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').

Function has a local variable that's never read

Why: You created a local variable '{var}' inside this function, but no node ever reads it after assignment. It's just dead code. Fix: Either: (a) delete the variable and the Set node that writes to it, or (b) add a Get '{var}' node and connect it to wherever you actually need the value (if this was an oversight).

Get

Reads a variable's current value. Drag a variable from the My Blueprint panel and choose Get.

Text Block

Displays read-only text in UMG. Use a Binding or Text variable to update at runtime.

GetDataTableRow — read a row from a DataTable by RowName

Exec outputs: 'Row Found' and 'Row Not Found'. OutRow type depends on the DataTable's row struct. RowName must match the row name in the DataTable asset exactly.
