CLASS::AppClock
categories::Scheduling>Clocks
summary::Clock running on main application thread
related::Classes/SystemClock, Classes/TempoClock
DESCRIPTION::
SystemClock is more accurate, but cannot call Cocoa primitives. AppClock is less accurate (uses NSTimers) but can call Cocoa primitives.
You will need to use the link::Classes/SystemClock:: to get accurate/musical scheduling.
See link::Classes/Clock:: for general explanation of how clocks operate.
CLASSMETHODS::
private::initClass
method::sched
The float you return specifies the delta to resched the function for. Returning nil will stop the task from being rescheduled.
code::
(
AppClock.sched(0.0,{ arg time;
["AppClock has been playing for ",time].postln;
rrand(0.1,0.9);
});
)
::
code::
(
AppClock.sched(2.0,{
"2.0 seconds later".postln;
nil;
});
)
::
method::clear
Clear the AppClock's scheduler to stop it.
code::
AppClock.clear;
::
method::play
The link::Classes/Routine:: (or link::Classes/Task::) yields a float value indicating the delta (secs) for the AppClock to wait until resuming the Routine.
code::
(
var w, r;
w = Window.new("trem", Rect(512, 256, 360, 130));
w.front;
r = Routine({ arg appClockTime;
["AppClock has been playing for secs:",appClockTime].postln;
60.do({ arg i;
0.05.yield;
w.bounds = w.bounds.moveBy(10.rand2, 10.rand2);
w.alpha = cos(i*0.1pi)*0.5+0.5;
});
1.yield;
w.close;
});
AppClock.play(r);
)
::
method::tick
AppClock.tick is called periodically by the SuperCollider application itself. This updates the link::Classes/Scheduler:: and causes any scheduled tasks to be executed. You should never call this method yourself.
