Camera Zoom in Turret View

You have to make from constant a dynamic parameter… If you want dynamic zoom in turret view.

[Cockpit]
mesh = cockpits\liberty\models\li_freighter_cockpit.cmp 
int_brightness = 0.500000 
head_turn = 30, 120 

[CockpitCamera]

[TurretCamera]
tether = 0.000000, 20, ->230 <---- this constant
yaw_rotate_speed = 2.000000 
pitch_rotate_speed = 1.500000 
accel_speed = 5

[RearViewCamera]
view_position = 0.000000, 20.000000, 360.000000

Attached is a plugin to use the wheel (in Turret View only) to change the tether value mentioned above. It multiplies/divides by 1.5 each turn. (See TurretZoom.c for installation.)

Works very good thanks .
Can the zoom-in be increased ?

The value I’m changing is really only the camera position, so no, once it’s near zero, there’s nowhere else for it to go.

I think he means the speed at which you zoom in, though I may be wrong.

I think what he means (I tested this as well) is that you can only zoom out, not in. In order to see what is in front of you you have to actually zoom out, then rotate 180 degrees. Now you are looking at the ‘back’ of the object that is in front of you.

Great stuff as always adoxa. Is there a way to reverse the scroll? (or invert, if that’s the way you like to roll)

Thanks for the Tips

@Adoxa: thanks for the plug in, on ly in turret view s perfect for my use, cause with the limit 101 technique, arrow keys let me move in turret view for my BIG ships in asteroid fields

Thanks again to both of you for the help

Here’s an update that might do what you mean by zoom in, by switching to a negative z coord. Note that zooming in a lot plays havoc with the camera speed. I’ve also maxed it out at 500k.

@Bob: If by reverse/invert you mean swap the meaning of the wheel direction, then patch the DLL at 0x1009, 0x7D->0x7E and 0x107C, 0x7E->0x7D.

Thanks adoxa, that works much better.

and a short video…

Very good .
This is something completely new in Freelancer , an overview of whole system.
Thank you .

Unfortunately my experience with dll’s end at changing some simple data type stuff out of Limit Breaking 101.
I’ve got no idea how to do that.

Use hex editor .
I recommend 010 editor or HexWorkshop .
You have to search in hexadecimal the adress adoxa provided and at that adress is filled with some value that is also hexadecimal .
You only have to change that value at that adress from 7D to 7E and 7E to 7D .

hexplorer do the same job, and have a “matrix” theme (black/green) by default lol^^ (don’t forget to click on view/simple data types)

I dunno whether I broke it or I’m just missing something fundamental. xD

EDIT: Image wasn’t working for me, so made into a link. :S

Looks like you didn’t get the updated version.

facepalm
That’s a Bob mistake. >_>

Thanks.

Awesome work Adoxa, thx.

void Zoom( void )

What do i have to change for changing the max zoom from 500k to 50k and the value of zoom from 1.5 to 1.2 ?
Just wanted that ppl cannot zoom out too far and make zooming more “smooth”.

Seems i cannot find the correct hex values in the dll

Thx in advance

cheers
CURSOR

You’ll notice I got the distance wrong and actually used 500,000K, so that wouldn’t have helped.

002024, 0.666667f = zoom in factor (1/1.5)
00202C, 500e6f = max zoom out
00203C, 1.5f = zoom out factor
002040, -500e6f = max zoom in

Thx a lot Adoxa
