Goomba AI | Coding a 2D Game Engine in Java #52

Join the Discord: https://discord.gg/4tHeAkxNg7

In this episode we implement a Goomba AI. This involves adding an enemy that paces back and forth and will kill Mario, or damage Mario, whenever he runs into Mario. So, we also have to implement a death animation for Mario where he jumps up and falls off the screen, and we have to implement a damage animation for Mario. We make use of several different features of this game engine to get the Goomba AI working pretty quickly. Finally we switch back to the base scene if the character dies, which reloads the level from the beginning.
