Re: [pygame] Problems with py2exe and Pygame
Hi,
you can use the datafiles option in your setup.py to copy the font.
Maybe take a look at my setup.py script:
http://schoolsplay.svn.sourceforge.net/viewvc/schoolsplay/branches/childsplay_sp/windows/setup.py?view=markup
It's fairly straight forward.

Yes my setup script uses py2exe on windows and cx_freeze on linux,
while keeping the data movement code generally shared for either

really am a loser. Instead of using shutil, I wrote all of my own
shell functions :)
To answer the actual question...
We really need to see what code is breaking to know what is wrong
here. I think you may need to specify an actual named font rather
than relying on the default one, in order to pick up the ttf in the
exe directory. Uh, one more thing. Try manually putting the font
into library.zip.
You'll be safest to manually load the font yourself though, with the
pygame.Font function.

Maybe I'm a loser, but I generally keep the setup.py script short.
If I've got to move files, I do that from a bat script which can
call my Windows installer compiler too (inno, my case).
A good reason to keep this stuff in python (regardless of whether it
is in setup.py or not) is portability. bat files only work on
Windows. But then again, absolute paths (especially ones that use
drive letters) are highly non-portable anyhow no matter what language
they're in (even on different machines that are running Windows).

(I saw some posts about that problem) But the error log when I try to run it says this: Traceback (most recent call last): File lunarlander.py, line 111, in module File lunarlander.py, line 49, in display_stats RuntimeError: default font not found I'm running python 2.5.1, Pygame 1.7.1 and a recent version of py2exe (I don't know how to find the version number, but the modified date on the build_exe.py file is October 3, 2007). One way to avoid this problem is to use a font explictly, instead of using the default. With the font in the dist directory it won't get loaded as the default, but you ought to be able to load it by name.
Re: Fwd: [pygame] Problems with py2exe and Pygame
I did also manually put the font into library.zip. Still had the same problem.
Then I took the suggestion from another post and explicitly loaded the
freasnsbold.ttf font, instead of using None (and getting the default.)
That worked, but all my fonts rendered about 50% bigger than before. Strange.
But at least now I can distribute it.

(ping pong) As for bouncing indefinitely, pong takes place in a magical universe where no energy is ever lost :) It's funny how you don't ever have to worry about going over the net. Why they didn't just name it hock (air hockey) we'll never know.

(ping pong) So it would be a case where the bounce is sideways, like hockey or soccer. As for bouncing indefinitely, pong takes place in a magical universe where no energy is ever lost :) And now, for your random amusement: Well, some energy must be lost from the ball, and transferred into the wall, (so the walls should move as well as the ball). That way, the energy would be temporarily lost to the ball, but then given back to it when it hits the other wall, which is moving towards it. Actually, that's sort of what happens. The energy of the ball goes into the Earth, accelerating it VERY slightly. If collisions were totally elastic, and friction was zero, the ball would bounce forever. Either that or the ball must be infinitely light, in which case, it would be accelerated to the speed of light by a touch. However, as long as the object it comes into contact with remains motionless, the bounce will just be a bounce, and not a speed change. (Velocity changes because the direction does). On the other hand, since the ball is massless, the ball's velocity can be changed instantaneously. Because the contact time is nonexistent, the speed of the paddle per unit of time is irrelevant, so it would always bounce and never accelerate. Even friction would have no effect. (Air friction, caused by air molecules, for example, would cause the ball to bounce rapidly between the atoms- no energy would even be lost as heat, or would it?). Note that these two cases only work if the ball has a set speed to begin with. If it was at rest, a single atom of gas would accelerate it to light speed. If it was going at light speed, there is no way to stop it because it would retain the speed of any collision. If it hit another atom of gas, it could not transfer energy because it does not have any mass to carry the energy. Or would it? Physics says that the same force is required to stop a particle as took to accelerate it. So identical atoms at identical speeds could both stop and start the ball? However, Physics, as far as I know, does not say what happens with a particle of no mass. Now, according to Wikipedia, the mass of a photon is zero. Yet we know that photons carry energy (shine this: http://www.youtube.com/watch?v=vXDYCGVEMac into your face (don't)). Since energy is mass (the conversion factor is the speed of light squared), photons must have effective mass. Yet they don't! Somehow, they can obviously be created and accelerated. So, there are your magic particles, but we don't often see them going slower than the speed of light, not to mention small, so they're useless for Pong. Of course, there is a paradox in all this, that the ball can retain kinetic energy, yet have no mass. It could be viewed that, by Physics, it could not impart energy with no mass, because energy transfer is proportional to the mass and speed of an object. But photons accelerate, at least, so ??? Incidentally, ask someone what (1/infinity)*(infinity) is. I want to know. Best not to analyse it too much. :-) Ian

Some things you might be able to exploit: * Non-commuting observables - an object that you can determine two different things about, but not both at the same time. Observing one makes the other indeterminate, so by making alternating observations you can change its state. * Interference - something can happen two mutually exclusive ways, but to achieve a desired outcome it has to happen both ways at the same time. You achieve this by closing your eyes and not watching what happens. * Entanglement - two distant objects are connected in such a way that observing something about one of them has an effect on the other. -- Greg

I don't pretend to understand the implications of this discussion, but it sounds to me like, at the speed of light, frequency is analogous to mass at lower speeds?
Re: [pygame] Why does my ball vibrate?
a while ago someone said that the ball speeding up and slowing down randomly was because it was based on the time elapsed every frame and that time varies because if other tasks are being run then the cpu is executing both threads so it doesn't spend all of its time in your game. But then what workaround is there for physics simulations that are based on time?
