Since we have bindings in the Project Settings → Engine - Input section to activate events on inputs. What exactly do click event keys do on the player controller?
I could not find a decent documentation explaining them.
In the starter content, for the top down controller, it had the left mouse button assigned, I removed it so there was no event keys - and saw absolutely no change in behaviour so it didn’t seem to do anything…

Can some one explain what they are please because events still trigger in the blueprints when using input actions so I don’t see the purpose for these event keys.
Thanks
Hey @PixelPlayer, welcome to the Unreal community!
Click Event keys are not tied directly to your input bindings, and enabling/disabling them will not affect any mouse buttons which are manually set in your inputs. Click Events are events which can be called for the function OnClicked; this is useful for games where you want to drag and drop actors in the world, for example.
A great example of how Click Events are used can be found in the Mouse Interface content example, which is available in the Samples section of the Unreal Engine launcher. You can also read more about this learning module here.
I hope this information helps, and again, welcome to the community!
