Returns the result of smoothly interpolating the value of [param x] between [code]0[/code] and [code]1[/code], based on the where [param x] lies with respect to the edges [param from] and [param to].
The return value is [code]0[/code] if [code]x <= from[/code], and [code]1[/code] if [code]x >= to[/code]. If [param x] lies between [param from] and [param to], the returned value follows an S-shaped curve that maps [param x] between [code]0[/code] and [code]1[/code].
This S-shaped curve is the cubic Hermite interpolator, given by [code]f(y) = 3*y^2 - 2*y^3[/code] where [code]y = (x-from) / (to-from)[/code].

smoothstep(0, 2, -5.0) # Returns 0.0
smoothstep(0, 2, 0.5) # Returns 0.15625
smoothstep(0, 2, 1.0) # Returns 0.5
smoothstep(0, 2, 2.0) # Returns 1.0
[/codeblock]
Compared to [method ease] with a curve value of [code]-1.6521[/code], [method smoothstep] returns the smoothest possible curve with no sudden changes in the derivative. If you need to perform more advanced transitions, use [Tween] or [AnimationPlayer].
