I’m trying to implement like that the outline of Actor is highlighting and at the same time mouse cursor is also changed, when mouse cursor is overlapping on the actor.
I write my codes like below. I can see mouse cursor, when I play. And the settings like “bShowMouseCurosr” or “bEnableMouseOverEvents” are working well. But When the cursor is overlapping over this Actor, nothing is happened and the shape of mouse cursor isn’t also changed as crosshairs at the start of play.
Could somebody give me advise, what I’m missing or did wrong?
I set Player Controller Class up as this below PlayerController class and Default Pawn class is just DefaultPawn on World Settings.
