Learning SDL_net / network programming

high,

ive recently got the desire to learn network programming. i would like to
use SDL_net because i use the other SDL libs for the rest of the game, and i
would like to use SDL_net for the network part. SDL has been good to me =).

anyway, its sad but i cant find much info on SDL_net. anyway, heres my
question:

should i buy a book on winsock programming, learn how to do it with winsock,
then use what ive learned and teach myself SDL_net ? or, should i search
the net far and wide and teach myself net programming strait away using
SDL_net? what do you think? thanks for any help!>From: sdl-request at libsdl.org

I don’t understand completly what the granularity concept means…

/*
quote:
SDL_Delay will wait at least the specified time, but possible longer due to
OS scheduling.

Note: Count on a delay granularity of at least 10 ms. Some platforms have
shorter clock ticks but this is the most common.
*/

Does it means that if I want to wait 22ms, I need to use SDL_Delay(12) ?
(because 12+10(the granularity) =22)

I’ve started learning C++ and decided the best way to do that is to write
some
games. As such, due to my previous experience with Perl, I knew about SDL,
and
decided to use it. My problem is this site:
http://www.libsdl.org/intro/whatplatforms.html
It says there are two versions of SDL for windows, one of which is safe,
the
other isn’t. My problem is there is only one version of the dll and
development
files. Could someone please clarify what this statement means?

Thanks

Before diving into SDL on WinXP, can someone tell me, to what extent can I
control the audio card with it? I want to be sure that only my app’s audio
comes out, and none from any other apps running concurrently, for as long
as my app is running. I also want to be sure of no delays greater than 20
ms.

If not, what can anyone suggest I use to achieve these goals?

Hi,
I’ve just started playing with SDL (in preparation for a final year
project for a Computer Science BSc) and it’s great. I made a quick app of
some floating objects, using SDL_FillRect to fill the screen with a color
at
the start of each loop, then drawing the rest on top, like this:

SDL_FillRect(screen, NULL, 0xCCCCCC);

This works great in a window, but if I change the SDL_setVideoMode 

call
to make it fullscreen, it’s as if SDL_FillRect is totally ignored; the
background is black and the objects on top leave trails as the background
isn’t being rewritten. I’m using Windows XP and Visual C++ 6; I guess it
might be something to do with DirectX being used in fullscreen? Or maybe
something with the screen buffers pointing the wrong way. I don’t know
really, that’s why I’m asking :slight_smile:

Thanks

Subject: [SDL] Beginner SDL+MINGW: Where is sdl-config?
To: sdl at libsdl.org
Message-ID:
Content-Type: text/plain; charset=“us-ascii”; format=flowed

I am trying to install SDL under MinGW.
I have followed the instructions located
at the following website:

http://www.libsdl.org/extras/win32/mingw32/README.txt

Here are the six steps mentioned in the above “README.txt” file:

      Step 1. Download the msys package, version 1.0.8 or newer, and

install it.
Step 2. Download the latest stable version of the MinGW
package.
Step 3. Run the msys shell. Further instructions assume
you’re in this shell.
Step 3. Unpack the MinGW package in the /mingw directory.
Step 4. Move /mingw/bin/make.exe to
/mingw/bin/mingw32-make.exe as directed.
Step 5. Extract the SDL source into a directory and run:
./configure && make && make install
Step 6. When you’re ready to build SDL applications, copy
SDL.dll from
/usr/local/lib to whereever your SDL application
source resides.

Here is the results of my attempt
to install SDL on top of MinGW:

(Steps 1,2,3): I downloaded the following files from www.mingw.org

    MinGW-3.1.0-1.exe   -> Installed to c:/msys
    MSYS-1.0.9.exe      -> Installed to c:/mingw

(Step 4) I moved c:/mingw/bin/make.exe -> c:/mingw/bin/mingw32-make.exe

(Step 5) I downloaded SDL-devel-1.2.7-mingw32.tar and unpacked it to
d:/sdl-lib/mingw
When I tried to run ./configure there was no such file. However
there was a “configure” file in the test subdirectory so
I ran that. Here is the output of configure:

    checking build system type... i686-pc-mingw32
    checking host system type... i686-pc-mingw32

    configure: error: *** SDL version 1.2.7 not found!

Where is this file “sdl-config”? I found a file called
"i386-mingw32msvc-sdl-config" in my directory
"d:/sdl-lib/mingw/SDL-1.2.7/bin/" so I copied this file to
sdl-config in the same directory, added this directory to my
PATH variable (via the Start->Settings->Control
Panel->System->Advanced-> Environment Variables)
but when I ran configure, I got the
following error:

Message-ID: <loom.20040424T223219-389 at post.gmane.org>
Content-Type: text/plain; charset=us-ascii

I’m looking to do one of the most simple operations: blitting a 24 bit
bitmap
with the color 255,0,255 defined as the SDL_SRCCOLORKEY.

I’ve looked up examples online and I appear to be doing things the same way
as
others, except I notice people using 0,255,0 as their background color–
perhaps
there is a sort of inversing going on behind the scenes that I don’t know
about?

Anyway the code is quite simple:
SDL_SetAlpha( ball, SDL_SRCCOLORKEY, SDL_MapRGB( screen->format, 255, 0,
255 ) );
and a
SDL_BlitSurface( ball, NULL, screen, &dst );
The screen is created with
SDL_SetVideoMode(800, 600, 24, SDL_HWSURFACE|SDL_DOUBLEBUF);

I have tested two different bmps, one made in PSP and one made in MS Paint.
The
image blits but with the background color included.

Here is an example online I found which happens to match what I am trying:

I like SDL_draw and SDL_gfx but am having difficulties compiling them
both.

SDL_draw compiles with lots of errors.

I can get SDL_gfx compiled as static library (.a .lib). I don’t know how
to
use this static library with my programs. So I try to compile as dynamic
library (.dll) but I get lots of linker errors.

Please can someone see if they can compile SDL_draw and SDL_gfx under

make sure your main is defined like this:

sometimes i get that error and it’s because main is declared as returning

It sounds like you need to include <windows.h>

You don’t need to use loadlibrary to use the dll-files though. All you
need to do, is in the Project Settings/“C/C++”/“Use run-time library” to
set “Multithreaded DLL”. That, and linking to SDL.lib and SDLmain.lib
works like a charm.

The “granularity” is the resolution of the timer. If the timer
granularity is 10ms, you can wait for 10ms or for 20ms but not for 22
(it will wait for 20 or 30, depending on the implementation, I guess)

10ms granularity means that the clock is only accurate to minimum 10ms.

that means if you tell it to wait 23 ms, it’ll wait 30.

might be more to it but thats the general idea :stuck_out_tongue:

You could draw a black transparent rectangle on top of each tile to
darken it. Using different alpha values, you might achieve the desired
result.
However, that’ll be slower because alpha is expensive.

Hi,

After reading bob pendleton (bless his heart!)'s demonstrations on
SDL_Net2,
I’m curious whether it’s even worth my while to be learning how to do
SDL_net, seeing as it’s apparently not thread-safe.

Depends on what level of “thread safety” you need. If you put all
networking in a single thread, it doesn’t matter if the library is
thread-safe. SDL_Net2’s big advantage, as I understood it, is wrapping
the networking in the SDL event system.

Does anybody else have recommendations for simple game/network
programming
using using SDL, which you prefer? Even using directPlay in a windows
environment, I’d be open to alternatives.

Well, I recently extended SDLnet to non-blocking TCP (Windows and *nix
only, so far), which makes networking in a single thread rather
painless. It’s not been thoroughly tested, but if you’re interested, I
could send you the code.

On the other hand, I recently discovered the OpenTNL networking system, which seems very impressive. You may want to check it (http://www.opentnl.org). It should be scalable to small applications, and seems easy enough to work with, but the learning curve is terribly steep. I just don’t want to be programming halfway into my game and have to re-engineer using a different library because of a structure deficiency in the library. Well, you could put a generic wrapper layer around networking, and then you would only have to change the backend. Usually overkill, though :frowning: Hope this helps, Ben Message: 19 Date: Wed, 12 May 2004 20:30:18 +0200 From: Tom??

You can use one of the other backens available, for example the
framebuffer one. I don’t know if this works with uClinux, but it doesn’t
need X11.

I’m looking to do one of the most simple operations: blitting a 24 bit

I’ve looked up examples online and I appear to be doing things the same

perhaps
there is a sort of inversing going on behind the scenes that I don’t know

Anyway the code is quite simple:

255 ) );
and a

If you want to do colorkeying, you should use SDL_SetColorKey and not
SDL_SetAlpha. SDL_SetAlpha is for semi-transparent surfaces.
See the SDL_SetColorKey manpage for that.

There are. But at least they’re from last month, not last year :wink:

Hi

You could have a look at Beej’s guite to network programming. It’s very
easy to understand. With that knowledge you should have no problem with
SDL_net.

ive recently got the desire to learn network programming. i would like
to use SDL_net because i use the other SDL libs for the rest of the
game, and i would like to use SDL_net for the network part. SDL has been
good to me =).

anyway, its sad but i cant find much info on SDL_net. anyway, heres my
question:

should i buy a book on winsock programming, learn how to do it with
winsock, then use what ive learned and teach myself SDL_net ? or,
should i search the net far and wide and teach myself net programming
strait away using SDL_net? what do you think? thanks for any help!
