More fun with clientside and serverside
 

Okay. So say I have an event and I want to do five things. Two are serverside, three are clientside. How do I do this? More realisticly, say I have sixteen events and want each to do 8 things, 4 serverside and 4 clientside. Is there a way to do it without running the script twice (once above the //#CLIENTSIDE and once below it)?

Well, you wouldn't want to run the same script on both clientside and serverside for the obvious reason - the clientside will do some things that the serverside won't and the serverside will do some things that the clientside won't. The NPC-Server won't exactly spit fire if you, say, try to use showimg on the serverside, but it's overall not recommended.

What you need to do is arrange your script so that the serverside and clientside can work together; that's if I've understood what you're trying to do properly, of course. For example, if you want to display pictures on the clientside that warp players when you click them, then you'll want to have the image display and the click detection on the clientside, and triggeraction to the serverside to warp the player.

If you're using a weapon, you can do the following (GScript2):

NPC Code:

---

function onActionserverside()

{

  if (params[0] == "foo")

  {

    sendtonc("bar");

  }

}

//#CLIENTSIDE

function onMouseDown()

{

  triggeraction(0, 0, "serverside", "Weapon/Name", "foo");

}

---

Or GScript:

NPC Code:

---

if (actionserverside)

{

  if (strequals(#p(0), foo))

  {

    sendtonc bar;

  }

}

//#CLIENTSIDE

if (mousedown)

{

  triggeraction 0, 0, serverside, Weapon/Name, foo;

}

---

In these examples, you would put the player warping (or whatever) on the serverside, and the detection of you clicking on the clientside.

If you're not using weapons, then you can still triggeraction to the serverside by triggeractioning on the NPC's coordiates instead of triggeractioning to (0,0).

I hope this is of some help.

I can just use the x and y variables to work as the NPCs x and y no matter where the NPC is, right?

And also, for triggeractioning to the serverside, you can only have one NPC in the entire level with that specific action event condition or else all NPCs with that action event condition will be triggered, right?

Yes, but you must triggeraction onto the object, maybe a setshape surface.

Edit: May not be the same on GMAPs however. GMAP X and Ys are not always level X and Ys.
Not quite. The action will only happen for NPCs on the triggered position, or for the specified weapon name.

I can trigger from the serverside to the clientside too, right?

Currently, only in weapons. There are two ways that I know of to do this in GS2:
The second way uses 'triggerclient()', but since I don't know the syntax by heart, I won't post it here. :D

So how do I send a message from the serverside to the clientside for the clientside to execute some clientside commands?

Serverside created is not called in weapons.

I think it is, but not for when the weapon is created for the player, but when it is updated (created).

That works on a weapon script when it's updated.

But yes... triggering clientside from a serverside onCreated() in a weapon will not work.

That does not count. =P
