Casting

Casting & Score System Implementation

• Player Character Score System

• Add score variable (integer)
• Create “add score” function

  Takes current score + points Set back to score variable Debug: Print string shows points gained

• Casting Process

• Problem: Other actor pin = actor object reference

  Can’t directly access first person character functions

• Solution: “Cast parent reference to child reference”

  Drag from other actor Cast to first person character Enables access to child object functions

• Coin Implementation

• Begin overlap event

  Cast other actor to first person character If successful:

  • Destroy actor
  • Add score (10 points)
• Cast failed pin

  Appears when inheritance not shared Not issue with actor objects

• Practical Applications

• Hide coins around level
• Create platforming challenges
• Use with:

  Door systems Button mechanics Puzzles Marketplace assets

Casting enables object type conversion for accessing specific functions, demonstrated through a coin collection system. This foundational concept allows for creation of score-based gameplay mechanics and level design.
