frameLoop(delay, caller, method, argsopt, coverBefore)

Timed repeat execution (based on frame rate).
Parameters:
Name Type Attributes Default Description
delay int How many frames (frames per frame) are spaced?.
caller Object Execute domain (this).
method function Timer callback function.
args Array <optional>
 null args Callback parameter.
coverBefore Boolean Whether or not the previous delay execution is covered, defaults to true.

frameOnce(delay, caller, method, argsopt, coverBefore)

Timed execution (based on frame rate).
Parameters:
Name Type Attributes Default Description
delay int Delays several frames (frames per unit).
caller Object Execute domain (this).

loop(delay, caller, method, argsopt, coverBefore, jumpFrame)

Timed repeat execution.
Parameters:
Name Type Attributes Default Description
delay int Interval time (ms per unit).
caller Object Execute domain (this).
method function Timer callback function.
args Array <optional>
 null args Callback parameter.
coverBefore Boolean Whether or not the previous delay execution is covered, defaults to true.
jumpFrame Boolean The clock is skipping. Time based callback, in the unit time interval, if you can perform multiple callbacks, for performance reasons, the engine defaults to only once. After setting the jumpFrame=true, the callback is executed several times in succession
