I can't run my game in release mode. It runs until one point. I think the error has something to do with pointers. I have a class cPlayer; like

    

cPlayer P[20];

cPlayer *DrawP[10];
cPlayer *TempP;

DrawP[x] = &P[x]; //take all the players that should be drawn


TempP = DrawP[x]; //this is how I use this TempP


//And then I use the DrawP to sort and then draw the players

It's not pasted from the code. But it's about the way it's done in It works in debug but not in build

What could it be?? /MindWipe

Didn''t help

I forgot to say that I call the draw function with the pointers

DrawP[x]->Draw(...);

Ah, the infamous release mode crash... works OK with debug build, right? This is commonly caused by buffer overruns. Also, turn off compiler optimizations for release build and see what happens.

I would like to comment that the logical expression you presented can be simplified.

Resist love = 0 OR 1
die = 1 (you gonna die anyway).

Resist love OR die = Resist love OR 1 = 1.

So you could just put the expression 1.

Well.. this is really odd.

I traced the error to a blit. Yup. One blit makes it crash.

I have a Player.Draw(...)
that blits a shadow, the players legs, body and head (4 blits)
And it''s when I blit the legs it crashes!!

It works in debug. And how the hell could this cause a crash?

  
bool cGfx2d::Blit(int x, int y, DWORD Sprite, RECT *rcSrc)
{
	HRESULT		hr;

	if(sprite[Sprite].Allocated == false) return false;
	if(lpDD == NULL) return false;
	if(Sprite == NA) return false;

	//seems okey - let''s blit

	hr = lpDDSBack->BltFast(x ,y, sprite[Sprite].Surface, rcSrc, DDBLTFAST_SRCCOLORKEY);
	
	//Don''t detect other errors. They won''t bother us

	if(hr == DDERR_SURFACELOST)
	{
		LOG("[GFX::Blit] Error Surface Lost %s\n",sprite[Sprite].FileName);
		return false;
	}

	return true;
}

That''s my blit

Taced the error even closer. It''s one surface that makes it crash. If I use the same parameters except for the surface it works. How can that be?

PHEW!!!! Found the error.

It was when it loaded the legs-surfaces.

I had writeen:

  
char ImageToLoad[16];

memset( ImageToLoad, 0, sizeof( ImageToLoad ) );
sprintf( ImageToLoad, "PlayerGFX\\legs%d_%d.bmp", a + 1, b + 1 );
Legs[a]http://[b] = Gfx()->LoadSprite( ImageToLoad, ck );

16 characters isn´t enough. But it seemed to work in debug still.
But now it's fixed!

Damn this is GRRRRRRRRRREAT
