llInstantMessage() and newline (\n) characters...

Does llInstantMessage() fail when the message text contains \n characters?

I tried to write a script using this, but the IM is not delivered. I checked the key using llKey2Name and it's my key... I tested the string using llOwnerSay and it displayed it fine... So I can only think it's a problem with llInstantMessage... Does anyone know?

From the wiki:

From: llInstantMessage

Note: If message exceeds 1023 bytes (excluding null), it will be truncated. String length can be determined with llStringLength.

For a multi-line message, use new lines:

"This is on one line.\nThis is on another line."

However, bear in mind that this will display as a single line if the chat history window is closed, but will show up appropriately if it's open.

I'm testing llInstantMessage now sending something to myself and I'm getting no response back, whether I use \n or not.

Seems like a bug, or a current issue. According to stats, the sim I'm in is in near-perfect health.

Whatever the hiccup was, it seems to be working again now at least for me.

It was failing after every save and re-run, then I happened to get an asset error once, but after that it had no problems.

CODE

default
{
	state_entry()
	{
		llSay(0, "Hello, Avatar!");
	}

	touch_start(integer total_number)
	{
		key avatar = llGetOwner();
		
		llOwnerSay("Owner Say");
		llWhisper(0, "Whisper");
		llSay(0, "Say");
		llInstantMessage(avatar, "Single line IM");
		llInstantMessage(avatar, "Multi line IM\nMulti-line IM");
	}
}

I just tried it again though, didn't change the llInstantMessage call at all, just changed my string concatenation to add \\n instead of \n, and the IM came through.

Soooo... Something tells me the function just refuses to work with \n chars.

Weird tho! I tried it with a manually constructed string, and it worked O.o

Bah... fixed it. Put some extra checks and processing into the string concatenator... There must have been some extra trailing newlines or something freaking the llInstantMessage function out (Although llOwnerSay was fine with them O.o).
