Go ahead and send it directly to me. I’ll make it available on the SDL site,
in the cvs directory.

Hello,

how can i create a simple 8 Bit Surface with the SDL.

Must i use the CreateRGBSurface funktion??

Thanks

Not really, but it’s probably the easiest way to get it right, by far.

However, what kind of surface do you want? SDL assumes that 8 bit
surfaces are palletized (ie like a VGA Mode 13h screen), whereas 16,
24 and 32 bit surfaces become various forms of TrueColor/HighColor
surfaces.

Also have a look at SDL_CreateRGBSurfaceFrom(), in case you already
have the pixel data ready.

I found that the information “couldn’t create semaphore” was from the file
SDL_syssem.c.
sdl also can manage semaphore,right??

Best regards,
Andy

Hi

I’m working on a framework for a gamingplatform…
Now, ofcourse I have run into som trouble.

I want to have one SDL_Surface that’s the screen, and then have other
"modules" have their own SDL_Surfaces that works like the screen for them.
All those Surfaces are then checked and drawn to the “main” SDL_Surface.
Now, I have the following class:

class SurfaceManager
{
private:
static SurfaceManager* ms_pkInstance;

map m_kSurfaces; <---- This contains a struct that contains some info
about the “virtual” screen and an SDL_Surface*
SDL_Surface* m_pkScreen;

public:
Options kOptions;

SurfaceManager();
SDL_Surface* GetSurface (string kSurfaceName);
bool AddSurface (string kKey, SDL_Surface* kSurface);
bool AddSurface(string kKey, int iWidth = 0, int iHeight = 0, int
iColorDepth = 0);
void SetActiveSurface(string kKey);
void InitSDL();

void Render( float iFrameTime );

SurfaceManager* GetInstance() { return ms_pkInstance; }

};

Does anyone know what 3D Engine Carmageddon is based
on. It doesn’t look like BSP trees. Could it be

Hallo,
I’ve tried to build SDL with Borland C++ Builder using borland.html manual.
When I try to “build all projects” (as it is written in manual) there were
errors, for example: Unable to find package import: clie.bpi.

What should I do? Answer will be welcome.

Greets, how would you create an image with a per-pixel alpha channel?
(that is, not a surface alpha-channel with SDL_SetAlpha.)
I.e. if I’ve already opened an image plus a grey-scale mask image with
SDL_image, then composited them together, how would I alter the format
to accommodate the alpha-components of the pixels?
Any links or source would be appreciated, thanks!

I found an email about this same error in the archives, but no one
responded to it. Wondering if anyone can help me out. On make:

Ok, I actually did solve the problem about a week ago,and did post the
solution, but it may have slipped by rather unnoticed.

Hi,
could anyone help me with this code:
[…]
int end=0;
Uint8 *keys;

while(!end) {
SDL_PumpEvents();
keys=SDL_GetKeyState(NULL);
if(keys[SDLK_ESCAPE] == SDL_PRESSED) end=1;
}

[…] when i compile it using VC6 the loop ends after pressing ESC, but
under Linux where i use gcc 3.2 nothing happens. I also used examples from
libsdl.org but they didn’t work either.

I don’t know if it does any matter but i’m using Gentoo 1.4 with kernel
2.4.22.

Regards Chris

This will work if you first use SDL_Init() and SDL_SetVideoMode() and
then focus the mouse cursor on the new window.–

i dont know if that is a bug or something, but when i use
SDL_GL_GetProcAddress the return function only work one time, at least that
happens with glMultiTexCoord2fARB, when i try to render 2 polygons with
multitexturing only render the first polygon, and the second its a white
polygon, te problem? SDL_GL_GetProcAddress y change it for wglGetProcAddress
and it works fine_________________________________________________________________

This will work if you first use SDL_Init() and SDL_SetVideoMode() and
then focus the mouse cursor on the new window.

The whole code of this simple program is:

#include “SDL.h”

int main(){

int end=0;
Uint8 *keys;
SDL_Surface *screen;

SDL_Init(SDL_INIT_VIDEO);
screen = SDL_SetVideoMode(640,480,16,0);
while(!end) {
SDL_PumpEvents();
keys=SDL_GetKeyState(NULL);
if(keys[SDLK_ESCAPE] == SDL_PRESSED) end=1;
}
SDL_Quit();
return 0;

}

So i use SDL_Init but it still doesn’t work, anyone know why?

I think you said that you use Linux, so compile like this
(where t.c is the name of the source code file):
gcc -I- -I/usr/include/SDL t.c -lSDL> Regard Chris
