SDL UDF

[AdmiralAlkex]

Ladies, gentlemens, nerds or whatever you are, I present to you, my SDL UDF!

Q. So what is this then?

A. It is a "wrapper" for the SDL.dll and some "help libraries" to make it easier to use in AutoIt.

Q. WTF is SDL?

A. As their webpage says: "Simple DirectMedia Layer is a cross-platform multimedia library designed to provide low level access to audio, keyboard, mouse, joystick, 3D hardware via OpenGL, and 2D video framebuffer."

Q. Can it really do all that?

A. No. I have implemented many functions, but not all. I will update it on my own discretion.

Q. So what does WORK?

A. See the table below.

Q. So how do I use it?

A1. Read README.TXT in the archive.

A2. There is a few examples in the download, study them.

A3. Find any example or documentation for another language and translate it (shouldn't be to hard).

Q. So where's the download?

A. Next post.

Some screenshots:

(notice the transparent Opera/AutoIt png image)

Bugs:

• The _SDL_*Color() draw strange colors (_SDL_*RGBA() works fine).
• See notes in scripts for more details and broken functions.

ToDo:

Lots.

Q. What licence does it use?

A. Read README.TXT in the archive.

Download:

SDL v14 ½.zip

(previous downloads= ???+117+68+40+9+5)

sounds great, maybe you can force development a bit in the direction of threads and 2d framebuffer

just as a little hint ;P

[AdmiralAlkex]

Well I am not sure how to even begin with the threads, or what they would be useful for. 2d graphics would be great, I just need to get alot better at structs and that kind of stuff unless some kind person want to help some

[AdmiralAlkex]

YES!!

I have managed to both read and draw single pixels + draw rectangles + load and draw BITMAPS!! (monoceres helped alot).

Preliminary speed tests are quite good too.

I will release a big update as soon as I get some functions to draw primitives to work + have written some examples.

[JRSmile]

sounds great, looking forward to hearing from you

[AdmiralAlkex]

I just uploaded v6. The include have about 2.5 times the lines of code with about 3 times the functions. It now totals 1379 lines/160 funcs.

You will notice alot of video functions implemented + the SDL_gfx.dll for drawing alot of prototypes (uninteresting fact, there are 5 functions for drawing a filled box, 1 from SDL, 2 from me, 2 from gfx).

I also implemented most of the "window management" functions, even the most worthless ever: SDL_WM_ToggleFullScreen (a cookie to the one who knows why).

Edit: Oh yeah, the initialization routines changed so old scripts will not work without modifications.

I have to say this is a Great UDF!

And here is the working WM_GetCaption

expandcollapse popup

Func _SDL_WM_GetCaption()
    Local $aResult = DllCall($__SDL_DLL, "none:cdecl", "SDL_WM_GetCaption", "ptr*", 0, "ptr*", 0)
    Local $aTemp[2]=[__SDL_PtrStringRead($aResult[1]), __SDL_PtrStringRead($aResult[2])]
    Return $aTemp
EndFunc

    Local $Ret = DllCall("kernel32.dll", "int", "lstrlen" & $UniCodeFunc, "ptr", $ptr)

    If $StringLen < 1 Then Return SetError(1, 0, "")
    Local $struct = DllStructCreate($UniCodeString & "char[" & ($StringLen + 1) & "]", $ptr)
    Return DllStructGetData($struct, 1)
EndFunc   ;==>__SDL_PtrStringRead

I also implemented most of the "window management" functions, even the most worthless ever: SDL_WM_ToggleFullScreen (a cookie to the one who knows why).

It is just worthless for Windows. This functions works on *nix with X11

//Edit: Yeah i got the cookie. Thanks. I WANT MORE

I have to say this is a Great UDF!

And here is the working WM_GetCaption

Thank you ProgAndy, but I just get a empty string? Do you have a working example so I can see what I am missing?

Right, and AutoIt is for windows, soo it's totally pointless.... here you go

- [insert picture of enormous cookie here] -

Edit: Oh I get it, WM_GetCaption only returns something if you changed from the default first

Edit2: I will include you code in the next update

Update uploaded.

Changes:

Implemented _SDL_WM_GetCaption() posted by ProgAndy

Split include into one file for each dll and rearranged the regions.

Changed initialization routines.

Implemented functions/macros/vars from version.h, cpuinfo.h, error.h and timer.h

Lots of other "minor" stuff too....

[JRSmile]

thanks for your hard work alredy done at this project already using it :-) but maybe you could adapt the examples to work with the current release ?

Which examples are you referring to?

Edit1: Oh right, I forgot to update the examples in the archive . I will fix that in the next update (should be tonight or tomorrow) but until then you can safely change line #11 to "#Include "SDL v8.au3"" and it will work. Joystick and CDROM funcs have not been changed since the initial release.

Edit2: And add #include "SDL_gfx v1.au3" to the other one....

New update uploaded.

Added Mutexes

Added SDL_image.dll

This makes it possible to very easily use jpg and many other formats, including transparent png.

Added new example that shows how to use SDL_image + DirectX.

Please note that DirectX is considered unstable (that's why SDL is using Windib by default). Also it's only using hardware acceleration when using fullscreen (I think).

Please note that neither of this should be any problem, Windib is usually more than enough for 2D graphics.

Edit1: I just noticed the download was missing 2 files, it will be fixed in a minute.

Edit2: Fixed.

[TomCat]

can you give me a hint how to use SDL_WarpMouse() and SDL_GetMouseState() ?

[AdmiralAlkex]

@TomCat

Sure, here you have:

(attachments removed, they have been included in sdl.zip for a long time)

SDL_Example_WarpMouse.au3 (1.05K)

Number of downloads: 231

SDL_Example_Get_Relative_MouseState.au3 (2.03K)

Number of downloads: 214

While writing the examples I saw that all 3 of them (including GetRelative...) wasn't working as intended, but in the bottom of the examples is the fixed functions. The fixes (and probably the examples) will be in the next update.

it works well some next question ^^ is it also possible to use this functions also in some games ? and if yes how ?^^

Do you mean you want to use them in a window not created by the script itself? Like a bot for Diablo2? If so then I am afraid the answer is no, SDL doesn't have that functionality for the simple reason that it was created to build cross-platform multimedia apps, not controlling windows in Windows (that sounded weird). You probably need MouseMove() and MouseGetPos(). Edited May 29, 2009 by AdmiralAlkex

[Zisly]

Wow, this sounds nice!

I'll check it out for sure, nice work!

[AdmiralAlkex]

Here is a example that creates a AutoIt gui and then uses SDL to draw a transparent PNG as a background.

P.S. A cookie to the one who knows where the quotes in the MsgBox is from

SDL_Example_Transparent_PNG_on_AutoIt_GUI.au3 (1.55K)

My guess is Starcraft?

Also, thanks for this UDF! Amazing! I'm loving AutoIt more and more as I browse these forums.
