Summary
Function: key llRequestInventoryData( string name );156 | Function ID |
1.0 | Forced Delay |
10.0 | Energy |
Requests data from objects inventory object. When data is available the dataserver event will be raised.
Returns a key that is used to identify the dataserver event when it is raised.
• string | name | – | an item in the inventory of the prim this script is in |
name Type | dataserver | Description | ||||
---|---|---|---|---|---|---|
Landmark | (vector) | The vector data received by dataserver is a global position as an offset from the current region's origin (<0,0,0>). To obtain the absolute global position of a landmark, add llGetRegionCorner() to the vector. |
Caveats
- This function causes the script to sleep for 1.0 seconds.
- If name is missing from the prim's inventory then an error is shouted on DEBUG_CHANNEL.
Examples
<lsl>//-- Open map for owner to 1st landmark in object inventory on touch //-- *MUST* be in an attached object (llMapDestination Requirement for non-touch use) key vgKeyOwner;
default {
touch_start( integer vIntNull ) { if (llDetectedKey( 0 ) == vgKeyOwner) { integer vIntLMcount = llGetInventoryNumber( INVENTORY_LANDMARK ); //-- make sure we have a landmark in invetory if (vIntLMcount) { llRequestInventoryData( llGetInventoryName( INVENTORY_LANDMARK, 0 ) ); } } }
dataserver( key vKeyNull, string vStrData ) { //-- because we don't know who touched us in this event, this //-- only works for the owner when called from the dataserver llMapDestination( llGetRegionName(), (vector)vStrData, ZERO_VECTOR ); }
on_rez( integer vIntNull ) { vgKeyOwner = llGetOwner(); }
}</lsl> <lsl>//An easily-configurable teleporter that sets its destination by getting it from a landmark in the prim's inventory //Note: this teleporter is subject to the 300m distance limit for llSitTarget //by Ilse Mannonen
//on state entry, request inventory data and set text for first landmark found in inventory. //If none, complain //on getting data, set sit target //on change in inventory, reset script //on sit, TP the person and unsit
//Thanks to Pol Tabla, who wrote the simple sit-teleport script I have adapted here

default {
state_entry() { //complain if there are no landmarks if (llGetInventoryNumber(INVENTORY_LANDMARK) == 0) { llSay(0, "There are no landmarks in me.
