50 Days of Becoming a Pro Game Programmer in C++ using SDL2

Initialize SDL with SDL_Init and the video subsystem to enable window creation, rendering, and graphical events. Write SDL commands between init and quit, then call SDL_Quit to release resources.

Create a GUI window using the built-in STL window class, pass a title, center the window, set width and height to 640 and 480, and show it immediately with SDL_WINDOW_SHOWN.

Learn how to delay an SDL window's display using the delay command, specifying milliseconds to show the window for set durations, from 3 seconds up to 80 seconds, before quitting.

Learn to check window creation and sdl initialization, print console errors when the window fails to create, and safely quit sdl when initialization or creation fails.

Learn to use SDL_DestroyWindow to destroy windows created with SDL_CreateWindow, freeing resources and preventing memory leaks, improving performance and responsiveness in SDL2 programs.

Define and experiment with SDL2 window properties, including position, size, visibility, fullscreen, borderless modes, and input focus to control window behavior in games.

Learn to set up an SDL renderer for a window, enabling hardware-accelerated rendering of shapes, textures, images, and colors, and manage renderer creation with window association and driver selection.

Learn to change the window background using SDL_SetRenderDrawColor with the renderer and an RGB color, such as red (255, 0, 0), and understand opacity values.

Set the STL window background to blue and draw a red point at 100,100. Use a for loop to draw points and present the render to form a visible line.

learn to draw lines and rectangles using an SDL renderer, specifying start and end coordinates or a rectangle’s position, width, and height, and experiment with color and multiple shapes.

Learn how SDL textures load images into GPU memory for fast real-time rendering, enabling scaling, rotating, blending, and sprite animations.

Destroy textures to free resources after closing the SDL application, and clean up by destroying the texture, renderer, and window, then quit the image library to improve efficiency.

Learn how to load and display BMP images in SDL without extra libraries by using SDL's built-in BMP support, creating surfaces and textures, and rendering win.bmp.

Learn how to handle the SDL window close event with an event loop and a quit flag to close only when the user presses the close button.

Set a window background in SDL2 by loading an image as a background texture and stretching to 800 by 600. Render the background first, then the ball and bat textures.

Learn to place and move items on an SDL window using x and y coordinates, with origin at the top-left, adjusting x for horizontal movement and y for vertical movement.

Learn how the SDL game loop uses a while not quit loop to update positions, clear each frame, and render the new frame, with an event handler for quitting.

Learn to move a rectangle in an SDL2 window using a game loop, starting from an initial position with speed and distance, updating x and y coordinates.

Move a ball image in all directions with sdl2 by initializing position and speed, cycling through up, right, down, left via an enum and switch, and rendering each frame.
