Unoriginal yet very useful ; This is a FABRIC mod, which adds simple conveyors for transporting items and entities. Requires the Fabric API.

Features : Conveyors :

• Face in the direction that the player faces when they are being placed
• Convey entities or items along the direction they face
• If an entity collides with the side of a conveyor block, and the conveyor belt is facing up on that side, then the entity or item will be pulled up
• Can be powered to increase speed, as conveyors are slow when unpowered
• The speed scales with the redstone level being received
