Lever Trigger

Interactive Lever Creation & Animation

• Lever’s Unique Functionality

• Can be thrown forwards/backwards
• Result controlled by player vs timer-based
• “Player decides state rather than automatic timeout”

• Visual Components Setup

• Core Components:

  Base model (flattened cube) Lever model (thin cube) Scene component as proxy/hinge

• Scene Component Solution:

  Acts as intermediary hinge point Starts at (0,0,0) for clean animation Solves pivot point issues

  • Prevents center-point rotation
  • Enables proper hinge movement

• Interaction Implementation

• Interface Setup

  Added BPI_Interact Verb set to “pull lever”

• Animation System:

  Timeline created:

  • 1 second length
  • Float position track (0,0 to 1,1)

  Rotation:

  • Uses RLerp for smooth transition
  • 0 to 90 degrees over timeline

  Direction Handling:

  • Forward = OnTriggered(true)
  • Backward = OnTriggered(false)

• State Management

• IsActive variable tracks current state
• Branch logic:

  If active: reverse movement If inactive: play forward

Created an interactive lever system using a scene component for smooth hinge animation. System allows for bi-directional movement with proper state tracking, providing a more complex trigger type than previous pressure pad or button implementations.
