What function would I use to set a target's movement speed to Immobile?
I've tried EffectMovementSpeedDecrease(99) but that's not immobile, and it doesn't go up to 100%. I've searched the Lexicon for Movement and Immobile but I found options for oPC camera/cutscene, not the movement speed on the npc.

[Fester Pot]

effect eFreeze = EffectCutsceneImmobilize();
AssignCommand( OBJECT_SELF, ActionDoCommand(ApplyEffectToObject(DURATION_TYPE_TEMPORARY, eFreeze, OBJECT_SELF, 30.0)));

Change 30.0 for the duration you need to keep the NPC from moving about.

FP!

// Returns an effect that when applied will paralyze the target's legs, rendering
// them unable to walk but otherwise unpenalized. This effect cannot be resisted.
effect EffectCutsceneImmobilize()

[Buddywarrior]

Thanks guys, though the cutscene effect 'freezes' the monster, the mob doesn't go agressive. I've added damage and AssignCommand(oTarget, ActionAttack(oPC)) to try and get the mob to attack me while i'm within melle range, but no go.

I'm trying to duplicate the Root spell found in other games, and the closest I can see that in nwn is to switch the npc's movement to Immobilize. This allows range attacks to occur and for them to wack on the player if they are within range. Suggestions?

[wyldhunt1]

That may be related to a bug wherein an NPC with a speed set to immobile in the toolset won't reliably attack either.
You could probably add a check to the AI script to see if they have your spell effect on them and run a custom AI if they do. You'd have to code a bit to check for enemies within melee distance, else switch to a ranged weapon or cast. Just don't add any options that would involve moving or running.

EffectCutsceneImmobilize() really should work though...
I've just never tested it with the combat AI.
<Wonders if there's some check in the default AI that cancels out if the NPC is immobile>
I think that the AI does a few checks to see if the NPC shouldn't be able to attack and cancels out if it returns true. I'm fairly sure that it checks for stuff like paralyze, petrify, sleep, etc... I'll have to take a look at that when I get a chance.
It may be as simple as adjusting a check in the AI somewhere.

If you're using NWNX, you can do this with SetMovementRate. Otherwise, I know of no way to do this save Immobilize. Here's a sample of our new Viscid Glob spell, which uses this method, and which radically slows the target while they are affected:

#include "hg_inc"
#include "ac_spell_inc"

void CheckGlobMoveRate(object oTarget, int nDC, effect eEff, int nCount = 1) {

    if (!GetIsObjectValid(oTarget))
        return;

    int nRate = GetLocalInt(oTarget, "BaseMoveRate");
    if (!GetHasSpecificEffect(eEff, oTarget)) {

        SetMovementRate(oTarget, nRate);
        return;

    } else if (!(nCount%3)) {

        nDC -= 5;
        if (GetSkillCheckResult(SKILL_DISCIPLINE, oTarget, nDC) <= 0) {
            RemoveEffect(oTarget, eEff);
            SetMovementRate(oTarget, nRate);
            return;
        }
    }

    nCount++;

    DelayCommand(6.0, CheckGlobMoveRate(oTarget, nDC, eEff, nCount));
}

void ApplyNPCMovementRateChange(object oTarget, int nMoveRate) {
    int nBaseRate = GetLocalInt(oTarget, "BaseMoveRate");
    if (!nBaseRate) {
        nBaseRate = GetMovementRate(oTarget);
        SetLocalInt(oTarget, "BaseMoveRate", nBaseRate);
    }
    SetMovementRate(oTarget, nMoveRate);
}

void main() {
    struct SpellInfo si = GetSpellInfo();
    if (si.id < 0)
        return;

    si.dc = si.clevel*2;
    si.dc = (si.dc > 120 ? 120 : si.dc);

    float fDur = MetaDuration(si, si.clevel / 2, DURATION_IN_ROUNDS);

    if (GetIsSpellTarget(si)) {
        SignalEvent(si.target, EventSpellCastAt(si.caster, si.id));

        if (!GetSpellResisted(si)                                           &&
            !GetIsImmune(si.target, IMMUNITY_TYPE_MOVEMENT_SPEED_DECREASE)  &&
            GetSkillCheckResult(SKILL_DISCIPLINE, si.target, si.dc) <= 0) {

            ApplyVisualToObject(VFX_FNF_GAS_EXPLOSION_ACID, si.target);
            effect eLink = EffectSpellImmunity(HGSPELL_UNUSED);
            eLink = EffectLinkEffects(EffectVisualEffect(CEPVFX_AOE_FOG_STINK), eLink);
            SetEffectSpellId(eLink, HGSPELL_VISCID_GLOB);


            if (GetIsPC(si.target))  {
                ApplyEffectToObject(DURATION_TYPE_TEMPORARY, eLink, si.target, fDur);
                RecalculateMovementRate(si.target);
            } else {
                if (!GetHasSpellEffect(si.id, si.target)) {
                    //change this to a Recalc analogue if we add a second rate setter
                    ApplyEffectToObject(DURATION_TYPE_TEMPORARY, eLink, si.target, fDur);
                    ApplyNPCMovementRateChange(si.target, MOVEMENT_RATE_GLACIAL);
                    AssignCommand(GetArea(si.target), DelayCommand(6.0, CheckGlobMoveRate(si.target, si.dc, eLink)));
                } else  //block double application to prevent dur bugging
                    FloatingTextStringOnCreature("Only one Viscid Glob may be put on a creature at once!", si.caster, FALSE);
            }
        }
    }
}

Well you can add a line to appearance.2da with the immobile speed "NOMOVE" used instead and then use the script SetAppearance() to immobilize.  But as has previously been said, speed of 0.0 itself has problems in allowing NPC to make use of their AI effectively, just like EffectCutsceneImmobility().

Here are some alternatives to look at:
Defensive Stance (does not work with ranged weapons or spell casting).
Define a new movement speed (such 0.01) that is slightly faster than immobility.

We use movespeed GLACIAL, rather than immobilizing them. From our (modified) creaturespeed.2da:

That is PRECISELY why I suggested this approach. The very same you yourself suggest in your last sentence. Did you not read my post?

You didn't specificly say you ADDED a line to creaturespeed.2da.  My assumption was that you reset the speed to a previously existing line.  But you did say that this can be only achieved through NWNX, and I did mention that adding lines to appearance.2da would allow SetCreatureAppearance() to make use of the speeds defined there (even for extra lines added to creaturespeed.2da).  My post was there to show that there is a non-NWNX alternative, not to say that your method doesn't work or has problems.

No, I didn't. It's obvious from the code, which Sets moverate to a value not found in nwscript. I also made it explicit that it 'radically slows' the target, rather than immobilizing it, which renders your expressed concerns about this technique completely irrelevant. If you're going to reply to my posts, please take the time to read them. Doing otherwise wastes both our time and risks confusing the issue for the OP.

Since you want to throw down the guantlet, tell me where I interpreted that your glacial constant couldn't possibly mean very slow movement with run disabled.  You have already told me that I have interpreted your words specifically to mean immobile speed.  Show me where I said that.

Lolz, that was my response to that post as well. Fallen, here's the part of your where you offer a critique of my suggestion with no apparent awareness that I'm suggesting setting a very slow, rather than immobile movement speed, despite my having made that abundantly clear in my post:

At no point did I suggest setting a speed of 0.0, making that a pretty bizarre nonsequitor at best. If you actually took the time to read my post and reply to it, without grasping that concept, I can only suggest you avoid future remark on my posts, as you simply won't be able to add anything useful to the conversation. If you simply skimmed it, as I suspect, then I can only repeat my above suggestion - be a little more attentive to what you're replying to, in order to save everyone some pointless typing.

0.0 is the speed of "NOMOVE" from appearance.2da which was in the prior sentence.  I don't see how you are getting it to refer to the glacial constant which I did not mention at all.

[Buddywarrior]

Is it possible to add glacial to the appearance.2da and call it without nxnx (or with basic nwn +cep)?

[WhiZard]

Yes, you first need to add it to creaturespeed.2da and under the"2DAName" column set the string you wish to use in appearance.2da to call that row in creaturespeed.2da.

Very interesting, I found a fix using my custom scaling function that I adding to HR base. By adding in all the invisible types again into the apperance.2da with there default movement as NOMOVE with my function it will scale them. All you have to do is call the function HR_ScaleCreature(object oCreature,int iScale, int iImmobile); just set scale to 10 this will not adjust the size of the creature but will make them immobile and their AI will function. I did this because I wanted to scale in spawn and it need for plants so they can still do their special abilities/spells. I'm testing it now and seem to be good so far. Does not work with parts creatures but you prob. already know that.

[Zarathustra217]

Why not use EffectEntangle?

[ffbj]

A while back when the original statue scripts came out, statues before there where statues, you could put those scripts on, a suit of armor for example, and have them immobile but they would still fight, if attacked or hostile.
Or like Zarathustra said something like a spell-like effect without the ensuing visual effects. I was thinking of that encased in rock spell from the waist down.  So your own particular root effect.
Probably different ways to do it.

Because it will give negative AC and attack penalty oh and I think there a concentration check add (this is according to the lex.) and it cause the AI not to cast spell just like cutsceneimmobile

[Zarathustra217]

You could easily compensate for the AC and AB penalty. And the lexicon says exactly the opposite:
"In P&P D&D, it is meant to add an additional concentration check for casting spells (DC: 15) but this is not in NwN"

In the end, the AC and AB penalty would make sense though.

Lexicon (whatever version quoted) is wrong on that.  There is a DC 15 concentration check, but it is not displayed.  The HotU manual states a DC of 15 + spell level, however the DC is a static 15.
