1 pointAre you sure you've got the correct typings for your pixijs version? In v5 animatedsprite is moved from extras to PIXI namespace, and those typings have only stub class. Well, if you dont understand how to fix typings or you cant wait for answer you should use JS. In that case i recommend to clone pixijs repo to your computer because docs can wrong you too. There's a rumor that certain parts of PixiJS will be moved to typescript this year *insert evil laugh here*.
