SpeedLimit

Extension

Description

Some control sources run at very fast rates, which may cause too much CPU load by running triggered functions too often. SpeedLimit limits these by keeping a minimum time between updates, while making sure slower messages are executed immediately.

First code examples:// make a SpeedLimit class with an action and a minimum waittime: // its // and time and args for actually evaluated calls; // should always do very last message too. ( a = SpeedLimit( // the action: post triggered time since last action, // and the args coming into the function - here, a message countup/down { |...args| ("*** doit: " + [ (Main.elapsedTime - a.lastTime).round(0.001), args ]).postln }, // dt, the minimum time to wait before retriggering 0.1 ); ) // run test: messages speed up from 0.2 ... 0.01 // messages thin out as they get faster, // and the last message always happens ( fork { (5..100).do { |n| var dt = (1 / n).round(0.001); // " send: %, %\n".postf(n, dt); // this calls action with triggers filtered by speedlimit: a.filterValue(n); dt.wait; } }; )
