Frame-based animation is a core technique used in 2D games to bring graphics to life. In this approach, the visual state of the game is updated at regular intervals, known as frames. Each frame represents a single snapshot in time, and by displaying a sequence of these frames quickly, you create the illusion of movement. This technique is widely used because it enables you to control how and when objects change on the screen, such as moving a character or animating an explosion.

When you use frame-based animation, you update the position, appearance, or state of your sprites based on the current frame. By adjusting these properties a little bit each frame, you achieve smooth transitions and realistic motion. For example, moving a sprite 2 pixels to the right every frame will make it appear to glide smoothly across the screen. This level of control is essential for games, where timing and responsiveness are critical for gameplay.

Frame-based animation is also highly flexible. You can synchronize different elements, trigger effects at specific moments, and respond to user input in real time. This makes it possible to create complex scenes where many objects move and interact independently, all governed by the passage of frames. As you continue to develop your game, understanding how to harness frame-based animation will help you create more dynamic and engaging experiences for your players.
