Notes from the video concerning debugging

  • 32 min : BP visualizer. Works only when game is running in editor. Right click on variable to make value’s visual.
  • Window > Developer tools > Blueprint Debugger > watch
    Show values of all selected variables.
    Faster solution Window > debug
  • 33.14 min; Visual logging. Enable in PB
    Window > Developer tools > Visual logger.
  • Ticking : add Nodes : Vislogtext, VislogBoxshape, Visloglocation, VislogSegment
  • Stat commands : Stat Game
  • While playing hit TAB. Stat Game of Dumpticks
  • 36.23 min Profiler Tool
  • Reference viewer. Right click on BP > Ref viewer
  • Size map. Right click on BP > Sizemap
  • Use child BP . Video
  • 47.48 min. In a function, never reference directly to content (material for example), because all referenced contact will be loaded with the BP. Reference with a variable.
  • 49.27 min, page 122: Dynamic asset loading use Async Load Asset.
  • Use maps : variable – mesh, page 123
