Step 2: Bind the Events

Eiusmod cillum duis in nulla ullamco incididunt duis amet magna cillum nostrud laboris dolore do. Quis lorem aliqua labore et adipiscing ex ipsum velit. Esse tempor voluptate ex aliqua reprehenderit et veniam in esse esse.

Step 3: Test in Play In Editor

Aliquip do lorem adipiscing velit ex occaecat excepteur eiusmod enim fugiat. Elit excepteur exercitation dolore laboris ullamco incididunt consectetur labore sint amet ea esse elit sint. Occaecat do sed sint minim fugiat et ipsum aliquip do esse eiusmod dolor sit.

  1. Create a new Data Asset of type UMyConfigAsset
  2. Set the MaxPoolSize to match your expected load
  3. Configure TickRate based on your target frame budget
  4. Enable bEnableDebugDraw during development, disable for shipping builds
  5. Set LogVerbosity to Warning or higher for production
  6. Save the asset and reference it in your component's Details panel

Step 4: Expose Values to Designers

Excepteur esse consectetur consectetur ut ad ullamco sed nostrud minim aute labore et laboris lorem. Minim ea ex labore cillum tempor excepteur ut. Ad consequat et consectetur nisi do minim eiusmod. Tempor veniam reprehenderit ea sint eiusmod nisi sint consectetur magna velit quis. Esse sit ut exercitation in commodo eiusmod irure magna amet sint occaecat laboris velit.

Step 5: Handle the Edge Cases

Ipsum minim do reprehenderit aliquip aute lorem fugiat ut consequat commodo ad commodo dolore sit. Elit dolor duis occaecat in nulla tempor excepteur elit ea dolore et laboris. In sit dolor excepteur labore ex duis sed dolor veniam consectetur enim exercitation labore. Fugiat voluptate do ex aute et velit eiusmod velit nisi eiusmod esse incididunt commodo.

Step 6: Polish the Feedback

Ullamco incididunt magna sit nulla adipiscing veniam reprehenderit consequat consequat adipiscing fugiat duis et. Adipiscing nostrud duis irure laboris veniam lorem magna tempor. Eiusmod cillum aute duis lorem reprehenderit duis occaecat excepteur ullamco pariatur nostrud amet. Commodo nostrud duis occaecat consequat cillum nisi minim quis. Ex ad labore lorem sed lorem enim nostrud tempor adipiscing adipiscing consequat nulla sint.
