How Build Mode blocks fit together

Build Mode starts in a private server through Free Build or the M shortcut. A useful setup usually has three parts: something the player touches or presses, something that carries or changes the signal, and something that happens after the signal arrives. A Touch block connected to a Teleport Block makes a basic portal. A Prompt connected through a Timer Block can delay a Sound Block, Mover Block, or Damage Block. A Connect block can let a custom Skill Builder move trigger map logic when that ability reaches the matching Connect node.

Build need	Blocks or tools to start with	What to check first
Simple structure	Part, Wedge, Trusses, Image, Texture	Collision, material, transparency, and breakability
Player trigger	Touch, Prompt, Connect	Matching ID, range, hold time, and player position
Visible result	Sound, Vehicle, Team, Mover, Dummy, NPC	Destination, one-spawn limit, team color, HP, or playstyle
Player effect	Damage, Moveset, Teleport, Speed, Character	Powered region size and whether the player is inside it
Signal control	AND, Light, NOT, Timer, XOR	Threshold, delay, Flip, and matching input/output IDs

What to test before a block looks broken

Most failed Build Mode setups come from placement or ID mistakes, not from the block itself. Interaction Blocks only apply their effect while they are powered and while the player's torso is inside the block. If a Touch block powers a Moveset, Erase, Teleport, Speed, or Damage zone, overlap the trigger and the effect region so the player is inside both at the same time.

IDs are the other easy mistake. Logic blocks only talk to blocks with the matching ID, and copied blocks can keep old IDs. Clone is helpful for repeating hazards or rooms, but cloned logic should be renamed when it is meant to run a separate circuit.

When gates and tools save time

Logic Gates are for builds that need timing or conditions. AND Gates help with multi-button doors. NOT Gates are useful for default-on or inverted behavior and can replace a pile of scaled input regions. Timer Blocks delay events, which is especially useful when Teleport and Moveset timing would otherwise fire in the wrong order. Light Blocks are useful as visible indicators and switch-style pieces because the Flip setting can make connected input behavior act like a toggle.

The editor tools keep the build manageable. Move Value and Rotate Value control precision. Position, Rotation, and Size do the actual placement work. Logic Wires help trace circuits before testing. Saves matter before any large change because loading a slot removes the placed build first, and Autosave is better as recovery than as the only save plan.

How to Use This Jujutsu Shenanigans Build Blocks List

Cards are grouped by the Build Mode menu role: structure, input, output, interaction, logic, or tool. Inputs tells what starts the row. Outputs tells what the row sends, creates, or changes. Trigger behavior explains whether it needs a matching signal, a player inside the region, or a manual editor action. Settings names the options that change the result, while Limitations calls out setup traps such as one-vehicle spawns, team color rounding, destination parts, save-slot behavior, and Interaction Block placement.

FAQ

How many Build Mode blocks and tools are in this Jujutsu Shenanigans list?

There are 47 rows: 35 powered or placeable blocks and 12 Build Tool rows. Position, Rotation, and Size are split into separate tool rows because builders choose them separately while editing.

Do you need a private server to use Build Blocks?

Yes. Build Mode is a private-server feature, and Free Build gives a selected player access to the build tools. Workshop can share or load creations, but Workshop tabs are not Build Block rows.

What is the difference between Input, Output, Interaction, and Logic Gate blocks?

Input Blocks start signals, Output Blocks perform actions after receiving signals, Interaction Blocks affect players inside powered regions, and Logic Gates change signal rules such as thresholds, delays, inverted behavior, and switch-style toggles.

Why are Skill Builder nodes not included here?

Skill Builder nodes are a separate custom-move system. Build Blocks such as Moveset, Special, Awakening, Character, and Connect can link into Skill Builder, but timeline nodes like Projectile, Grab, Counter, Tag, and State belong in the separate skill-builder collection.

Why are images hidden for Build Blocks?

Build Mode has broad menu screenshots, not clean row-specific images for all 47 rows. Hidden images are safer than repeating the same screenshot or using guide thumbnails that do not show the exact block.
