Why sprites render over objects?

Question

I want to render a cube on a picture like in this tutorial. Problem is that it renders only the picture and the cube doesn't render. Can you help me ? Thankyou

m_spriteBatch->Begin();
m_spriteBatch->Draw(m_background.Get(), m_fullscreenRect);

//
// Clear the back buffer
//
g_pImmediateContext->ClearRenderTargetView( g_pRenderTargetView, Colors::MidnightBlue );

g_pImmediateContext->ClearDepthStencilView(g_pDepthStencilView, D3D11_CLEAR_DEPTH, 1.0f, 0);

g_pImmediateContext->OMSetRenderTargets(1, &g_pRenderTargetView, g_pDepthStencilView);


//
// Update variables
//
ConstantBuffer cb;
cb.mWorld = XMMatrixTranspose( g_World );
cb.mView = XMMatrixTranspose( g_View );
cb.mProjection = XMMatrixTranspose( g_Projection );
g_pImmediateContext->UpdateSubresource( g_pConstantBuffer, 0, nullptr, &cb, 0, 0 );

//
// Renders a triangle
//
g_pImmediateContext->VSSetShader( g_pVertexShader, nullptr, 0 );
g_pImmediateContext->VSSetConstantBuffers( 0, 1, &g_pConstantBuffer );
g_pImmediateContext->PSSetShader( g_pPixelShader, nullptr, 0 );
g_pImmediateContext->DrawIndexed( 36, 0, 0 );        // 36 vertices needed for 12 triangles in a triangle list

//
// Present our back buffer to our front buffer
//
m_spriteBatch->End();
g_pSwapChain->Present( 0, 0 );

SpriteBatch batches up draws for performance, so it's likely being drawn after the cube draw. If you want to make sure the sprite background draws first, then you need to call End before you submit your cube. You also need to call Begin after you set up the render target:

// Clear
g_pImmediateContext->ClearDepthStencilView(g_pDepthStencilView, D3D11_CLEAR_DEPTH, 1.0f, 0);
g_pImmediateContext->OMSetRenderTargets(1, &g_pRenderTargetView, g_pDepthStencilView);

// Draw background image
m_spriteBatch->Begin();
m_spriteBatch->Draw(m_background.Get(), m_fullscreenRect);
m_spriteBatch->End();

// Draw objects
context->OMSetBlendState(…);
context->OMSetDepthStencilState(…);
context->IASetInputLayout(…);
context->IASetVertexBuffers(…);
context->IASetIndexBuffer(…);
context->IASetPrimitiveTopology(…);

You can omit the ClearRenderTargetView if the m_background texture covers the whole screen.

For more on how SpriteBatch draw order and batching works, see the wiki.

Thankyou for answering so fast. I did all you said but it's not working, I mention that I draw the object like in this example (https://msdn.microsoft.com/en-us/library/windows/apps/ff729722.aspx), not using shape draw. – warriorforce Oct 23 '18 at 20:11
I think it's related to this, I am not sure https://gamedev.stackexchange.com/questions/31616/spritebatch-begin-making-my-model-not-render-correctly – warriorforce Oct 23 '18 at 21:09
Your answer here [link](https://stackoverflow.com/questions/35558178/directxspritefont-spritebatch-prevents-3d-scene-from-drawing) is related to this, but I can't figure it out. – warriorforce Oct 23 '18 at 21:47

Based on this answer by @ChuckWalbourn I fixed the problem.

 g_pImmediateContext->ClearRenderTargetView( g_pRenderTargetView, Colors::MidnightBlue );


g_pImmediateContext->ClearDepthStencilView(g_pDepthStencilView, D3D11_CLEAR_DEPTH | 

D3D11_CLEAR_STENCIL, 1.0f, 0);


m_spriteBatch->Begin();
m_spriteBatch->Draw(m_background.Get(), m_fullscreenRect);
m_spriteBatch->End();

states = std::make_unique<CommonStates>(g_pd3dDevice);
g_pImmediateContext->OMSetBlendState(states->Opaque(), Colors::Black, 0xFFFFFFFF);
g_pImmediateContext->OMSetDepthStencilState(states->DepthDefault(), 0);
// Set the input layout
g_pImmediateContext->IASetInputLayout(g_pVertexLayout);
UINT stride = sizeof(SimpleVertex);
UINT offset = 0;
g_pImmediateContext->IASetVertexBuffers(0, 1, &g_pVertexBuffer, &stride, &offset);
// Set index buffer
g_pImmediateContext->IASetIndexBuffer(g_pIndexBuffer, DXGI_FORMAT_R16_UINT, 0);

// Set primitive topology
g_pImmediateContext->IASetPrimitiveTopology(D3D11_PRIMITIVE_TOPOLOGY_TRIANGLELIST);

// Draw objects

I'd recommend not creating a new ``CommonStates`` object every frame. Creating Direct3D resource objects can be expensive, so you don't want to do it 60+ times a second if you don't need to. Make it a member variable like you have ``SpriteBatch``, etc. — Chuck Walbourn, Oct 24 '18 at 00:33
Ok, thankyou for your help. Btw, do you think I can get the same effect using firect composition ? — warriorforce, Oct 24 '18 at 15:01
