Is there any way to control VInterp with the mouse wheel?

Hi!

I wondering if there is any way to control VInterp with the mouse wheel.

I want to do a piece of the movement every time the player move the mouse wheel up.

How can I do it?

Thanks.

VInterp interpolates from A to B by a factor every time you call it, which is in Everynone’s case not a constant value and stops interpolating after the first call.

This is one of the rare cases I actually use the Tick function instead to do the interpolation.

I’d store a target vector value like “TargetPosition”. Then every time I move the mouse wheel up or down I’d add a value like 15 or -15 to an axis on the target vector. On the Tick event I’d interpolate the the current position (SomeActor->GetActorLocation()) to the target position. This feels very smooth if used with input based camera zoom-in / zoom-out.

What if I told you that it works just fine? Axis inputs execute every frame.

There is no need for additional Tick + Gate, a single event is enough:

How to use mouse wheel as input?

This can be boiled down to a single event, no additional Gates or Tick needed: [image] How can I a constant value to the blueprint graph? For example, the value 1.0 or -1.0. Not sure why you’d need this but, to answer literally, you could: [image] Or: [image] Or: [image] But that’d be quite awkward to use unless you’re after some specific behaviour, of course. Who knows.

On the other hand, Gates are more than fine - you actually get to control stuff.

Oh you are right, apoligies. I assumed this was an Action event, not an axis event. Recently I replied to someone who mixed up the button-like behavior of a mouse wheel after using an axis event . In this case you could use an axis event instead of tick perfectly fine as it executes every frame anyway.

I think Mouse Wheel Up and Mouse Wheel Down are action events.

If you do not want to use an Axis event, @Roy_Wierer.Seda145’s suggestion is the way to go then. The event would set target value and the VInterpTo will take you there during Tick. You’d need a couple more nodes but the end result will be the same.

you can make an array of vectors (positions) and control the INDEX of that array with the mouse wheel then you can just Vinterp current position with array[index] position all the time.
