Is there a blueprint function that allows the camera to move in a curve?

you can create a curve, or curve asset. after you reference that curve in blueprints you can get a value Y over X, the curve. another way with less control is to use an interp node which interpolates between vector A and B

[Mirro1871]

Do you mean using CurveVector?

[Roy_Wierer.Seda145]

Yes that’s for 3D, you can use it as 3D position over time

Can CurveVector pass arguments at runtime?

I made a guide awhile back showing how to do something like this:

Mini tutorial: Make a configurable custom camera shake using timeline

Here is a way that you can use a timeline to create a configurable camera shake event. Is this better or worse than using Unreal’s camera shake class? Probably just a bit different, but I find it a little less cumbersome overall and easier to get exactly the results that I want without as much time spent tweaking. The idea is that we create an assembly line that intakes Curve Assets and spits out a camera shake. What you’ll need: Reference to the desired camera a Timeline Reference to the…

Not sure what you mean by that, a curve is only data, it has no function. If you mean that you need to alter the shape of the curve with parameters, then yes you can. You read the value of the curve over time, then apply some formula after that.

For example:

BasePosition = Get the initial world position of camera actor, before animating.
AdditionalPosition = Curve asset value over time X.
NewCameraPosition = BasePosition + AdditionalPosition.

If you are looking for a way to build the curve itself procedurally then you have little use for a curve asset, but you could do something similar with the interp (interpolation) node.
