Mechanic Upper

Transport behavior

Pulls from below and outputs upward or toward its horizontal facing direction.

Filter

A Filter Upgrade enables a whitelist or blacklist by item type. The filter applies to collection and output.

Estimated speed

One cycle every 8 ticks (about 2.5 cycles/s). Each collection/output pass attempts 1–5 stacks with 0–4 Speed Upgrades: about 2.5–12.5 stack attempts/s per pass.

Routing

Uses its physical output direction. Nearest, Farthest and Round Robin are network exporter modes, not hopper modes.

Collection sources

Reads the adjacent inventory, or chest/hopper minecarts when enabled; also collects dropped items when no source inventory is present.

• Nominal estimates assume 20 game ticks/s. Stack size, filters, available items, free space, sided I/O and loaded chunks can reduce actual throughput.
