static fps :Number

Last measured fps rate.
This feature is disabled by default. Load and enable the DebugPanel plugin to use it.

static lastUpdate :Date

Last update time.
Use this value to implement frame prediction in drawing events, for creating smooth motion while running game update logic at a lower fps.

static tick :Number

Last game tick value.
Use this value to scale velocities during frame drops due to slow hardware or when setting an FPS limit. (See me.sys.fps) This feature is disabled by default. Enable me.sys.interpolation to use it.

See:

• me.sys.interpolation

Methods

static clearInterval(intervalID)

Clears the Interval set by me.timer.setInterval().

Parameters:

Name	Type	Description
intervalID	Number	ID of the interval to be cleared

static clearTimeout(timeoutID)

Clears the delay set by me.timer.setTimeout().

Parameters:

Name	Type	Description
timeoutID	Number	ID of the timeout to be cleared

static getDelta() → {Number}

Return elapsed time in milliseconds since the last update

Returns:

Number

static getTime() → {Number}

Return the current timestamp in milliseconds
since the game has started or since linux epoch (based on browser support for High Resolution Timer)

Returns:

Number

static setInterval(fn, delay, pauseableopt) → {Number}

Calls a function continously at the specified interval. See setTimeout to call function a single time.

Parameters:

Name	Type	Attributes	Default	Description
fn	function			the function to execute
delay	Number			the number of milliseconds (thousandths of a second) on how often to execute the function
pauseable	Boolean	<optional>	true	respects the pause state of the engine.

Returns:

Number -

The numerical ID of the timeout, which can be used later with me.timer.clearInterval().

static setTimeout(fn, delay, pauseableopt) → {Number}

Calls a function once after a specified delay. See me.timer.setInterval to repeativly call a function.

Parameters:

Name	Type	Attributes	Default	Description
fn	function			the function you want to execute after delay milliseconds.
delay	Number			the number of milliseconds (thousandths of a second) that the function call should be delayed by.
pauseable	Boolean	<optional>	true	respects the pause state of the engine.

Returns:

Number -

The numerical ID of the timeout, which can be used later with me.timer.clearTimeout().
