Trigger Client NPC

[Pelikano]

Is there any way to trigger a clientside-function in an NPC?

[Skyld]

There have been many threads about this already, please use the forum search function. You'll also have to be more specific as to what type of NPC (level NPC?) or a little bit more about what it does.

Sorry, didn't use the search function :

PHP Code:

function onCreated() {
  if (blablabla) {
    // trigger the client
  }
}
//#CLIENTSIDE
function onClientSideFunction() {
  // Stuff
} 


Something like this

No, you normally can't trigger client like that. Think about it: It'd have to trigger client for every player in the level, right? Unless of course you did something like player.triggerclient.

However, I don't think it works for DB NPCs (putnpc2, for example).

I could be wrong, though.

In that example you could just have the onCreated() function on the clientside, no trigger needed (I'm assuming it's a DBNPC via putnpc?).

If the conditional statement 'if (blablabla)' can only be read serverside, I suggest storing the data in some other way where it could be read on the client.

Edit: what I'm trying to say is that there's most likely a way to do it without needing a server->client trigger and you should be more specific with your problem.

I don't have a problem, it would just be handy if you could trigger a function on the Client in a level NPC ;D

could you not just do

NPC Code:

---

triggeraction(this.x, this.y, "clientside", "params");

//#CLIENTSIDE

function onActionClientside() {

  

}

---

etc?

Doesn't work with NPCs that don't have a shape(aka non-blocking), and if there are other NPC's at the same space, they will get the triggeraction instead.

So what do you suggest? I was looking for something like this the other day actually.

[DustyPorViva]

It's fairly easy to send data from serverside > clientside via attr[]'s. You can do checks like that if you'd like.

What I also did was set-up a DBNPC that would intercept the triggerserver's/triggerclient's from the local NPC, and then do the communication in the DBNPC itself and then resend the function. However, I only did this for clientside > serverside, so I'm not particularly sure of how that'd work the other way around

DBNPC:

PHP Code:

function onActionServerside(cmd,lvl,checkid) {
  if (cmd == "checkhit") {
    for (temp.i: findlevel(lvl).npcs) {
      if (i.id == checkid) {
        i.test();
        break;
      }
    }
  }
} 


And in the level itself(from the clientside):

PHP Code:

triggerserver("npc","mydbnpc","checkhit",this.level.name,this.id);

could have sworn triggerclient() worked?

[Angel_Light]

It does, but not in the way I think you want it too.

NPC Code:

---

triggerClient( "gui", name, params...);

---

PHP Code:

function onCreated()
{

  for ( temp.pl: allplayers)
  {

    pl.triggerClient( "gui", name, "Hello World");

  }
}

//#CLIENTSIDE

function onActionClientside()
{

  player.chat = params[ 0];

} 


I know you can replace "gui" with "weapon" but it still does the same. Can someone enlighten us if there is any difference.

For level NPC's you just have to define the shape, such as

NPC Code:

---

setshape( 0, 16 * 2, 16 * 3);

---

0 being non-blocking.

Then you can do the triggerAction();

example

PHP Code:

function onCreated()
{

  triggerAction( this.x, this.y, "Clientside", "Hello World");

}

//#CLIENTSIDE

function onCreated()
{

  setShape( 0, 16 * 2, 16 * 3);

}

function onActionClientside()
{

  player.chat = params[ 0];

} 


Also, you dont have to use "Clientside" since it's a triggerAction(); So replace that with something like "Data" then the function would be onActionData()

[Robin]

It really does need a way of directly calling a function on the clientside of the current DBNPC / Level NPC.

[Angel_Light]

My first method works for dbNPCs and second for levelNPCs. Both methods have worked for me.

[Pelikano]

Thanks Angel,

but your second method doesn't work.
You cannot use triggeraction() from server to client as it seems..

Yes you can.. ?

[Angel_Light]

you might want to put this.x + 0.5 and this.y + 0.5 in the triggeraction since it is calling it on the border. I found doing that usually fixes it.

Sounds like you never setshape on the serversided part of the NPC tbh.

Both work, but probably setting setshape may sound more efficient.

[DustyPorViva]

Triggeraction probably won't work if the shape of the NPC isn't set on the serverside. This is because without a serverside setshape, the NPC server won't be able to 'find' the NPC when you do the triggeraction(since triggeraction uses blocking space only to trigger, and non-blocking will not register).

[Angel_Light]

setshape isnt always blocking per sei, if you just do setshape( 0, 32, 32); zero will make it non-blocking
