How to ignore widget components when checking hit result under cursor?

Development Programming & Scripting

Hit result under cursor relies on the Visibility Trace Channel (or camera).

Widget Component’s quad collision blocks pretty much that one thing only:

  • either add more channels that are not conflicting (in project settings)
  • or set the Collision Presets above to Custom and Ignore Trace Response Visibility / Camera (whichever you’re using for tracing)

Hi,

I have a actor with a screen space widget component , and in my bp steps I checked whether the actor is under cursor but strange thing is it return true even I am not clicking on the actor mesh.

As in the following pic, when I am clicking around the red area, it still gives me true…

After I digging into the code, I realized the widget component(used to display “InteractiveActor”) is being hit and it returns true with the hit actor being its owner.

I see in the function input parameters, inside the params, there are ignoreComponent option but I can not find a way to do so in blueprint.

My questions are:

  1. From the widget component side, is it possible to not involve in the hit result test?

  2. How to set the option ignore component when doing hit result under cursor?
