  1. problem initializing Direct 3d Device

    Thanks a lot for sparing your time on this and for editing my code. Now the code works after making some changes. Also, one of the problems with the earlier one was i missed a call statement to drawscene() but not able to understand why "the device not initialized" error occurred because even in the earlier code ,the device initialization was done in graphics class and i just called a function from game class passing HWND parameter. Thanks again i really appreciate it, spent almost two weeks trying to figure out.

    Thanks for ur response

  5. Making a game from scratch

    i just need a simple book showing the way game is made from scratch
  6. Making a game from scratch

    hello i am planning to make a game from scratch using c++ with directx9 and i have experience making games using other's engine in directx. Can anyone suggest me a book or a way to start. I am looking for a book similar to Programming a Multiplayer FPS in DirectX but the problem with this book is the final code is directly given and executed. I am looking for a book which shows step by step building of an engine and then a game over it.

  10. Game Engine

    Thanks a lot for each one of your responses and i have decided first to make a game of my own then a engine.
  11. Game Engine

    Thanks for the response but i have worked on two projects in my university course work where in i made games using directx 11 and directx 9 using our professor's game engine. Also, i have an idea how each module of a game engine works too but i don't know know how to start making it from the scratch.(or is it still to early for me to consider making a game engine)
  12. Game Engine

    I am planning to build a game engine from scratch using c++ with directx 9. can some one tell me how to go about and also let me know if their is a book that shows step wise to make a game engine. Remember i m just a beginner and i have made games using some game engine and nothing more than that.
