Local copy updated, thanks.

[argent77]

BG:EE and BG2:EE added additional fields to GAM resources:

Offset    Size          Description
0x0080    4 (dword)     Zoom level (Default: 100, lower values zoom in, higher values zoom out)
0x0084    8 (resref)    Random encounter area (set by script action ForceRandomEncounter(S:Area*))

[Jarno Mikkola]

BG:EE and BG2:EE added additional fields to GAM resources:

 Offset	Size		  Description
0x0080	4 (dword)	 Zoom level (Default: 100, lower values zoom in, higher values zoom out)
0x0084	8 (resref)	Random encounter area (set by script action ForceRandomEncounter(S:Area*)) 

Would this techically mean that were we to go and manipulate the value in the .gam file, we could zoom in and out on PC ? Cause there's no hipster to do so currently. Hipster, adjustment device, whatever.

Of course only in an EE games. That goes without saying.

[argent77]

That's right, but you are limited to the range 55..114 (and 0 which is the same as 100). Anything else will be adjusted by the games automatically.

 

[Ardanis]

Zoom function is controlled by mouse wheel.

[Jarno Mikkola]

Zoom function is controlled by mouse wheel.

Seems to work...

Is there a reset default zoom key ? And a silly question, what if I don't have a mouse wheel ?

[argent77]

Zoom function is controlled by mouse wheel.

And by the +/- keys on the keyboard (which is annoying as the original BG(2) used one of those keys for selecting all party members).

 

Is there a reset default zoom key ?

Editing the GAM files directly is the only way (I know of) to reset the zoom level to 100% without resorting to trial & error.

[argent77]

IWD:EE added another field to the GAM format:

Offset    Size          Description
0x008c    8 (resref)    Current worldmap (set by script action SetWorldmap(S:Worlmap*))

[Avenger]

Actually, there are more new fields:

0084h Queued encounter

008ch Worldmap

0094h <Unused 8 bytes in IWDEE>

009ch Familiar owner

00a0h <Unused 5x4 bytes in IWDEE>

(Familiar owner is the PC's portrait index who first summoned a familiar)
