WaitForSecondsConstructor

パラメーター

説明

スケール化した時間を使用して、指定した秒数の間コルーチンの実行を待ちます。

Create a yield instruction. Wait for seconds multiplied by Time.scaledTime. If seconds is set to 2.0f and Time.scaledTime is set to 0.5f, the wait is 4.0f (2.0f divided by 0.5f seconds). The example WaitForSeconds has a value of 1.0f. The second button changes Time.scaledTime to 4.0f. The cubes now move faster.

// WaitForSeconds example.
//
// Create three cubes. Press the "Move cubes normally" button to animate them.
// Press the "Move cubes quickly" button to animate them faster.
// Have WaitForSeconds wait for different amounts of time. The cubes
// move upward or downward one at a time.
