Vector3.Lerp

Description

直線上にある2つのベクトル間を補間します

from で from と to の間を補間します。これは最も一般的な 2点を終点としたライン上のある部分を見つけるために使用します。 （例えば、オブジェクトを2点の間で徐々に移動させる） 数は[0...1]の範囲に制限されます。 from = 0 の時は from を返します。 to = 1 の時は to を返します。 from = 0.5 の時は from と to の平均（ちょうど真ん中）を返します。

		// Fraction of journey completed = current distance divided by total distance.
		var fracJourney = distCovered / journeyLength;
		
		// Set our position as a fraction of the distance between the markers.
