do you mean like this line

wvp = XMLoadFloat4x4(&(B.Memory[0].Pieces[35])) * vp;

 

i am sorry i didn't name the variables to be understandable .....B is variable that contains of world matrices of any possible step for the falling small cubes(tetris-like)

it contains of

struct BUILD     //BUILD B;
{
	std::vector <Floor> Memory;
	BUILD(){
		Memory.resize(10);   // i got 10 floors
	}
	UINT GetSize(){
		return Memory.size();
	}
};
struct Floor{
	XMFLOAT4X4 Pieces[36];          //Floor contains 36 possible step
	std::vector <UINT> filledindeces;// contains the indices of the filled matrices
};


//this is how i set the B variable
void Game::SetBuild(){
	float x=0,y=0,z=0;
	XMMATRIX tMat;
	Floor tFloor;//temporary varaible to set floor matrices one by one
	UINT re = B.GetSize(); //B is a member variable
	for (UINT i = 0; i < re ; i++)
	{
		x=0;z=0;
		for (int j = 0; j < 36; j++)
		{
			tMat = XMMatrixTranslation(x,y,z);
			XMStoreFloat4x4(&tFloor.Pieces[j],tMat);
			if (j == 35)
			{
				y+= heightoff;  // hieghtoff = height / 10
				x=0;
				z=0;
				continue;
			}
			if ((j+1) % 6 == 0)
			{
				x -= widthoff; //widthoff = width / 6
				z = 0;
				continue;
			}
			z -= depthoff; //depthoff = depth / 6
		}
		B.Memory[i]=tFloor;
	}
	B.Memory[9].filledindeces.push_back(10); //drop a box from the 10th floor at index 10
	currentItem.Floor_Index=10;
//currentItem is a member variable for tracking the currently falling box to move it when the user press buttons
	currentItem.Height=9;
}
 

well i didn't mention it because i am sure there is no problem here

....those matrices are already constant i call setBuild() in the first initializations ..... i dont change them at all .....

i already tried something .....i patched the program to never call onResize() and it works except that it is low quality....low quality problem is easy to solve(increasing resolution)...but that means i need to patch it also to be unable to resize window...the problem is kind of fixed....that means the problem where on resize function...isn't there any kind of rules or special condition (like releasing the buffers before calling swapchain->resizebuffers())...
