2020 Roadmap Q&A - Core Engine & Creator Tools

About Splines: When?
Will they be backported to 2019 or are they 2020+?
Which features will it have? Need rotation along the spline, move along the spline in distance steps, move in relative steps [0…1], etc
Will they support various easing functions out of the box?
Will splines be usable on terrain / environment system, e. g. to create roads, rivers etc?
Will Unity make their own prefab placement along splines?
Will snapping be supported while moving a spline point, so that one e. g. doesn’t move a point below the terrain?
Parallel splines along a base splines? (e. g. you have a center spline and one left and right offset by a certain distance)
Catmull-Rom or Bezier?

This is most exciting!

Hi Rowlan,

• We are talking here of a new unified spline framework API. It will be used to gradually unify existing and new splines applications across unity for 2020+. We are not considering backporting to 2019 at the moment.

• Splines will have many generic features (like the ones you mentioned, thanks for the input) but also application specific features (splines for rivers might differ in some ways from camera path splines for example) that are not in the API per say.

• Definitely usable on terrain, this is our top priority use case actually.

• Conforming to terrain (snapping to surface with normal alignement) is going to be supported.

• Generic offsets and parallel constraints are in the plan but will come later in the case of splines.

• We are supporting

• Bezier

• Catmull Rom

• KB Spline

• Linear

And eventually:

• BSpline
• Hermite

Thanks for your questions!
