What you want to do is to reduce the argument to [-pi, pi (or -pi, pi] if you want, it doesn't matter which side is inclusive), so you can represent the entire unit circle. In particular, you want pi+a (where a is a small positive number) to be reduced to (-pi)+a; your version reduces it to a. The issue gets meddled a bit by the fact that fmod(x, y) reduces x to be in the range -y, y (not [0, y as one might expect), in a perhaps not entirely intuitive way (in general, fmod(-x, y) = -fmod(x, y) for positive x and y). So what you want is something more along the lines of angle = fmod(angle, 2.0*M_PI); // [0, 2pi or -2pi, 0], depending on // sign of ANGLE if (angle 0.0) angle += 2.0*M_PI; // [0, 2pi if (angle = M_PI) angle -= 2.0*M_PI; // [-pi, pi Untested, though, and you might want to change the 0.0 to -M_PI to avoid stuff like -pi/2 to be moved up to the positive side and then back again. /* Steinar */ -- Homepage: http://www.sesse.net/ -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

This would reduce the severity of this bug significantly. I'm not sure I agree that this should be considered to reduce the severity; in the case where the value of angle is wrong by 306 orders of magnitude, there's insufficient precision to get a meaningful result with fmod or otherwise, so in practice this still may make the game unusable.

I have looked deeper into this issue, and (of course, still a problem
just in front of me - the lack of coding in the last year starts to show
its hideous face). I have seen this from the start, but I have payed too
much attention.
The issue is that angle and norme are declared locally instead of the
class. The physics engine is quite ok from the GNU POV.
I will be experimenting with some asserts in the code before providing a
final patch.

Bug#392774: wormux: blocks the whole X session when GNU touches the first object
Hi Eddy, Can you still reproduce this bug now that Xorg 7.1 has reached testing? FWIW, there is no bug in the assembly that you've cited. The problem is with the initial value of 'angle': $5 = 3.1826378988422823e+306 This number is so large that subtracting pi from it as a floating point number gives you the same number -- there's not enough precision to record a difference of 3.14 between two numbers on the order of 10^306! (And even if it could, it would take a horribly long time to reach the desired value!) So the question is, how is angle being set to a value so high? If that's expected behavior, then this code needs to get the value down into the desired range using something better than subtraction/addition. -- Steve Langasek Give me a lever long enough and a Free OS Debian Developer to set it on, and I can move the world.

I am not that skilled with assembler, but I think either the generated code is wrong or the FPU has some issues. The problem occurs at weapon/gnu.cpp:84. 82 83 while(angle -M_PI) angle += M_PI; 84 while(angle M_PI) angle -= M_PI; 85 86 angle *= 180.0 / M_PI; The code enters in an endless loop at that line but there seems to be no apparent reason for that. I have observed that the endless loop occurs if the gnu hits a wall which is inclined at such an angle that the gnu hits it with the head on the rising side of a jump. I will try to explain with some aiding ASCII drawing. \ \ \ Assume is the gnu which goes in the direction indicated by the sign.

The commands are the listed ones by DDD in its console. The first interrupt was done to define the regs macro which prints the values of the relevant registers and of the angle variable. The second interrupt was done after I managed to block the gnu. Note: Although I have assembler background experience, I don't have such experience with PowerPC assembler. I think a better skilled person at PowerPC assembler than myself should analyze the code and say if this is a GCC bug or a platform bug (at least that's what I think this problems seems to be). - --8 (gdb) run Starting program: /home/eddy/tmp/_eraseme/wormux/wormux-0.7.4/src/wormux [Thread debugging using libthread_db enabled] [New Thread 805451968 (LWP 5200)] === Versiunea Wormux 0.7.4 === Autori: Anthony CARRE, Jean-Christophe DUBERGA, Laurent DEFERT SIMONNEAU, Lawrence AZZOUG, Matthieu FERTRE, Olivier Boyer, Renaud LOTTIAUX, Victor STINNER === Situl web: http://www.wormux.org Wormux version 0.7.4, Copyright (C) 2001-2006 Wormux team Wormux comes with ABSOLUTELY NO WARRANTY.
