Overview

This mechanic, commonly known as job system / multi-class, defines how players interact with this aspect of the game world. The implementation varies significantly across genres, with each game adapting the core concept to fit its specific design goals and target audience. Modern implementations often combine this mechanic with procedural elements to increase variety and replayability.

Game Examples

Tactical Shooters

Tactical Shooters use this mechanic where players balance risk and reward to support their team effectively. The system supports both casual and hardcore engagement, resulting in build diversity.

Hack and Slash Games

Hack and Slash Games use this mechanic where players learn through failure to create unique character builds. The mechanic creates natural tension and release cycles, resulting in meaningful player agency.

Soulslike Games

Soulslike Games use this mechanic where players time their actions precisely to create unique character builds. Multiple valid strategies exist for different playstyles, resulting in a sense of mastery.

Pros & Cons

Advantages

Provides clear visual feedback on player actions

Encourages supportive playstyles and experimentation
Adds accessibility without excessive complexity
Creates satisfying immediate loops

Disadvantages

Difficult to balance across a wide range of skill levels
Requires significant server resources to implement well
Risk of power creep in competitive environments
May conflict with combat systems in the game

Implementation Patterns

Level-Up Handler

A modular approach to job system / multi-class that separates concerns and enables easy testing.

class JobSystemMultiClassSystem {
  rank = 1;
  points = 0;

  addXP(amount: number) {
    this.points += amount;
    while (this.points >= this.xpToNext()) {
      this.points -= this.xpToNext();
      this.rank++;
      this.onLevelUp();
    }
  }

  xpToNext() {
    return Math.floor(150 * Math.pow(1.1, this.rank - 1));
  }

  onLevelUp() {
    // Grant rewards for level rank
    this.mastery += 1;
  }
}

Weighted Skill Tree Controller

Data-driven implementation that loads job system / multi-class configuration from external definitions.

class JobSystemMultiClassSystem {
  level = 1;
  xp = 0;

  addXP(amount: number) {
    this.xp += amount;
    while (this.xp >= this.xpToNext()) {
      this.xp -= this.xpToNext();
      this.level++;
      this.onLevelUp();
    }
  }

  xpToNext() {
    return Math.floor(150 * Math.pow(1.1, this.level - 1));
  }

  onLevelUp() {
    // Grant rewards for level level
    this.mastery += 5;
  }
}
