Feedback --- FB.11 and GFX

[ShadowWolf]

ok here a simple pure sdl example for you ray.

Code:

option explicit

'$include: "sdl\sdl.bi"

declare sub plot (surfacetemp as sdl_surface ptr,byval x as integer ,byval y as integer,byval R as UBYTE ,byval G as UBYTE,byval B as UBYTE)
Dim result as unsigned integer


result = SDL_Init(SDL_INIT_EVERYTHING)
    if result <> 0 then
          SDL_Quit
       end 1
   end if
  
dim surface1 as sdl_surface ptr
dim x as integer
dim y as integer

dim R as ubyte
dim G as ubyte
dim B as ubyte

surface1 = SDL_SetVideoMode(1280, 1024, 32,SDL_HWSURFACE or SDL_DOUBLEBUF or sdl_fullscreen)

SDL_LockSurface (surface1)
for x = 1 to 1280
   for y = 1 to 1024
      R = X+Y : R = R mod 200
      G = Y-r : G = G mod 200
      B = X+G   : B = B mod 200
    plot surface1,x,y,R,G,B
   next
  next
sdl_Unlocksurface (surface1)


sdl_flip surface1
sleep 1000
sdl_quit
end

sub plot (surfacetemp as sdl_surface ptr,byval x as integer ,byval y as integer, byval R as UBYTE ,byval G as UBYTE,byval B as UBYTE)
dim colkey as uinteger
  colkey = SDL_MapRGB (surfacetemp->format, R, G, B)
  
      dim cl_32bit as uinteger ptr
      cl_32bit = surfacetemp->pixels + y * surfacetemp->pitch + x * len( integer )
      *cl_32bit = colkey
end sub

RTFM applies perfectly here. It's at docs/gfxlib.txt, if you can't find it, here is the SCREEN description:

Code:

+--------+--------------------------------------------------------------------
| SCREEN |
+--------+

Statement to set current gfx mode.


Syntax:
    SCREEN mode[,[depth][,[num_pages][,fullscreen]]]


Argument:    Description:

mode        Gfx mode number, see below.

depth        Color depth in bits per pixel. If you omit this argument, the
        default depth for given mode is set.

num_pages    Number of pages, see below. Default if omitted is 1.

fullscreen    Set this argument to 0 to request a windowed mode, 1 to
        request a fullscreen mode. Default if omitted is 0.

If you can't understand simple instructions like Angelo wrote in gfxlib.txt, forget about programming, open up MS-Paint and your problems are over.

And you need to go back to grade 1 and learn to read -- I was talking about sdl not GFX.

Ray, maybe v3cz0r was answering one of the questions where you really were talking about GFX, like this one:

Fb 0.11 will still not open a full window with
'$inlude: "sdl\sdl.bi"
screen 1024, 768,8,1
it does in Fb 0.1
If I am missing some code to correct this them I'm listening
Ray.

That looks like a GFX question to me, not an SDL question. "screen" is a GFX command, not an SDL function.

v3cz0r's post shows you the reason why screen isn't opening a full window. It's because the syntax for the screen command changed from 0.10 to 0.11.

No need to be rude or insulting, ok?

You only flip once you've drawn all the gfx for that frame.

Flipping after only a single dot is being drawn is extremely wasteful, and will result in your program being slower than it would normally be.

Also, if you use SDL_Flip, make sure to implement a delay, or only flip a certain amount of times per second. Ptherwise your program will suck up 100% CPU, and will slowdown to a crawl.
Use SDL_GetTicks, to get a very highresolution timer (much better than TIMER)
I use SDL_GetTicks, and only flip once every 25th tick (millisecond which gives a nice smooth 40FPS


To get keypresses in SDL:

Code:

dim shared key as ubyte ptr
key = SDL_GetKeystate(0)
Do
SDL_PumpEvents 'enables the user to press keys, and move the window etc.
'Always pump events, especially if you want mouse or keyboard to work properly


If Peek(key + SDLK_ESCAPE) Then
  'Escape was pressed
   Exit Do
End If
Loop

Then I just decided to ignore this topic. Be more specific please rayjohn01

Rayjohn: Have some fucking decency (GODDAMN FUCKING CENSORSHIP). These people are helping you FOR FREE and have written AMAZING software FOR FREE.

READ THE FUCKING MANUAL

I suggest no one reply to him in any thread similar to this. Just stop talking to him and maybe he will stop being a complete and utter jackass.
