Where or how add these lines:

m_NextSpeakTime = DateTime.Now + ( TimeSpan.FromSeconds( 10 ) );
Say( m_Phrases[Utility.Random( m_Phrases.Length )] );

to make vendors talk randomily? It is very nice feature, if you played Gothic, you know what am i talking about...

Packer898 · Sep 7, 2005

Do something like this so that when a mobile enters within whatever range you deceide then the npc will talk.

Code:

		public override void OnEnter( Mobile m )

What method inside?
I think this will only trigger vendor talking... I would like to make that it does not depend from player when vendor talk. So maybe he should start talking after server start, but... how to do that?

Packer898 · Sep 7, 2005

Well you will probably need to cast mobile to playermobile then add a check for the distance and the time.

Galfaroth · Sep 7, 2005

Emmm... any hints how to do this

??

rsmiller21 · Sep 7, 2005

I used to have one of these guys on my shard. Here is a code snippet from the mobile:

Code:

private DateTime m_NextTalk;
		public DateTime NextTalk{ get{ return m_NextTalk; } set{ m_NextTalk = value; } }
            
		public override void OnMovement( Mobile m, Point3D oldLocation )
		{
			if ( DateTime.Now >= m_NextTalk && InRange( m, 4 ) && InLOS( m ) ) // check if it's time to talk & if mobile in range & in los.
			{
				switch ( Utility.Random( 4 )) //the amount of lines you have it to choose from
				{
					case 0: Say("Please read the Welcome Board"); break; //line 1
					case 1: Say("Obey all signs!"); break; //line 2
					case 3: Say("Have you checked your packback?"); break; //line 3
				};
				m_NextTalk = (DateTime.Now + TimeSpan.FromSeconds( 10 )); //channge the number 10 to the min amount of seconds to wait between talks.
			} 
		}

Not sure if this will work in basevendor... but give it a shot. Good luck.

Galfaroth · Sep 7, 2005

Yea but you see... Player moves and 6 vendors start to talk at the same time... this is not this what i want.

Packer898 · Sep 7, 2005

Then script what you want. If your not willing to script it yourself then you will have to make do with what is given to you. Beggars cant be choosers.

You can easily change the distance to 2 tiles or 1 tile to keep this in check.

Galfaroth · Sep 7, 2005

But I'm not sure you know what I'm trying to do... Npc's don't have to talk to player... They have to talk to themselves, to air, without player... It's their own life like in topic's name... I don't know how to do this kinda thing...

Ok its still the same exact thing that rj just showed you in the code he GAVE you. You dont want all 200 NPC's using a timer and talking when no one is around to see this. It would eat ALOT of resources and cause great amounts of lag. The only time this needs to happen is when a player is around to see it otherwise its all for nothing.

Use the code he gave you and then modify it so they speak on movement. I have already told you that you can change the range then just modify the speech patterns to whatever you want.

Galfaroth · Sep 7, 2005

Ok, I change range to 2, so only one NPC will say something... But I want all npc on the screen to talk with themselves, even if player doesn't move... OnMovement isn't correct here I think, but what is?

Packer898 · Sep 7, 2005

Then use a timer. The only problem with using a timer is whether or not anyone is around to see this the NPC's will continue to speak. Using a timer for 100+ NPC"s is a really REALLY bad idea. You are going to have a laggy shard. But its your world so do what you want.

edit--- You can also use the OnThink method for this as well...

Galfaroth · Sep 7, 2005

Isn't there override void (or sth like this) like OnSee (similar to OnMovement) ?? Then timer starts when player see npc or when player is in range of NPC ??

Packer898 · Sep 7, 2005

Not that I know of. Check your documentation.

Galfaroth · Sep 7, 2005

Something like:
If npc is in playerrange(5) trigger talk?

Packer898 · Sep 7, 2005

lol BTW what would be the difference between an OnSee method and OnMove? Both would require the player or mobile to get into a range before saying anything?

You could just put a check in the OnThink method to see if a player is in range before executing the speech.

Packer898 · Sep 7, 2005

In the code Rj gave you there is a InLOS check... Line of Sight...

Galfaroth · Sep 7, 2005

There is difference. OnMovement trigger speech only if player moves... OnSee trigger if player just see npc... How about OnThink - how it works?

Let me see sth.

rsmiller21 · Sep 7, 2005

Working a timer right now.... going to add some vars to minimize lag

rsmiller21 · Sep 7, 2005

I got the timer it to work but the results could be disastrous.... With the code I gave you, you would have to place in every vendor you wanted to talk. You could set the "sight" to a longer distance so that once a player first sees the vendor/mobile come into the screen, he will already be talking. As for using that code in basevendor.cs, it is not possible(As posted) because you cannot override OnMovement because it doesn't exist. I am looking more into this right now. As for OnThink(). This function doesn't exist. It seems like you are trying to give your mobiles real AI. Sounds painful. I'll post again soon.
