public static float MoveTowards (float current, float target, float maxDelta);


current 現在の値
target 移動先となる値
maxDelta 値に適用される最大の変更


current から target まで、maxDelta のスピードで移動します。

This is essentially the same as Mathf.Lerp but instead the function will ensure that the speed never exceeds maxDelta. Negative values of maxDelta pushes the value away from target.
