Well I am back to this project. Let me start from the beginning I guess. I wanted to use an object rather than a matrix as terrain.

Reason: Physx

So I created a seperate bit of code to create 4 plains. I then converted them to memblock so I could see what I was facing. I saved the memblock line by line to a text file and this is what I am stuck looking at:

+ Code Snippet

Now, so far, I have narrowed it down to a vertex looking like this inside all that:

9.99999809265
9.99999809265
2
-8.7422769468e-008
0
-0.999999940395
1
0

I know lines 1, 2 and 6 above are the XYZ data since I can move the vertices (even figured out which vertex is where).

My question is what on Earth is everything else? And what is with the extra 0 at the end of the object data?

Is there documentation labeling the individual lines in FVF formats? I'm getting different results when I alter the variables as you've shown. Does it magically vary? DX has got me lost on this one. Here's what I've got. Sorry its so sloppy. It was gonna be a quick learn example just for myself so I just slapped it together as I went.

	dbDeleteMesh ( 3 );
	dbDeleteMemblock ( 3 );
	dbDeleteObject ( 4 );
	dbDeleteMesh ( 4 );
	dbDeleteMemblock ( 4 );

	for ( y = 6; y < 17; y++ ){
		dbDeleteObject ( y );
	}

	// and now everything is ready to return back to Windows
	return;
}

It creates a txt file on the desktop with the memblock output of two of the objects. You'll need to update the folder path.

Thanks for your help on this issue.

I don't have dark gdk installed so i can't try your code. What exactly is different compared to what i described in my previous post?

Here is a great memblock code snippet for use in dark basic pro. After you look at it maybe some thing become clearer to you.

Thanks for the expedient answer. The difference is I get it to move when I do it like this:

9.99999809265 position x
9.99999809265 position y
2
-8.7422769468e-008
0
-0.999999940395 position z
1
0

I'm not sure if that's the right order but those are my 3 positioning variables... not sure why its different is all.

there's something wrong with the dword positions you use to read values from memblock. Check my snippet i posted in previous post to see how to read those values corectly

OMG wow I feel dumb. I was only modifying the z position for each vertex. You were 100% correct. I see it all now. WOW! I'm the special kid...
