Jiggle camera mod

[airdoc]

Hi,

 

This is a modification of the Camera Jiggle function, that produces a more realistic shake than the current one.

 

To use it, open the View.Lua file, located at C:\Users\[yourname]\Saved Games\DCS\Config\View directory, and replace the current Camera Jiggle Function with the following lines:

 

function CameraJiggle(t,rnd1,rnd2,rnd3) ---modded

local rotX, rotY, rotZ, ampx, ampy, ampz1, ampz2, durz, freqz

ampx=0.022 ---x axis shake amplitude

ampy=0.022 ---y axis shake amplitude

ampz1=0.015 ---z axis shake amplitude for the equations of the first part of rotZ

ampz2=0.035 --- z axis shake amplitude, for the intervening pulses, defined by the last part rotz equations, starting with math.floor(math.abs(...

durz=0.1 ---duration of pulses for z axis

freqz=60 ---frequency of vibrations during the pulse for z axis

rotX = ampx*math.sin(55.0 * (t - 2.0))- 2*ampx*math.sin(0.86 * (60*t+5))+1.5*ampx*math.sin(1.86 * (65*t+3))+3*ampx*math.sin(1.86 * (52*t+3))+2*ampx*math.sin(1.86 * (68*t+6));

rotY = ampy*math.sin(50.0 * (t - 5.0))- 0.52*ampy*math.sin(0.86 * (40*t+3))+0.01*ampy*math.sin(1.86 * (65*t+3))+0.45*ampy*math.sin(1.86 * (42*t+3))+0.4*ampy*math.sin(1.86 * (60*t+6));

rotZ = ampz1*math.sin(55.0 * (t - 2.0))- 0.80*ampz1*math.sin(0.86 * (70*t+5))+1.3*ampz1*math.sin(1.86 * (65*t+3))+1.8*ampz1*math.sin(1.86 * (62*t+3))+2*ampz1*math.sin(1.86 * (78*t+6))-1.8*ampz1*math.sin(1.2*(66*t+2))+math.floor(math.abs(math.sin(0.8*t)+2*durz))*math.sin(1.34*freqz*t)*ampz2+math.floor(math.abs(math.sin(0.2*t)+2*durz))*math.sin(1.5*freqz*t)*ampz2+math.floor(math.abs(math.sin(0.3*t)+2*durz))*math.sin(1.4*freqz*t)*0.875*ampz2+math.floor(math.abs(math.sin(0.05*t)+durz))*math.sin(1.68*freqz*t)*1.125*ampz2+math.floor(math.abs(math.sin(0.03*t)+1.2*durz))*math.sin(1.48*freqz*t)*0.75*ampz2+math.floor(math.abs(math.sin(0.025*t)+3.4*durz))*math.sin(1.36*freqz*t)*ampz2;

return rotX, rotY, rotZ

end

 

 

For better results, set the Camera Float dX, dY, dZ parameters, that are located below the jiggle function, to 0.

 

Backup your View.lua file before doing any modifications.

 

You can experiment with the ampx, ampy, ampz1, ampz2, freqz, durz parameters in order to tail the camera shake according to your demands.

 

ampx, ampy and ampz1 are the main variables that define how large the shake is.

Ampz2, freqz and durz currently affect only z-axis shake, that has a different structure from the rest, with intervening pulses. Ampz2, freqz and durz define the amplitude, frequency (the pulse vibration frequency and not how often the pulses appear), and duration of pulses.

 

The numbers given are for an average shake. It can be used for in-cockpit view, shift+F4 (nose or wing) view or other views. They are meant for simulating aerodynamic vibrations and not camera shakes for airshow cameras.

 

Setting ampz1 and ampz2 to zero, will produce a softer shake, that may be better for continuous in-cockpit view.

Thanks. I'm always interested in jiggle camera feature.

I'll try this code.

 

Thank you.

[Vespa]

Thanks a lot.Me too I'm interested in this feature

Edit: sorry for the silly question...in that path on my PC I can just find a server.lua file.

How to use the function above? Do I need to create a new file?

Thanks

• Browse "..\DCS World\Config\View\" folder,
  
• copy View.lua and
  
• paste it into "C:\Users\{username}\Saved Games\DCS\Config\View\" folder.

[Vespa]

Thx a lot Devrmi ;)

[uboats]

Is there any way to enable jiggle by default (no need press the shortcut in game)?

[Devrim]

We looked for it very long time, Uboats, but no luck unfortunately... :\

 

It may be hard coded and, got no answer due to FPS issue maybe. If it was default, other users would probably complaint, "Please! No jiggle by default!". ;)

You 're welcome Devrim and Vespa.

 

If you come up with specific combinations of numbers for the variables, don't hesitate to post them here.

 

With this code, it is a lot easier than the stock one to experiment and come up with different results.

 

For the time being, I haven't introduced other variables, in order to keep the code as simple as possible. If people are interested, the modification of other axes (x and y) for introduction of pulses and the addition of a general shake frequency variable shouldn't be hard to implement.

I mean something like an option (not key press), or something like boolean variable that can be set in the autoexec.cfg file.

return rotX, rotY, rotZ

end

 

 

For better results, set the Camera Float dX, dY, dZ parameters, that are located below the jiggle function, to 0.

 

Backup your View.lua file before doing any modifications.

I will try this mod later today because the current jiggle feels over-done.

 

Is it possible to have your jiggle mod turned on by default instead of after tapping the jiggle key 3 or 4 times?

 

EDIT:

 

From analysing the code I gather the jiggle is fully mathematically pre-scripted and is not affected by actual factors like air pressure, turbulence, AoA, etc. Am I right?

Hi Jaypee

 

As far as I know, one has to use the keys to enable jiggle. Its function is tied to the camera float, so when you enable jiggle, you always get a float as well, that's why I recommended to set the float parameters to zero.

 

As you noticed, jiggle parameters are prescripted (like the stock ones). I 've looked around for ways to introduced G or AoA - dependent jiggle, but wasn't able to find the functions in the lua file.

 

EDIT : if you feel that stock jiggle is overdone, you may find this jiggle mod excessive as well. In that case, try reducing the ampx, ampy, ampz1, ampz2 parameters by 30-50% to see if the results match your expectations.

 

cheers
