类 Timer

En

The Timer class is responsible for time management. It is a singleton and should not be instantiated manually. Access it via Laya.timer

Zh

Timer 是时钟管理类。它是一个单例，不要手动实例化此类，应该通过 Laya.timer 访问。

frameLoop

  • frameLoop(
        delay: number,
        caller: any,
        method: Function,
        args?: any[],
        coverBefore?: boolean,
    ): void

    Repeatedly executes at frame intervals.

    参数

    • delay: number

      The interval time in frames.

    • caller: any

      The scope of the object (this).

    • method: Function

      The callback function to be executed by the timer.

    • 可选args: any[]

      The arguments to pass to the callback function.

    • 可选coverBefore: boolean

      Whether to overwrite previous delayed execution, default is true.

    返回 void

    Zh

    定时重复执行（基于帧率）。

frameOnce

  • frameOnce(
        delay: number,
        caller: any,
        method: Function,
        args?: any[],
        coverBefore?: boolean,
    ): void

    Executes once after a delay in frames.

    参数

    • delay: number

      The delay time in frames.

    • caller: any

      The scope of the object (this).

    • method: Function

      The callback function to be executed by the timer.

    • 可选args: any[]

      The arguments to pass to the callback function.

    • 可选coverBefore: boolean

      Whether to overwrite previous delayed execution, default is true.

    返回 void

    Zh

    定时执行一次（基于帧率）。

loop

  • loop(
        delay: number,
        caller: any,
        method: Function,
        args?: any[],
        coverBefore?: boolean,
        jumpFrame?: boolean,
    ): void

    Repeatedly executes at intervals.

    参数

    • delay: number

      The interval time in milliseconds.

    • caller: any

      The scope of the object (this).

    • method: Function

      The callback function to be executed by the timer.

    • 可选args: any[]

      The arguments to pass to the callback function.

    • 可选coverBefore: boolean

      Whether to overwrite previous delayed execution, default is true.

    • 可选jumpFrame: boolean

      Whether to jump frames. For time-based callbacks, if multiple callbacks can be executed within a given time interval, the engine defaults to executing once for performance reasons. Setting jumpFrame to true will allow multiple executions in quick succession.

    返回 void

    Zh

    定时重复执行。

once

  • once(
        delay: number,
        caller: any,
        method: Function,
