I've yet to try this in any way, shape, or form, but I
thought I'd see what
everyone thinks first.
I have a waterfall
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?

Typo ? Did you mean i tableNo ?

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.

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.

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 !

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
