Hi there, someone can answer to this question?

is there a trick in Neverwinter Nights 2 scripting (or other) to change the timing of the "OnHeartbeat" of an Area (that is about 6 seconds)  ??

If i have to do an operation in my script about 4 times per second how can i do it ??

Maybe a "while cicle" in the script assigned to the "OnHeartbeat" event of the Area ??

thanks for answers !!

Same for nwn2.

Thanks a lot !!

I will try it, obviously are welcome even other solutions or tricks :-)

I use the SetCustomHeartbeat() function. To make it 4 seconds, write:

object oArea = GetObjectByTag("your_area_tag");
SetCustomHeartbeat(oArea, 4000);

Edit:

Ah, you want 4 times per second, not every 4 seconds.  In that case,

SetCustomHeartbeat(oArea, 250);

Great !! :-)

It's good to hear that SetCustomHeartbeat() works on areas as well as on creatures. It certainly doesn't work on placeables (including iPoints).

[Tchos]

It should be said that I haven't tried it on an area. My experience has been from using it on creatures. Some testing would have to be done.

I went and tested this, and I think you'll be happy to find that it does.  I have a heartbeat script on the two placeables in this video (a wine crate, and an ipoint), and I've used SetCustomHeartbeat(OBJECT_SELF, 1000) to give them 1-second heartbeats.  In the video, you can see that their SpeakString() calls are being executed every 1 second.

You could always use a general script, not a heartbeat...

adding the following to the area oncliententer:

void MyOperation(object oObject)
{
//something to make sure this only runs while the player is in the area
//change this or remove it depending on what you want done... could also use a
// GetIsObjectValid(oObject) to make sure you're not running it when object is gone
// too many heartbeat functions in a module will ruin other things, like Kaedrin's
if(GetTag(GetArea(GetFirstPC()))==GetTag(GetArea(oObject)))
{
//***insert whatever you want done here***
// a delay of 0.25 s to run this again...
DelayCommand(0.25,MyOperation(oObject))
}
}

Excuse me Tchos but exactly how should i use your trick ?

Must i put the two lines of code in a script assigned to the "OnHeartbeat" of the area ??

Demo

In Crimmor, the item Evercarpet relies on ipoints with very short custom heartbeats to produce it's effect when used.

You could do that, but I wouldn't recommend it.  It would be more efficient to put the lines in some place where they'd only be run once (or at least only once per visit), because you don't need to set the heartbeat over and over.  You could put it in your area's On Client Enter slot, for instance.

If you do put it in the actual area's script set, then you don't need the first line.  You could use "OBJECT_SELF" to refer to the area.

I'll have to check that out.

Mmmm something doesn't work :-(

1- I have an area whose Tag is "area1"

2- I assign a script to the "On clientEnter" event of this area; the script is the follow:

void main()
{
object oArea = GetObjectByTag("OBJECT_SELF");
SetCustomHeartbeat(oArea, 250);
}

3- I assign a script to the "On HeartBeat" event of the area; the script is the follow:

void main()
{
int h = GetCustomHeartbeat(GetObjectByTag("OBJECT_SELF"));
SendMessageToPC(GetFirstPC(), "message ! " + IntToString© + " heart= " + IntToString(h));
}

The value of "h" is always "0" and the message appears every 6 seconds, so the new definition of the heartbeat doesn't work !!!

[Tchos]

I'm sorry, let me explain. There are certain constants in the game like "OBJECT_SELF", which always refer to the object that fires the script. For those objects, you don't need to use GetObjectByTag() (although you could if you wanted to -- just not with "OBJECT_SELF" as a tag, because it's not a tag). Since the script is fired by the Area object, OBJECT_SELF is the area. This is how it should look.

void main()
{
    object oArea = OBJECT_SELF;
    SetCustomHeartbeat(oArea, 250);
}

Or, you can skip the first line entirely, and write:

void main()
{
    SetCustomHeartbeat(OBJECT_SELF, 250);
}

Or, you could also write it like this, since your area's tag is "area1":

void main()
{
    object oArea = GetObjectByTag("area1");
    SetCustomHeartbeat(oArea, 250);
}

Thanks of the explain Tchos... but the problem remains ! :-(
Maybe the SetCustomHeartbeat doesn't work with an area?

Could you send me the module which you used to do yours "Demo" video ???

[Fabb_u]

Ok, i tried the scripts with a creature and seems to work... so i think that is the Area object the problem

[Tchos]

I did my own test on an area, and I confirm that it doesn't seem to work on areas. Sorry for the false lead. You probably don't need the test module anymore.

From this point, though, if you still want to use the custom heartbeat, could you put your script (whatever you want to do with this heartbeat) on an ipoint in the area instead of on the area itself?

[Fabb_u]

I put the scripts in a creature which will follow the player and which is immortal ... is it possible to made this creature "like there isn't in", so invisible to opponents, ecc .. ?

[Tchos]

It would help give better advise if you explain what you're trying to do with it.

[Fabb_u]

I need to gather some info from the game (i.e. position of the player, health, inventory, ecc) and save them in the log file.
I think to use this creature like an "observer" to take this info about 4 times per second: this creature has to be "invisible", not a member of the party ... it must not enjoy battles, not interact with enemies or npc ecc.

[Tchos]

Then you don't need to have a creature follow the PC around. An ipoint can be placed anywhere and gather that information from the player. It doesn't even have to be in the same area.

[Dann-J]

I tried altering the HB rate of an iPoint once, and it didn't seem to work. It was on an overland map, but I don't think that should have any effect (although I *have* noticed some things that behave strangely on OLMs). I ended up using a script-hidden rat with its AI on, which did the trick.

I wanted fading footsteps to appear behind the player as they moved across the overland map, and once every six seconds wasn't nearly frequent enough (unless the player was a kangaroo). 'Track Rat' does his job brilliantly though. He even offsets the tracks slightly to either side in alternate directions to make them look like actual foot or hoof prints.

[Lugaid of the Red Stripes]

In my tactics script, I just call a function from the heartbeat multiple times on a delay (DelayCommand(1.5,...), DelayCommand(3.0,...), DelayCommand(4.5,...)). Calling it from the main heartbeat means it gets shut down within a heartbeat's time if it's no longer needed.

[Fabb_u]

It seems that only a creature could do what i want, in other items it is impossible to change the heartbeat

[Tchos]

I must have a magic toolset, then.

Regardless, even if you use a creature, it doesn't have to follow the player around.
