  2. Does Data Asset have information?

    • Is Character Name filled?
    • Is Character Icon assigned?

Stats Appear Incorrect

Problem: Stat values differ from expected.

Solutions:

  1. Check Data Asset:

    • Are Base Stats entered correctly?
    • Are multipliers 1.0-based? (1.3 = 130%)

  2. Check formatted text:

    • If using Get Character Stats Formatted, is format correct?
    • Is percentage conversion happening? (x100)

Player Not Spawning

Problem: Character selected but player doesn't spawn.

Solutions:

  1. Is Selected Character null?

    • Is character selection done correctly?
    • Is Selected Character variable set?

  2. Player spawn logic:

    • Is Spawn Player function correct?
