Re: [pygame] Adding Wii Remote support to pygame
It's not being handled as a new input-device: the 'drivers' re-mapp its functionality onto default keyboard/mouse keypresses/motions/etc. Basically it's emulating existing input devices. That's what the existing driver for Linux does as well (at least at the user-visible level). I'm hacking it so that it works with Pygame as a completely new kind of input device. So I don't think this will be a problem for porting to Windows... On top of that, it doesn't work with the microsoft Bluetooth stack, so people have to install BlueSoleil bluetooth stacks to use it. (I'm referring to GlovePIE, if there is a better windows driver available, let me know!) However, this could most definitely be a problem. I don't really know how to work around this, because I've not been paying attention to the Windows side of things. My guess is that most of the people interested in hacking the Wiimote are Linux folks, so maybe it's just not been looked at enough in Windows yet, and if we wait another month or so there will be better drivers. Or maybe there is a fundamental problem with the Microsoft Bluetooth stack? I'm no Bluetooth expert (in fact the Wiimote is the first Bluetooth device I've owned), so I'm afraid I don't have any useful advice. In the absolute worst case, I guess we have to tell people to install third-party bluetooth drivers if they want to use Wiimotes in Pygame... Perhaps I'll try to write a C-module that can do this and wrap it in Python? I'm not really sure where to go from here. That sounds promising, though possibly time-consuming. robomancer

Re: [pygame] ARGB vs. RGBA
Hello, You can use my SDL_Surface.py hack to get a ctypes pointer to the pixel data. http://www.thousandparsec.net/repos/libmng-py/mng/pygame/ I needed this to make libmng-py as fast as possible.

The code which creates the bitmasks required by the SDL conversion routine does some really strange things. For RGBA it takes the notation as a literal byte order in memory, low address first and simply swaps the 4 bytes on BE vs. LE. I'm not sure the problem. Passing the mask arguments when creating surfaces should allow any byte orderedering. size = 100, 100 rgba_mask = 0xff00, 0xff, 0xff00, 0xff rgba_surf = pygame.Surface(size, 0, 32, rgba_masks) argb_mask = 0xff, 0xff00, 0xff, 0xff00 argb_surf = pygame.Surface(size, 0, 32, argb_masks) I was thinking about pygame.image.frombuffer which requires a string (and not an arbitrary bitmask tuple). I don't think pygame.Surface allows for creating surfaces out of arbitrary python buffers.

Using such a thing would be a way to implement this. I'm really confused by this, but I've sort of got the impression that Bluetooth and USB behaved the same as far as HID drivers went... I.E. the OS hides the fact that it's Bluetooth, and the same driver would work for either a Bluetooth or a USB version of the same input device. However, I'm not sure if this is true. Anyway, I don't know if you can use HID drivers to talk to the Wii remote, I don't think you can extract all the info that way, I think you have to use L2CAP in order to get the info. The PyBluez module implements rfcomm in Windows, but it doesn't have support for the L2CAP mode that the Wii remote needs. It seems to me like they're trying to support everything on Windows that they've supported on Linux, but I'm not sure. I did manage to communicate with the Wii remote using pyBluez, and got a list of services and everything. Just can't actually get the data from it after that. I'll look for a library for communicating with arbitrary Bluetooth devices on Windows. Bluetooth support seems to be an area where Windows is severely inferior to Linux. At least as far as people implementing support for custom devices is concerned.
[pygame] Font.render barfs on spaces

[pygame] Wii Remote on Windows
I just read this article on Microsoft.com and laughed out loud. http://msdn2.microsoft.com/en-us/library/aa938557.aspx Oh, great. I can't even develop Profile Drivers on my Windows XP system FOR Windows XP. I have to install Vista, write the drivers, and run them on XP. That makes a lot of sense. Luckily, I have a copy of Vista sitting around here somewhere (Hopefully I brought it home, or I'm in for a long night of downloading). I wonder, if I use a 64-bit copy of Vista, can I develop 32-bit drivers for XP? The answer is probably obviously NO, but I thought I'd ask anyway. Since I have a 64-bit processor, I'd like to use 64-bit Vista, but I guess I'll just use 32-bit to be safe. I'll keep you all updated on my progress in this regard, and I'll let you know if I give up :) Thanks for your attention, -Luke

Re: [pygame] Tile Size
Inside... Am 17.12.2006 um 01:32 schrieb Kris Schnee: I think that a 2D, flat scrolling tile system in Pygame would be a decent compromise between graphical quality and ease of programming, for my project. I can live with the game's islands being a constant height, for simplicity. One question I could use input on is about tile size. = What blocks you to put higher tiles on the existing tiles? Right now the game world has 100x100 zones representing chunks of terrain I imagine as 1 Km^2, ie. each data point represents a 10m^2 area. I'd like to show human-sized figures, meaning you can see maybe ten times the player's width at a time -- maybe 10 meters across. For an 800x600 screen, that would mean tiles maybe 80 pixels wide for each data point. Pre-drawing a whole zone then would mean blitting from a picture 8000x8000 pixels in size! Is that impractical? = 8k x 8k is probably not that big but why creating the whole area as image? Why not adding tiles when the player is moving to a certain direction. Lets say the player is moving left, so you should add tiles on the right side while removing tiles on the left side. This would allow you to create big worlds and not limited on huge images. I'd like to use square tiles of some reasonable size, erring on the side of using a few big tiles. Maybe I should treat a zone as being just 100x100m? The level of detail on the terrain itself doesn't need to be high, because objects like trees can be added separately at any exact coordinates. (That is, I could describe an island's shape with a small number of data points saying water here, sand here, grass here and then a list of exact positions for objects.) = Same way you could add areas at higher positiones. They are rectange oriented you can check that the player cant pass them (maybe way up to them?) Since the game has an island theme I would also like to draw water translucently, which would mean blitting a water texture (or at least translucent blue/cyan) over parts of the terrain, rather than just using blue tiles as I once did ( = Sure would like nice! Instead of this you could use animated water/ land combo areas http://kschnee.xepher.net/pics/niss-05.jpg ). That also means having some way to draw water in front of or behind sprites or even some of both depending on their vertical position, right? Even if the landscape is a constant height for drawing purposes, I'd still like to have a character able to go underwater, being drawn behind the water, but also able to be above it or at the surface. = How about you can add the type of water like: 1 = low, 2 = deep low: cut a part of the charaker off (would also work for monsters following the characters or any NPC standing in the water) deep: The character is painted in deep blue or anim turns into swimming animation. Drawing water could be done on the fly each frame, or given its own drawing plane -- doubling the RAM needed for the pre-drawing -- or even given a much smaller drawing plane and then somehow scaled up each frame. What method makes sense? = Huh? Doubling RAM? I, personally, recommend you completly try to build the visual world in the tile size you planned. Many things to mention about this but all over: easier to program than handling different tyle size types and mechnisms. Just my 2 cents Farai Kris
[pygame] GLSL in Pygame on a Mac
Hello, I recently came across the GLSL example at: http://www.pygame.org/ wiki/GLSLExample This would appear to meet my needs for using GLSL from within pygame, but I cannot seem to get it working. First, as I am not really familiar with the Python wrapper of OpenGL, is that example Mac friendly? If so, is there a reason why it would fail on my machine when I have OpenGL installed? My exception (which just shows that neither loading method is working): OSError: dlopen(libGL.so, 6): image not found at file root in shader_test.py at line 14 function LoadLibrary in __init__.py at line 395 function __init__ in __init__.py at line 312 I am not really certain where to go with this, so thanks for any assistance!

Re: [pygame] map format

I think that unless you're going to be opening/reading map files all

is likely to be negligible. Get it working, then get it fast.
If loading maps does turn out to be slow, perhaps you can cache them

images as .png with information like colorkey in a seperate file.
Since I'm caching images anyhow, performance doesn't suffer much.

How do all of you implement maps? Do you use regular expressions or
simple search a string ?
I typically try to write my maps as pure Python that call game
engine functions. For instance, I've been toying with something like this:
setMap('''

1
0''')
setTerrain(0, passable=True, tile=grass)
setTerrain(1, passable=False, tile=forest)

Re: [pygame] map format
I just use .tga files -- and surface.get_at() and surface.set_at().
You get limited to 256 tiles and 4 layers, but I've yet to have that be a
problem. Quite adequate for any small game -- and it's simple. If you need
to upgrade later, you can always change to a text based format that supports
more stuff.
