Array_Add — add element to end of array

UKismetArrayLibrary::Array_Add. Returns new index.

Add_FloatFloat — add two floats

Pin names A, B, ReturnValue.

Array Add — add an element to the end of an array

Target Array is the array variable (pass by reference). Returns new array length.

Add_VectorVector — add two vectors

AddTag — add a tag to this actor

Inventory: add/remove items with array of structs

Create struct FInventoryItem: {ItemName (Name), ItemCount (int), ItemData (object ref)}. Variable: Inventory (Array<FInventoryItem>). AddItem: ForEachLoop(Inventory) → CastTo/Break FInventoryItem → Branch(ItemName==NewItem.Name) → True: Get → Modify Count → Array Set (replace at index) → return. If not found: Make FInventoryItem → Array Add. RemoveItem: Find by name → Branch(Count>1) → True: decrement → Set at index. Else: Array Remove at index. Key: Arrays of structs require 'Array Set' with index to modify in place — getting and modifying a copy does NOT update the array.

Add

Standard addition. Works on Integer, Float, Vector, Rotator, etc — UE picks the right overload from pin types.

AddImpulse — apply instant impulse to physics body

One-shot force. bVelChange=true treats Impulse as velocity change.

AddImpulse — apply an instant velocity change to a physics body

bVelChange=true treats Impulse as direct velocity change (ignores mass). bVelChange=false treats it as a force impulse (mass-dependent).

BooleanAND — logical AND

OR=BooleanOR, NOT=Not_PreBool, XOR=BooleanXOR
