Spell System – Ability Cast with Mana Cost (Infravision)

Overview

Showcase a reusable spell framework that validates and consumes mana on cast, then runs a timed gameplay effect with clean VFX lifecycle handling.

Key points

• Base Spells class provides shared validation and mana cost (CanCast() + TryCast())

• Spell-specific behavior implemented via OnCast() in derived classes

• Infravision uses a timed coroutine: enable VFX → wait(duration) → disable VFX

• UI updates through a simple mana bar binding (magicNow / maximumMagic)

Architecture Overview

Architecture Overview

Character (base)

 ├─ magicNow / maximumMagic

 └─ (UI reads current mana)

Spells (base)

 ├─ duration / magicCost

 ├─ CanCast() → validates mana

 └─ TryCast() → consumes mana + calls OnCast()

InfravisionSpell : PlayerSpells

 ├─ PlayCastVFX()

 └─ InfravisionRoutine() → enable VFX → wait(duration) → disable VFX

ManaBar (UI)

 └─ fillAmount = magicNow / maximumMagic

Execution Flow

VALIDATE → CONSUME → CAST VFX → ENABLE → WAIT → DISABLE
