Redstone Components

This page will help you learn about the different types of components that can make up a redstone circuit. Only types of components that can be created with add-ons are documented.

Redstone Insulators ​

While they technically do not form part of a circuit, redstone insulators are very useful when building compact redstone circuits as they do not conduct a redstone signal when powered.

In the diagram below, the powered repeater on the left is strongly powering the stonecutter block. However, given that the stonecutter is a redstone insulator, the repeater to the right of it is not connected to the circuit so remains unpowered.

Creating Redstone Insulators ​

Creating custom redstone insulators couldn't be easier, since that's how custom blocks behave by default!

You don't need to add anything to your block's JSON definition.

Preventing Wire Step-Down ​

By default, wires of redstone dust are allowed to step down the side of insulators to carry power downwards. However, unlike other insulators such as glass, vanilla slabs do not allow wire to step down the side of them.

You can prevent wire from stepping down your own block by using the redstone conductivity component.

"minecraft:redstone_conductivity": {
    "allows_wire_to_step_down": false
}

Redstone Conductors ​

Redstone conductors are the opposite of insulators, they do conduct a redstone signal to adjacent blocks when powered.

• Strongly powering a conductor (using a redstone producer) will connect adjacent redstone dust and components to the circuit, causing them to receive the power that was conducted.

• Weakly powering a conductor (by powering redstone dust that is on top of or pointing into the conductor) will connect adjacent redstone components to the circuit, causing them to receive the power that was conducted without connecting adjacent redstone dust.

If a block is a redstone conductor, it will prevent wire from stepping down to the block directly below it, cutting the wire off from that part of the circuit.

In the diagram below, the powered repeater on the left is strongly powering the concrete block. Given that concrete is a redstone conductor, the repeater to the right of it is connected to the circuit so also becomes powered.

Creating Redstone Conductors ​

To create custom redstone conductors, you'll need to include the redstone conductivity component in your block.

"minecraft:redstone_conductivity": {
    "redstone_conductor": true
}

Redstone Producers ​

A block that supplies redstone power to a circuit is known as a redstone producer. Other redstone components can connect to producers to receive their power in the directions that the producer allows.

Excluding redstone blocks, all producers also strongly power one direction. This strong power can be conducted by redstone conductors to add more components to the circuit.

In the diagram below, the redstone torch is acting as the redstone producer of the circuit and can be connected to from all directions except down. Additionally, it is strongly powering the block above it.

Creating Redstone Producers ​

To create custom redstone producers, you'll need to include the redstone producer component in your block.

Here's how the redstone producer component of the lit redstone torch in the above diagram would look:

"minecraft:redstone_producer": {
    "power": 15,
    "strongly_powered_face": "up",
    "connected_faces": ["up", "north", "south", "west", "east"]
}
