Examples

<lsl>// UnSit on Sit, Using a sit target default {

   state_entry()
   {
       llSitTarget(<0.0, 0.0, 0.1>, ZERO_ROTATION); // Needed for llAvatarOnSitTarget to work. The vectors components must not all be set to 0.0
   }
   changed(integer change) // Triggered when various changes are sensed.
   {
       if(change & CHANGED_LINK) // When an agent sits on an object they become a new link.
       {
           key user = llAvatarOnSitTarget(); // Store the UUID of any agent sitting on the sit target.
           if(user) // An avatar is on the sit target.
               llUnSit(user); // Un-Sit the avatar.
       }
   }

}</lsl> <lsl>// UnSit on Sit, NOT using a sit target

default {

   changed(integer change) // Triggered when various changes are sensed.
   {
       if(change & CHANGED_LINK) // When an agent sits on an object they become a new link.
       {
           integer links = 0; // Create an integer type variable.
           if(llGetObjectPrimCount(llGetKey()) < (links = llGetNumberOfPrims())) // During the check store the number of links.
           // If the number of prims is fewer than the number of links, the last must be an avatar.
               llUnSit(llGetLinkKey(links)); // Use the key of the last link to be added (the avatar) to call llUnSit().
           else
               llOwnerSay("Some kind of linking or unlinking has changed me but, I am not being sat on.");
           // llUnSit() triggers the changed event too (the number of links is reduced by 1).
       }
   }
