Constant Force は、リジッドボディ に一定力を素早く加えるためのユーティリティです。これは、初速を大きくせずに、加速を重視する場合、例えばロケットのようなワンショットのオブジェクトに最適です。
プロパティ | 機能 |
---|---|
Force | ワールド空間で適用される力のベクトル。 |
Relative Force | オブジェクトのローカル空間で適用される力のベクトル。 |
Torque | ワールド空間で適用されるトルクのベクトル。オブジェクトはこのベクトルを軸として 何度も 回り続けます。ベクトルの値が大きければ大きいほど早く回転します。 |
Relative Torque | ローカル空間で適用されるトルクのベクトル。オブジェクトが、このベクトル 周辺 で回転し始めます。ベクトルの値が大きいほど、回転が速くなります。 |
加速しながら前進するロケットを作成するには、Relative Force を正の Z 軸に沿って設定します。次に、リジッドボディの Drag プロパティを使用して、一定の最大速度を超えないようにします(Dragの値を大きくするほど、最大速度が下がります)。リジッドボディで、ロケットが常に軌道上にあるよう、重力をオフにします。
