UnifyScale()

void TiltFive.UniformScaleTransform.UnifyScale ( )

protected

Synchronizes the component values of the game object's local scale vector (e.g. [1,2,3] becomes [3,3,3]).

The vector component with the most extreme deviation from the previous uniform scale vector will be selected. If the previous scale was [2,2,2] and the current scale is [5, 15, 50] then the result will be [50, 50, 50]. This also applies for negative values: [5, -20, 10] would result in [-20,-20,-20].
