Fade Effect using SDL2 and the Odin Programming Language

This is a simple tactic for creating a full-window fade effect using SDL2 - Simple DirectMedia Layer 2.

Creating a fade effect is easy using a single SDL Rect that covers the entire window. You can alter the alpha value when calling SDL's SetRenderDrawColor() function before calling RenderFillRect(). Using animation keyframes, you can gradually increase and decrease the alpha value to get the desired fade.
