Learning Objectives
By the end of this lab, you will be able to: - Create an enemy as its own reusable scene. - Implement simple autonomous behavior (patrolling between points). - Use Godot’s navigation system to move an enemy toward a target. - Handle enemy/player interaction using signals.
Overview
This lab introduces autonomous, rule-driven behavior. You’ll build an enemy that acts on its own — either patrolling a fixed route or navigating toward the player using Godot’s navigation tools. The broader lesson is how to write logic that reads the current state of the game and decides what to do next, which is the same kind of thinking behind any AI or rule system you’ll write later. You’ll also connect enemy and player so contact produces a consequence.
Steps
- Build an enemy scene (body + sprite + collision) so it can be instanced.
- Implement a simple patrol: move between two points, flipping direction at each end.
- Set up a NavigationRegion2D and use a NavigationAgent2D to path toward the player.
- Connect a signal so contact between enemy and player triggers a response.
- Instance several enemies to confirm each behaves independently.
Key Concepts
- Reusable enemy scenes and instancing (callback to Lab 1).
- State-driven behavior and simple decision logic.
- NavigationRegion2D and NavigationAgent2D.
- Signals for entity interaction.
Deliverable / Completion Check
A level with at least one autonomous enemy that either patrols or pathfinds toward the player, and a defined consequence when it reaches the player. Submit the running project or a screen recording.
