iwd2 area unknowns

[Avenger]

These are not really unknown, just missed from IESDP

 

0xd4 - map note offset

0xd8 - map note count

Actually, this flag exists in BG2 too.

 

In region flag: 0x20 - Active only in tutorial state.

 

iwd2 has no 'no npc may pass this region' flag. Which is normally at 0x200

Instead, iwd2 has the 'alternative point' flag in this place (which is normally at 0x400).

I hate when they do this

The creature header (iwd2):

00000000 _area_creature  struc ; (sizeof=0x110)
00000000 label		   varname ?
00000020 posX			dw ?
00000022 posY			dw ?

0000008C size			dd ?
00000090 scr_special1	resref ?
00000098 field_98		dd 30 dup(?)

 

Notable changes:

the saved first char of the resref is not a word (at 0x2e)

correct name for scripts

special1 script is saved in the area (only in iwd2)

From the creature area flags the following bits are set in the creature's mc_flags:

2 - seen party (0x10000)

4 - invulnerable (0x20000)

8 - enabled (0x8000)

You can see the mc_flag definitions in creareafl.ids

 

0x2f does something, but i don't know what, if it has the wrong value, the creature is not loaded.

It is compared to the area difficulty, so i guess, it is also a difficulty level (bitfield).

Creature enabled on:

1 - area difficulty 1

2 - area difficulty 2

4 - area difficulty 3
