Attach Tool & Remove Tool

Overview

Use Attach Tool to equip a 3D tool object to the learner’s hand representation in the scene. This is essential for procedural training where learners need to handle specific tools — screwdrivers, wrenches, safety equipment, or specialized instruments. Use Remove Tool to detach the tool when it’s no longer needed. Attaching tools makes training more realistic and helps learners understand which tools are used at each step.

Attach Tool

When to Use

Equip at procedure start — Give learners a screwdriver before the assembly step
Tool-specific steps — Provide the right tool for each procedure phase
Safety equipment — Attach protective tools or equipment (fire extinguisher, first aid kit, etc.)
Context authenticity — Make training visually match the real-world procedure
Multiple tools — Attach different tools at different steps of a multi-phase procedure

Parameters

Parameter	Type	Required	Description
Tool Asset	Asset Reference or String	Yes	The 3D tool object to attach (e.g., `"screwdriver-phillips"`, `"wrench-10mm"`, `"fire-extinguisher"`)
Hand	String	No	Which hand to attach to: `"left"`, `"right"`, or `"both"` (default: `"right"`)

Example 1: Attach Screwdriver to Right Hand

Action: Attach Tool
Tool Asset: "screwdriver-phillips"
Hand: "right"

A Phillips screwdriver appears in the learner’s right hand.

Example 2: Attach Wrench to Left Hand

Action: Attach Tool
Tool Asset: "wrench-10mm"
Hand: "left"

A 10mm wrench appears in the learner’s left hand.

Example 3: Attach Tool to Both Hands

Action: Attach Tool
Tool Asset: "pliers-standard"
Hand: "both"

Pliers appear in both hands for two-handed handling.

Remove Tool

When to Use

Remove tool after the step requiring it is complete
Clean up tools before transitioning to the next phase
Prepare for a non-tool-based step or inspection phase

Parameters

Parameter	Type	Required	Description
Hand	String	Optional	Which hand to remove from: `"left"`, `"right"`, `"both"`, or omit to remove from both

Example 1: Remove Tool from Right Hand

Action: Remove Tool
Hand: "right"

The tool is removed from the learner’s right hand.

Example 2: Remove Tool from Both Hands

Action: Remove Tool
Hand: "both"

Tools are removed from both hands.

Example 3: Remove Tool (All Hands)

Action: Remove Tool

All attached tools are removed.

Best Practices

Attach before the step

Use Attach Tool in onEntry before the step requiring the tool.

Remove after the step

Use Remove Tool in onExit to clean up before transitioning.

Match hand dominance

For realistic training, attach tools to the dominant hand (right for most learners, unless specified).

Show tool attachment

Use Show Text or Show Panel to explain what tool is being provided.

Combine with hand representation

Use Set Hand Representation to show gloved or specialized hands holding the tool.

Test tool visibility

Verify the tool 3D model is visible and properly scaled on different screen sizes.

Common Patterns

Single-Tool Procedure

State: OpenThePanel
  onEntry:
    → Attach Tool (Tool Asset: "screwdriver-phillips", Hand: "right")
    → Show Panel
        Title: "Remove Panel Screws"
        Display Text: "Using the Phillips screwdriver in your right hand, remove all four panel screws."
        Billboard: true
    → Set Interactable Objects (["screw-1", "screw-2", "screw-3", "screw-4"], true)

  transitions:
    - event: "all-screws-removed"
      target: "PanelRemoved"

  onExit:
    → Hide Panel
    → Remove Tool (Hand: "right")

A screwdriver is provided, the learner removes screws, then the screwdriver is removed.

Multi-Tool Procedure

State: Step1-Disassemble
  onEntry:
    → Attach Tool (Tool Asset: "wrench-10mm", Hand: "right")
    → Show Text "Step 1: Use the wrench to loosen the bolts."
    → Set Interactable Objects (["bolt-1", "bolt-2", "bolt-3"], true)

  onExit:
    → Remove Tool (Hand: "right")

State: Step2-Replace
  onEntry:
    → Attach Tool (Tool Asset: "screwdriver-flat", Hand: "right")
    → Show Text "Step 2: Use the screwdriver to remove the cover plate."
    → Set Interactable Objects (["cover-plate"], true)

  onExit:
    → Remove Tool (Hand: "right")

State: Step3-Inspect
  onEntry:
    → Show Text "Step 3: Inspect the component with bare hands. No tools needed."
    → Set Interactable Objects (["component"], true)

  onExit:
    → Hide Text

Different tools are attached and removed as the procedure progresses.

Two-Handed Tool Use

State: AssembleWithPliers
  onEntry:
    → Attach Tool (Tool Asset: "pliers-slip-joint", Hand: "both")
    → Show Panel
        Title: "Secure the Connection"
        Display Text: "Using both pliers, firmly grip and twist the connector into place."
        Media: "pliers-technique.png"
        Billboard: true
    → Set Interactable Objects (["connector"], true)

  transitions:
    - event: "connector-secured"
      target: "ConnectionComplete"

  onExit:
    → Hide Panel
    → Remove Tool (Hand: "both")

A tool is attached to both hands for two-handed handling, then removed after the step.

Safety Equipment Attachment

State: FireSafetyResponse
  onEntry:
    → Attach Tool (Tool Asset: "fire-extinguisher", Hand: "right")
    → Show Panel
        Title: "Fire Emergency Response"
        Display Text: "You are holding a fire extinguisher. Know the PASS technique: Pull, Aim, Squeeze, Sweep."
        Billboard: true

  transitions:

      target: "SafetyConfirmed"

  onExit:
    → Hide Panel
