Understanding the Character Block System

The Character Block is the foundation of custom character creation in Jujutsu Shenanigans. This powerful feature, introduced in recent updates, allows you to create entirely new playable characters that appear directly in the character selection menu with their own unique movesets and abilities.

What Makes Character Block Special?

Unlike traditional character customization, the Character Block system gives you complete control over every aspect of your fighter’s abilities. You’re not just recoloring existing characters – you’re building them from the ground up using the game’s extensive library of skills, animations, and effects.

Key Benefits:

Complete creative freedom over movesets
Custom character names and icons
Unique ability combinations
Personalized melee animations
Special awakening abilities

Prerequisites for Character Creation

Before diving into character creation, ensure you have:

Access to a Private Server (required for Build Mode)
Basic understanding of Jujutsu Shenanigans combat mechanics
At least 30-60 minutes of uninterrupted time for your first character
Creative vision for your character’s theme and playstyle

Step-by-Step Character Creation Process

Step 1: Accessing Build Mode

To begin creating your custom character, you’ll need to access Build Mode:

Enter a Private Server – Character creation is only available in private servers
Press “M” to toggle Build Mode on/off
Alternatively, use the “Free Build” command in the Players section of your private server settings

Pro Tip: While in Build Mode, you cannot use regular movesets or combat abilities. Enable the “No Stun” setting if you want to test your character while building.

Step 2: Placing Your Character Block

Open the Build Menu by pressing B while in Build Mode
Navigate to the Logic Blocks section
Select “Character Block” and place it in your workspace
Configure the Character Block by clicking on it

The Character Block serves as your character’s foundation and will appear in the character selection menu once configured.

Step 3: Setting Up Character Basics

When you first place your Character Block, you’ll need to configure the basic settings:

Character Name: Choose a unique name that represents your character’s theme Base Template: Select a UI layout and ability bar configuration Icon: Upload or select an image to represent your character in menus

Important: Your character name must be unique and appropriate. Avoid using special characters that might cause display issues.

Mastering the Skill Builder System

The Skill Builder is where your character truly comes to life. This powerful system allows you to combine existing game skills, animations, and effects to create entirely new abilities.

Understanding the Three Main Tabs

The Skill Builder interface consists of three essential tabs:

1. Timeline Tab: Where you structure your custom move’s sequence 2. Conditions Tab: Where you set usage limitations and requirements
3. Properties Tab: Where you fine-tune miscellaneous settings

Creating Custom Skills and Abilities

Designing Your Character’s Moveset

A well-designed moveset should reflect your character’s theme and playstyle. Here’s how to approach it:

1. Define Your Character’s Role

Agile Fighter: Focus on mobility and quick attacks
Heavy Hitter: Emphasize powerful but slow moves
Balanced Warrior: Mix of offense and defense
Specialist: Unique gimmick or mechanic

2. Plan Your Ability Structure

4 Regular Skills: Core combat abilities
1 Special Ability: Unique or enhanced move
1 Awakening: Ultimate ability
Custom M1s: Personalized melee attacks

Step-by-Step Skill Creation

Creating Regular Skills

Select the Skills section in your Character Block
Click “Add Skill” to create a new ability
Name your skill something descriptive
Set the cooldown (recommended: 5-20 seconds)
Open the Skill Builder by clicking “Edit”

Example: Creating a Fire Punch

Timeline Setup:

0.0s: Animation Block (Punch animation)

0.2s: Sound Block (Impact sound)

0.3s: Hitbox Block (Fire damage, 15 studs range)

0.5s: Wait Block (Recovery time)

Designing Special Abilities

Special abilities should define your character’s unique playstyle:

Key Considerations:

Higher cooldown than regular skills (20-40 seconds)
More impactful effects
Often mobility or burst damage focused
Should complement your regular skills

Popular Special Ability Types:

Mobility Skills: Dashes, teleports, flight
Burst Damage: Powerful single attacks
Combo Extenders: Skills that continue combos
Defensive Moves: Counters, barriers, heals

Creating Awakening Abilities

Awakenings serve as your character’s ultimate ability:

Essential Settings:

Duration: How long the awakened state lasts
Delay: Synchronization with activation animation
Effects: What happens during awakening

Awakening Design Tips:

Make it feel powerful and game-changing
Include visual and audio effects
Consider temporary stat boosts
Add unique mechanics not available in regular skills

Advanced Character Creation Techniques

Custom M1 (Melee) Creation

Custom melee attacks are what make your character truly unique. Here’s how to create them:

Understanding M1 Timing

Based on community research, the optimal timing for each M1 is approximately 0.45 seconds. This ensures smooth, responsive melee combos.

Creating Custom M1s

Access the Melee section in your Character Block
Create new M1 and M2 animations
Add Hitbox Blocks to ensure damage registration
Test timing to ensure smooth combos

Critical Warning: Without proper hitboxes, your melee animations will play but won’t deal damage. Always test your M1s in combat.

Advanced Skill Builder Techniques

Using the Connect Block

The Connect Block allows for complex interactions between abilities:

Signal System: Uses ID-based communication
Range Setting: Determines activation distance
Duration: How long the signal lasts

Branching Logic

Create conditional abilities using the Branch settings:

Input Requirements: Specific skill combinations
Timing Conditions: Precise activation windows
State Dependencies: Character status requirements

Visual Effects Mastery

The Visual Block can create stunning effects:

Particle Systems: Custom visual effects
Screen Effects: Camera shakes, filters
Environmental Changes: Temporary world modifications

Troubleshooting Common Issues

Character Not Appearing in Menu

Ensure Character Block is properly saved
