In addition to the parallax tutorial I published a few days ago, I just put out a new video on how to make melee combat in Godot. It's simple, quick, and scalable for larger games. I hope you find it helpful!
Additionally, I have two new series that will be coming out over the next month: a series on how to add transitions and animations to menus, and a series on making a text adventure game similar to old-school retro games like Zork. Make sure to subscribe to the channel and support!
