Array Remove — remove element at index from array

Array_Remove — remove element at index from array

Array: build dynamic list, iterate, find and remove items

ADD: Array Add (Target Array=MyArray, New Item=newElement). READ: Array Get (Target Array=MyArray, Index=i) → use 'Item' output. FIND: Array Contains (returns bool) or Array Find (returns index, -1 if not found). REMOVE by index: Array Remove (Target Array=MyArray, Index=i). REMOVE by value: Array Remove Item (Target Array=MyArray, Item=value). ITERATE: ForEachLoop(Array=MyArray) → 'Array Element' output is the current item. LENGTH: Array Length (returns int). Key: Array nodes operate on the array BY REFERENCE — always connect the array variable directly.

RemoveFromParent — remove widget from the screen

DestroyActor — remove actor from the world

RemoveFromParent — remove widget from viewport

Array Clear — remove all elements from array

Array_Clear — remove all elements from array

Destroy Actor

Removes an Actor from the world. References to it become invalid — use IsValid before dereferencing later.

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.
