DataTable driven item database: read stats from table

SETUP: 1. Create struct FItemData: {Name(Name), Damage(float), Icon(Texture2D), Description(Text)}. 2. Create DataTable with row type FItemData. Add rows (Sword, Bow, Staff...). READ: GetDataTableRow(Table=DT_Items, RowName='Sword') → Row Found exec → BreakFItemData(OutRow) → use Damage, Name, etc. DYNAMIC READ (from variable): SetVariable(CurrentItemName='Bow') → GetDataTableRow(RowName=CurrentItemName) → same flow. LIST ALL: GetDataTableRowNames → ForEachLoop → GetDataTableRow per name → display. Key: GetDataTableRow exec outs are 'Row Found' and 'Row Not Found' (NOT 'then').

Pickup and collectible system with overlap trigger

Pattern: Pickup actor with SphereCollision(overlap), StaticMesh visual. OnComponentBeginOverlap → CastTo PlayerCharacter → Success: call AddScore/AddItem interface on player → PlaySoundAtLocation → SpawnEmitterAtLocation → DestroyActor(self). Set collision to OverlapOnlyPawn for performance.

Inventory system with array of structs for items

Pattern: Struct S_InventoryItem(ItemName:String, Quantity:int, Icon:Texture2D, bStackable:bool). Variable Inventory(Array<S_InventoryItem>). AddItem: ForEachLoop(Inventory) → Branch(Element.ItemName == NewItem.Name AND bStackable) → True: SET Element.Quantity += Amount. If not found: Array_Add(NewItem). RemoveItem: Find index → Branch(Quantity > 1) → True: decrement. False: Array_Remove.

DataTable

A spreadsheet-like asset holding rows of a struct type. Great for item catalogs, dialogue lines, level configs.

Texture2D

A 2D image asset used by Materials (color, normal, roughness maps) or UMG Images.

Select — choose value based on index or boolean

Pure node. Type-specific variants: SelectFloat, SelectInt, SelectVector, SelectObject, SelectString, SelectColor.

Name

A case-insensitive immutable string ID. Fast comparisons; used for tags, slot names, asset references.

Health and damage system with ApplyDamage and EventAnyDamage

Dealing damage: Event → ApplyDamage(TargetActor, BaseDamage, InstigatorController, DamageCauser, DamageTypeClass). Receiving: EventAnyDamage → Damage output → Subtract_FloatFloat(CurrentHealth, Damage) → FClamp(Result, 0, MaxHealth) → SET CurrentHealth → Branch(CurrentHealth <= 0) → True: DestroyActor. Initialize CurrentHealth=MaxHealth in BeginPlay.

OR Boolean — logical OR of two booleans
