Modern Gaming

Game Engine

A software framework (like Unity or Unreal Engine) providing rendering, physics, sound, and scripting tools.

Indie Game

A video game created by individuals or small independent teams without direct funding from large publishers.

Digital Distribution

Delivering video games digitally over the internet without physical discs or retail packaging.

Cross-Play

The ability for players on different gaming hardware (e.g., PC, Xbox, PlayStation, Switch) to play together in the same match.

Explore the major subsystems running inside a modern game engine like Unreal or Unity.

1. 1Rendering Pipeline: Computes real-time lighting, shaders, shadows, and post-processing visual effects.
2. 2Physics Engine: Simulates rigid body collisions, cloth simulation, raycasts, and gravity dynamics.
3. 3Audio Subsystem: Positions 3D spatial audio, dynamic music transitions, and sound effect filters in real time.
4. 4Scripting & Logic: Executes gameplay rules, quest progress, and NPC artificial intelligence state machines.

pythonclass NPC:
    def __init__(self, name):
        self.name = name
        self.state = 'PATROL'

    def update(self, player_distance):
        if player_distance < 5:
            self.state = 'CHASE'
        else:
            self.state = 'PATROL'
        print(f'{self.name} state: {self.state}')

guard = NPC('Castle Guard')
guard.update(12)
guard.update(3)

Modern game AI uses state machines and behaviour trees to decide when characters patrol, alert, or attack based on player actions.
