Simple Show/Hide Script

I spent forever looking for a script with just a show hide feature for the objects I've started building, but had no luck here in the forum, or in game. So with the little programming experience I have, I looked up the SL scripting site and put together this little bit of script that will let you hide and show your poseballs or other objects with a simple channel check and typing either "show" or "hide". I'm sure others are better, and many are available in some circles, but I just decided to post this for anyone else that needed a quick, usefull script.

show()
{ 
    llSetAlpha(1.0, ALL_SIDES); 
} 

hide() 
{ 
     llSetAlpha(0, ALL_SIDES); 
} 

default
{
    state_entry()
    {
        // listen on channel zero for any chat spoken by the object owner.
        llListen(1,"",NULL_KEY,"");
    }
    
    listen(integer channel, string name, key id, string message) 
    { 
        if(llStringLength(message)!=4) 
            return; 
         
        message = llToLower(message); 
         
        if(message == "show") 
        { 
            show(); 
            return; 
        } 
        if(message == "hide") 
            hide(); 
    }
}

You can change the channel to listen for to every channel by changing llListen(1,"",NULL_KEY,"" to llListen(0,"",NULL_KEY,"". You can also change the "1" to any channel number you wish. Just copy and past into a new script and make any changes. Enjoy.

This makes the root prim alpha, but not an object. Is there an easy way around this?
