Project Code Structure

Systems

CharacterMovementSystem: Process Character Movement

RandomPathfindingSystem: Handles Checking remaining destination distance & Set a new random position

RandomMovingCharacterSpawnerSystem: Only active once, Spawn the Character at startup & assign random destination

CharacterPathfindingMovement: Manage Character Movement velocity based on destination direction

Components

Singleton Components

GlobalCharacterMovementSpeed: Speed for all character

GlobalRandom: Global Unity.Mathematics.Random

RandomMovingCharacterSpawningProperty: Centralized data for character pathfinding config (only for spawning)

RandomPathfindingProperty: Centralized data for character pathfinding config (runtime)

Basic Components

Movement: Store Velocity

PathfindingDestination: Store Destination position
