Registering Actors with the Tooltip System Using Dedicated Components

Add tooltip functionality to Actors without code using the LayeredTooltipDefaultComponent.
Note: This component serves as a sample/reference implementation and may not satisfy all requirements for production game projects. For greater control, extend the implementation using C++ or Blueprints directly.

1. Create an Actor.

   

2. Add any PrimitiveComponent. A Cube is used in this example.

3. Ensure collision is enabled for the PrimitiveComponent. Collision Query must be enabled for mouse-over detection.

4. Add LayeredTooltipDefaultComponent to the Actor.

This component automatically finds the Actor's first collision-enabled PrimitiveComponent and handles mouse-over events.

5. Select the component and configure tooltip information in the Details tab.

6. To use this functionality, the PlayerController must have bEnableMouseOverEvents enabled.

   

7. The Actor now displays tooltips. Use the bOverrideTooltipPositionInViewport flag to control tooltip positioning.
