Could this feature be incorporated somehow! (Pro Edition!!)

Many Thx.

You can change the demo names in the Options dialog. But they won't stick when you restart the demo. I'll have to think of a way to do this. Perhaps in demo mode, GooPs could look for a file with the vehicle name (<Name>.nme) and use that for the track data if it exists.

You can set the <RotateMinimum> to whatever speed you like in autozoom.cfg.

To set the RotateMinimum parameter add this line to your AutoZoom.cfg file:

<RotateMinimum>.5</RotateMinimum> ; don’t auto-rotate at speeds below .5 mph.

Hi David,

Under Label Text, the current display options include NAME, HOST, TIME, SPD, ALT.
Can this be updated to include HEADING.

Thx.

In number 2 - do you mean add "rotation" to the autozoom.cfg table?

Yes indeed! The Autoview Rotate Perspective can be controlled through a parameter in the autozoom.cfg table for different speed ranges.

Thx.

I think I must be using an old version because I don't have that autozoom.cfg file....

David,

May I suggest a possible solution whereby GooPs look for the following file extensions in the current directory;
<Name1>@demo.nme, <Name2>@demo.nme,.... <NameN>@demo.nme

If these files exist, they should take precedence over the default demo, and be played.

The corresponding Names (<Name1>, <Name2>,...<NameN>) should appear in the Options Dialog.

Mnay Thx.

You can just create it yourself with a text editor. Be sure to place it in the same place as the GooPs executable.

Hi David,

Need your help with editing <Name>play.nme file. I did manage to manipulate the NMEA data sentences, but when playing back the file the changes were not reflected.
I believe the problem may be with the CHECKSUM which was not updated (recomputed) after changing the data in the NMEA sentence.
Does Goops use the CHECKSUM to validate the NMEA sentence?

Thx.

Hi Abeh,

Yes, GooPs uses the checksum to validate the sentence. The date/time stamps must also be in chronological order (can't go backward in time). If you want I can put in code to ignore the checkum if it is a special value (say zero).

Hi David,

Thanks for the clarification!

I changed the Altitude parameter in the NMEA sentence, without recomputing the CHECKSUM, but this value was ignored on playback.

Is there a quick way (algorithm) to generate the new CHECKSUM.

Thx.

Abeh,

Here is a beta that will ignore the checksum if it is zero.
http://goopstechnologies.com/beta/GooPsPro2_3Beta.exe

Let me know if you still need the checksum algorithm, or just google "nmea checksum algorithm".

Abeh · 10-26-2007, 12:45 AM

Hi David,

Many thanks for providing a pointer to the new beta.

Setting the Cheksum to Zero did the trick!

However, it would be nice to be able to compute the checksum so that it may be validated.

Thx.

Here's the GooPs code:
int calcCheckSum(char *s)
{
if (!s) return 0;
int checksum=s[1];
int len = strlen(s);
for (int i = 2; i <len;++i)
checksum^=s[i];
return checksum;
}

Hi David,

Label Text display options, NAME, HOST, TIME, SPD, ALT, HDG, are currently displayed at the cursor origin (Centre Justification, I believe!), and tend to clutter (overlay) the underlying cursor image or 3-D model.

It would be preferable to offset the Label Text so that the cursor, represented by an image or 3-D model is more clearly visible. The Offset should take into account any Cursor Scaling and or Rotation.

Food for thought!

Thanks, once again

Hi David,

Making the TimeStamp Interval user definable would be a nice added feature.

Thx.
