Methods

cloneDecoration

  • cloneDecoration(action: ActionInterval): void

computeEaseTime

  • computeEaseTime(dt: any): any

reverseEaseList

  • reverseEaseList(action: ActionInterval): void

clone

easing

  • easing(easeObj: any): ActionInterval

  • 缓动运动。

    method

    easing

    example
    import { easeIn } from 'cc';
action.easing(easeIn(3.0));

    Parameters

    • easeObj: any

    Returns ActionInterval

getAmplitudeRate

  • getAmplitudeRate(): number

getDuration

  • getDuration(): number

  • 获取动作以秒为单位的持续时间。

    method

    getDuration

    Returns number

getElapsed

  • getElapsed(): number

getOriginalTarget

  • getOriginalTarget(): Node | null

getSpeed

  • getSpeed(): number

getTag

  • getTag(): number

getTarget

  • getTarget(): Node | null

initWithDuration

  • initWithDuration(d: number): boolean

isDone

  • isDone(): boolean

progress

  • progress(start: any, end: any, current: any, t: number): any

release

  • release(): void

repeat

  • repeat(times: number): ActionInterval

  • 重复动作可以按一定次数重复一个动作，使用 RepeatForever 动作来永远重复一个动作。

    method

    repeat

    Parameters

    • times: number

    Returns ActionInterval

repeatForever

  • repeatForever(): ActionInterval

  • 永远地重复一个动作，有限次数内重复一个动作请使用 Repeat 动作。

    method

    repeatForever

    Returns ActionInterval

retain

  • retain(): void

reverse

  • reverse(): this

setAmplitudeRate

  • setAmplitudeRate(amp: any): void

setDuration

  • setDuration(duration: number): void

  • 设置动作以秒为单位的持续时间。

    method

    setDuration

    Parameters

    • duration: number

    Returns void

setOriginalTarget

  • setOriginalTarget(originalTarget: any): void

setSpeed

  • setSpeed(speed: number): ActionInterval

setTag

  • setTag(tag: number): void

setTarget

  • setTarget(target: Node): void

speed

  • speed(speed: number): Action

  • 改变一个动作的速度，使它的执行使用更长的时间（speed > 1）
    或更少（speed < 1）可以有效得模拟“慢动作”或“快进”的效果。

    Parameters

    • speed: number

    Returns Action

startWithTarget

  • startWithTarget(target: {}): void

step

  • step(dt: number): void

stop

  • stop(): void

update

  • update(t: number): void
