Controlled Storage

A unified storage control mod that combines and enhances multiple storage-related features.

⚠ No Sweep Zones is currently not compatible with Better Dupe Assignment — BDA makes the No Sweep Zone apply to Sweepers too when it is supposed to apply only to Dupes.

• Empty Storage – Add "Empty Storage" button to storage buildings. Creates a dupe errand to drop all stored items. Optional skill requirement and instant emptying option.
• Controlled Filtering – Customize which item categories appear in storage filters (Clothing, Eggs, Sublimating items). Choose whether items are "standard" or "non-standard".
• Capacity Control – Increase character limit in capacity input fields. Support for larger storage values (up to 9,999,999 kg).
• Delivery Control – Control dupe and auto-sweeper deposit and extract permissions per storage building. Copy checkbox settings to other buildings of the same type via the Copy Delivery Settings button.
• No-Sweep Zones – Mark areas where Duplicants will not sweep items from. Toolbar icon and overlay to define zones.

1. Select a storage building (Storage Bin, Smart Storage Bin, Fridge, etc.)
2. Click "Empty Storage" in the building’s side panel
3. A dupe will be assigned to drop all stored items (or instantly if configured)

1. Select a storage or loader building with Delivery Control enabled
2. Toggle permissions for dupe deposit, dupe extract, sweeper deposit, and sweeper extract
3. Copy settings to other buildings of the same type using the Copy Delivery Settings button

1. Open the toolbar and select the No-Sweep Zone tool
2. Paint zones on the map where dupes should not sweep from
3. Use the overlay to visualize active zones

• Use Delivery Control to prevent sweeper loops by disabling sweeper extract on bins that sweepers deposit into
• No-Sweep Zones are great for keeping natural resources in place (e.g. Oxylite near your oxygen supply)
• Capacity Control lets you type values beyond 999,999 kg for modded high-capacity storage

Configure via Options > Mods > Controlled Storage:

• Immediate Emptying – Drop contents instantly or create a dupe errand (default: instant)
• Require Skills – Dupes need Tidy skill to empty solid storage (when not immediate)
• Use Work Time – Emptying takes time based on mass stored (when not immediate)
• Work Time per 100kg – Configurable from 0.1 to 10 seconds

• Clothing is Non-Standard – Move Clothing to Non-Standard filter section
• Critter Eggs are Non-Standard – Move Eggs to Non-Standard filter section
• Sublimating Items are Non-Standard – Move Bleach Stone, Oxylite, etc. to Non-Standard section

• Additional Input Characters – Extra characters beyond vanilla’s 6-character limit (default: 2, giving 8 total)

• Enable for Storage Bins – Add delivery control to Storage Bins and Smart Storage Bins
• Enable for Fridges – Add delivery control to Refrigerators and Ration Boxes
• Enable for Loaders – Add delivery control to conveyor loaders (Solid Conduit Inbox)

• Enable No-Sweep Zones – Adds the No-Sweep Zone tool to the toolbar

• Oxygen Not Included – Build 700386 or later
• Mod API – Version 2
• DLC Support – Works with base game and all DLC (including Bionic Booster Pack)
• Other Mods – Compatible with most mods

Minimal Performance Impact

• Event-Driven – No polling or continuous monitoring; patches only fire on relevant game events
• Lightweight Overlays – No-Sweep Zone overlay uses standard game overlay system

• Additional building type support for Delivery Control
• Enhanced No-Sweep Zone visualization options
