What are you working on? v19

[northshore]

I'm working on Python :downs:

I bet all you Programming Kings are like "Wow, he's doing that wrong." :v:

Also, can someone explain to me what everything from done=False down means?
I'm just following the examples from a beginning Python/Pygame programming book and I have no idea what it does, just that it has to be there.

Well I suggest that you read PEP 8, your coding style now is really inconsistent and if you stick to PEP 8 then everything will be swell for you and other python programmers.

Your using arrays to pass co-ords etc. to pygame. I'm pretty sure that even though that works you should be passing tuples. I can't think of the reason know right now, but that's how I learnt and everyone does as well. If anything do it because it looks nicer.

Tuples conceptually make more sense because here any wonk can add items to a coordinate triple. In a statically typed language you'd actually encode the tuple size in the type.

Does anyone know a good resource on how to do proper networking for a small game (4 players max with almost no other objects that need to be networked)

[Dr Magnusson]

Wrote a small program to convert Wavefront .obj files into a binary format that I could load straight into a mesh.

The binary output file is bigger than the plaintext input file.

This is unbelievably pedantic.
Also, newbies shouldn't have to worry about style issues except where it poses a very real problem (i.e. having a function with eight levels of indentation).

This. wat.

Also, if you're looking for a simple binary model format (and don't necessarily require Wavefront), try [url=http://lee.fov120.com/iqm/]IQM[/url].
It's simple and logical while still having modern features like skeletal animation and even adjacency data (for geometry shaders). If it doesn't have what you need it's also pretty extensible. The reference implementation is public-domain, although you might not want to use any of it as-is (some of it is a little gnarly). It has compilers for common formats like MD5 and SMD and is one of a minority of formats to have export scripts for Blender 2.5 (Blender threw out their entire API and started over, breaking compatibility with their massive library of older scripts).

[Dr Magnusson]

It's because it's just a simple cube, and the .obj format uses the faces to reference vertices/texture coordinates/normals/whatever, so while the object file stores each point only once, I have to put it in there once for every time it's used, and since I'm using triangles, each corner is used 8 times.

Anything more complicated than a cube would make the binary output smaller.

That's stupid. Just use references the same way - by specifying a index into the vertex list (4 bytes max, you could probably get away with 2 or 3) instead of a whole new vertex (12 bytes).

I'll optimize later, right now I just want to get stuff working first.

I Googled PEP 8, so I'm reading that right now.

Can you explain "tuples"? Didn't read that anywhere in the book so far.

Note that for the specific case of a textured cube you run into the same problem either way because you have to duplicate verts along the model's seams to have different texture coordinates. In most models seams compose only a tiny fraction of the model's edges.

It's the immutable (cannot be changed after initialization) version of a list. A tuple is denoted with regular parenthesis instead of rectangular brackets.

Unless you use texels and tfaces (or just have an index into the texel list in your face list). You should really separate texture coordinates from 3d space coordinates, otherwise yes, you do get a lot of redundant vertices.

This sounds like it would require more processing in your loader/renderer. At least with OpenGL, generally the same index is used for all vertex attributes. I don't think you can have (in the core profile, at least) texture coordinates separate from other vertex attributes without incurring some sort of massive performance hit.

Well, it's also easier to load a TGA/BMP than a PNG or JPEG, yet people write loaders for other image formats, right?
You just need to process it while loading, as you would have to convert it to something usable by your renderer. I'd rather lose 20ms while loading than have a bigger file format.

You could also probably hack around it by converting the texel list into a 2D texture usable from your vertex shader, but that's just evil :v:.

A while ago I wrote a similar program, but it still followed the referencing of the .obj format and even expanded a bit on it. For instance, I made floating point numbers references as well. You can take a look at it if you want.

I'm fairly sure the point was to create a format that could be loaded straight in, otherwise you could just keep using something like .obj

EC2 may be expensive for the super-high power/ram instances, but when you need a really cheap server that doesn't need to be that powerful, and you need it now then its very useful.
By cheap I mean free for 750 hrs. Renting a vps that has about the same specs (a little better) is much more expensive (I think). It probably isn't the best choice for bigger websites though.

As for what I'm working on, its a program to answer a question of mine. When downloading something through tor, I want to know if me getting terrible speeds is because of my connection, or because of tor.
I want to see if I can get better speeds if I am using something with a line 1000x as powerful as mine. (I download at 250kb/s, it downloads at 25mb/s). My question is, why the fuck is this timing out?

[csharp]
Console.WriteLine("STARTED");
HttpWebRequest request = HttpWebRequest.Create(uri) as HttpWebRequest;
MemoryStream temp = new MemoryStream();
byte[] buffer = new byte[8196];
int pos = 1;
int numread = 0;
using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
{
using (Stream sr = response.GetResponseStream())
{
while(numread!=0)
{
numread = sr.Read(buffer,0,buffer.Length);
if(numread!=0)
{
temp.Write(buffer,pos-1,numread);
pos+=numread;
}
}
}
}
[/csharp]

uri is just a new Uri("http://www.google.com");

I know it's an old joke. Just wanted to point out that it does look like Lisp. Even if it uses the reverse notation.
