SOLVED Usage of the plugin function WantsToDisplayMessage()

Hi,

I'm trying to use WantsToDisplayMessage() to display a simple message in the chat
when my plugin starts up correctly.

I can't seem to do that. This is the relevant part of the code I'm trying to use:

Code:

bool WantsToDisplayMessage( MessageInfoV01 &msgInfo )
{
    static bool displayed_welcome = false;
    static const char message_text[128] = "Delta-Best Plugin enabled!";

    if (! displayed_welcome) {
        displayed_welcome = true;
        msgInfo.mDestination = 1;     /* Chat */
        msgInfo.mTranslate = 0;     /* Don't translate */
        strncpy(msgInfo.mText, message_text, sizeof(message_text));
        return true;
    }

    return false;
}

What am I doing wrong?

 

Have you tried strlen instead of sizeof?

 

You have to return true not false.

 

Does it work if you send it to the message center (msgInfo.mDestination = 0; ) instead of the chat?

 

I do return true, the first time only.
Maybe I don't understand what you mean?

 

Tried, it doesn't work.

 

Yeah I just slimed your code. So what is it doing? Crashing the game or just not sending the msg?

 

No crash and no message. Rest of the plugin just works fine.

 

I see the problem. You are initializing displayed_welcome everytime so it is always going to be set to false before you test. You need to move move that variable out of the function and into a global area.

 

Tried returning always true, doesn't work either.
Tried deriving from V05 and V06. Same thing.

 

Oh, ok, then I misunderstood how static works in methods.
Thanks, I'll try that. I'm sure it will work.

 

Nothing yet. I tried a few more things but it seems to never work for me.

 

Here's a copy of code from a plug-in I wrote a while ago, and this does display a message in the message center:

Code:

bool LapDistancePlugin::WantsToDisplayMessage( MessageInfoV01 &msgInfo ) {
    if (mReportLapDistance == true) {
        msgInfo.mDestination = 0;
        msgInfo.mTranslate = 0;
        sprintf(msgInfo.mText, "Distance: %.0lfm", mLapDistance);
        mReportLapDistance = false;
        return true;
    }
    return false;
}

Edit: Ah, could it be the "<class name>::" prefix that is missing in your code? In that case it just becomes a local method I think, which would explain that it doesn't work. It's simply never called.

 

Bingo! Thanks Jorgen, that must be the problem, no doubt (the missing class name).
I haven't tried yet, but I'm going to in a few minutes

 

The missing class name was one problem.
The other was that I have to wait until the EnterRealtime event before sending a message, or the message will be lost!

 

Are you sure it is lost or is this something to do with the 15sec delay before the plugin is loaded? I hate this stupid delay when trying to troubleshoot.

 

Well, the plugin is indeed loaded before EnterRealtime.
The message is triggered as soon as the plugin icon goes away now, so I'm happy

 

Is this supposed to work with DX11? I have spent an hour now testing, and the function doesn't seem to be called at all.

 

Solved... Was using the wrong plugin version...
