このモジュールはパーティクルの色と透明度が生存期間の時間経過によってどう変化するかを設定します。
This module is part of the Particle System component. When you create a new Particle System GameObject, or add a Particle System component to an exiting GameObject, Unity adds the Color over Lifetime module to the Particle System. By default, Unity disables this module. To create a new Particle System and enable this module:
Since this module is part of the Particle System component, you access it through the ParticleSystem class. For information on how to access it and change values at runtime, see the Color over Lifetime module API documentation.
このセクション内の一部のプロパティでは、異なるモードを使用して値の設定が行えます。使用可能なモードについての詳細は、Varying properties over time を参照してください。
プロパティ | 機能 |
---|---|
Color | 寿命の時間経過で変わっていくパーティクルのカラーグラデーション。グラデーションバーの左端はパーティクルの寿命の開始点を示します。右端はパーティクルの寿命の終点を示します。 上の図で、パーティクルはオレンジ色で開始し、時間がたつにつれ色あせて透明度が増し、その寿命の終わりには見えなくなります。 |
さまざまな種類の自然な、または、幻想的なパーティクルの色は時間経過によって変化し、そのため、このプロパティには多くの利用方法があります。例えば、白くて熱いスパークは空気を走り抜けながら冷めるでしょうし、魔法の呪文は爆発して虹色になるかもしれません。しかし、同時に重要なことはアルファ(透明度)の変化です。パーティクルは寿命の終わりに近づくにつれて燃え尽き、消えたり散っていくのが一般的です(例えば、熱いスパーク、花火、煙のパーティクル)。簡易な衰退するグラデーションによってこの効果を生み出すことができます。
When also using the Start Color property, this module multiples the 2 colors together, to get the final particle color.
