Constructor

Phaser. Time

new Time(game)

This is the core internal game clock.

It manages the elapsed time and calculation of elapsed values, used for game object motion and tweens, and also handles the standard Timer pool.

To create a general timed event, use the master Phaser.Timer accessible through events.

There are different types of time in Phaser:

  • Game time always runs at the speed of time in real life.

    Unlike wall-clock time, game time stops when Phaser is paused.

    Game time is used for timer events.

  • Physics time represents the amount of time given to physics calculations.

    When slowMotion is in effect physics time runs slower than game time. Like game time, physics time stops when Phaser is paused.

    Physics time is used for physics calculations and tweens.

  • Wall-clock time represents the duration between two events in real life time.

    This time is independent of Phaser and always progresses, regardless of if Phaser is paused.

Parameters
Name Type Description
game Phaser.Game

A reference to the currently running game.

Source code: time/Time.js (Line 38)

Public Properties

advancedTiming : boolean

If true then advanced profiling, including the fps rate, fps min/max, suggestedFps and msMin/msMax are updated.

Source code: time/Time.js (Line 165)

desiredFps : integer

The desired frame rate of the game.

This is used is used to calculate the physic / logic multiplier and how to apply catch-up logic updates. The desired frame rate of the game. Defaults to 60.

Source code: time/Time.js (Line 596)

<internal> desiredFpsMult : integer

The desiredFps multiplier as used by Game.update.

Internal:
  • This member is internal (protected) and may be modified or removed in the future.
Source code: time/Time.js (Line 126)

<internal> elapsed : number

Elapsed time since the last time update, in milliseconds, based on now.

This value may include time that the game is paused/inactive.

Note: This is updated only once per game loop - even if multiple logic update steps are done. Use physicsTime as a basis of game/logic calculations instead.

Internal:
  • This member is internal (protected) and may be modified or removed in the future.
Source code: time/Time.js (Line 86)
See
  • Phaser.Time.time

<internal> elapsedMS : integer

The time in ms since the last time update, in milliseconds, based on time.

This value is corrected for game pauses and will be "about zero" after a game is resumed.

Note: This is updated once per game loop - even if multiple logic update steps are done. Use physicsTime as a basis of game/logic calculations instead.

Internal:
  • This member is internal (protected) and may be modified or removed in the future.
Source code: time/Time.js (Line 99)

events : Phaser.Timer

A Phaser.Timer object bound to the master clock (this Time object) which events can be added to.

Source code: time/Time.js (Line 245)

[readonly] fps : number

Advanced timing result: Frames per second.

Only calculated if advancedTiming is enabled.

Source code: time/Time.js (Line 183)

fpsMax : number

Advanced timing result: The highest rate the fps has reached (usually no higher than 60fps).

Only calculated if advancedTiming is enabled. This value can be manually reset.

Source code: time/Time.js (Line 201)

fpsMin : number

Advanced timing result: The lowest rate the fps has dropped to.

Only calculated if advancedTiming is enabled. This value can be manually reset.

Source code: time/Time.js (Line 192)

[readonly] frames : integer

Advanced timing result: The number of render frames record in the last second.

Only calculated if advancedTiming is enabled.

Source code: time/Time.js (Line 174)

<internal> game : Phaser.Game

Local reference to game.

Internal:
  • This member is internal (protected) and may be modified or removed in the future.
Source code: time/Time.js (Line 44)

msMax : number

Advanced timing result: The maximum amount of time the game has taken between consecutive frames.

Only calculated if advancedTiming is enabled. This value can be manually reset.

Source code: time/Time.js (Line 220)

msMin : number

Advanced timing result: The minimum amount of time the game has taken between consecutive frames.

Only calculated if advancedTiming is enabled. This value can be manually reset.

Default Value
  • 1000
Source code: time/Time.js (Line 211)

<internal> now : number

An increasing value representing cumulative milliseconds since an undisclosed epoch.

While this value is in milliseconds and can be used to compute time deltas, it must must not be used with Date.now() as it may not use the same epoch / starting reference.

The source may either be from a high-res source (eg. if RAF is available) or the standard Date.now; the value can only be relied upon within a particular game instance.

Internal:
  • This member is internal (protected) and may be modified or removed in the future.
Source code: time/Time.js (Line 72)

pauseDuration : number

Records how long the game was last paused, in milliseconds. (This is not updated until the game is resumed.)

Source code: time/Time.js (Line 227)

physicsElapsed : number

The physics update delta, in fractional seconds.

This should be used as an applicable multiplier by all logic update steps (eg. preUpdate/postUpdate/update) to ensure consistent game timing. Game/logic timing can drift from real-world time if the system is unable to consistently maintain the desired FPS.

With fixed-step updates this is normally equivalent to 1.0 / desiredFps.

Source code: time/Time.js (Line 112)

physicsElapsedMS : number

The physics update delta, in milliseconds - equivalent to physicsElapsed * 1000.

Source code: time/Time.js (Line 119)

<internal> prevTime : number

The now when the previous update occurred.

Internal:
  • This member is internal (protected) and may be modified or removed in the future.
Source code: time/Time.js (Line 58)

slowMotion : number

Scaling factor to make the game move smoothly in slow motion

  • 1.0 = normal speed
  • 2.0 = half speed
Default Value
  • 1
Source code: time/Time.js (Line 158)

suggestedFps : number

The suggested frame rate for your game, based on an averaged real frame rate. This value is only populated if Time.advancedTiming is enabled.

Note: This is not available until after a few frames have passed; until then it's set to the same value as desiredFps.

Source code: time/Time.js (Line 149)

<internal> time : integer

The Date.now() value when the time was last updated.

Internal:
  • This member is internal (protected) and may be modified or removed in the future.

<internal> timeExpected : number

The time when the next call is expected when using setTimer to control the update loop

Internal:
  • This member is internal (protected) and may be modified or removed in the future.
Source code: time/Time.js (Line 239)

<internal> timeToCall : number

The value that setTimeout needs to work out when to next update
