This datapack gives hoppers magnetic linking behavior for simplified item transportation systems.
Features
- Hoppers automatically link when placed in straight horizontal lines within 3 blocks of each other
- Links form regardless of hopper facing direction
- Items route toward the nearest valid inventory destination at chain ends
- Items move at twice normal hopper speed through chains
- Chain detection runs every few seconds and marks linked hoppers with particle pulses
- Breaking hoppers causes automatic rerouting through remaining connections
- Chains can branch at intersections with items splitting evenly between paths
- Lightweight detection system uses periodic position checking instead of per-tick scanning
- Uses area effect clouds as invisible markers to track links without constant block scanning
