Using a Deployer to Automate Item Interactions

The Deployer is a versatile and indispensable block within the Create mod for Minecraft, designed to automate a wide array of item interactions that typically require direct player input. By mimicking player actions such as right-clicking or left-clicking, Deployers enable complex automation setups, from farming and crafting to construction and combat. Understanding its core mechanics and proper configuration is key to unlocking its full potential in your automated factories and contraptions.

Key Mechanics of the Deployer

Deployers are engineered to replicate player interactions within the game world. They possess several distinct characteristics that govern their operation:

• Imitation of Player Actions: A Deployer can be configured to perform either a “Use” action, which simulates a player’s right-click, or an “Attack” action, which simulates a player’s left-click. This fundamental capability allows it to interact with blocks, entities, and items in diverse ways, such as opening doors, activating levers, or breaking blocks.
• Activation Space: The Deployer performs its designated action in the block space located two meters directly in front of it. Notably, it has the unique ability to pass through any intermediate blocks between itself and the target interaction space, meaning it doesn’t require a clear line of sight in terms of physical blocks, only the target space itself.
• Rotational Force Requirement: For a Deployer to operate, it must be supplied with a constant source of rotational force, measured in Kinetic Stress Units (SU). The speed at which the Deployer activates is directly correlated with the input Revolutions Per Minute (RPM) it receives. Higher RPM generally results in faster, more frequent actions.
• Item Provision: Items that the Deployer is intended to “use” or “hold” can be supplied in multiple ways. They can be inserted directly into the Deployer’s inventory, placed by right-clicking the item onto the Deployer block itself, or automatically fed from an attached portable storage unit. This flexibility allows for various item supply chain designs.
• Internal Inventory: Each Deployer features a small internal inventory system consisting of two slots. One slot is specifically designated for the item it is currently holding and prepared to use for interaction. The second, an extra internal slot, is reserved for items that are obtained as a result of an interaction, such as milk from a cow or drops from a broken block.
• Handling Obtained Items: When a Deployer successfully obtains items through an interaction, their destination depends on the surrounding setup. If a portable storage unit (like a chest or barrel) is attached to the Deployer, these obtained items will be automatically transferred into that storage. If no portable storage is present, the items will be dropped into the world. However, if the Deployer is stationary and lacks attached portable storage, any items it obtains will instead be placed into its extra internal inventory slot.
• Redstone Control: Deployers can be temporarily halted using a Redstone signal. When a Redstone signal is applied, the Deployer will cease its actions. It’s important to note, however, that even when stopped by Redstone, the Deployer will continue to consume Kinetic Stress Units (SU) as long as it is receiving rotational power.

Step-by-Step Process for Using a Deployer

To effectively integrate a Deployer into your automated systems, follow these steps:

1. Craft a Deployer: The first step is to craft the Deployer itself. This requires combining specific Create mod components: a Brass Casing, two Cogwheels, one Electron Tube, and a Hand.
2. Place and Power: Carefully position the Deployer in your world, ensuring it is facing the exact block space or entity where you intend for it to interact. Once placed, connect it to a reliable source of rotational power. This can be achieved using various Create components such as shafts, gearboxes, or encased gears, transmitting Kinetic Stress Units (SU) to the Deployer.
3. Provide Items: Supply the Deployer with the item(s) it needs to perform its actions. You can do this by right-clicking the item directly onto the Deployer block, inserting items into its inventory through an automation system, or by using funnels or chutes to pull items from an adjacent inventory into the Deployer.
4. Set Mode: Determine whether the Deployer needs to simulate a right-click or a left-click. Use a Wrench tool on the front face of the Deployer to toggle between its “Use” mode (for right-click actions like placing blocks or using tools) and its “Attack” mode (for left-click actions like breaking blocks or attacking entities).
5. Configure Filters (Optional but Recommended): To ensure precise operation and prevent issues, it is highly recommended to configure a filter. Place a filter item into the Deployer’s dedicated filter slot. This filter dictates which specific items the Deployer should use, or which items it should pull from an attached portable storage unit. Filters are crucial for preventing the Deployer from using unintended items or becoming clogged.
6. Automate Item Flow: For continuous and efficient operation, establish a system for both supplying items to the Deployer and extracting items it collects. Utilize Create’s item transport mechanisms such as funnels, chutes, or mechanical belts to automatically feed the necessary items into the Deployer and to retrieve any processed or collected items from it.

Important Tips for Deployer Usage

Leveraging Deployers efficiently often involves understanding their unique capabilities and control methods:

• Exceptional Versatility: Deployers are incredibly versatile. They can perform a wide range of actions including, but not limited to, opening and closing doors, pushing buttons, placing new blocks, breaking existing blocks, attacking hostile or passive entities, milking cows with buckets, shearing sheep with shears, and even crafting components directly on mechanical belts when supplied with the necessary ingredients. Their ability to replicate player actions makes them central to many advanced automation designs.
• Portability on Contraptions: Deployers are not limited to stationary setups. They can be mounted onto moving contraptions, allowing for mobile automation. When a Deployer is part of a contraption, it will activate once for every new block position the contraption moves to, enabling dynamic interactions across an area.
• Single Action Control: For situations requiring a Deployer to perform only a single, precise action rather than continuous operation, a specific Redstone circuit can be employed. Power the Deployer with rotational force and apply a constant Redstone signal to keep it stopped. Temporarily removing this Redstone signal for a brief moment will trigger the Deployer to perform exactly one action before it stops again if the Redstone signal is reapplied.
• Vertical Deployers: When a Deployer is placed vertically and set to “Use” mode, it will aesthetically display the item it is holding within its mechanism. Despite this visual change, its functionality remains consistent; it will still activate normally with rotational power, interacting with the block space two meters in front of its interaction face.
• Schematic Printing: A Deployer integrated into a contraption can be used for schematic printing. If supplied with building materials and equipped with a Schematic filter, it can place blocks according to a loaded schematic. This function only places blocks where the target space is clear, making it ideal for automated construction.

Common Mistakes to Avoid

To ensure your Deployer setups run smoothly, be aware of these common pitfalls:

• Incorrect Mode Selection: A frequent error is setting the Deployer to the wrong mode. Always double-check that it’s in “Use” mode for right-click actions (like placing blocks, interacting with containers, or using tools) and “Attack” mode for left-click actions (such as breaking blocks with a tool or damaging entities). An incorrect mode will lead to unexpected or failed interactions.
• Insufficient Power: Deployers require a constant supply of Kinetic Stress Units (SU) to function. If the Deployer is not receiving enough rotational force, it will either operate very slowly or fail to activate entirely, bringing your automation to a halt. Ensure your power network can adequately supply all connected Deployers.
• Improper Item Handling: Without a proper system for managing items, Deployers can become clogged. This happens if there’s no mechanism to extract items collected by the Deployer, or if filters aren’t set up correctly, allowing unwanted items to enter. Such issues can cause the Deployer to stall, preventing further operation until the blockage is cleared.
• Claimed Chunks/Mod Conflicts: In certain modpacks or server environments, Deployers may not function as expected within claimed chunks due to permission settings. Additionally, conflicts with other installed mods (e.g., those affecting entity interaction or block placement, like Minecolonies permissions) can sometimes prevent Deployers from operating correctly. Always check server rules or mod compatibility if encountering unexplained issues.
• Incorrect Placement: Proper placement is crucial. Remember that the Deployer activates two blocks away from its face. Ensuring it is precisely positioned relative to its target is vital. For Deployers mounted on contraptions, placing them facing forward often yields more reliable and predictable results during movement.
• Lack of Filters: Neglecting to use filters can lead to significant problems. Without a filter, a Deployer might attempt to use unintended items from its inventory or become clogged with unwanted items collected from interactions. Filters are essential for maintaining precise control over item input and output, preventing operational disruptions.
