Sorry. Here is my problem: I installed a variety of software on my machine. It's a simulator we are trying to write that simulates robots in the RoboCup Junior competition. The simulator (called arena) uses bullet physics, irrlicht and blender. It works perfectly well on four systems at the moment. But it doesn't run under mine. Well, it does - in a way.
It compiles perfectly and everything but when I start the simulator I get the field and shortly after the robot is initilzed. The program positions the robot above the field and it falls down a bit. Now here things start to differ on different machines:
Normally, the robot drops down to the field and stays there. It works like a charm and one can for example start the program that runs on the robot. So the robot moves forward, sideways, everything...
On my machine the robot falls down but when it reaches almost the field it disappears (to be more precise: the coordinates become NaN).
The lead programmer in our team (which is not me) doesn't know any solution either.
However, we did some further analysis:
The coordinates turn NaN when the robot are close to the field. It doesn't matter if the field ist positioned at a global height of 0 or of -1 (meter).
Code: Select all
X = 0.000000, Y = 1.752025, Z = 0.250000
X = 0.000000, Y = 1.752025, Z = 0.250000
X = 0.000000, Y = 1.752025, Z = 0.250000
X = 0.000000, Y = 1.752025, Z = 0.250000
X = 0.000000, Y = 1.752025, Z = 0.250000
X = 0.000000, Y = 1.713875, Z = 0.250000
X = 0.000000, Y = 1.713875, Z = 0.250000
X = 0.000000, Y = 1.713875, Z = 0.250000
X = 0.000000, Y = 1.713875, Z = 0.250000

X = 0.000000, Y = -0.945725, Z = 0.250000
X = 0.000000, Y = -0.945725, Z = 0.250000
X = 0.000000, Y = -0.945725, Z = 0.250000
X = 0.000000, Y = -0.945725, Z = 0.250000
X = nan, Y = nan, Z = nan
X = nan, Y = nan, Z = nan
X = nan, Y = nan, Z = nan
Differences/Setup on the machines are as follows:
Working machines:
Running Linux, Kubuntu 8.10, 32bit with KDE4 (4.1 and 4.2) (on three different computers)
also Ubuntu on a MacBook with wmii, also 32bit.
Not working machine (mine):
Kubuntu 8.04, 64bit
We are all using the same bullet version (the newest one).
Could anyone help resolve this?
Cheers,
Chris
