Time.time

説明

このフレームの開始する時間(Read Only)。ゲーム開始からの時間(秒)です。

Time.time is the amount of time in seconds that the application has been running for. It is read-only.

The application receives the current Time.time at the beginning of each frame, with the value increasing per frame. A time call per frame receives the same value. When called from FixedUpdate it returns the Time.fixedTime property.

Regular (per frame) calls should be avoided: Time.time is intended to supply the length of time the application has been running for, and not the time per frame.

The value of Time.time is undefined during Awake messages and will start after all messages are finished.
