Move a character along a spline while having movement left/right

[dorisgao]

Hi, I’m trying to create a situation where the player runs on a given spline path at a changeable speed but can maneuver from left to right to avoid obstacles. Right now I can get the character to follow a “path” spline with GetLocation at Distance Along Spline function, somone mentioned using offset on the y-axis, but I can’t figure out how to set up the blueprint for that.

Any tips and help? Thanks a lot!

Hi Dorisgao,

I think the problem you’re running into is that your characters location is being set every frame to be on the spline.

So I think a solution would be to have the ‘scene root’ follow the spline (like it already is) and change the location for certain objects in your pawn/character.

I tested this for just the camera, but It should work the same for a hierarchy of parent/child objects. (A mesh with a springarm child with a camera child for example)

Welcome to the forums, let us know if you have any more questions about this!

Hi Astrotronic,

Thanks, that is very helpful! I got it working now. One problem is that it will make a sharp transition to the

left or right. Is lerp the correct function to use here in order to make a smooth transition？I had set up the blueprint like this now. Thank you again!!!

Glad to hear it!

Making it smooth is naturally the next step.

FInterpTo is the node you’re looking for.
