1 00:00:01,650 --> 00:00:08,400 OK, in this video, we want to start to move our slider a second at a time as the song plays, so as 2 00:00:08,400 --> 00:00:12,210 the song is 10 seconds and the slider will have moved 10 spots. 3 00:00:12,240 --> 00:00:12,500 Right. 4 00:00:12,840 --> 00:00:19,170 And since our slider length in the last video is the length of the song, as it goes a second along, 5 00:00:19,350 --> 00:00:24,500 it will just like naturally look correct, you know, as the song progresses. 6 00:00:24,510 --> 00:00:26,340 So that's how we're going to do in this video. 7 00:00:26,370 --> 00:00:31,650 So let's come down here, same play time function underneath what we did. 8 00:00:31,650 --> 00:00:35,650 And I put a comma here set slider linked to the song length from our last video, forgot to comment 9 00:00:35,650 --> 00:00:35,820 it. 10 00:00:36,060 --> 00:00:39,270 So let's create a new comment right now and let's say. 11 00:00:40,250 --> 00:00:46,100 Move slider along one second at a time. 12 00:00:47,000 --> 00:00:51,140 All right, so let's create a variable and I'm going to call it next underscore time, and I'm going 13 00:00:51,140 --> 00:00:55,520 to set that equal to the integer of what our slider is so long. 14 00:00:55,520 --> 00:00:57,500 Underscore, slider, dot, get. 15 00:01:00,570 --> 00:01:07,560 Let's say the song starts, we're at zero, so song slider, get that get is zero, we're converting 16 00:01:07,570 --> 00:01:10,320 into an integer because it was zero point zero. 17 00:01:10,320 --> 00:01:11,520 So that'll just be zero. 18 00:01:11,520 --> 00:01:11,760 Right. 19 00:01:11,790 --> 00:01:18,900 So the next time the next thing forward is going to be whatever that is in this case, zero plus one. 20 00:01:19,470 --> 00:01:19,670 Right. 21 00:01:19,790 --> 00:01:25,700 So remember, this play time function gets run every one second. 22 00:01:25,710 --> 00:01:34,140 So every second this function, it's run again and this will add one to whatever the slider was before. 23 00:01:34,380 --> 00:01:36,500 So now we just need to output this. 24 00:01:36,510 --> 00:01:38,580 Analysts say output. 25 00:01:41,070 --> 00:01:50,010 New time value to slider so we can call our slider, let's go song underscore slider dat config and 26 00:01:50,010 --> 00:01:55,140 then we want to set the value that's currently where our little slider thing is. 27 00:01:55,530 --> 00:01:58,710 We just set that equal to next, underscore our time. 28 00:01:59,980 --> 00:02:02,230 So let's go ahead and save this and run it. 29 00:02:04,760 --> 00:02:08,990 And we can see we're at zero now we can as songs. 30 00:02:10,870 --> 00:02:11,640 Play this 31 00:02:14,480 --> 00:02:19,240 this down, turn the volume down a little bit and you can see it's moving along. 32 00:02:19,240 --> 00:02:22,290 So here says eight seconds in here, nine seconds. 33 00:02:22,300 --> 00:02:25,690 And this number and this number seem to be matched up. 34 00:02:26,170 --> 00:02:31,790 If we look back at our code, that label is the current song, slider position. 35 00:02:32,050 --> 00:02:33,310 Get the current value. 36 00:02:33,310 --> 00:02:33,650 Right. 37 00:02:34,030 --> 00:02:36,800 So, OK, that seems to be working. 38 00:02:39,070 --> 00:02:40,840 Now, if we try and drag this. 39 00:02:45,380 --> 00:02:52,730 You can see it's at one 15, one 16, and that's here is the elapsed time, thirty, thirty nine seconds, 40 00:02:52,730 --> 00:02:55,220 which is not particularly correct. 41 00:02:55,220 --> 00:02:57,470 And if we hit pause, it keeps moving. 42 00:02:57,480 --> 00:03:04,670 So we need to make some error handling and stuff built into this to make sure this works correctly. 43 00:03:05,360 --> 00:03:10,480 So we've got some stuff that we need to do here, but at least now it's sort of doing something. 44 00:03:10,500 --> 00:03:14,630 It seems to be moving as the song is moving. 45 00:03:14,640 --> 00:03:16,610 But you see now it's double counting. 46 00:03:16,610 --> 00:03:19,100 So there's all kinds of stuff we hit stop. 47 00:03:19,490 --> 00:03:20,600 It keeps going. 48 00:03:20,600 --> 00:03:21,770 So we need to work on this. 49 00:03:21,770 --> 00:03:24,230 We'll start we'll get into all of this in the next video.
