QW 3D Object Vendor

QW 3D Object Vendor is a low prim object vendor. The vendor itself exists of just 2 prims for the construction plus 1 prim that serves as the demo object and there will be displayed only 1 object for sale at the time. That makes that there are only 4 prims in use for showing an unlimited amount of 1 prim objects.

It's possible to pause the show and to scroll backward and forward by clicking somewhere on the vendor. The symbols "<", "||" and ">" on the vendor serve as reminder for this.

The vendor also shows the name of the shop and the name of the product. Furthermore it indicates that at the left side is the demo object and that the object for sale can be found at the righthand.

QW Internet Radio Tuner Elite

[not yet available]

Now i'm working on QW Internet Radio Tuner Elite.

The main dialog box shows 12 main genres.

The buttons on the main dialog box give access to 12 sub dialog boxes.

On every sub dialog 11 radio stations can be activated (one at the time of course).

This gives accces to 12 x 11 = 132 radio stations.

The last button on every sub dialog box links back to the main dialog box.

2 Notecards initialize the script. Notecard 1 initializes the main dialog box, notecard 2 initializes all radiostation on the sub dialog boxes. Owners are allowed to edit both notecards and when all gets a mess the creator can be asked to clean up things :-)

The script will remember the last current dialog box. This makes it easier to select the next station within the same main genre without walking thru the top level every time.

QW Visitor Detector

QW Visitor Detector builds a list of unique visitor names and informs the owner about this.

When the list exceeds maximum length AND every 24 hours an Instant Message and an Email are sent to the owner of the script (guess who?) and the list is cleared.

The script checks for visitors every x seconds (5 atm) and adds only visitors to the list who are not already listed. With the time slice of x seconds it's possible that a visitor who stays a shorter amount of time (average shorter than x/2 seconds) will not be added to the list. This can hardly be problem.

Pros and Cons of Instant Message: The delay of an Instant Message is 2 seconds. This fits pretty well in the time slice of x seconds of the sensor's repeat interval. The maximum length of an Instant Message is only 1024 bytes. This has a big impact on the length of the visitors list. If the average length of resident names is 20 bytes then 1024 / 20 = 51 names can be added to the list without the need for multiple IM's to present the names.

Pros and Cons of Email: The delay of an Email is 20 seconds. This is much more than the time slice of x seconds of the sensor's repeat interval. This may cause that some visitors will not be add to the list. The length of Email messages is not limited. So only free memory impacts the length of the visitors list. When the scipt starts and the visitors list is still empty there are about 15000 bytes free. When the list grows and grows the Email work space will grow too. At the moment the Email is generated there it wil take about the same length as the visitors list. Thus 15000 bytes minus 1000 bytes overhead makes 14000 bytes left for the visitors list AND email work space. This limits the visitors list to a maximum length of 14000 / 2 = 7000 bytes. Using the same average name length as mentioned above then 7000 / 20 = 350 names can be added to the list without generating a Stack-Heap Collision error. A major Pro of Email is that the information will be time stamped and saved outside Second Life.

As long both - Instant Message AND Email - are used the visitors list is limited to 51.

Final remarks:

• The owner of the script will not be added to the visitors list;
• On my tiny land the sensor range is 50 meters full sphere (arc=PI);
• Only visitors Over My Land will be added to the list.
