API

AccelTween = AccelTween.new(number maxaccel = 1) maxaccel is the maximum acceleration applied to reach its target.

number AccelTween.p Returns the current position. number AccelTween.v Returns the current velocity. number AccelTween.a Returns the maximum acceleration. number AccelTween.t Returns the target position. number AccelTween.rtime Returns the remaining time before the AccelTween attains the target.

AccelTween.p = number Sets the current position. AccelTween.v = number Sets the current velocity. AccelTween.a = number Sets the maximum acceleration. AccelTween.t = number Sets the target position. AccelTween.pt = number Sets the current and target position, and sets the velocity to 0.
