Tower Defense Mechanism

"I’ve been exploring older Fortnite Creative Tower Defense maps and learning about their construction, but I’ve noticed that many of the mechanisms used in those maps are outdated or no longer functional. Specifically, I’m facing challenges in setting up a system where enemies follow a predetermined path, implementing turrets or NPCs that can target and shoot these enemies, and establishing a health bar system to track and manage damage. I’m looking for up-to-date resources, such as links or videos, that can provide guidance on these aspects and help me get started with creating a more modern and effective Fortnite Creative Tower Defense map. Any recommendations or insights would be greatly appreciated!
