GH D3D9 Test Environment

This repository contains a simple Direct3D 9 test environment that can be used as a playground for experimenting with Direct3D 9 features, testing hacks, and learning about the inner workings of Direct3D 9.

Features

The D3D9 Test Environment provides a basic setup for a Direct3D 9 application, including:

  • A native window setup using the Win32 API.
  • Initialization of a Direct3D 9 device.
  • A simple render loop that clears the screen and presents the back buffer.

Code Overview

The codebase is divided into two main parts: WinMain.cpp and NativeWindow.cpp.

WinMain.cpp

This is the entry point of the application. It sets up a native window, initializes Direct3D 9, and enters the main application loop. The loop handles window messages and calls the Render function each frame.

The InitD3D function is responsible for initializing Direct3D 9. It creates a Direct3D 9 device and a font for drawing text. It also creates a sprite, which can be used for drawing 2D images.

The Render function is called each frame. It begins a new scene, clears the screen, draws some text using the previously created font and sprite, ends the scene, and presents the back buffer.

NativeWindow.cpp

This file contains the NativeWindow class, which encapsulates the creation and handling of a native window using the Win32 API. The Create function registers a window class and creates a window. The Register function registers a window class with the necessary attributes. The WndProc function is the window procedure that handles window messages.

FAQ

What is Direct3D 9?

Direct3D 9 is a version of Microsoft's Direct3D API, which is used for rendering 3D graphics in applications. It's part of the DirectX suite of multimedia APIs.

What is a native window?

A native window is a window that is created using the operating system's native windowing system. In this case, the native windowing system is the Win32 API, which is used to create windows on Windows.

What is a Direct3D 9 device?

A Direct3D 9 device is an object that represents a display adapter. It's used to create resources (like textures and vertex buffers) and render graphics.

What is a render loop?

A render loop is the main loop of a graphics application. It's responsible for rendering graphics each frame.

Prerequisites

To use this code, you should have a good understanding of C++ and the Win32 API. You should also be familiar with the basics of Direct3D 9.

End Goal

The end goal of this source code is to provide a simple Direct3D 9 test environment that can be used as a starting point for experimenting with Direct3D 9, testing hacks, and learning about the inner workings of Direct3D 9.

The D3D9 project makes use of the DXSDK_DIR macro, so if you don't have that set up you may run into errors. One quick little work around is to just add a new entry to your PATH variable with the name DXSDK_DIR and the value being the path (including trailing '') to the sdk on disk.

Getting Started

To get started with the D3D9 Test Environment, you'll need to clone the repository and open the solution file (TestEnvironmentD3D9.sln) in Visual Studio. From there, you can build and run the project.

Code Highlights

Here are a few key pieces of code that you might find interesting:

  • WinMain.cpp:

    • InitD3D: This function initializes Direct3D 9. It creates a Direct3D 9 device and a font for drawing text. It also creates a sprite, which can be used for drawing 2D images.
    • Render: This function is called each frame. It begins a new scene, clears the screen, draws some text using the previously created font and sprite, ends the scene, and presents the back buffer.
  • NativeWindow.cpp:

    • Create: This function registers a window class and creates a window.
    • Register: This function registers a window class with the necessary attributes.
    • WndProc: This function is the window procedure that handles window messages.

The D3D9 Test Environment is a great starting point for anyone interested in learning about Direct3D 9 or experimenting with game hacks. It provides a simple setup for a Direct3D 9 application, allowing you to focus on the fun stuff.
