Difficulty Scaling Overview

Overview

Game object balancing is configured through configuration files. Each entity type has its own configuration asset, where you can define behavior parameters such as damage, health, movement speed, and other characteristics.

Configs path: Assets/StaticAssets/Configs/...

Object	Config	Purpose
Stickman	EnemyConfig	Health, reward
Tentacle	TentacleConfig	Health
Player	PlayerConfig	Health, movement speed
Rocket	RocketConfig	Damage
Turret	TurretConfig	Attack interval, ammo count
Projectile	ProjectileConfig	Damage

Notes (Optional, but recommended)

• All configs are implemented as ScriptableObject assets.

• Difficulty scaling can be achieved by adjusting these configuration values without modifying code.

• Configs can be reused across multiple levels or game modes.

Balance Parameter Calculation

The calculation of balance parameters in the game is handled by three core classes: PlayerStats, TentacleStats, and EnemyStats. Each class reads values from configuration assets (ScriptableObjects) and computes runtime stats, including health, damage, speed, and other characteristics.

---

PlayerStats

Handles the player’s runtime stats such as health, movement speed, projectile damage, rocket damage, and ammo count. It uses configuration files and the player’s upgrade levels to calculate values dynamically.

Key Features:

• Reads values from PlayerConfig, ProjectileConfig, TurretConfig, and RocketConfig.

• Calculates:

  • Current health (CurrentHealth)

  • Movement speed (CurrentSpeed)

  • Turret damage (CurrentDamage)

  • Rocket damage (RocketDamage)

  • Ammo count (CurrentBullets) and low-bullets threshold

  • Fire interval (FireInterval)

• Supports upgrade level scaling via IPlayerContext.

public void Initialize()
{
    CalculateAmmoAmount();
    CalculateFireInterval();
    CalculateProjectileDamage();
    CalculateHealth();
    CalculateSpeed();
    CalculateRocketDamage();
}

---

TentacleStats

Manages health and damage for Tentacle-type enemies.

Key Features:

• Reads values from TentacleConfig.

• Calculates:

  • Current health (CurrentHealth)

  • Damage based on health ratio (CurrentDamage)

• Supports level-based scaling.

int GetEnemyHealth(int level)
{
    return Mathf.RoundToInt(config.baseHealth + (level - 1) * config.healthGrowthPerLevel);
}

---

EnemyStats

Manages health and damage for general enemies.

Key Features:

• Reads values from EnemyConfig.

• Calculates:

  • Current health (CurrentHealth)

  • Damage scaled by health ratio (CurrentDamage)

• Supports level-based scaling.

int GetEnemyHealth(int level)
{
    return Mathf.RoundToInt(enemyConfig.baseHealth + (level - 1) * enemyConfig.healthGrowthPerLevel);
}

Adding New Statistics

You can extend or modify existing statistics to customize gameplay.

Custom Formulas: Replace the default calculation formulas in PlayerStats, TentacleStats, or EnemyStats with your own formulas to adjust values such as health, damage, speed, or fire rate.

Gameplay Tuning: Changing formulas allows you to tweak difficulty, pacing, and the overall game feel without modifying core game logic.
