1. ## create 2 index buffer

the article say "Make 2 buffers", can u post the code, i can't imagine it . If there is 1 buffer set. Thankyou so much, i have tried but its all blank screen.
2. ## create 2 index buffer

thankyou . d3d11DevCon->IASetIndexBuffer( squareIndexBuffer1, DXGI_FORMAT_R32_UINT, 0);     d3d11DevCon->IASetIndexBuffer( squareIndexBuffer2, DXGI_FORMAT_R32_UINT, 0);   the second index buffer set  to the IA stage require the offset, how can we get the size of the first buffer ?
3. ## create 2 index buffer

hi there, ive just read the following tutorial http://www.braynzarsoft.net/index.php?p=D3D11INDICES And i started do the exercise 1. Make 2 index buffer.    Vertex v[] = { Vertex( -0.5f, -0.5f, 0.5f, 1.0f, 0.0f, 0.0f, 1.0f ), Vertex( -0.5f, 0.5f, 0.5f, 0.0f, 1.0f, 0.0f, 1.0f ), Vertex( 0.5f, 0.5f, 0.5f, 0.0f, 0.0f, 1.0f, 1.0f ), Vertex( 0.5f, -0.5f, 0.5f, 0.0f, 1.0f, 0.0f, 1.0f ), Vertex( 0.0f, 1.0f, 0.5f, 0.0f, 1.0f, 0.0f, 1.0f ), }; DWORD indices1[] = { 0, 1, 2, 0, 2, 3, }; DWORD indices2[] = { 1, 2, 4 }; D3D11_BUFFER_DESC indexBufferDesc; ZeroMemory( &indexBufferDesc, sizeof(indexBufferDesc) ); indexBufferDesc.Usage = D3D11_USAGE_DEFAULT; indexBufferDesc.ByteWidth = sizeof(DWORD) * 2 * 3; indexBufferDesc.BindFlags = D3D11_BIND_INDEX_BUFFER; indexBufferDesc.CPUAccessFlags = 0; indexBufferDesc.MiscFlags = 0; D3D11_SUBRESOURCE_DATA iinitData; //D3D11_SUBRESOURCE_DATA iinitData2; iinitData.pSysMem = indices1; d3d11Device->CreateBuffer(&indexBufferDesc, &iinitData, &squareIndexBuffer1); indexBufferDesc.Usage = D3D11_USAGE_DEFAULT; indexBufferDesc.ByteWidth = sizeof(DWORD) * 1 * 3; indexBufferDesc.BindFlags = D3D11_BIND_INDEX_BUFFER; indexBufferDesc.CPUAccessFlags = 0; indexBufferDesc.MiscFlags = 0; iinitData.pSysMem = indices2; d3d11Device->CreateBuffer(&indexBufferDesc, &iinitData, &squareIndexBuffer2); d3d11DevCon->IASetIndexBuffer( squareIndexBuffer1, DXGI_FORMAT_R32_UINT, 0); d3d11DevCon->IASetIndexBuffer( squareIndexBuffer2, DXGI_FORMAT_R32_UINT, 0);   And the questions are: 1.i use the same D3D11_BUFFER_DESC and D3D11_SUBRESOURCE_DATA to create 2 Index buffer ( adjust the fied of D3D11_BUFFER_DESC ) Is it possible? 2. the function d3d11DevCon->IASetIndexBuffer(). i so confuse about the third parametter, how can we know the offset? Thankyou

thank for reading my topic. When i create object of myTank in main function, and render it. All things work. but when i create object of TankGame in main function( it include instance of mytTank, it call constructor of m_player, and in debug mode, it goes to the end of TankGame constructor ( in this case, it created myTank object ),it raise "error Run-Time Check Failure #0" here script is an singleton class, and i tested it, it worked.

Hello guys, i have problem with my code tankGame.h [CODE] class myTank; class TankSteering; //enum KEYS{ W, S, A, D,J,K}; class TankGame{ public: TankGame(ALLEGRO_DISPLAY* display); ~TankGame(); myTank* m_player; TankSteering* m_TankSteering; void Update(); void Render(); }; [/CODE] myTank.h [code] class TankGame; class TankSteering; class myTank : public MovingEntity { public: myTank(TankGame* tank_game, Vector2D pos, ALLEGRO_DISPLAY* display); ~myTank(); void Update(); void Render(); ....blah.... private: ....blah.... TankSteering* m_pSteering; TankGame* m_tankGame; }; [/code] tankSteering.h [code] class myTank; class TankGame; class TankSteering { public: TankSteering(myTank* player, TankGame* tankGame); //TankSteering(); ~TankSteering(); Vector2D Calculate(); Vector2D Player_Steering(); private: TankGame* m_pTankGame; float m_fMaxForce; myTank* m_tplayer; float m_fDesRateForce; }; [/code] TankGame.cpp [code] TankGame::TankGame(ALLEGRO_DISPLAY* display) { m_player = new myTank(this, Vector2D(200.0f, 200.0f), display); //m_TankSteering = new TankSteering(this); for(int i = 0; i < 6; i++) { keys[i] = false; } } blah blah [/code] the thing is, when i remove the line "m_player = new myTank(this, Vector2D(200.0f, 200.0f), display);" in my tankGame, it work. But when i add this line in TankGame constructor, error "error Run-Time Check Failure #0" happened. when i create an object of myTank in mainfunction, it worked. Someone can help me [img]http://public.gamedev.net//public/style_emoticons/default/smile.png[/img]. Thank in advance
