Random/Variable Mes

[Azura Skyy]

I'm want to know if it is possible to have an NPC greet the player with a random message (of some 5-10 message for example), and how I would do that. Sorry if it's a stupid question, I usually have someone else doing my scripting.

 

I've been looking through the rAthena wiki at various scripting commands (var/rand/array) and I can't seem to find the solution to my question.

This is taken from the rAthena Wiki article on Variables

If you are using the mes command, or another text displaying command, it works a bit differently:

mes #var; // Will display a line with only the value of #var.
mes "You have killed " + dead_porings + " Porings.";  // Will display this: 
						      // "You have killed <value of dead_porings>
						      // Porings."
mes @name$; // If @name$ contains "[Kafra]", it will display "[Kafra]"
mes "My name is "+@name$; // If @name$ contains "Trevor", it will display: "My name is Trevor"

 

Any help is appreciated. If possible, please provide an example script.

Thanks in advance,
~Azura Skyy

You can use the F_Rand function in /npc/other/Global_Functions.txt

.

mes callfunc("F_Rand","Mes 1","Mes 2");

I'm not a big scripter, but you could try the following : 

setarray .@greetingMessages$[0], "have a nice day", "message2", "message3";
.@greetingId = rand(0,getarraysize(.@greetingMessages$) - 1);
mes "Hello player, " + .@greetingMessages$[.@greetingId] + ".";

mes "Hello player, " + .@greetingMessages$[.@greetingId] + ".";

 

Looks promising. I'm having difficulties with VNC at the moment, so I'm unable to test this, but I'm sure I'll get an opportunity to sort things out tomorrow night.

Thanks in advance,

I'd like to thank both of you, as both of these solutions work perfectly, of course, Nerfwood's is a much cleaner solution to my particular problem.

Tokei, your solution will still be used for the NPC I originally intended this for, and to make it work as a 'random message' I just changed the text.

mes "Hello player, " + .@greetingMessages$[.@greetingId] + ".";

Changed to

mes "" + .@greetingMessages$[.@greetingId] + "";

With that, it functions purely as a 'random message.' Thanks for your reply. Much appreciated!

Nerfwood, as I said before, your solution is definitely a lot simpler and cleaner. I'm using your solution for an NPC as well. Always nice to see multiple ways of going about a solution and it's taught me a bit more about scripting.

Thank you both,
