SDL UDF

[AdmiralAlkex]

Silly me

For anyone that saw this comment:

Note1 = The _SDL_*Color funcs doesn't paint the right colors.

You can safely IGNORE IT.

I was only testing it the wrong way. It works fine if you use 0xRRGGBBAA

To make a solid red, use :0xFF0000FF

To make a solid green, use :0x00FF00FF

To make a semi-transparent blue, use :0x0000FF80

@ALL

I have been experimenting with something that would greatly simplify distribution for the UDF.

The idea is to have the dll file included as binary in the include, and in the beginning of the *Init() func, check if the file exist and create it if it doesn't.

This would mean that you would never have to package any dll, and the total filesize would be smaller (in compiled form).

Working with source would be easier too. Copy include and you're done!

What do you think?

Makes sense?

Doesn't make sense?

Am I crazy?

Am I hungry? (actually yes I am)

Here's something for you to test so you see what I mean:

1. Download the updated SDL.au3

2. Download the "blob" containing the dll

3. Run a test script, like this:

#include "SDL.au3"
ConsoleWrite("FileExist(SDL.dll) says: " & FileExists("SDL.dll") & @CRLF)
_SDL_Init($_SDL_INIT_EVERYTHING)
ConsoleWrite("FileExist(SDL.dll) says: " & FileExists("SDL.dll") & @CRLF)
_SDL_Quit()

4. Pay attention to the ConsoleWrite. Neat, right?

(attachment removed, it's worthless without the "blob" (damn upload site that keeps deleting my files for no obvious reason), if it isn't in the next release, you could probably rebuild it in minutes anyway, or just ask me for the code)

Hello everybody,

need to know how to send the push of a button on the joystick, because the game "street fighter 4" player 2 has no controls on the keyboard.

Someone help me know?

@jcval

SDL can't do that, it's for creating games, not automating them.

Obrigado,

mas você tem alguma idéia de como fazê-lo?

thanks,

but you have any idea how to do it?

[AdmiralAlkex]

thanks,

I'm sorry, but no, I don't.

If I am using _SDL_GuiCreate to construct a gui, how do I reposition the gui to the center of my screen? Currently, it is in the top left hand corner.

[AdmiralAlkex]

You could set where the window should be created by setting the environment variable "SDL_VIDEO_WINDOW_POS", like this:

EnvSet("SDL_VIDEO_WINDOW_POS", 0 & ", " & 0)

The first number is X, and second Y. Don't forget the comma between them. Note that SDL read the environment variables when you do _SDL_Init(), so set them before that or nothing will happen.

Then there's always WinMove() (but that wouldn't look good, would it?) or you could create a normal AutoIt window and let SDL use that with SDL_WINDOWID. See the script "SDL Example Transparent PNG on AutoIt GUI.au3" for that.

And remember, controls ARE windows, so you could create a label or something, get it's handle and pass that to SDL_WINDOWID.

Just get the sizes right or things will get really weird.

Big EDit:

I was a bit bored so I wrote this half-crazy example:

expandcollapse popup

#Region ;**** Directives created by AutoIt3Wrapper_GUI ****
#AutoIt3Wrapper_UseX64=n
#EndRegion ;**** Directives created by AutoIt3Wrapper_GUI ****
#Include "SDL.au3"


Local $GX = 640, $GY = 480
$hWnd = GUICreate(@ScriptName, $GX, $GY, 0, 0)
EnvSet("SDL_WINDOWID", $hWnd)
_SDL_Init($_SDL_INIT_VIDEO)

$pSurface = _SDL_SetVideoMode($GX, $GY, 0, $_SDL_SWSURFACE)     ;Just for some variation
_SDL_FillRect($pSurface, 0, 0xFF0000)
_SDL_Flip($pSurface)
GUISetState()

Do
    Sleep(10)
Until GUIGetMsg() = -3
_SDL_Quit()
GUIDelete($hWnd)


Local $GX = 320, $GY = 240
$hWnd = GUICreate(@ScriptName, $GX*2, $GY*2, @DesktopWidth/2 - $GX, @DesktopHeight/2 - $GY)
$hWnd2 = GUICtrlGetHandle(GUICtrlCreateLabel("", 30, 10, $GX, $GY))
EnvSet("SDL_WINDOWID", $hWnd2)
_SDL_Init($_SDL_INIT_VIDEO)

$pSurface = _SDL_SetVideoMode($GX, $GY, 0, $_SDL_SWSURFACE)     ;Just for some variation
_SDL_FillRect($pSurface, 0, 0x00FF00)
_SDL_Flip($pSurface)
GUISetState()

Do
    Sleep(10)
Until GUIGetMsg() = -3
_SDL_Quit()
GUIDelete($hWnd)


Local $GX = 640, $GY = 480
EnvSet("SDL_WINDOWID", "")
EnvSet("SDL_VIDEO_WINDOW_POS", @DesktopWidth -$GX & ", " & @DesktopHeight -$GY)
_SDL_Init($_SDL_INIT_VIDEO)

$pSurface = _SDL_GuiCreate(@ScriptName, $GX, $GY, 32, $_SDL_SWSURFACE)
_SDL_FillRect($pSurface, 0, 0x0000FF)
_SDL_Flip($pSurface)

While 1
    Sleep(10)
WEnd

Please note that that script doesn't seem to close itself properly sometimes (not sure why) so you may want to check your task manager after running it.

AdmiralAlkex, Neither links are working for me.

AdmiralAlkex, Neither links are working for me.

The one on post #44 works for me. Maybe it was just temporarily "confused", please try to click it again.

[yehia]

is there anyway to flip an image?

like flipping it horizontally ...

it would save some time and effort

thanks

[AdmiralAlkex]

@yehia

Sorry buddy, missed you there a couple of days.

SDL_gfx can flip a surface, see description on the official website (do a search in page for "Rotozoomer").

Edited May 20, 2010 by AdmiralAlkex

[yehia]

yes thanks a lot

the function is _SDL_rotozoomSurfaceXY if anyone searched for this later

[yehia]

any chance for the support of animated gifs?

[AdmiralAlkex]

Well no, not from me anyway. I wouldn't even know where to begin.

How would you expect that to work anyway? Every frame gets loaded to separate surfaces? Wouldn't it be just as easy (and use less disk-space) to use multiple .png files?

[yehia]

i found a dll somewhere yesterday for that but still the idea itself seemed stupid where the gif is going in a direction and the whole script using another timing

i dont know but it seemed illogical

thanks for the help again

[Pottery]

Can someone update the link lol

[AdmiralAlkex]

Did you try the link at post 44 as told? It works for me.

http://hem.passagen.se/amax/autoit/SDL%20v14½.zip

[Delta]

I'm getting an error from both links.

The second one from post 44 is giving me this.

Ignore the popup, the linked page should start the download. You could try downloading with another browser.

Some extra mirrors:

Some Swedish file upload site

My desktop (online at random times)

I have intentions to create a more "permanent" solution, but that will not happen right now.

It's pizza time!
