This table tells whether an implicit type cast is supported by llList2*
depending on the item type in the list. Last tested with this server version: Second Life Server 11.10.18.243270
Updated 2011-10-30 with note on unsupported llList2Key conversions in LSO, which weren't tested before
List item type: Function: |
string | key | integer | float | vector | rotation |
---|---|---|---|---|---|---|
llList2String | YES | YES | YES | YES | YES | YES |
llList2Key | YES | YES | no | no | no | no |
llList2Integer | YES | no | YES | YES | no | no |
llList2Float | YES | no | YES | YES | no | no |
llList2Vector | no | no | no | no | YES | no |
llList2Rot | no | no | no | no | no | YES |
The non-supported conversions for llList2Key
return (key)""
in Mono, and (key)NULL_KEY
in LSO.
The non-supported conversions for llList2Integer
return 0
.
The non-supported conversions for llList2Float
return 0.0
.
The non-supported conversions for llList2Vector
return ZERO_VECTOR
.
The non-supported conversions for llList2Rot
return ZERO_ROTATION
.
In short: llList2String
can be applied to all types. A string element can be extracted by all functions except llList2Vector
and llList2Rot
. llList2Integer
can extract a float, and llList2Float
can extract an integer. No other implicit conversions are supported.

Here's the program used to elaborate the above table:
string CheckResults(integer ExpectedYes, integer ExpectedNo)
{
if (ExpectedYes && ExpectedNo)
{
// Inconsistent check - revise code
return "*INCONSISTENT*";
}
if (!ExpectedYes && !ExpectedNo)
{
// Neither of the checks is met
return "*UNEXPECTED*";
}
if (ExpectedYes)
return " YES";
return " no ";
}
string v2s(vector v)
{
return "<"+(string)v.x+", "+(string)v.y+", "+(string)v.z+">";
}
string r2s(rotation r)
{
return "<"+(string)r.x+", "+(string)r.y+", "+(string)r.z+", "+(string)r.s+">";
