LlSetObjectName

Wiki description

Sets the prim's name according to the name parameter.

Function notes

If this function is called from a child prim in a linked set, it will change the name of the child prim and not the root prim.

Caveats

The name is limited to 63 characters. Longer prim names are cut short.
Names can only consist of the 95 printable characters found in the ASCII-7 (non-extended) character set, with the exception of the vertical bar/pipe ("|") character.
- Invalid characters in the range 1 to 31, as well as the pipe character (124) are replaced with a question mark ("?").
- Other invalid characters in the range 128 and above are replaced with two or more question marks, depending on how many bytes their UTF-8 representation requires.
- Objects with all-whitespace names (e.g., a space or a series of spaces) will appear as "(Unnamed)" if they emit chat via llSay, llOwnerSay, llInstantMessage, etc., although this behaviour may vary in third-party viewers.
While an object is attached, the script cannot change the name of the object as it appears in the user's inventory.^{Whether or not this is a bug is still debated, regardless LL has said they will not fix it. This behavior was first recognized as a pain point in 2006 and only confirmed to be lava-flowed more recently (2011).}
- Changes to the name of the root prim (with llSetObjectName for example) will not be saved to inventory; when the attachment is detached (to inventory, not dropped) this name change is discarded and the name in inventory is used instead.
- When attachment is dropped (to the ground) and taking it into inventory, the inventory item will have the new name (not the old).
Changes to the names of child prims will be saved back to inventory when the object is detached to inventory. They survive detachment.
Changes to the object name do not trigger a changed event.

Examples

Set this prim's name Set the root prim's name

default
{
    state_entry()
    {
        llSetObjectName("NEW PRIM NAME");
    }
}

default
{
    state_entry()
    {
        llSetLinkPrimitiveParamsFast(LINK_ROOT,
            [PRIM_NAME, "NEW ROOT PRIM NAME"]);
    }
}

Test if a string is valid as an object name

// Returns TRUE if 'name' is a valid object name, FALSE otherwise
integer isValidObjectName(string name)
{
    string original_name = llGetObjectName();
    llSetObjectName(name);
    integer valid_name = llGetObjectName() == name;
    llSetObjectName(original_name);
    return valid_name;
}
