constructor
Creates a new counter
Returns PerfCounter
Properties
Static EnabledSearch playground for Enabled
Gets or sets a global boolean to turn on and off all the counters
Accessors
average
Returns the average value since the performance counter is running
Returns number
count
Gets the total value count
Returns number
current
Returns the current value
Returns number
last Sec Average
Returns the average value of the last second the counter was monitored
Returns number
max
Returns the biggest value ever
Returns number
min
Returns the smallest value ever
Returns number
total
Gets the accumulated total
Returns number
Methods
add CountSearch playground for addCount
Call this method to monitor a count of something (e.g. mesh drawn in viewport count)
Parameters
newCount: number
the count value to add to the monitored count
fetchResult: boolean
true when it's the last time in the frame you add to the counter and you wish to update the statistics properties (min/max/average), false if you only want to update statistics.
Returns void
begin MonitoringSearch playground for beginMonitoring
Start monitoring this performance counter
Returns void
end MonitoringSearch playground for endMonitoring
Compute the time lapsed since the previous beginMonitoring() call.
Parameters
Optional newFrame: boolean
true by default to fetch the result and monitor a new frame, if false the time monitored will be added to the current frame counter
Returns void
fetch New FrameSearch playground for fetchNewFrame
Call this method to start monitoring a new frame. This scenario is typically used when you accumulate monitoring time many times for a single frame, you call this method at the start of the frame, then beginMonitoring to start recording and endMonitoring(false) to accumulated the recorded time to the PerfCounter or addCount() to accumulate a monitored count.
Returns void
This class is used to track a performance counter which is number based. The user has access to many properties which give statistics of different nature.
The implementer can track two kinds of Performance Counter: time and count. For time you can optionally call fetchNewFrame() to notify the start of a new frame to monitor, then call beginMonitoring() to start and endMonitoring() to record the lapsed time. endMonitoring takes a newFrame parameter for you to specify if the monitored time should be set for a new frame or accumulated to the current frame being monitored. For count you first have to call fetchNewFrame() to notify the start of a new frame to monitor, then call addCount() how many time required to increment the count value you monitor.
