IrrDelphi(Irrlicht 172, irrKlang 130b) Delphi\Pascal headers

[wlion]

There is another memory leak in Irrlicht_172.pas :

Code: Select all

SMaterialLayer  = record
..........
   TextureMatrix: Pmatrix4;    // <== may be change to "TextureMatrix: matrix4; " can prevent memory leak
..........
end;

Code: Select all

procedure SMaterialLayer.setTextureMatrix(const vMat: Pmatrix4);
begin
  if not Assigned(TextureMatrix) then begin
    New(TextureMatrix);       // <== will cause memory leak, only create, no dispose
    TextureMatrix^ := vMat^;
  end else
    TextureMatrix^ := vMat^;
end;

I have a couple of memory leaks in the example 12:

Code: Select all

i'm trying to fix this problems

[RainBoy]

I've finished change part of code to prevent memory leaks
Please note that i've changed parts that really needed to me; this wrapper still have several 'memory leaks' routines.

Changed:

- Replace function IrrStr to procedure IrrStr;
Now you need to write something like this -

Code: Select all

strTerMap : PIrrString;
strTerMap := new(pIrrStringA);
irrStr('media\terrain-heightmap.bmp', strTerMap);
//.... working with strTermap
Dispose(strTerMap);


- Added TVMTManager class to calculate allocated memory in PatchVMTbyVMT procedure

It is possible that other examples should not work now; you need to change works with irrStr procedure.
Now i don't have any memory leaks in Example 12 - Terrain rendering.

You can download it here - http://dl.dropbox.com/u/3790498/irrlicht/Irrlicht_Test.7z

Thank you,
Alex.

small fix
Irrlicht_172.pas line 12017

Code: Select all

function createDeviceEx(const parameters: SIrrlichtCreationParameters): PIrrlichtDevice; cdecl; external IRR_DLL;


params must be passed by ref

Code: Select all

   extern "C" IRRLICHT_API IrrlichtDevice* IRRCALLCONV createDeviceEx(
      const SIrrlichtCreationParameters& parameters);


update to

Code: Select all

const parameters: PSIrrlichtCreationParameters

test

Code: Select all

function DeviceCreate(const deviceType: E_DRIVER_TYPE; const w, h, bits: Integer; const fullscreen, stencilbuffer, vsync: Boolean; const receiver: Pointer = nil): PIrrlichtDevice;
var
  params: SIrrlichtCreationParameters;
begin

  params.DeviceType := EIDT_BEST;
  params.DriverType := deviceType;
  params.WindowSize.Width := w;
  params.WindowSize.Height:= h;
  params.Bits := bits;
  params.ZBufferBits := bits;
  params.Fullscreen := fullscreen;
  params.Stencilbuffer := stencilbuffer;
  params.Vsync := vsync;
  params.AntiAlias := 0;
  params.WithAlphaChannel := false;
  params.Doublebuffer := true;
  params.IgnoreInput := false;
  params.Stereobuffer := false;
  params.HighPrecisionFPU := false;
  params.EventReceiver := receiver;
  params.WindowId := 0;
  params.LoggingLevel := ELL_INFORMATION;
  params.SDK_version_do_not_use := IRRLICHT_SDK_VERSION;

  result := createDeviceEx(@params);
  // get irrlicht imagebase for thiscall_ex
  IRR_IMAGEBASE := GetModuleHandle(IRR_DLL);
  // default
  dev := Result;
  if Assigned(dev) then begin
    drv     := dev.getVideoDriver;
    fs      := dev.getFileSystem;
    gui     := dev.getGUIEnvironment;
    smgr    := dev.getSceneManager;
    cur     := dev.getCursorControl;
    logger  := dev.getLogger;
    vidml   := dev.getVideoModeList;
    osop    := dev.getOSOperator;
    tmr     := dev.getTimer;
  end;
end;


and maybe rename deviceType to driverType?

IXMLReader not implemented. please implement it...

[RainBoy]

Looks like this project does not have any support now...
I have a strange problem.
I'm using code similar to the terrain sample.
My project creates terrain, shows it. After that user closes this view (all objects disposed) and reopen new terrain
I can open terrain 1 time without any problem, but when i tried to reopen other terrans 2..6 times my application crashes with "problem in external dll at address...."
Someone has the same problem? Dn how i can fix it...

Irrlicht 172 latest version now.. no updates for headers. Attach source

IXMLReader not implemented. please implement it...

Can't do this.. IXMLReader used c++ language fithes which Delphi not have

small fix

Not necessary becouse it identical

and maybe rename deviceType to driverType?

Sure

[RainBoy]

check your PM please -)

irrDelphi, please check your PM again

sorry about some flood, guys =)

Hi,
I've got a question. How I should drop the ,,engine" from the irrKlang demos.

cpp Code: Select all

 
drop_gcc(engine); // delete engine
 

In the irrKlang_130b is no drop_gcc

[Römer123]

Here is the answer:

cpp Code: Select all

 
irrKlangDrop(engine);
 

[IrrDelphi]

I've got a question. How I should drop the ,,engine" from the irrKlang demos.

Gcc version is experimental and buggy! Use vc version and irrKlangDrop() function

Hi IrrDelphi,

is possible to use headers with Freepascal on Mac OSX?

Thanks in advance

No, Windows only
