Hi,
I have an object which is moving towards the spline.
How would I find the intersection point of my object's forward vector and the spline (projected on the xz plane)?
So basically, I want to find out where my moving object is going to hit the spline when it moves forward.
Thank you

Hi
You can find an API method
here that gives you the nearest point of a ray from a spline. Once you get that point, check if that point is part of the ray or not to know if the ray indeed intersects the spline.
Did this help?
Have a nice day

Hi,
I did not find any method with a Ray as an input.
Thanks.

It's in the post I post the link for. That post contains code you need to add to two files, and the method is GetNearestPointTF(Ray ray, .....)
Is it clear now?

Ah, I missed the link. Thank you.
I integrated the code you posted on the other thread. The member mStepSize is not on CurvySplineSegment any more. How can I fix this?
Thank you!

Hi
mStepSize was a private member that was removed since. I updated the code in the referenced post to make it work without the mStepSize member: I replaced it's value with:1f / CacheSize
Please let me know if you find any issue.
Have a nice day
