Tween feature request?

Is there any reason we can select different combinations for the interpolation types?

Like its either in elastic, out elastic, or in out elastic. Why can't we have say in exponential, out elastic in the same tween selection?

Is there a coding issue, or is it because the possible combinations are too numerous to list?

I don't think a "in exponential, out elastic" tween can be automatically designed. Would it just paste exponential in for the first 50% and elastic for the second 50%? It might not line up, so it would jump in the middle.

Ok, so I guess that would be a code/math thing where the interpolations don't mix well.

I vaguely remember being interested in suggesting giving a user the ability to plug in their own easing formula somewhere, but didn't bother after guessing the utilization rate would probably be so low it wouldn't be worth wasting time on. Lerp with a timer are enough for anyone who wants that much control.

There are custom eases and an ease editor. It's not a formula tho, but isn't that still doing what you mean? oosyrag
