Grrr... simple controller and listener for color change, but doesn't work

I'm trying to modify a texture change script with a controller and listener into a color change script, also with controller and listener, so I can put the listener in the prims (of a linked set) that need to be changed.

But I can't get it to work. I've changed color values to vector values, but when I touch the prim it turns to black. What do I do wrong?

CONTROLLER:

list ColorNames = ["White", "Gray"]; 

list ColorKeys = ["<1,1,1>", "<.5,.5,.5>"]; 

integer menu_handler; 
integer menu_channel; 

string ON; 
key Dkey; 

default 
{ 
    touch_start(integer t) 
    { 
        Dkey = llDetectedKey(0); 
        ON = llGetObjectName(); 
        menu_channel = (integer)(llFrand(99999.0) * -1); 
        menu_handler = llListen(menu_channel,"",Dkey,""); 
        llDialog(Dkey,ON + " Color Selection Options:", ColorNames, menu_channel); 
        llSetTimerEvent(15.0); 
    } 
    timer() 
    { 
        llSetTimerEvent(0.0); 
        llListenRemove(menu_handler); 
    } 
    listen(integer chan, string name, key id,string msg) 
    { 
        if (chan == menu_channel) 
        { 

            
            llMessageLinked(LINK_SET, -9775, "", llList2Key(ColorKeys, llListFindList(ColorNames, (list)msg))); 
            
             
            llDialog(Dkey,ON + "Color Selection Options:", ColorNames, menu_channel); 
            llSetTimerEvent(15.0); 
        } 
    } 
}

LISTENER:

default 
{ 
    link_message(integer snum, integer num, string str, key id) 
    { 
        if(num == -9775) 
        { 
            llSetColor( (vector)str, ALL_SIDES ); 
        } 
    } 
}

Unless it is too late at night and I'm seeing cross-eyed, you are passing a key holding the color information in your llMessageLinked statement, but listening for a string in your Listener. Since the listener is never getting values, it is filling in <0,0,0>, which is black.

Why don't you use llSetLinkColor?

I know this is not a reply to your question, it's another question, but maybe it helps

You can't pass a key via llLinkedMessage()...

Thus: llMessageLinked(LINK_SET, -9775, "", llList2String(ColorKeys, llListFindList(ColorNames, (list)msg)));

The typecast in the listener-event should work fine, though...

Here is one method I use..

Sample:

if (llGetLinkNumber() == 1) llSetLinkColor(LINK_SET, color_vector, ALL_SIDES);

Haruki:

I guess I'm confused about the syntax and operation of llMessageLinked. The order of values sent is (integer linknum, integer num, string str, key id).


llMessageLinked(LINK_SET, -9775, "", llList2String(ColorKeys, llListFindList(ColorNames, (list)msg))); produces a string value in the key position. The string position is sending "". The listener is set up to receive a string in the string position. Does the order of the values sent not matter?

No but with llMessageLinked() it works just fine, I do it all the time

llMessageLinked(LINK_SET, -9775, "", llList2Key(ColorKeys, llListFindList(ColorNames, [msg])));

I was right the first time. To fix the script, replace the two lines as follows:

list ColorKeys = ["<1,1,1>", "<.5,.5,.5>"];


llMessageLinked(LINK_SET, -9775, llList2String(ColorKeys, llListFindList(ColorNames, [msg])), NULL_KEY);

Now it works.
