I can't say anything without knowing content of file supposed to read. Are you
sure it was created corrently ? Have you tried debugging readed values ? Can I
see writing part ?

I have read the file manually and all values appear to be in the correct
places.

>Have you tried debugging readed values ?

Yes, that is how I found the problem of the #read part skipping lines.

>Can I see writing part ?

Certainly p.t.s.f  one thread down from the other post

Thanks

Ok. Probably your fault. Please reread my first post I posted in this thread
and note what I said about separating items in file. Then open your
documentation and look there again and read the same subject (in current 3.5
documentation it is in bottom part of chapter 6.2.3.4).

Have the first value written in your file indicate whether this is the
data has been already generated... might even work <g>

Try #if (clock=initial_clock) ...

Yeah I did try that but it still would not work in some of the ways I
wanted.

However I have now cracked the problem using another method.

Thanks for the suggestion though.

Dave.

Actually #if (frame_number=initial_frame)... works slightly better than my
previous way.  Slight question: what is wrong with the other/this method?

Post a reply to this message

There is nothing wrong with your methods at all.

Its just to get round the problem I set up 2 scene files.

An initial scene (for setting all of my initial particle parameters etc)

An the main scene (which the animation ini file calls)

I have just found it easier doing it this way.
