このモジュールでは、生存期間にわたってパーティクル速度がどのように減衰するかを制御します。
プロパティー | 説明 |
---|---|
Separate Axes | 軸を X, Y, Z のコンポーネントに分けます。 |
Speed | パーティクルの速度制限を設定します。 |
Space | 速度制限がローカル空間、ワールド空間のどちらを指しているかを選択します。このオプションは Separate Axes が有効であるときのみ利用できます。 |
Dampen | 速度の制限範囲を超えると、パーティクルの速度を減衰します。 |
この効果はパーティクルを減速する空気抵抗をシミュレートするのにとても便利です。特に、減速するカーブは速度制限を時間経過とともに引き下げる時に役立ちます。例えば、爆発や花火の最初の爆発は大きな速度を持っていますが、それから放出されたパーティクルは空気を通過するにつれて、急速に減速します。
