Interactable Actors

Interactable Actors

The core of the S.B.I. system revolves around two key blueprint types:

• BP_MasterTarget

• BP_MasterControl

Both of these derive from a shared base class: BP_MasterInteractable.

---

🔹 BP_MasterTarget

Used for actors that receive inputs and perform actions. Examples: doors, lights, alarms, item pickups.

---

🔹 BP_MasterControl

Used for actors that send inputs to one or more targets. Examples: switches, levers, panels.

---

⚙️ Shared Base Class: BP_MasterInteractable

All interactable actors share a set of core variables for quick setup and customization, editable either in the Blueprint or per instance in the editor.

---

📁 Setting Default (BP_MasterInteractable)

Variable	Type	Description
Type	EN_InteractionType	Defines how the actor is interacted with:
• Press – Activates on button press
• Hold – Requires hold input (displays progress bar)
• Area – No direct interaction; triggered via overlap or external logic
HoldTime	Float	How long the button must be held (Hold type only)

---

🧾 Setting Widget

Variable	Type	Description
AllowWidget	Boolean	If true, shows interaction prompt when player looks at actor
PopUpText	Name	Text to display in the popup widget

---

🎒 Setting Requirement (Item-based Activation)

These variables apply if the interactable requires items to activate.

Variable	Type	Description
HasItemRequirement?	Boolean	If true, this actor requires items to activate
ItemToLookFor	EN_Item	Item type required
ItemQuantityToLookFor	Integer	Quantity of items required
AllItemsAtOnce	Boolean	If true, all required items must be delivered at once

---

🧩 BP_MasterControl Specific Variables

📁 Setting Default

Variable	Type	Description
Controls	Array	List of BP_MasterTarget actors to control
Active	Boolean	Is the control active by default
PairedControls	Array	Other controls linked to this one (e.g. disable others after use)
FiresOnce	Boolean	If true, can only be triggered once

---

⏱️ Delay Activation

Variable	Type	Description
HasDelay	Boolean	Enables delay before triggering target
Delay	Float	Delay time in seconds
AllTargetsWithDelay	Boolean	If true, applies delay to each controlled actor individually

---

🎯 BP_MasterTarget Specific Variables

Variable	Type	Description
FreeFromControls	Boolean	Can be activated directly by player (no control required)
Active	Boolean	Is it active by default
FiresOnce	Boolean	Can it be activated more than once

---

🔁 Blueprint Events & Flow

• Event Main Interaction Core event called when the actor is triggered. This is where you implement the logic for what should happen (open door, toggle light, etc.)

• Trigger Control (BP_MasterControl only) Call this to execute all linked BP_MasterTarget events.

⚙️ Note: Individual actor logic like lever movement or door animations are handled inside each actor’s custom Blueprint logic.
