Xogot Game Development Tutorials (Godot on iPad & iPhone) - Introduction to Area3D in Xogot – Game Development in Godot on iPad

In this video, Erin introduces the Area3D node in Xogot and shows how to use it with signals to trigger gameplay events in a 3D project. You’ll learn how Area3D works like a sensor that detects when a physics body enters or exits a collision space, and how to connect those events to scripts using signals. The tutorial walks through a practical example by adding a fall sensor to a platform scene, printing debug output, and reloading the current scene when the player enters the area. This video is part of Xogot’s modular 3D game development series, designed to help you learn Godot’s 3D systems on iPad one concept at a time. Topics covered: * What Area3D is and when to use it * Common uses for Area3D, like triggers, portals, hit boxes, and goal zones * Adding an Area3D node as a fall sensor * Setting up a CollisionShape3D for the area * How signals let nodes communicate * The “call down, signal up” approach * Connecting the body_entered or body_exited signal to a script * Printing debug output when a body enters the area * Reloading the current scene when the signal fires Project Files: https://github.com/xogot-projects/Xogot-Area3D/archive/refs/heads/main.zip GitHub: https://github.com/xogot-projects/Xogot-Area3D Built entirely on iPad with Xogot If you haven’t seen them yet, check out the earlier videos in this series: WorldEnvironment: https://youtu.be/3qniuBdU_fE 3D Lighting: https://youtu.be/8eVlB9sRc3o Cameras: https://youtu.be/qfxw5d5jSko Placeholder Models: https://youtu.be/hc7MlyQYMdQ Placeholder Scenes: https://youtu.be/CfEWURgQuW0 Physics Bodies: https://youtu.be/zmtYP4tXzVU 3D Collision: https://youtu.be/rzo3yKURTOQ Area3D & Signals: https://youtu.be/GmH1RmXieZQ #Xogot #Godot #GodotEngine #Godot3D #GameDev #Area3D #Signals
