new StandardClock(options: ClockOptions): StandardClock
Parameters
- options: ClockOptions
Returns StandardClock
Overrides Clock.constructor
- Defined in Util/Clock.ts:180

`Protected` tick

tick: ((elapsedMs: number) => any)

Type declaration

- (elapsedMs: number): any
- Parameters
  - elapsedMs: number
  Returns any

Methods

elapsed

elapsed(): number
Get the elapsed time for the last completed frame

Returns number
Inherited from Clock.elapsed
- Defined in Util/Clock.ts:55

isRunning

isRunning(): boolean
Returns if the clock is currently running

Returns boolean
Overrides Clock.isRunning
- Defined in Util/Clock.ts:184

now

now(): number

- Defined in Util/Clock.ts:62

schedule

schedule(cb: (() => any), timeoutMs?: number): void
Schedule a callback to fire given a timeout in milliseconds using the excalibur Clock

This is useful to use over the built in browser setTimeout because callbacks will be tied to the excalibur update clock, instead of browser time, this means that callbacks wont fire if the game is stopped or paused.
Parameters
- cb: (() => any)
  
  callback to fire
  - - (): any
    - Returns any
- timeoutMs: number = 0
  
  Optionally specify a timeout in milliseconds from now, default is 0ms which means the next possible tick
Returns void
Inherited from Clock.schedule
- Defined in Util/Clock.ts:95

setFatalExceptionHandler

      Returns any
Returns void
