Hi everybody,

This is a months work, and it's finally done!

It's a 2D games engin based on GDI+ for graphics and text, and BASS for sound.

It's pretty simple to use, and there is a complete and clear documentation (generated by Natural docs)

I'm lovin' the tank example. Now I can recreate Oregon Trail! I was the hunting master.

Syed23 · August 20, 2011

This awesome and inspiring to do something:)

VisualB · August 20, 2011

stunning awesome code.

5 star

4Eyes · August 20, 2011

This is bloody amazing! I can see many games being built around this. Can't post here what jumped out of my mouth when a started the particle example. :mellow:

Good work! Only 31 posts and 1 month in development?

Incredible nice work! :mellow:

If you could translate the code descriptions to english would be great because my french is absolutely poor!

5* from me!

really awesome! Thanks for sharing! :mellow:

matwachich · August 20, 2011

Thank you every body!

- Only 31 posts because i'm from the french community, and this is my biggest work and i decided to share here!

- I must let the french descriptions for the french users, but the documentation is in english!

- I forgot to tell that the performances are not really good: the greater maximum FPS was 180 for me (Dual core T3400 2.16Ghz, 3Go Ram, Geforce G103M 512Mo), but i think it's enought for some nice little games!

It's not my fault, but it's GDI+.

I tried to do it wit openGL, but i couldn't load textures, so i did it with another programing language (search GL-Engin in google codes, it's in FreeBasic)

Please share any game you make with, i really want to see them!!!

I'm here for any questions!

This is awersome, really good work... thanks for sharing :mellow:

Impressionnant, très bon travail ! (amazing, very good work)

5* from me.

Br, FireFox.

BuckMaster · August 22, 2011

Thanks for creating this engine, its very easy to use and to create new things,

This is the first game I've been making with it, started off with your tank and went from there, probably going to add more in the next couple of days,

One of the only glitches i cant seem to figure out is why they sometimes shoot their selves, but besides that its great

Controls

W - Forward

S - Backwards

A - Left

D - Right

Space - Drop Mine

Hi Buckmaster,

tried your example, but got this result(screenshot).

any clue why?

matwachich · August 22, 2011

They shoot themself because you check the collision between the enemies projectiles and them.

JohnOne · August 22, 2011

matwachich

Your examples are absolutely superb

Thanks for share.

TheGuardian · August 22, 2011

Wow this is amazing, it's simple too.... I like simple :mellow:

Zedna · August 22, 2011

Very nice game engine!! :mellow:

Mobius · August 22, 2011

Bloody hell, Dude this rocks, ran nicely on this crappy old rig too!

5* without a shadow of a doubt. :mellow:

My 2 suggestions:

function _GEng_ImageLoadStream() has a memory leak in worst case scenarios
antialiasing for fonts when aero is enabled

1) use this code instead

;======================================================================================
; Function Name:    Load_BMP_From_Mem
; Description:          Loads an image which is saved as a binary string and converts it to a bitmap or hbitmap
;
; Parameters:           $bImage:    the binary string which contains any valid image which is supported by GDI+
; Optional:                 $hHBITMAP:  if false a bitmap will be created, if true a hbitmap will be created
;
; Remark:                   hbitmap format is used generally for GUI internal images, $bitmap is more a GDI+ image format
;                               Don't forget _GDIPlus_Startup() and _GDIPlus_Shutdown()
;
; Requirement(s):       GDIPlus.au3, Memory.au3 and _GDIPlus_BitmapCreateDIBFromBitmap() from WinAPIEx.au3
; Return Value(s):  Success: handle to bitmap (GDI+ bitmap format) or hbitmap (WinAPI bitmap format),
;                               Error: 0
; Error codes:              1: $bImage is not a binary string
;                               2: unable to create stream on HGlobal
;                               3: unable to create bitmap from stream
;
; Author(s):                UEZ
; Additional Code:    thanks to progandy for the MemGlobalAlloc and tVARIANT lines and
;                               Yashied for _GDIPlus_BitmapCreateDIBFromBitmap() from WinAPIEx.au3
; Version:                  v0.97 Build 2012-04-10 Beta
;=======================================================================================
Func Load_BMP_From_Mem($bImage, $hHBITMAP = False)
    If Not IsBinary($bImage) Then Return SetError(1, 0, 0)

    DllStructSetData($tBIHDR, 4, 1)
    DllStructSetData($tBIHDR, 5, 32)
    DllStructSetData($tBIHDR, 6, 0)
    $hResult = DllCall('gdi32.dll', 'ptr', 'CreateDIBSection', 'hwnd', 0, 'ptr', DllStructGetPtr($tBIHDR), 'uint', 0, 'ptr*', 0, 'ptr', 0, 'dword', 0)
    If (Not @error) And ($hResult[0]) Then
        DllCall('gdi32.dll', 'dword', 'SetBitmapBits', 'ptr', $hResult[0], 'dword', $Ret[2] * $Ret[3] * 4, 'ptr', DllStructGetData($tData, 'Scan0'))
        $hResult = $hResult[0]
    Else
        $hResult = 0
    EndIf
    _GDIPlus_BitmapUnlockBits($hBitmap, $tData)
    Return $hResult
EndFunc   ;==>_GDIPlus_BitmapCreateDIBFromBitmap

You have to adjust the function for your needs appropriatly!

2) besides _GDIPlus_GraphicsSetSmoothingMode() add also DllCall($ghGDIPDll, "uint", "GdipSetTextRenderingHint", "handle", $GFX_Buffer, "int", 4) to activate antialiasing for fonts whereas $GFX_Buffer is the graphic backbuffer.

impressionnant travail, tu as bien dû galérer.

De plus ça tourne sur de vieilles configs, pas mal !

5 étoiles pour moi, without a doubt too.

Hi Buckmaster,
tried your example, but got this result(screenshot).
any clue why?

It worked after conversion to exe... hmm
