Doing that:
for(i = 0; i < tableNo; i++)
Gives a Null Pointer Exception when the program is
run... I can't seem to shake it!
Any ideas?

You've created your array, be you actually create any objects in the array.
Object[] array = new Object[100];
Only creates space for 100 Objects, it creates no actual objects... you need
to do a
array[i] = new Object();
for each element.

Hi Kelvin,
I've tried your program and everything was OK.
So, I changed the program to reflect my case (you can find the files as

instanciated and made visible. If I close this wind

Morning all,
I've been looking at improving the performance of my old project as it looks like we
may be needing the code again for the next version of my friends PBeM game.
The basic context of the 3D components is to visualise information gathered on the
galaxy around you to aide your strate
If I understand you right,
you wanted an animated camera move ?
Then you should write your own Behaviour,
which uses the WakeUpOnElapsedFrames Criterion.
For every Frame you have to calculate the new camera position.
The Behaviour should stop running when the new position has been
reached.

Hi Mattijs !
It works better now. Thanks !

Yes, it is true, I have an older version of Detonator (28.32) but I

I found the problem in my code!
I had built up an array of objects:
Table[] table = new table[tableNo];
but I hadn't intialised them in the for loop! whoops!
Anyway the code now works and is as follows:
Table[] table = new Table[tableNo];
for(i = 0; i < (tableNo); i++)
{
table[i] = new Ta

In Mr. Selman's book, there is a section that mentions a way to index your
