setLoopPoints |
Description Sets the loop points used when looping.Signature void setLoopPoints(int start, int stop) Parameters start — int: the start of the loop in millisecondsstop — int: the end of the loop in milliseconds Returns None Related AudioPlayerExample /** * This sketch demonstrates how to use <code>setLoopPoints</code> * using an <code>AudioPlayer</code>. Left-click with the mouse * to set the start point of the loop and right-click to set the * end point of the loop. You will likely find * there to be a break during loops while the code seeks from the * beginning of the file to the start of the loop. This seek time * can become quite noticable if you are using an mp3 file * because it will need to decode as it seeks. */ import ddf.minim.*; Minim minim; AudioPlayer snip; int loopBegin; int loopEnd; void setup() { size(512, 200, P3D); minim = new Minim(this); snip = minim.loadFile("groove.mp3"); textFont(loadFont("ArialMT-14.vlw")); } void draw() { background(0); fill(255); text("Loop Count: " + snip.loopCount(), 5, 20); text("Looping: " + snip.isLooping(), 5, 40); text("Playing: " + snip.isPlaying(), 5, 60); int p = snip.position(); int l = snip.length(); text("Position: " + p, 5, 80); text("Length: " + l, 5, 100); float x = map(p, 0, l, 0, width); stroke(255); line(x, height/2 - 50, x, height/2 + 50); float lbx = map(loopBegin, 0, snip.length(), 0, width); float lex = map(loopEnd, 0, snip.length(), 0, width); stroke(0, 255, 0); line(lbx, 0, lbx, height); stroke(255, 0, 0); line(lex, 0, lex, height); } void mousePressed() { int ms = (int)map(mouseX, 0, width, 0, snip.length()); if ( mouseButton == RIGHT ) { snip.setLoopPoints(loopBegin, ms); loopEnd = ms; } else { snip.setLoopPoints(ms, loopEnd); loopBegin = ms; } } void keyPressed() { snip.loop(2); } Usage Web & Application |
