THIS IS A STANDALONE PRODUCT! CasperVend is NOT required to use this product

CasperUpdate is a system which allows creators to make self-updating products. Once a product is sold to the customer, the product will check for an update every time it is rezzed (or at specific intervals). If an update is found, the customer is asked if they wish to receive the update (which will be delivered to them).

  • Completely web networked and automated.
  • No notecards to edit
  • Unintrusive - unlike competing systems, CasperUpdate allows customers to suppress further update notifications.
  • No-copy support - CasperUpdate can securely distribute updates for your no-copy products.
  • Efficient - Just a single script powers our DropBox (Compared to HippoUpdate's 28 script server).
  • Fast - Updates are delivered in a flash.
  • Unlimited number of products supported - Not "almost" limitless, *actually* limitless.
  • Any version format supported, including minor releases, code names and sub-versions.
  • Full statistics and reporting of updates delivered, including CSV export.
  • CasperVend integration - keep track of which products have been rezzed by the customer
  • Communications fully encrypted with SSL
  • A fully redundant, reliable network, as proven by the success of CasperVend itself
  • Free updates for life


In order to ensure that the service remains available and fast for everyone to use, we have a few limits and rules in place.

  1. The system must ONLY be used for its intended purpose - to provide product updates.
  2. Using the API commands for any other purpose is prohibited and is grounds for service suspension.
  3. Each object may only check for updates - at most - once per hour. Exceeding this limit temporarily (such as for testing purposes) is OK.
  4. The server "rate-limits" requests. See the below section for more information.

Rate Limits

The system will only process:

  1. 1 request per minute per user per product
  2. 5 requests per hour per object
  3. 50 requests per minute per IP address (region)
  4. 100 requests per minute per product
  5. 300 requests per minute per API key

If you are legitimately hitting these limits during normal usage, contact support and we'll look into getting them raised for you.

It is possible to temporarily exceed these limits, due to the nature of our network - for this reason, if you rez 100 objects at the same time, you may still get more than one dialog box.

Let's get started!

The steps you need to follow to get set up with CasperUpdate are as follows:

  1. Account and Product Listing Setup
  2. Adding CasperUpdate to Your Products
  3. Final Checks
  4. Add your items to your DropBox
  5. Test!

Video Tutorial

This video runs about 10 minutes, so settle in and make sure you don't miss anything.

If you don't want to - or can't - view the video, the text instructions begin below this section.

Please note that this video follows a slightly different process than the instructions on this page (Casper places the item into the dropbox BEFORE setting up CasperUpdate, and then replaces it later). Either method will work.

Account and Product Listing Setup

CasperUpdate uses the CasperVend back end for its functions, so you will still need a CasperVend website account (see the "Set up your account" section below). However, you do not need to own (or use) the vendors because CasperUpdate comes with its own DropBox.

If you have already set up your products in CasperVend, please skip down to the section for Adding CasperUpdate to Your Products.

New User? Set Up Your Account

If nothing happens when you click the shipping crate, or you don't get a popup menu when you click the dropbox, that means your current location does not allow you to run scripts.

If you don't get a "Go to URL" popup, you may have yourself muted - please check your viewer's mute/block list.
  1. Make sure you are on land where YOU can rez objects and run scripts. (Correct group tag, etc.)
  2. Rez the CasperUpdate shipping crate and click it to unpack. Do NOT open manually or your purchase will not properly register!
  3. Choose a suitable place inworld to leave your DropBox. This MUST STAY REZZED AT ALL TIMES so make sure it is someplace where it can stay long-term.
  4. Rez the DropBox. The DropBox will be named something like "CasperTech Dropbox ((version number))"
  5. Click the DropBox. This will bring up a popup menu.
  6. From the popup menu, select "Admin."
  7. This will show you a popup menu asking you to visit a URL. Click Go to URL.
  8. Once you have loaded the website, you may be asked to choose a password. Do this now. If you have previously created an account, you will be asked to enter your password and log in.
  9. If you don't remember your password, you will have a "forgot password" option as long as you arrived via a URL from inworld. (The inworld object acts as identity verification to the website.)
  10. Once successfully logged in, you should be presented with a page titled "Vendors", and you will see a few details about your DropBox.

Add Product Listings

  1. If you have closed the website, touch the DropBox again and choose "Admin"
  2. Follow the link it gives you.
  3. Once the site is open and you've logged in (if necessary), choose "Products" from the website's left side menu.
  4. Repeat the following steps for each product that you wish to use with CasperUpdate.
  5. Click "List New Product" at the top of the page.
  6. Fill out the information about your product.
  7. Most of the settings available to you here are only useful if you use CasperVend, or you plan to. You can ignore them all, except the following::
    • Item - This allows you to choose the item (from your dropbox) that you will deliver to your customers. If you're setting up a brand new product, choose "Don't deliver anything." for now, but remember to come back and select the dropbox item later.
    • Name - This is the name of the product.
    • Price - This isn't used by CasperUpdate, but it's required so that CasperVend merchants don't accidentally give their products away for free!
    • Permissions - The "Copy" tickbox is important. This changes the behaviour of CasperUpdate based on whether your item is copy or no-copy.
    • Version
  8. Click "Save" at the bottom of the product page.

If you are done adding product listings, then you can go to the next sections to get started with adding CasperUpdate to your physical products, checking the settings, and then putting the completed products in the DropBox.

Missing CasperUpdate options?

Not seeing the CasperUpdate options in your product listings?

That's because your purchase of CasperUpdate wasn't properly registered. You will need to rez your CasperUpdate shipping crate on land where YOU can run scripts and click it, in order for your copy of CasperUpdate to be registered to you.

If you've deleted your shipping crate, you can redeliver it from any CasperVend redelivery terminal.

Adding CasperUpdate to Your Products

Repeat the following steps for each product that you wish to use with CasperUpdate.

Make sure you use the correct script! DO NOT drag the
"CasperUpdate No-Copy Protector" script into your object yet!
Using the wrong script may destroy your object!
  1. Rez the product on the ground.
  2. Right click the product, go to "Edit", then switch to the "Contents" tab.
  3. Drag the "CasperUpdate vX.X" script into your object.
  4. Leave the object rezzed and continue with the following steps

Set Permissions

Make certain that you set the correct permissions for both your object and the script inside. Not doing so may result in people being able to obtain your products without paying.

For products with COPY permissions

  • Set "CasperUpdate vX.XX" script permissions to "No Modify" and "No Transfer".
  • Make sure your product object itself is set to "No Transfer".

For products with both COPY and TRANSFER permissions

  • Set "CasperUpdate vX.XX" script permissions to "No Modify" and "No Transfer".

For products with NO COPY permissions

For objects with NO COPY permissions, you MUST set:

  • Set "CasperUpdate vX.XX" script permissions to "No Copy" and "No Modify".
  • Make sure your product object itself is set to "No Copy"and "No Modify".

Adding no-copy protection to no-copy products

Once you have finished editing the script (as described above), and you have confirmed that the script is running, and you have taken a backup copy of your object, then - and ONLY then! - drop the "CasperUpdate No-Copy Protector" script into your object.


For no-copy objects, it is absolutely crucial that you set the product object to "no-modify", and that the "CasperUpdate No-Copy Protector" script stays copiable. If you don't do this, people will be able to effectively make copies of your no-copy item.

Edit Script and Set Options

Inside each of the products, you should now have (at least) a "CasperUpdate v#.##" script. Double click the script in order to open the script editor window.

  1. Add your API key

    On the website, click the "Overview" button around the top left of the page.

    In the "API Configuration" box, you should see a line which reads "Full API Key".

    Your full API key is a 40-character long code which will look something like this:


    Look for the following line:

    string APIKey = "";

    You need to place your key between the " characters. So, in this case, it will end up look like this:

    string APIKey = "1ff379c6a13eb414877b8734781244dbb594e56d";
  2. Add your Product Update Key

    You can find this key by going to the Products section on the website, clicking Edit next to the product you're currently working with, and scrolling down to "Update Key". Click the "Generate Key" button, and then copy the key into the script.

    In my case,

    string ProductUpdateKey = "";


    string ProductUpdateKey = "dd6ba159a09d3ceea613b5b7c80c01966557204b";
  3. Set the version

    The "Version" parameter should be set to the same version that you set on the product's entry in the website.

    For example,

    string Version = "";

    might become

    string Version = "1.0 BETA";
  4. Save the script

    Click "Save" at the bottom of the script. After a few seconds, you should see "Save complete" at the bottom of the window. If you see something else, check that you have made the edits exactly as described above.

    Make sure the "Running" tickbox at the bottom of the script is CHECKED/TICKED.

Final Checks

Once done, you should check that your settings are correct.

For objects with COPY permissions

  1. Your object should contain the "CasperUpdate v#.##" script, which should be set to "NO MODIFY", "COPY"
  2. If your object is no transfer, then the script should also be set to NO TRANSFER.
  3. The script should contain your API key, the Product Update Key, and the Version, and it should be saved and RUNNING (check the running tickbox at the bottom).

As an additional security feature, for all copiable products tracked through CasperVend only you may tick/check this additional option:

This will ensure that only the people who purchased your product will get the future updates.

As it shows in the picture, do NOT use this option if your product is transferrable, or if you normally sell through a medium that is NOT tracked by CasperVend.

For objects with NO COPY permissions

  1. Your object should contain the "CasperUpdate v#.##" script, which should be set to "NO MODIFY" and "NO COPY".
  2. The script should contain your API key, the Product Update Key, and the Version, and it should be saved and RUNNING (check the running tickbox at the bottom).
  3. Your object should be set to "NO MODIFY" and "NO COPY".
  4. Your object should contain the "CasperUpdate No-Copy Protector" script, which should be set to "NO MODIFY", "COPY", "TRANSFER".

Add your items to your dropbox

Do not drag over any items which show (no transfer) next to them. You cannot send/transfer those to your customers, so they will not work in the DropBox either.

Do NOT delete the DropBox script or your updates will not be sent.
  1. Switch back to Second Life, and right-click the dropbox that you rezzed out.
  2. Choose "Edit".
  3. Click the "Contents" tab in the edit floater. You should see a script with the name CasperTech DropBox".
  4. Drag the products (which you have set up with the CasperUpdate script) from your inventory to the DropBox contents window.
  5. Wait for the DropBox to upload information about the items to our servers.
  6. When finished, DropBox will show hovertext saying "Box is live" when this process is complete, along with the number of items it counts as valid (transferrable) items.
  7. If you chose 'Don't deliver anything.' when setting up your product, or if you replaced an item in the dropbox with a different name, you now need to go back to the website and edit the product you created, and select this item for delivery.


We recommend that you send a copy of the product to a trusted friend or alt. If set up correctly, they SHOULD NOT receive any notices from the CasperUpdate script, UNTIL you update your product.

You may wish to follow the steps below to test the update process to make sure everything works.

Remember that CasperUpdate will check - by default - on rez, and once per hour for each copy of the product. Update sending will be triggered if the version identifier has changed in any way from what is in the script.

About the update menu

  1. Not Now will wait until the next time a copy of the product is rezzed, and at least 1 hour from that time.
  2. Postpone will wait until the following version is released.
  3. Never will set a flag on the website, so that no matter how many copies are rezzed of that product, the customer never gets an update offer.

"Not Now" and "Postpone" answers are stored in the script - so if you delete the first copy and rez a second copy of the product with the CasperUpdate script, it will not know that you answered either of those two options before....and will ask you again.

As always, the customer may receive any future updates of copiable products at any time by visiting a redelivery terminal.

Additional functionality

Forced Updates

There are two options which can be used for forced (compulsory) updates. We highly recommend against forcing your users to update, since it will do nothing but annoy your customers.

In the case of combat systems and such, this kind of check should be done within the combat system protocol and NOT in the update script, for security reasons!

However, if you really want to do it, the two options available in the script are:

  1. Mandatory - This will continuously offer the customer updates until they accept it (once per minute).
  2. Automatic - This will automatically accept the update and deliver it to the customer, without any interaction.

Script interface

You can tell the update script to check for an update as follows (available in version 1.2 and above):

llMessageLinked( LINK_THIS, TRUE, "UPDCHK", NULL_KEY );

The "TRUE" parameter tells the script that it's a MANUAL check - so displays chat output. If this is a regular automatic check, you should pass in FALSE.

The script will also emit certain linked messages, so other scripts in the object can tell if there's an update:

//An update is available
llMessageLinked(LINK_SET, -9191, "UPDATE", "");

//An update has been requested
llMessageLinked(LINK_SET, -9191, "REQUESTED", "");

//You already have the latest version
llMessageLinked(LINK_SET, -9191, "NO_UPDATE", "");

//The user has not purchased this item
llMessageLinked(LINK_SET, -9191, "NO_PURCHASE", "");

//The object is being destroyed as part of an update(because it's no-copy)
llMessageLinked(LINK_SET, -9191, "DESTROYED", "");

Update Check Options

  1. UpdateCheckHours - This configures the script to check for updates at the interval specified (in hours).
  2. CheckOnLongTouch - (Version 1.2 and above) - If the user holds down the mouse on the object for longer than 2 seconds, the object will perform an update.

Debug Mode

The script will generally remain silent if no updates are found (unless the check is being done in a manual mode, such as after a long-touch event).

If there is no result message at all when an update should be sent, check for errors using debug mode:

  1. Temporarily change "integer Debug = FALSE" to "integer Debug = TRUE" in the script, in order to receive error messages
  2. Save, and then try again
  3. Watch for error messages

Updating Your Products

  1. Remove the old item from your DropBox, and wait for it to update.
  2. Add the updated version to your dropbox, and wait for it to update.
  3. Touch the DropBox, go to "Admin", and then follow the URL to take you to the website.
  4. Click "Products" on the left, and then click "edit" next to the product you are updating.
  5. Under "Item", you need to change the item to the new version (If the name hasn't changed, then leave as is.)
  6. Under "Version", give the product a new version number.
  7. Save the product.

Update Questions

Q. If a customer rezzes the an older version of a No-Copy product, will it delete the old version? Does it matter what sim/region the object is in?
A. Yes, it will delete the old version. The update is requested from the object that is being updated, so it doesn't matter what sim the object is in. Just make sure that it is configured PROPERLY before the product is first sold.
Q. If a customer buys two (or more) of a No-Copy product, and they trigger an update for each, will they get multiple updates or just one?
A. Each separate object makes its own request for an update. So if you have two (or more) products, they will each be able to update independently.

Sales Statistics

When a product is rezzed that contains the CasperUpdate script, the customer's purchase will turn green in your sales statistics:

In addition, any updates that are delivered will appear in your statistics with a notation for "Update" under the "Net" and "Received" columns. This can be seen in this example:

Exception: If YOU rez YOUR own product, it will not turn green. It only turns green when a different avatar rezzes the product. If you want to test this, you'll need an alt to rez the product in question with the update script.

Emergency: Renew / Revoke the API keys

If all goes well, you should never need to use these options.

However, in case one or more products with the the CasperUpdate script accidentally gets out with the script in a visible (modifiable) manner, you have the ability to revoke either the update key associated with that product from the product listing (which will prevent auto-updates for any copies already purchased), or renew the global API key associated with your account from the OVERVIEW tab (which will prevent auto-updates for ANY of your products already purchased).

Using either of these renew/revoke options means that, at minimum, the next update you send out for your product(s) (or all products if you change the global API key) must be sent manually after you replace the key information in the CasperUpdate script.

All customers will be able to redeliver copiable products at any time by visiting a redelivery terminal, regardless of whether you've had to revoke or renew the API keys.

Scripter Questions

Q. Can I use llSetScriptState to stop/not run the updater script as a means of making a scripted object use less memory?
A1. This won't actually give you any real benefit. The "script time" shown by the region is misleading - the script doesn't use any timers. If there are no pending events in the script, the script has zero performance penalty on the region, despite the 0.001ms figure given in the script panel. Basically, the script is inactive anyway.
A2. Yes, but don't reset the script (don't use llResetOtherScript). Instead, use llMessageLinked( LINK_THIS, TRUE, "UPDCHK", NULL_KEY ); to check for an update, once you've reactivated the script.
A3. Resetting the script will cause the script to forget the user's "Don't notify me" preferences.
A4. Resetting the script also makes you run the risk of exceeding our usage limits.
A5. Resetting the script will also reset the "firstContact" flag, which will interfere with the rez indication in the CasperVend statistics.
A6. Please don't reset the script. :)

FAQ / Troubleshooting

Q: "Sorry there was an error contacting the server. Please try again. If the error persists please contact customer support."
A:Enable "DEBUG" option in the script, and it will tell you the reason when you run it again.
