LlGetLinkName/zh-Hant
概要
函式: string llGetLinkName( integer linknum );
|
| |||||||||||||||||||||
注意事項
- The prim name attribute is limited to 63 bytes, any string longer then that will be truncated. This truncation does not always happen when the attribute is set or read.
- The only LINK_* flag that linknum currently supports is LINK_ROOT. SVC-600
- Use llGetLinkNumber() as the parameter to retreive the prim's name, not LINK_THIS.
範例
Listen on channel 10 for a name; check if a prim with that name is part of this object <lsl> integer check_for_prim(string name) {
integer i = llGetNumberOfPrims();
for (; i >= 0; --i)
{
if (llGetLinkName(i) == name)
{
return TRUE;
}
}
return FALSE;
} default {
state_entry()
{
llListen(10, "", llGetOwner(), "");
}
listen(integer chan, string obj, key id, string msg)
{
if (check_for_prim(msg))
{
llOwnerSay("found a linked prim named \"" + msg + "\"");
}
else
{
llOwnerSay("this object does not have any linked prims named \"" + msg + "\"");
}
}
}</lsl>
筆記
Link Numbers
Each prim that makes up an object has an address, a link number. To access a specific prim in the object, the prim's link number must be known. In addition to prims having link numbers, avatars seated upon the object do as well.
- If an object consists of only one prim, and there are no avatars seated upon it, the (root) prim's link number is zero.
- However, if the object is made up of multiple prims or there is an avatar seated upon the object, the root prim's link number is one.
When an avatar sits on an object, it is added to the end of the link set and will have the largest link number. In addition to this, while an avatar is seated upon an object, the object is unable to link or unlink prims without unseating all avatars first.
Counting Prims & Avatars
There are two functions of interest when trying to find the number of prims and avatars on an object.
llGetNumberOfPrims()- Returns the number of prims and seated avatars.llGetObjectPrimCount(llGetKey())- Returns only the number of prims in the object but will return zero for attachments.
integer GetPrimCount() { //always returns only the number of prims
if(llGetAttached())//Is it attached?
return llGetNumberOfPrims();//returns avatars and prims but attachments can't be sat on.
return llGetObjectPrimCount(llGetKey());//returns only prims but won't work on attachments.
}
Errata
If a script located in a child prim erroneously attempts to access link 0, it will get or set the property of the linkset's root prim. This bug (BUG-5049) is preserved for broken legacy scripts.
