2. Add the Component

1. Open any Actor Blueprint (like a character or AI pawn).
2. In the Components panel, click Add Component and choose SmartConeTrace.
3. Select it and adjust the settings in the Details panel:
4. Interval — how often the trace runs (e.g. every 0.25 seconds)
5. Length — how far the cone reaches
6. AngleDegrees — how wide the cone is
7. bCheckVisibility — enable if you want to ignore objects behind walls

SmartConeTrace component selected, with editable parameters like Interval, Angle, and Visibility settings.

3. Handle the Result

1. In the Components panel, right-click the SmartConeTrace component.
2. Choose Add Event → Add OnConeTraceResult.

This creates an event node that fires every time the trace runs. You can access both Hit Actors (overlap) and Visible Actors (line-of-sight) from the result struct.

Example of using the OnConeTraceResult event to handle both Hit and Visible actors.

4. Test It

1. Place the actor in the level.
2. Hit Play.
3. The cone will automatically trace and trigger the event.

If debug mode is enabled, you’ll see the trace shape, hit boxes, and impact points.
