Using a Link Message

[Lemar6000]

Help Please ...

This first part is a segment of a menu driven texture changer script that is "Touch Start" and I am trying to get it to start form a Link Message from Menu in the same prim.  This script does work.

default
{
    state_entry()
    {
        composelist(); //make list from inventory textures
    }

    touch_start(integer total_number)
    {
        user = llDetectedKey(0);
        menu(user,"Please select one below.",texture_list);
    }
    
    listen(integer channel,string name,key id,string message)
    {
        if (channel == menu_channel)
        {
            llSetTimerEvent(0.0);
            llListenRemove(menu_handler);
            if(message == "Next Page")
            {
                menu(user,"Please select one below.",texture_list2);
            }
            else if(message == "Last Page")
            {
                menu(user,"Please select one below.",texture_list);
            }
            else
            {
                llSetTexture(message, side);
            }
        }
    }

 

This is the same segment that I have tried to modify to start with a Link Message.  The Bold area is the part I changed.   The Menu never appears. Any Ideas?

default
{
    state_entry()
    {
        composelist(); //make list from inventory textures
    }

    link_message( integer sibling, integer num, string mesg, key target_key )
    {
        if (mesg == "texture")  
        {   
            user = llDetectedKey(0);
            menu(user,"Select a Texture .",texture_list);
        }
    }
    
    listen(integer channel,string name,key id,string message)
    {
        if (channel == menu_channel)
        {
            llSetTimerEvent(0.0);
            llListenRemove(menu_handler);
            if(message == "Next Page")
            {
                menu(user,"Please select one below.",texture_list2);
            }
            else if(message == "Last Page")
            {
                menu(user,"Please select one below.",texture_list);
            }
            else
            {
                llSetTexture(message, side);
            }
        }
    }

The llDetected* functions (as in user = llDetectedKey (0)) don't work in a link_message event, so the user you're targeting is the NULL_KEY.

Make sure that the script that's sending the link message has the key for the target user in the key parameter of the llMessageLinked function, something like: llMessageLinked (LINK_SET, 0, "texture", llDetectedKey (0)), and then use that parameter in the call to your menu function: menu (target_key, "Select a Texture.", texture_list).

Perfect!  Thank you!
