ability of using a text or a picture command upon the object, instead of only applying a texture.
While modeling, you can "tag" objects in Accutrans or in Notepad (=in renderware text file) and create/make a picture-object or sign-object of the model.
 
 
2. Objects with tags
 
"Tag" Commands are used to change the texture of a certain part on an object. However, for this to work, these objects must be able to accept the tag command, which is built into the object when it is modeled.
che-kitchair01.rwx
create texture fabric1 tag=200
This is an example which we have seen when we spoke about transparency :
va2.rwx
create texture silvmetal mask=semitrans09 tag=200
For this tv-object , the tag number for the tv screen is 200
3. Objects with multiple tags
 
Some other objects have been modelled with several tags for different parts of the model. For those objects, you can use 2 or 3 texture commands for each part of the object. But all depends on how the model has been tagged . Tagged objects are rather rare , these are a few examples :
 
The brit-wall object set can be downloaded from the alusion-fr.com website or from the starheart website (http://www.sh3d-design.com/a5b.htm )and the set of models has been tagged in 3 parts : the front, the back and the wooden structure.
brit-ww2.rwx
Now we will add 3 new textures to the object : flat27 , flat35 en flat36.
create animate tag=100 me flat27. 1 1 1, texture flat36 tag=102 , picture flat35.jpg
Or you can and the textures roof4 , concrete en flat34.
create animate tag=102 me roof4. 1 1 99 , texture concrete tag=101 , picture flat34.jpg
Or another example :
create picture davegh0999.jpg, texture brit-plaster01 tag=101,
animate tag=100 me k-wooden1. 1 1 99
As you can see, there is only 1 texture command , and for the other 2 textures, we use 2 other commands : the animate command and the picture command.
The models have been tagged with 100 , 101 and 102. For the picture command, the texture has the .jpg extension, and you don't need to add the tag number.

Another popular building set is the win-wall set and has been modeled by Winnetou The models can be downloaded in the world Uberpath. Here we use 1 object :
win-wall01.rwx
On the picture you can see both sides of the orginal object (left side of the picture). Now we will change only the wallpaper side of the object : (middle of the picture).
create texture thwpaper3 tag=200
And now we will change only the brick side of the object (right side of the picture)
create texture thsiding2 tag=101
The inner side is tagged at 101 , the outer side is tagged with 200.
Now we make the 2 textures for both sides :
create texture thsiding2 tag=101, picture thwpaper3.jpg
As you can see, for the picture command, you need to add the extension .jpg, but you don't need to add tag=200.
In the standard object paths (Megapath, Uberpath), tagged objects are rather rare,because most of the models have not been tagged when they have been modeled. Certainly in the beginning of Activeworlds, objects have not been modeled with the intention of using an action command which can change 2 or more textures for 1 object
Searching for tagged objects is difficult, because there is no specific list or object yard with tagged objects. For wall objects for instance, you could search for double-sided walls. The prim objects are single sided, so there is no tagging for these. The homepage object walls (eg. fw-walplna1) are double sided but are not tagged, so you cannot apply another texture for 1 side of the wall.
Also outside the standard object path , the number of tagged objects is rare.
In the world Freebies, for only a few objects, it is mentioned that they can be tagged.
But most of the "che" objects accept tag=200

4. Avatar tags
 
Also avatars are tagged when you are modeling them. We already spoke about pickup-item movers http://www.venice3d.net/2015create35.html. , and then you had to add the correct avatar tag number. Every body part of the avatar has a specific tag number.
 
5. Modeling tags
 
When modeling, you also need to use specific tag numbers, used for building. And you add them in Accutrans or in Notepad , or another text editor.
For sign tags ( objects accepting text), we use tag number 100
For picture tags (objects accepting pictures) , we use tag number 200
You can apply 3 more textures in addition to the base texture : in the examples we have seen, these are the tags 101,102 and 200 (which is the picture tag).
These are the tag numbers you can use for building, other tag numbers cannot be used.
