When you build an animated sprite in PixiJS, you use a sequence of textures that represent each animation frame. The PIXI.AnimatedSprite class allows you to easily create and control these frame-based animations. You can adjust the animation's speed by setting the animationSpeed property; a higher value means the frames advance faster, while a lower value slows the animation down. By default, the animation will loop—meaning it restarts automatically after reaching the last frame. You can control this behavior using the loop property. Setting loop to false makes the animation play just once and then stop on the final frame. To start the animation, call the play() method. You can also pause or stop the animation as needed to control playback in your game logic.
