I'm setting up the mouse scroll wheel to zoom the camera in and out for a top-down game. I've gotten the input action setup to use the mouse wheel axis in the input context mapping, however in my OnZoomTriggered method I'm trying to find a method to get the scroll direction and velocity but I'm not seeing anything like that. For the left-click the template uses GetHitResultUnderCursor to get the click position, but I"m not seeing anything similar for the mouse scroll velocity. I'm trying to get the scroll velocity and increase or decrease the camera boom length based on that but I cannot find out how to get the mouse scroll velocity.
Does anyone know what I'm missing here?
