setting colors using increase and decrease arrows?

Ok, this one has had me pulling my hair out


when I say /33 color <1,0.5,0> or whatever, it works fine

now if I have a HUD say llShout(33, "color <1,0.5,0>"; no problem

but if I do it this way

llShout(33, "color " + (string)<1,0.5,0>;

it only sets the first part of the color vector to 1.0000000 and none of the others.....

Do I have to convert the colors to 255 mode in order to make this work? I'm rather confused by this.

I'm not sure exactly how your implementing this, but I would make a vector before the shout. So for instance:

vector COLOR = <1.0, 0.5, 0>;
llShout(33, "color " + (string) COLOR);

Try that, see if it works

From the temporary lsl wiki:

Colours are vectors containing 0.0 - 1.0 normalized vectors. You need to divide 0 - 255 colour vectors by 255 before using them.

That just means that SL only takes numbers between 0 and 1, you can put in 0.254 for a value. If you have a color like R125, G200, B100, then you would have to divide them by 255 to get the corresponding values for llSetColor to work.

Maybe it has something to do with how you're converting the string in the listen at the other end back to a vector. I notice your first example had "color <1,0.5,0>" (with no spaces after the commas) but I'm pretty sure "color " + (string)<1,0.5,0> would actually be sent as "color <1.0, 0.5, 0.0>". I don't have SL handy to test atm so you'd have to double-check that, but there's another possibility for you to investigate anyway.

nah, he has spaces in all cases..

I have a script that i'm shouting a vector as well (on a negative channel) and it works fine.. using (string) Vector (i am putting it in a variable before I send it. yes.)

how are you retreiving it back out? using llGetSubString(string, 6, -1); ??

Edit: Scratch that.. if the /33 color: <blah> is working, then it isn't how youre retrieving it.. but the code you show there does look right. Perhaps double check that you havn't got a stray comma or something messing it up, and/or try a variable?

I can't say how many times I keep trying to enter <1.0, 0,5, 0.0> which for some reason it doesn't like.

use lots of llOwnerSay debugging commands:

 llOwnerSay ((string) whatVectorYouThinkItHasRead)

I have a similar item, non HUD though, that works using the following code

// iIndex is the index into the colour array            
vector vcolour = llList2Vector(lColours, iIndex );
string msg = "COLOUR:" + (string)vcolour;
llShout(chnnl,msg);

the receiver end is

    listen( integer channel, string name, key id, string message )
    {
        list lData = llParseString2List(message, [":"], [""]);
        string command = llList2String(lData, 0);
        string item = llList2String(lData, 1);

        if(DebugOn)
                     llOwnerSay("heard [" + command + "] [" + item + "]");

        if("COLOUR" == command)
        {
            vector clr = (vector)item;
            llSetColor(clr,ALL_SIDES);
        }

    }
