This video tutorial by Code Monkey teaches how to create a basic NPC interaction system in Unity. It covers setting up a demo, creating scripts for detecting and interacting with NPCs, and enhancing the system with UI elements. The tutorial also explains handling multiple interactions and using interfaces for a flexible system. The concepts are applicable to both 3D and 2D games.

What is the primary goal of the NPC interaction system introduced in the video?

• To design a multiplayer game environment

• To develop a new game engine

• To create a complex AI for NPCs

• To enable players to interact with NPCs and other objects

Which method is used to detect nearby NPCs in the basic interaction system?

• Physics.Raycast

• Transform.LookAt

• Vector3.Distance

• Physics.OverlapSphere

What is added to the interaction system to provide visual feedback to the player?

• Sound effects

• Chat bubbles and animations

• Multiplayer support

• Advanced AI behavior

Which Unity package is mentioned for adding dynamic logic to animations?

• Cinemachine

• Animation Rigging

• ProBuilder

• Shader Graph

How does the system ensure it interacts with the closest object when multiple are in range?

• By using a priority queue

• By checking the order in the physics world

• By using a random selection

• By calculating and comparing distances

What is the purpose of the 'get interact text' function in the interaction system?

• To trigger an animation

• To log the interaction to the console

• To return a string describing the interaction

• To display the NPC's name

What programming concept is introduced to make the interaction system more scalable?

• Abstract classes

• Interfaces

• Inheritance

• Delegates

What is the benefit of using interfaces in the interaction system?

• It improves the game's graphics

• It makes the system more flexible and reusable

• It allows for more complex animations

• It reduces the number of scripts needed

What is the main challenge addressed by refactoring the interaction system?

• Reducing code complexity and coupling

• Improving game performance

• Enhancing visual effects

• Adding more NPCs

What is the key difference when implementing the system in 2D instead of 3D?

• Altering the game's storyline

• Using different programming languages

• Changing the game engine

• Using different physics functions
