I'm developing a 2D game in Java using Java Swing, and I've run into an issue with my player character's attack animation. The player has both movement and attack animations:
Movement sprites: 16x16 pixels Attack sprites: 80x80 pixels The movement animations work perfectly, and the player displays at the correct size. However, when I trigger the attack animation, the player sprite becomes very small, even though the attack sprites are larger than the movement sprites. The player goes through the complete axe attack animation however he becomes extremely small during the animation. Any insight would be greatly appreciated thanks !
Here's the relevant code from my Player class: package entity;
