Hi,

bei Gothic 2 gibt es diesen Slow Motion Effekt wenn man Sumpfkraut oder schwarzes Erz benutzt. Ich könnte diesen Effekt für Gothic 1 gut gebrauchen. Er lässt sich nämlich auf für ein Zeitraffer einsetzen. Die Frage ist, ob die alte Engine das schon bringt?

In Gothic 2 steht in VisualFxInst.d

INSTANCE SLOW_TIME(CFx_Base_Proto)
{
	// userstring 0: world  time scaler
	// userstring 1: player time scaler
 	visName_S      		= "time.slw";
 	userString[0]     	= "0.5";
 	userString[1]     	= "0.5";
	emFXLifeSpan    	= 30;						// achtung, zeitdauer ist hier skaliert mit dem time scaler
	emFXTriggerDelay	= 6;						// achtung, zeitdauer ist hier skaliert mit dem time scaler
	emFXCreate_S		= "SLOW_TIME_CHILD";
	emTrjOriginNode 	= "BIP01";
};


INSTANCE SLOW_TIME_CHILD(CFx_Base_Proto)
{
	// userstring 0: world  time scaler
	// userstring 1: player time scaler
 	visName_S      		= "SMOKE_JOINT_SLOW_TIME";
	emFXTriggerDelay	= 6;						// achtung, zeitdauer ist hier skaliert mit dem time scaler
 	sfxid      			= "MFX_Telekinesis_StartInvest";
 	sfxisambient     	= 1;
	emFXCreate_S		= "SLOW_TIME_CHILD2";
};


INSTANCE SLOW_TIME_CHILD2(CFx_Base_Proto)
{
	// userstring 0: world  time scaler
	// userstring 1: player time scaler
	emFXTriggerDelay	= 6;						// achtung, zeitdauer ist hier skaliert mit dem time scaler
	emFXLifeSpan    	= 30;						// achtung, zeitdauer ist hier skaliert mit dem time scaler
 	visName_S      		= "morph.fov";
 	userString[0]     	= "0.8";
 	userString[1]     	= "1.0";
 	userString[2]		= "120";
 	userString[3]		= "90";
};

In PfxInstMagic.d steht

INSTANCE SMOKE_JOINT_SLOW_TIME (C_PARTICLEFX)
{
     ppsvalue = 300;
     ppsscalekeys_s = "1 1 1";
     ppsissmooth = 1;

     shpdistribtype_s = "UNIFORM";
     shpdim_s = "10";
     shpmeshrender_b = 1;
     shpscalekeys_s = "1";
     shpscaleissmooth = 1;
     dirmode_s = "RAND";
     dirfor_s = "OBJECT";
     dirmodetargetfor_s = "OBJECT";
     dirmodetargetpos_s = "0 0 0";
     dirangleheadvar = 180;
     dirangleelevvar = 180;
     velavg = 0.00999999978;
     lsppartavg = 2000;
     lsppartvar = 100;
     flygravity_s = "0 0 0";
     visname_s = "HEAVENLIGHT.TGA";
     visorientation_s = "VELO3D";
     vistexanifps = 18;
     vistexaniislooping = 1;
     vistexcolorstart_s = "0 255 100";
     vistexcolorend_s = "255 0 100";
     vissizestart_s = "2 50";
     vissizeendscale = 30;
     visalphafunc_s = "ADD";
     visalphastart = 150;
     useemittersfor = 1;
};

In Gothic 1 habe ich den Code in VisualFxInst.d bzw. in PfXMagic.d kopiert. Die roten Stellen habe ich wegen unmittelbarer Fehlermeldungen auskommentiert. Der übliche Aufruf geschieht dann mit

			Wld_PlayEffect("SLOW_MOTION", self, self, 0, 0, 0, FALSE);

Leider passiert absolut nichts. Liegt das an der Engine, oder lässt sich da etwas machen?

Edit: Übrigens könnte man in Mods den Slow-Motion-Effekt dramaturgisch verwerten, beim Tod von Bossgegnern oder wenn der Held stirbt. Ist nur so eine Idee. Mir geht es wie gesagt um Zeitraffer.

Edit2: Die Sache hat sich im Wesentlichen erledigt. Ich habe eine andere Lösung gefunden.

Hi, wie hast du es geschafft, dieses Problem zu lösen?

[Cryp18Struct]

Walter Fabers letzter post war in 2013, ist unwahrscheinlich das er diesen thread sieht.

Sektenspinner hatte mal eine Skriptlösung gepostet um Zeit schneller oder langsamer verstreichen zu lassen, möglicherweise funktioniert das auch in Gothic 1:
https://forum.worldofplayers.de/foru...1#post14841249

[Orc Hunter UA]

Mit dieser Funktion können Sie nur die Geschwindigkeit der Änderung der Tageszeit ändern, aber die Geschwindigkeit der Zeichen ändert sich nicht. Ich muss die Zeit verlangsamen, wenn ich in Gothic 2 einen Bogner rauche. Ich bin auch an der Wirkung interessiert, den Bildschirm zu verzerren, der beim Tauchen und im zweiten Gothic beim Rauchen und Kommunizieren mit den Suchenden gespielt wird.

[Cryp18Struct]

Tut mir leid das ich dir eine komplett unbrauchbare Antwort gegeben habe, ich hatte den post falsch verstanden.

In Gothic 1 funktioniert der cheat (F2):

ztimer multiplier 0.2

Es gibt also definitiv die Möglichkeit das Spiel in slow motion ablaufen zu lassen.
Wo man das skriptseitig aktivieren und deaktivieren könnte weiß ich nicht.


I am sorry for giving you a completely unhelpful answer, i misunderstood that post.
In Gothic 1 the cheat(F2):

ztimer multiplier 0.2

does work.
So there definitely is a way to have the game play out in slow motion.
How to activate and deactivate this with script commands, i do not know.

edit:
Ikarus Engineclasses:

class zCTimer {
    var int factorMotion;        //zREAL        //nicht zu klein machen. Sonst: Freeze bei hoher Framerate!

maybe this?

[F a w k e s]

This would be something that's definitely interesting for me as well
Besides 'zTimer multiplier f' console command there are 3 cheat codes, which are also affecting game time. First 2 are basically doing same thing as zTimer multiplier. You can activate these same way as Marvin, hit B and type:

SOUTHPARK - everything will be fast
CLERKS - everything will be slow

But here comes something I would like to understand how it works within engine:
HIGHLANDER - NPC in your focus becomes faster than any other NPC !

I would like to use same principle - but instead of speeding up NPC I would like to slow it down. So player would be able to freeze NPC in time by a spell for example.

You can play around with this to get some interesting behavior:

B MARVIN

Press 'O' to control any NPC

Turn your controlled NPC so it would have HERO in focus

B HIGHLANDER - this will speed up hero

Press 'O' to control HERO

F2 console command zTimer Multiplier 0.5 - hero is now moving a little bit faster than normally, while every other NPC in the world is moving 1/2 normal speed

But question is - how does this work, is someone able to find out what this HIGHLANDER cheat code is doing using IDA ?
(I've never used it actually )

[NicoDE]

HIGHLANDER: focus->GetModel()->SetTimeScale(3.0f);
EOWYN: focus->GetModel()->SetTimeScale(0.4f);

SOUTHPARK: ztimer.SetMotionFactor(3.0f);
CLERKS: ztimer.SetMotionFactor(0.4f);

ZTIMER MULTIPLIER: ztimer.SetMotionFactor(PickWord(3))
ZTIMER REALTIME: ztimer.SetMotionFactor(1.0f)

oCVisualFX::SetVisualByString (G2!): if (visName_S.Search(".SLW")!=-1) { ztimer.SetMotionFactor(userString[0]); origin->GetModel()->SetTimeScale(userString[1] / ztimer.GetMotionFactor()) }

Ich gehe aber davon aus, dass einiges davon nicht konsistent in G1 funktionieren wird (z.B. Spieler benutzt MOB), da die korrekte Behandlung der zeitskalierenden Effekte erst in G2 implementiert wurde.

Hi NicoDE!
Thank you for your reply

I was able to use engine function SetMotionFactor to get same effect as Console command ztimer Multiplier f:
edit: seems to be not working when called from Dialog!

//Gothic 1

//Beware - Ikarus 1.2 has an incorrect address MEMINT_zTimer_Address - Thank you mud-freak for pointing this out !

//008CF1E8  .data     Debug data           ?ztimer@@3VzCTimer@@A
const int MEMINT_zTimer_Address = 9236968; //0x8CF1E8

//00607640  .text     Debug data           ?SetMotionFactor@zCTimer@@QAEXM@Z
const int zCTimer__SetMotionFactor = 6321728;

FUNC VOID zCTimer_SetMotionFactor (var int f)
{
    CALL_IntParam (f);
    CALL__thiscall (MEMINT_zTimer_Address, zCTimer__SetMotionFactor);
};

//This will have same affect as console command zTimer Multiplier 0.5
zCTimer_SetMotionFactor (divf (mkf (5), mkf (10)));

However I was not that lucky with piece which I am mostly interested in - HIGHLANDER emulation.
I couldn't find an address of this function SetTimeScale

I am using this list of addresses I found a loooong time ago while googling - it might be it is incomplete
http://delfcode.ru/_fr/13/GothicMod.txt

Would you have any advice for me ? Thank you

[NicoDE]

I couldn't find an address of this function SetTimeScale

There seems to be no one (at least in the Player-Kit 1.08k).
Very likely because the getter/setter is implemented in the header and has always been inlined.
Like in HandleResultString:

zCModel.timeScale directly follows the model flags (isVisible, isFlying, ...). For 2.6 only the field offset differs:

Hi NicoDE,
Brilliant stuff! Thank you
To be honest ... I have no idea what above assembler functions are doing lol, but kind of guessed that this is what I have to do:

FUNC INT oCNPC_GetModel (var C_NPC npc)
{
    //00695300  .text     Debug data           ?GetModel@oCNpc@@QAEPAVzCModel@@XZ
    const int oCNPC__GetModel = 6902528;

    CALL__Thiscall(_@(npc), oCNPC__GetModel);
    
    return CALL_RetValAsInt();
};

FUNC VOID NPC_SetTimeScale (var C_NPC npc, var int f)
{
    var int ptr; ptr = oCNPC_GetModel (npc);
    
    //1D0h = 464
    MEM_WriteInt (ptr + 464, f);
};

var int f;
f = divf (mkf (4), mkf (10));

var C_NPC Diego;
Diego = Hlp_GetNPC (PC_THIEF);

NPC_SetTimeScale (Diego, f);

And it works!!

Combination of both - everyone is slow, player slightly slower than normally ... however behavior is super weird, I am able to run away from camera !

FUNC VOID Use_Joint ()
{
    if (NPC_IsPlayer (self) == TRUE)
    {
        var int f;
        f = divf (mkf (2), mkf (10)); //Slow down everything 5 times
        zCTimer_SetMotionFactor (f);
        
        f = mkf (5); //Increase hero's speed 5 times
        NPC_SetTimeScale (hero, f);
    };
};

Thank you for the video!
I think the strange camera is somewhat appropriate for being high on swampweed

Hi NicoDE !
I am sorry to bother you again
Trying to figure out how to fix camera problem - and found this engine function oCGame__SwitchCamToNextNpc.
This one seems to be nicely switching camera to NPC - however I don't have any control over it - I cannot specify to which NPC camera switches - and here I would like to ask you for a favor

Can you please share with me, how this works in background?

Ideally I would like to create function which would allow me simply to switch camera to any NPC. (don't want to ask you explicitly for creating such function, however I would not mind at all if you would create it ) I was thinking if you can point me to right direction I could maybe manage it myself. (Sometimes I like to experiment with all these beautiful functions, for some reason I like to just call functions even though I have no idea what they are suppose to do - I know it's weird lol)

Hello folks,
I was almost able to achieve what I was looking for:

• Hero's turning speed is increased.
• Camera moves with hero - it's pinpointed to his back. However if camera crashes with any obstacle - it is turning like crazy.
