Overlaps

Creating Interactive Coin Pickup

• Blueprint Setup

• New blueprint class: BP coin

• Components:

  • Static mesh (cylinder)

    Gold material Thinner shape for coin look

  • Rotating movement

    180 degrees/second on z-axis Makes coin spin continuously

• Collision & Positioning

• Collision settings

  • Change from “block all dynamic” to “overlap all”
  • Enables walking through object

• Position adjustment

  • Root at grid center
  • Mesh hovering above ground

    Move up to prevent floor clipping Creates floating effect

• Interaction Logic

• Event graph setup

  • Use actor begin overlap
  • Simple destroy actor node
  • “Destroys self when player walks through”

This system creates a basic pickup mechanic using overlaps and automatic destruction. The coin rotates continuously until player contact triggers its removal, demonstrating fundamental interaction principles.
