So many new options and ugly prc workarounds to rewrite.
Thank you very much. |

What are the chances of getting an override for the events?
Don't you hate people who keep demanding more constantly?  |

Bad choice of words on my end, sorry about that.
I meant setting a bypass local var in the script so that the event doesn't take place at all.
E.g. the character never entering Stealth mode or not executing the attack. |

Yeah, thats the next step, didnt manage to do that in a working fashion. Stealthmode ended up getting stuck in stealthmode without being in stealthmode and attack can be avoided with AssignCommand( oPC, ClearAllActions( TRUE ) );.

Edit: nevermind, I solved it.
Ok, thread recycled.
I'm looking/trying to hook a nwn function or find a way to turn object ID(IE: ObjectToString) to the actual object since nwn uses the object ID rather then the actual objectpointer in some arrays, area list on module as an example.
I've been working on a memory editor plugin (Set/GetPointer/String/Int/word/byte, NewString/Int, Delete, etc) and so far I've managed to make functions such as Set/GetScriptEvent, SetTag, SetResRef, Set/GetLocalVariableInIndex, SetItemAppearance/Color/Part. So reason I want StringToObject is to read the area list on the module for a GetFirst/NextArea functionality.
I've tried calling some nwn functions CServerApp::GetObject(ulong) something, don't remember the address offhand. But it just causes the server to crash and I'm don't quite have the assembly skills to figure out why. Anyone willing to help?
P.S. What I got so far

Thank you very much for the memory editor, Terra
My C skills are way too rusty to figure out how to port anything to windows but with this I managed to figure out how to access and change the effects structs (SetEffectSpellId will be very useful for PRC scripts).
Thank you again! |

Of course.
I "proof of concept" script implementation using your SetPointer and SetInt functions which is a little clunky but works for now. I might write actual code to do this directly later.
Anyways:
Starting with NWNX_GetObjectPointer:
The offset for the pointer to the effects pointer array is 0xE8.
The pointer array holds the addresses to the individual effects.
The order is 1, n, n-1, n-2, ... Four effects applied in succession would be stored like this 1, 4, 3, 2. So the last effect applied will alway be the second one in the list; unless of course there is only 1 effect, then it's the first. This is probably standard array or linked list behaviour but I'm not sure.
[Edit]
So much for the order. Seems if they're applied within the same function one after the other the order is the same as returned by GetFirst-/GetNextEffect.
[/Edit]
I'm still trying to figure out if the number of effects is stored anywhere.
The offsets for the effect struct itself I took from CGameEffect.h (Thanks to all the linux people working on that):
| Code: |
struct CGameEffect_s {
uint32_t eff_id; /* 00 */
uint32_t field_04; /* 04 */
uint16_t eff_type; /* 08 */
uint16_t eff_dursubtype; /* 0A */
float eff_duration; /* 0C */
uint32_t eff_expire_day; /* 10 */
uint32_t eff_expire_time; /* 14 */
nwn_objid_t eff_creator; /* 18 */
int32_t eff_spellid; /* 1C */
uint32_t eff_is_exposed; /* 20 */
uint32_t eff_is_iconshown; /* 24 */
uint32_t field_28; /* 28 */
uint32_t eff_link_id1; /* 2C */
uint32_t eff_link_id2; /* 30 */
uint32_t eff_num_integers; /* 34 */
int32_t *eff_integers; /* 38 */
float eff_floats[4]; /* 3C */
CExoString eff_strings[6]; /* 40 */
nwn_objid_t eff_objects[4]; /* 44 */
uint32_t eff_skiponload; /* 48 */
};
|
To set the EffectSpellID for the first effect applied to oPC:
| Code: |
string sPCAddress = NWNX_GetObjectPointer(oPC);
int iPCAddress = NWNX_HexToInt(sPCAddress);
string sEffectArray = NWNX_IntToHex(iPCAddress + 0xE8);
WriteTimestampedLogEntry("Effect Array Address: "+sEffectArray);
NWNX_SetPointer(sEffectArray); //pointing to Effects Array Address
int nFirstEffectAddress = NWNX_GetInt();
WriteTimestampedLogEntry("First Effect Address: "+NWNX_IntToHex(nFirstEffectAddress));
NWNX_SetPointer(NWNX_IntToHex(nFirstEffectAddress)); //pointing to first effect Address
int nFirstEffect = NWNX_GetInt();
NWNX_SetPointer(NWNX_IntToHex(nFirstEffect)); //pointing to start of first effect struct
WriteTimestampedLogEntry("Start of First Effect: "+NWNX_IntToHex(NWNX_GetInt()));
int iSpellId = nFirstEffect + 0x1C;
NWNX_SetPointer(NWNX_IntToHex(iSpellId)); //pointing to Spell ID
NWNX_SetInt(113); // setting new spell id (Mass Haste)

Alright, I grabbed CNWSObject.h and CGameEffect.h and it seems to work quite nicely.
| Code: |
else if (strcmp(Request, "PRINTEFFECT") == 0) {
const CNWSObject *obj;
const CGameEffect *eff;
obj = (CNWSObject*)gameObject;
Log("ID: %08X\n", obj->obj_id);
Log("Eff: %08X\n", obj->obj_effects);
int i=0;
for (i=0; i< obj->obj_effects_len; i++) {
eff = obj->obj_effects[i];
if (eff == NULL) continue;
Log("Eff_id [%i]: %08X\t", i, eff->eff_id);
Log("Eff_Type [%i]: %08i\t", i, eff->eff_type);
Log("Eff_creator[%i]: %08X\n",i , eff->eff_creator);
}
}

Unfortunately when the player this is ran on exits the game the server crashes with a memory access violation  |

I think that should do it, most array has the length of the array next bytes after the address to the instances. So the length is at offset 0xEC (236). I did some testing and my test subjects always had 3 effects without any effects applied. Could have been some bioware default things but I'm unsure hence the -3 offsetting.

That's indeed it.
Apparently there are some effects applied that aren't quite "regular" - Racial Type, for example, or Speed Increase and Vision for DMs - which are not returned by GetFirst-/GetNextEffect.
I got the crashes fixed by simply deleting the localstring  and with a few lines of code I can now change the effect creator and spell id; and I guess everything else defined in the effects struct.
Sorry for hijacking your thread by the way. |

Its fine, I've been looking for ways to do that myself. Could I be so rude as to ask you to send the modified source to the mailaddress in my profile?
