Jerky Attached Camera Help?

[TymC 10]

Hi guys! Hope you can help me, I've been using granQ's "Cam Scenes" for tracking vehicles, but when I try and track vehicles which are moving too fast (Jets) the camera jerks. It zooms in close then pops back ever half a second or so. This is the script; I was wondering if anyone could help me fix the problem? Cheers! (I have looked and couldn't find too much)

Start with the following code

my_Camera = [car1,1000,"chase side"] execVM "cam_scenes.sqf";

object = name of any vehicle/object ingame that you want the camera to focus on.

duration, in seconds how long do you want the scene to be.

"type", the style you want. Replace with any of the following:

"zoom"

"zoom top"

"chase"

"chase side"

"chase angle"

"fly in"

"fly around"

"static"

On occasion, I have trouble with camera stuttering too. I use sqs and I think your example is sqf which I know very little about.

Recently tried this in sqs when stuttering camera occurred.

Every camera block in sqs contains the line _camera camCommit 0

Not sure but _cam camCommitPrepared 0; might be the same thing in your example?

Anyways for me, in _camera camCommit 0 the zero means the camera will move to its new location instantly.

So in my case to try to get rid of camera stutter I changed the zero to a one.

This helped. Only tried this today by trial and error so it may not be foolproof.

In one loop block I only had to change the zero to .1. In another I had to change the 0 to a 1 to eliminate the camera stutter.

I eliminated it another way or at least I think I have.

first I changed the way you set the duration as I needed to adjust sleep as well

_duration = time + (_this select 1);

then a few small changes in the camera loop

//example chase side
if (_type == "chase side") then
{
_cam = "camera" camcreate [0,0,0];
_cam cameraeffect ["internal", "back"];
_cam camPrepareFOV 0.700;

while {_duration > time} do
{
_cam camPrepareTarget _object;
_cam camPrepareRelPos [1,0,1.4];
_cam camCommitPrepared 0;
sleep 0.005;
};
_cam cameraeffect ["terminate", "back"];
camdestroy _cam;
};
