This program demonstrates the basics of using SDL2 to create a graphical application in a Windows environment. It creates a resizable window and a renderer, and uses these to display and move a colored sqaure across the screen. The squares's movement is governed by its velocity and it bounces off the edges of the window. The color of the square changes if the user presses a key or clicks the mouse.
Instructions on how to run the project can be found down below.
- Window creation and management using SDL2.
- Real-time rendering of graphical elements with SDL2, including handling window resize events.
- Collision detection with window boundaries and response (bouncing effect).
- Interaction handling of keyboard and mouse input by way of event polling.
- Use of standard algorithms (std::clamp) to manage the rectangle's position within the window boundaries.
- The generation of random integers within a specified range. (See util.cpp)
- SDL2: A cross-platform library designed to provide low-level access to audio, keyboard, mouse, joystick, and graphics hardware. It is used to handle window creation, rendering graphics, and capturing input events.
- Vcpkg: A C++ dependency manager that simplifies the process of acquiring and building 3rd party libraries. Used here to install and link SDL2.
- Visual Studio 2022 Community Edition: Free C++ development environment with a compiler and build system that support libraries installed using Vcpkg.
- Clone the repository that contains this project.
