Issues with sending message to titler from custon app

[arielxekri]

This is probably a bug with my code rather than the collar but I'd be really grateful for a steer in the right direction. Have a plugin app that I'm working on - used the plugin template and it all works great except this bit that is designed to turn on off titles, it turns them on fine and changes them as required but I cant turn them off again - here's the code

titlermessage(integer show, string txt, vector col){
if (show==FALSE){
llMessageLinked(LINK_SET, LM_SETTING_DELETE, "titler_show","");
}
else{
llMessageLinked(LINK_SET, LM_SETTING_SAVE, "titler_show=1","");
llMessageLinked(LINK_SET, LM_SETTING_SAVE, "titler_title="+llStringToBase64(title_text),"");
llMessageLinked(LINK_SET, LM_SETTING_SAVE, "titler_color="+(string)colour,"");
}
}

I've tried llMessageLinked(LINK_SET, LM_SETTING_SAVE, "titler_show=0",""); but that doesnt help and looking at the titler code the setting delete line seems to be what's used there.
what do I need to do to turn them off - please!
thanks

Hi @arielxekri. The Titler app isn't written to handle other scripts modifying the settings, so while deleting the titler_show setting is the correct method, the titler script won't actually clear the title on that setting being deleted, and wouldn't update the title until the next time it receives an LM_SETTING_RESPONSE message. Normally this would be on the next attach / reset. This could be triggered artificially, however that's really not the way to do this.

For an external app to change the title, the best approach would be to send link messages that will be processed with the UserCommand function, i.e with the iNum value being an auth value between CMD_OWNER (500) and CMD_WEARE R(503). Best practice would be to use the auth value of the person using the app to respect the auth levels the Titler function uses, though sometimes a "fake" CMD_OWNER command might be sent internally to ensure something happens. Thus:

llMessageLinked(LINK_THIS,iAuth,"title "+sNewTitle,kID); -- changes title
llMessageLinked(LINK_THIS,iAuth,"titler show",kID); - shows title
llMessageLinked(LINK_THIS,iAuth,"titler hide",kID); - hides title

---where iAuth is the Auth value of the app user or could be replaced with 500 to bypass authing, kID is their key, and sNewTitle is a string containing the text to change the title to. Sending these functions to be handled by UserCommand() will trigger the change AND handle saving settings for you.
