Returns the animation's amount of alpha (opacity) change. A region's alpha value can be between 0 (fully transparent) and 1 (fully opaque); thus, an animation which changes alpha by 1 will always increase the region to full opacity, regardless of the region's existing alpha (and an animation whose change amount is -1 will reduce the region to fully transparent).

Signature:

change = Alpha:GetChange()

Returns:

  • change - Amount by which the region's alpha value changes over the animation's duration (between -1 and 1) (number)
