Re: [pygame] Sound not playing at startup

Thanks much, Arthur I am just taking a wild guess here, but I suspect that ALSA will not yet have finished initting when rc.local is run. When I did an embedded project, I started my program using rungetty from /etc/inittab instead of using rc.local Install rungetty, and then edit your /etc/inittab so that rungetty will log in a user automatically on one of the virtual consoles, for example, log the embedded user in to tty2: 2:2345:respawn:/sbin/rungetty --autologin embedded tty2 Then you can edit /home/embedded/.profile to run your program. --- James Paige

Re: [pygame] playing sound on Windows
I don't know why this problem is happening, but I can reproduce it.
I tested your script (with my own 0.wav file) and it worked fine on
Linux, but on Windows 7 (64 bit) with both python 2.6 + pygame 1.9.1 and
python 2.7 and pygame 1.9.2 there is no sound.
Although this does not solve your problem, I think you should remove the
pygame.mixer.pre_init() because inside the class but not inside a
function is definitely the wrong place for it, and even if you move it,
all it does is change the defaults for pygame.mixer.init() to the same
values those defaults have already.
You can also add
print pygame.mixer.get_init()
and it will display the settings with which the mixer was initialized,
or if mixer init failed entirely it will return None.
When I tested, .get_init() returned (22050, -16, 2) indicating that the
init succeeded with the default settings.
Before I tested your script on my windows box, I tested my 0.wav file in
audacity and it sounded fine.
After I tested your script, and the sound failed to play, I tried it
again in audacity, and then it would not play.
Even though I could not get the .wav file to play anymore either in
python or in audacity, the windows volume mixer test sound still worked
find.
Very strange.

Re: [pygame] Using Pygame to capture key presses for CLI prgram?
A couple years ago I was trying to do something very similar. It wasn't a raspbery pi, but it was a very small fanless linux box running debian. In production, it had no monitor and never ran X. All the output was to a serial LCD and all the input was from a barcode scanner that sent keypresses as a keyboard. I tried to use pygame for reading the input, but I finally gave up. Without a window, pygame is just the wrong tool for the job. I finally ended up using python's termios module. Here is a small wrapper that I used http://pastebin.com/q9xMVUSb I also found the timeout module handy in combination with reading raw stdin, but whether or not it will be useful for your program I don't know. --- James Paige On Wed, May 29, 2013 at 05:05:59PM -0700, winkleink wrote: Hi, I'm running pygame in a raspberry pi.

Re: [pygame] Ongoing Development
This answer is a matter of opinion, and I am sure other people can offer different viewpoints, but for myself, I would suggest focusing on pygame1 for any projects you are starting *today* It has a long history of being stable, people have made tons of games with it, and by the time pygame2 is finished, it is very likely to have a backcompat interface so pygame2 will be able to run pygame1 games with a minimum of modification. Maybe later, when pygame2 is a little more mature, it will make sense to start with it, but your experience with pygame1 will certainly not be wasted when that time comes. Other opinions welcome :) --- James Paige On Tue, Apr 16, 2013 at 08:56:32AM +0100, Andrew Barlow wrote: Yeah, it'd be great to know the differences between PyGame 1 and 2, advantages, disadvantages, etc. My big question (besides all the others I've posted ;-) ) is which should I be using if i'm starting a project, right now?

I'm not sure to understand the difference between the 2 solutions you suggest but it seems reasonnable to assume that the horizontal and vertical ratios are the same (a square image of say 256x256 pixels will be displayed as a square). I will try to code a simple application in order to test. Mathieu Unfortunately, no you cannot assume a square aspect ratio.

Yes, that is absolutely correct. You can have multiple different versions of python installed, and pygame must be installed separately for each of them. pygame must be compiled to match the version of python you are using, and if the version does not match, then python will not be able to import pygame.

If you are running on windows, it is highly recommended you use this form of installing. The installers come with with nearly everything you need, and have an easy point and click installers. The first thing you will need is an installation of Python. Python binary installers make it easy to get this done. Pygame binaries usually come for the latest 2 releases of Python, so you'll want to be fairly up to date. Once that is in place, you want to download the appropriate windows binary. From the pygame downloads page you can find the .EXE file you need. This will automatically install all of pygame and all the SDL dependencies. The windows binaries have filenames like this; http://www3.telus.net/len_l/pygame-1.8.0release.win32-py2.5.msi;. This would be the installer for pygame version 1.8.0, for Python version 2.5. You shouldn't have trouble finding the correct binary from the Windows section of the download page. http://www.pygame.org/download.shtml. You will also probably want to install the windows documentation and installation package. This will add easy links to the different documentation and games that come with pygame. The installer for this is found next to the other windows binary downloads. The filename looks like this; pygame-docs-1.8.0.exe. And this would install the documentation and examples for pygame-1.8.0 One other thing the windows binaries are missing is the Numeric or numpy Python packages. You can easily install this separately and it will allow you to use the pygame surfarray module. This module is optional, so there is no need to do this. There are binary installers from the Numeric download page. http://sourceforge.net/project/showfiles.php?group_id=1369. A Numeric for Windows python 2.5 can be found on the download page: http://www.pygame.org/download.shtml.

Re: [pygame] trajectory
In most (but maybe not all) tower defense games I have ever played, bullets *can* change direction in flight, and do behave like homing missles. This isn't obvious visually if the bullets are fast, but it is pretty common in tower defense games that if a target is in range when the bullet is launched that it will always hit the target no matter how it moves. That being said, I don't have any idea if Nathan Biagini wants to make his own tower defense game work that way or not :) --- James Paige On Fri, Jul 22, 2011 at 08:24:51AM -0700, Lee Buckingham wrote: Unless the bullet can change direction in flight, it will have to choose one, and only one spot to aim for, and therefore, one vector to guide it. Homing missiles are a lot different to code for, since they have to adjust course, and potentially deal with a synthesized form of inertia. A bifurcating tree of solutions seems to suggest looking at all possible 'likely' positions for the target in the future. That's not so much vector math as it is statistics and player-psychology. You also probably don't want to deal with linear solutions to this problem, unless you really really need pinpoint accuracy on each shot (again, assuming NOTHING changes direction or speed after a shot is fired, which makes all that accuracy useless anyway). Breaking it up into steps that are a little smaller than the clipping rectangles involved will probably get you more than close enough. Furthermore, there will be a different solution to the linear form of the problem for every firing angle (wide angles intercept later, etc...) It would get pretty ugly. It might suit better to 'fudge' in a calculation. Make an estimated change (just add a constant or something) to the current position of the target, based on it's speed and direction, and fire at that position. Divide the x and y distance to the target each by the speed of your bullet (you don't even NEED to do the trigonometry for speed calculations, the player wouldn't notice much anyway) and make the bullet move that much in the x and y directions each tick. Try it out... are your shots firing too far ahead? Too far behind?? Change the estimation constant a little bit and try again. If the target is in close, you might have to reduce the estimate a bit, etc... You can probably tweak this one enough to have a very satisfying firing computer without having to go through the hassle of reading the physics chapter on ballistics.

Re: [pygame] Making UPS smart with Pygame and Joystick input socket
I was assuming that you were talking about a USB joystick or gamepad. Are you talking about the old midi-port style joysticks? the ones where the port is usually on the sound card? I have no idea if pygame supports those at all... I am not sure if they even show up as joystick devices in the linux /dev tree. I suspect that they probably do not (not unless you are using a really ancient kernel) The reason I assumed that you were going to disasemble a joystick is because I was thinking of a USB joystick. You need the joystick to identify itself as a joystick on the USB bus. You could probably still connect your UPS to the joystick as you planned, although now I am thinking you might have an easier time connecting to one of the analog inputs instead of the buttons.

All the files of my project can be found in this download: http://www.mediafire.com/?pbr8kubwu9q7vg0 The slowdown I'm experiencing (under Fedora 14/GNOME, at least) is a ridiculous level.

A fair amount of stuff happens, and even some pixel work with surfarray happens, but I would not expect any less than maybe 10 FPS, and that's really stretching it. Most of the slowdown seems to occur in the PlayerSprite.update and PlayerView.update methods. Looking at the system monitor, it seems that the program is eating up clock cycles like a starving lion. My question is: can anyone see a good reason why these methods would cause as much slowdown as they do? If so, any recommendations for optimizing it better? Thanks! :)

If you said, On a KEYDOWN event, set speed to N and set direction to whatever; and on a KEYUP event, stop, then the result should be that the character keeps moving until you let go of the key. If you said, On a KEYDOWN event, move, then you should get one frame of movement each time you press (not hold) the key. My advice is to figure out what the player's trying to do first, like move right, and then actually execute the movement in a separate bit of code (if moving right...). That's useful for things like replacing what keys do what, or having some non-interactive event steer the character. Could I use keys_down = pygame.key.get_pressed then if keys_down[K_RIGHT] ## move right, in this way: class character(): def update(self, d, sp): if d == 6: self.x += sp elif d == 4: self.x -= sp elif d == 8: self.y -= sp elif d == 2: self.y += sp Why use this odd numeric-keypad code for the direction? Other than the variable names and that code, this looks usable. But think about what'd happen if I pressed RIGHT and UP at the same time: the code would see the RIGHT, set the direction to right, then probably see the UP (depending on which was mentioned last in the code) and change the direction to up. A different way to handle the movement would be something like: player.coords = [42,100] ## some starting value ## In a loop: movement = [0,0] if keys_down[K_RIGHT]: movement[0] = speed ... if keys_down[K_UP]: movement[1] = speed ... player.move(movement) def Move(movement): self.coords[0] += movement[0] self.coords[1] += movement[1] You'd then get diagonal movement, and not have to specify the direction, and could apply

But you might want to look at where in your program's main loop you're playing the sound. For instance, is the sound getting called only after some complex processing of other game events? That would delay the sound. It is also a good idea to open up your sound files in audacity and check to see if they have any silence at the beginning of the file.

Since it tries to prevent flooding of the event queue. Well it does for mouse events anyway. I can't remember if they fixed/changed stuff for the recent 1.2.14 release... but it's worth trying out if you haven't already. Interesting. My main Linux testing box has SDL 1.2.13. I'll give it a shot. Also, maybe try out the 'xev' command - which prints x events. Then you can see if it is printing out all the events at the X level. man xev I just tried that, and no X events are being lost. Oh, also, I figured out why I was getting almost universal failure in my test app but only the first scan was failing in my production app. In the production app I was only testing with barcodes, and only the first scan would lose repeitious events. In my simplified test app, I was actually switching between the barcode scanner and my regular keyboard. I would scan 222333 and then I would type z to have a visual delimiter between that and the next scan. When I did that, almost every single scan would lose events. So it seems that SDL actually only loses events from the first scan after the main keyboard has been used. I tested this further, by launching my test.py script, testing it, then closing it only using the mouse, then running it again only using the mouse. Then the first scan did NOT lose events. This is very encouraging to me, since it means that solving this problem or working around it is no longer a critical issue for me, since this barcode application is going to be running on an embedded computer with no main keyboard anyway.. But I do still want to solve this mystery from a mystery-solving perspective. I just no longer need to solve it from a getting-my-work-done perspective :) --- James

In my stripped-down mimimal test app, the events are lost almost 100% of the time. In my actual full aplication, the events are only ever lost on the first scan. Weird. I'm sure you've already thought of this, but you could always just open /dev/keyboard or whatever and manually post keyboard events yourself, or just use the keyboard data directly... I have no idea where to look for the usb keyboard device associated with the barcode scanner... and even if I could find it, I am fairly certain that my app would have to be running as root if I wanted to read directly fom it, so that would be unacceptable :( And you could even roll this in to a module so other people could use it too. Might be hard to make it cross-platform though and it sucks to have to completely throw out SDL's keyboard event handling. Also I don't know how you'd keep SDL from posting repeated events, I guess you'd just create your custom events under a different event ID and just watch for that ID instead. Re-implementing my application in pygtk or wxpython sounds like a hell of a lot less work :) 4) I also discovered, while searching for a workaround, an SDL mailing list post from Sam Lantinga last January mentioning a simple callback mechanism for SDL events that bypasses the event queue. Does anybody know if there is a pygame way to make event callbacks? I don't know, but I'd guess it would be possible with Pygame-Ctypes.

Checking distances for every tower and every unit could become a bottle neck but would work. If you have performance problems you could also incorporate a grid. When every unit moves it can do a check to see in what section of the map it is found in (ie, grid could have 10x10 tiles in each square) and you would only check the distance of creeps in the grids that are in range of the tower. One thing to keep in mind would be that in some cases you may be able to stop the iteration as soon as you find someone who is attackable (if the tower attacks random creeps) otherwise you just compare the distances of the creeps and sort.

(btw, this is why contrast ratio doesn't matter so much for home or movie theatres with paltry contrast ratios of 1:500 but the environment is blacked out - our vision readjusts very well to just using the range provided) The big thing about all this new monitor stuff is the new high-contrast displays, as Pierre said new TV with retro light using LEDs has higher contrast (up to 200:1 wich is about 126 DB dynamic range). People who have seen those new monitors have told me the pictures looked like real life, that it was like looking out a window, not at a monitor. With those new high contrasts though, if you aren't using the full contrast range for a particular scene, RGB888 can be way too small. So more range is needed if you wanna do something like go from a cave to the out of doors - if the cave is half as bright with RGB888, you dropped half your range, to RGB777, and your eyes can start seeing bands and such better. So the big difference, if I inderstand you correctly, is: RGB888 is over 16 million colors MAX, but the average human eye, being dynamic, distinguishes somewhere around 7 to 10 million colors AT A TIME. RGB is designed to be close to our rods and cones, which for most people see an R with very good color range, a G with good color range, and a B with mostly OK color range (relatively speaking). That's why many restricted bit color schemes with uneven bit allocation put the extra bits in the R or G but never the B. But there are actually some people (I've heard they are mostly if not all women) with an extra cone (I think) that is pretty close to the B, and those people have amazing color perception much much better than RGB888, and usually work in color and print related fields cause they can do things like match paint samples and colors at a level beyond what us normal people can. I have heard of that! Tetrachromatism! Apparently the most common forms of red-colorblindness and green-colorblindness are not that the red or green cones are missing, but that they are present but picking up the wrong wavelengths. So if you are Red-blind that means your cones are GgB Green, Different Green, and Blue. And if you are green-blind then your cones are Red, Different Red, and Blue. RrB Both mutations are carried on the X chromozome, and both are recessive traits. Since women have two copies of the X chromosome, they rarely have any colorblindness, because they almost always have a good copy of the Red or Green gene on the other X, but men having just one X are far more likely to have colorblindness. Tetrachromatism (If I recall correctly) happens when a woman gets one different kind of colorblindness on each X. Somehow, sometimes this results in the Other Red and Other Green cones combining to behave like a population of Orange cones, so her vision is effectively Red-Orange-Green-Blue and she can see orange as if it was a primary color, instead of as a secondary color like most of the rest of us do. --- James Paige

If these auxillary adapters are anything like the USB video adapters I have used myself, they just flat out don't support 3D acceleration of any kind. SDL 1.3 and DirectX will not help.

Re: [pygame] Pygame Installation problems (Python 2.6.2)
Ah, that is cool. I had a feeling it would be easy on Linux ;)
My comment about manually building the dependencies was actually
directed to the 64-bit Windows side of things.
For 64-bit Linux all that needs to be done is verification that 64-bit
works (as you have done)
For 64-bit Windows, I think it might be good to actually post a prebuild
installer alongside the 32-bit one on pygame.org

Re: [pygame] Re: Implementing save feature
Unfortunately, no, I don't have any good examples for you, because most of my xml experience has not been python based. You might want to look at the xml modules available in the python standard library documentation. You can choose from expat, minidom, pulldom, sax, elementtree, or maybe some I am forgetting. Maybe somebody else on the list can suggest which is the best match for pygame. In general though, you will probably end up with a file that has a node for general data, with some named data elements inside it, and a node for inventory with a list of item elements inside it, and a node for flags with a list of flag elements inside it. --- James On Fri, May 22, 2009 at 03:09:59PM -0700, Nevon wrote: No, it's not super important.
