1 00:00:01,840 --> 00:00:07,570 OK, so now we want to start messing around with time in our songs, so we want to get the total play 2 00:00:07,570 --> 00:00:09,040 length time of a song. 3 00:00:09,040 --> 00:00:10,360 We want to get the current time. 4 00:00:10,660 --> 00:00:14,770 We want to know at any given time how long the song has played and stuff like that. 5 00:00:14,770 --> 00:00:17,650 So we're going to start to do that in this video that's going to take us a few videos. 6 00:00:18,070 --> 00:00:21,540 It's not all that complicated, but we're going to have to do a little bit of coding for this. 7 00:00:21,550 --> 00:00:25,780 So the first thing we want to do is let's create a function. 8 00:00:27,530 --> 00:00:36,620 To deal with time and I'm going to call this define play, underscore time, and right now we're just 9 00:00:36,620 --> 00:00:37,310 going to pass. 10 00:00:37,520 --> 00:00:44,120 Now we want to call this function any time we start to play a song so we can call this function from 11 00:00:44,120 --> 00:00:45,080 our play function. 12 00:00:46,010 --> 00:00:52,370 So let's come down to our play function and here at the bottom, let's just say get song time and we 13 00:00:52,370 --> 00:00:56,000 could just call it like this, we call it the name of the function and then we put the parentheses. 14 00:00:56,210 --> 00:01:02,630 So any time we play a song, it will grab the song, do its stuff, add it to the mixer, start playing 15 00:01:02,630 --> 00:01:05,450 it, and then boom, call this play time function. 16 00:01:05,720 --> 00:01:08,150 So what do we want to do in this play time function? 17 00:01:08,330 --> 00:01:13,400 Well, first off, let's just grab whatever the current time is for our song. 18 00:01:13,410 --> 00:01:21,680 So let's call this current underscore time and we can do this by calling pygame mixer dot music. 19 00:01:21,680 --> 00:01:27,940 As always, dot get underscore PEOC that stands for position right now. 20 00:01:27,950 --> 00:01:30,220 This is a function now is kind of interesting. 21 00:01:30,230 --> 00:01:32,630 What is this returning. 22 00:01:32,960 --> 00:01:35,720 Is it returning seconds, milliseconds, minutes. 23 00:01:36,020 --> 00:01:38,460 What kind of time you type things. 24 00:01:38,660 --> 00:01:39,470 Is this returning. 25 00:01:39,660 --> 00:01:42,200 This is actually returning milliseconds. 26 00:01:42,380 --> 00:01:47,540 So actually let's come down to the very bottom here and let's grab our my label thing and let's use 27 00:01:47,540 --> 00:01:54,260 this again to output the current whatever onto the screen and and see what it see what it outputs. 28 00:01:54,290 --> 00:02:04,310 So up to our play time function and let's go my label dot config and set the text equal to current underscore 29 00:02:04,310 --> 00:02:04,860 time. 30 00:02:05,270 --> 00:02:12,500 Now when this when we play a song, the song will start and then this will get called and it'll get 31 00:02:12,500 --> 00:02:15,740 the current position which is basically zero or close to zero. 32 00:02:15,930 --> 00:02:18,550 So this will put something close to zero. 33 00:02:18,650 --> 00:02:20,990 We want this to refire. 34 00:02:21,020 --> 00:02:22,640 We want this function to. 35 00:02:23,670 --> 00:02:31,290 Sort of run itself every second so we can do that by, for instance, going my underscore label dot 36 00:02:31,290 --> 00:02:38,430 after and saying after a thousand milliseconds, which is one second after one second, run this play 37 00:02:38,430 --> 00:02:40,150 time function again. 38 00:02:40,530 --> 00:02:48,180 So basically what this will do is every second this function will run again and a second will have gone 39 00:02:48,180 --> 00:02:48,640 by. 40 00:02:48,660 --> 00:02:54,270 So another second will be the current position of the song will be a second later and then this will 41 00:02:54,270 --> 00:02:56,760 get output to that current time a second later. 42 00:02:56,880 --> 00:02:58,950 So every second this label will change. 43 00:02:58,980 --> 00:03:01,380 So let's go and save this and head back over here. 44 00:03:02,940 --> 00:03:05,880 And run the sky and run this guy. 45 00:03:06,860 --> 00:03:09,050 And let's add some songs you. 46 00:03:10,210 --> 00:03:17,860 And play one, so a thousand, two thousand, three thousand, four thousand, so you remember, these 47 00:03:17,860 --> 00:03:21,480 are milliseconds, so that's not all that useful. 48 00:03:22,030 --> 00:03:23,860 So we need to convert this. 49 00:03:23,860 --> 00:03:31,210 So let's head back over our code and see in our playtime thing, we can just take this number and divide 50 00:03:31,210 --> 00:03:31,990 it by a thousand. 51 00:03:32,860 --> 00:03:41,230 Now, this is still going to return a decimal, so it'll be one point zero four seconds, one point 52 00:03:41,290 --> 00:03:44,750 oh eight seconds, two point zero seven seconds, whatever. 53 00:03:44,950 --> 00:03:46,930 So we don't really want the decimals. 54 00:03:47,110 --> 00:03:49,750 So instead, let's convert this to an integer. 55 00:03:50,050 --> 00:03:52,030 And integers are just whole numbers. 56 00:03:52,030 --> 00:03:52,310 Right. 57 00:03:52,600 --> 00:03:56,790 So we could do this by wrapping this variable in an integer function. 58 00:03:56,850 --> 00:03:57,140 Right. 59 00:03:57,520 --> 00:04:01,680 So this was just rounded up or down or whatever and make it a whole number. 60 00:04:01,690 --> 00:04:04,390 So one second, two seconds, three seconds, etc.. 61 00:04:04,660 --> 00:04:07,630 So, OK, let's go ahead and run this and see what this looks like. 62 00:04:08,020 --> 00:04:08,920 Pull this over. 63 00:04:09,130 --> 00:04:10,450 Add a bunch of songs. 64 00:04:12,240 --> 00:04:20,120 Now, let's play one one second, two seconds, three seconds, four seconds, five seconds, pretty 65 00:04:20,360 --> 00:04:20,750 so. 66 00:04:23,210 --> 00:04:29,990 All right, we're starting to get somewhere here and close this, and that's useful, but it's still 67 00:04:29,990 --> 00:04:31,100 not super useful. 68 00:04:31,130 --> 00:04:38,090 We like time formats, like when you look at a watch, it's like or one 12 or two and thirty seconds 69 00:04:38,090 --> 00:04:40,190 and thirty five seconds, etc., stuff like that. 70 00:04:40,190 --> 00:04:44,480 So we can actually convert that number, that integer that we just saw on the label. 71 00:04:44,480 --> 00:04:49,400 One second, two seconds, three seconds to a time format and we'll look at that in the next video.
