Array element type doesn't match expected

Why: You're feeding an Array<{elem}> into a function that expects Array<{other}>. UE5 doesn't auto-cast array element types element-by-element — you'd lose type safety. Fix: Either: (a) change one array's variable type to match (My Blueprint → variable → Details → Variable Type → set to Array of {other}), or (b) loop over the source array, cast each element individually, and Append to a new typed array. Use the ForEachLoop node for this.

Array Get — get element at index from array

Pure node. Does NOT bounds-check — will throw if Index >= array length.

Array Contains — check if array contains a specific element

Pure node. Input pin is 'Item To Find In Array' (includes spaces).

Array_Add — add element to end of array

UKismetArrayLibrary::Array_Add. Returns new index.

Array_Contains — check if array contains element

Array Remove — remove element at index from array

Array_Find — find index of element in array

Returns -1 if not found.

Set (Collection)

An unordered collection with unique elements. (The Set node for writing variables is a separate concept — see the entry for 'Set'.)
