As a Roblox developer, it is impossible(?) to have nonlinear animation transitions within the Roblox animation system
Currently we only have the option of linear animation transitions (or none at all: 0 fade time?)
Unfortunately linear transitions can look quite nasty such as in this example:
I would most like it if we could define our own fade styles (through a callback function), or if we could use all of the traditional easing styles
The three traditional styles that I use the most are Sine In, Sine Out, and Back Out BUT I love spring animations
If I am wrong and it is currently possible to do nonlinear animation transitions (it really feels like it should be possible!!), then please correct me for a double solution to both this and a scripting support post ; P
