Some help modding the camera zoom values ?

[PepprmintButler]

Hello everyone,

 

EDIT : I found the answer to my own question. See next post for the solution.

 

I found what I think is the key to changing the min/max values or the camera zoom, but I'm stuck at modifying the bytecode because I can't recognize anything. Maybe someone with more experience with the bytecode can help ?

 

Relevant code is in XComGame.upk/XcomPresentationLayer.

noexport simulated function ZoomCameraScroll(bool bZoomIn, optional float Amount)
{
local float newZoom;

Amount = 0.10;
// End:0x4e Loop:False
if(bZoomIn)
{
	newZoom = CAMGetCurrentView().GetZoom() + Amount;
}
// End:0x83
else
{
	newZoom = CAMGetCurrentView().GetZoom() - Amount;
}
// End:0xa5 Loop:False
if(newZoom > 2.50)
{
	newZoom = 2.50;
}
// End:0xc7 Loop:False
if(newZoom < 1.00)
{
	newZoom = 1.00;
}
CAMGetCurrentView().SetZoom(newZoom);
}

Clearly this bounds the zoom values between 1.0 and 2.5.

 

File in the unpacked upk is XcomPresentationLayer/ZoomCameraScroll.function and has the following code :

 

C5 68 00 00 32 55 00 00 00 00 00 00 B0 68 00 00

00 00 00 00 00 00 00 00 B3 68 00 00 00 00 00 00

49 06 00 1E CD CC CC 3D 15 07 4E 00 2D 00 B3 68

40 07 C7 00 B0 00 B1 68 00 00 1E 00 00 80 3F 16

0F 00 B1 68 00 00 1E 00 00 80 3F 19 1B 35 0F 00

00 00 00 00 00 16 13 00 00 00 00 00 00 1B 3D 63

00 00 00 00 00 00 00 B1 68 00 00 16 04 0B 53 00

00 00 02 41 02 00 32 75 00 00 00 00 00 00

 

I can't recognize a thing in there. Can you guys do better ? I'd really like to zoom in more on my guys !

So here it is. It was simple : just look for the values (I was searching for operatings, none of which I found the bytecode for).

 

1.0 is 80 3F

2.5 is 20 40

 

After that it's simple :

C5 68 00 00 32 55 00 00 00 00 00 00 B0 68 00 00

00 00 00 00 00 00 00 00 B3 68 00 00 00 00 00 00

1C 01 00 00 02 26 00 00 F3 00 00 00 BF 00 00 00

49 06 00 1E CD CC CC 3D 15 07 4E 00 2D 00 B3 68

00 00 0F 00 B1 68 00 00 AE 19 1B 35 0F 00 00 00

00 00 00 16 0A 00 90 A0 00 00 00 1B 71 35 00 00

00 00 00 00 16 00 B2 68 00 00 16 06 83 00 0F 00

B1 68 00 00 AF 19 1B 35 0F 00 00 00 00 00 00 16

0A 00 90 A0 00 00 00 1B 71 35 00 00 00 00 00 00

16 00 B2 68 00 00 16 07 A5 00 B1 00 B1 68 00 00

1E 00 00 20 40 16 0F 00 B1 68 00 00 1E 00 00 20

40 07 C7 00 B0 00 B1 68 00 00 1E 00 00 80 3F 16

0F 00 B1 68 00 00 1E 00 00 80 3F 19 1B 35 0F 00

00 00 00 00 00 16 13 00 00 00 00 00 00 1B 3D 63

00 00 00 00 00 00 00 B1 68 00 00 16 04 0B 53 00

00 00 02 41 02 00 32 75 00 00 00 00 00 00

 

I changed these values to respectively 0.25 (80 3E) and 4.5 (90 40)

 

-> Wham, bam, thank you m'am !

Zooming at the usual max zoom 1.0

Zooming at 0.25

Zooming out at 4.5

I feel that zooming over 3.0 is pretty useless, 4.5 is probably a bit much.

 

Next up is free rotation :thumbsup:

Nice work! :thumbsup:

Hey, great work! I was wondering how to do that myself! :dance:

[Odie1974]

Yeah, nice find... I added this to my game files as well...

Now if only somebody could find how to get rid of that annoying bahavior when camera snaps by default to the soldier you select...

[miked79]

Great job peppermint!

I actually stumbled upon this last night! :) yay for us! hehehehe!

 

Update...

 

Figured out how to slowwwwwly rotate the camera. But the snag I have is that it resets itself after every 4 rotations. So I need to find out where that value is, and set it so it will rotate a full 360 around the slower paced camera yaws that I have.

Any help will be appreciated!

TILT... waht we need is camera tilt so we can see where were going!

[bokauk]

I've made a tool to configure the camera.

 

Free Camera Tool

 

I don't think there's much I can do about tilt at the moment though I'm afraid.

I may Kiss you anyway.... modding in progress..... :thumbsup:

 

(camera-snap is the bane of my life, no camera-snap is BLISS!)

 

actually, maybe not, cant get it to work.. moving to your thread on the tool

Hmm, I am using the tool and it is very handy :)

But I noticed that sometimes the camera does autocenter on soldiers and sometimes it does not...

 

Do you have any idea why it might be?
