Sounds About Right6:08 with Craig Dennis
You can add sounds very easily to a JavaFX application. Let's add some without being annoying.
As we saw in that user story, 0:00 we want to notify the user when the break is finished. 0:02 I think we should also commend their effort. 0:05 They achieved 25 minutes of focus time. 0:07 They deserve a round of applause. 0:10 Let's go figure out how to do that. 0:12 So before we get started, we better go take a look at the board. 0:14 It's a bit of a traffic jam, right? 0:18 [LAUGH] Okay, so we can move this one over, right? 0:20 This one about detailing what was going on with the Pomodoro. 0:22 We can move this one over to done, cuz we did that. 0:26 We mocked out the save. 0:28 And hypothetically, we've completed this story, right, 0:30 about notifying them about the change? 0:35 Now, I want to do a little more than what was specified by the request. 0:37 That making sound part probably should be its own ticket, though, right? 0:41 And this is kind of out of the project scope that we had agreed upon. 0:45 If you imagine this sort of project planning through user stories, 0:49 you can probably also imagine that this sort of scope creep, or 0:52 additional changes outside of the plan, happens all the time. 0:55 Now sometimes it happens outside the project. 0:58 People ask you, can you also make the app do this thing, please? 1:00 And sometimes it happens internally, right? 1:05 We developers see something that would make something way better. 1:07 Now, the way to handle to handle this is to discuss, both with your team and 1:11 the stakeholders of the project. 1:15 It's possible that the thing that we're going to add is way lower priority 1:17 than what the client wants to build. 1:21 And that the added work is gonna make us miss our deadline that we agreed upon when 1:23 starting this work. 1:26 Anyways, the best thing to do is to communicate. 1:28 As we're in a simulation here, I've talked it over with the powers that be and 1:32 everyone's on board with adding the applause sound. 1:36 Now our pretend stakeholders think it's a great feature. 1:39 Plus, wait till you see how easy it is to add noises. 1:42 Now, I talked to our pretend development team and 1:45 I told them that we could probably knock this out in five minutes, right? 1:47 And now I just need to figure out how to do it. 1:50 Shh. 1:53 Okay, so I'm gonna use my favorite search engine to look about how to 1:54 add sounds to a JavaFX 8 application. 2:00 Perfect, so there's a bunch of stuff that's showing up. 2:07 There's some game tutorial stuff. 2:09 You'll see some old things that came up even though I have JavaFX 8. 2:10 So let's be careful of that. 2:12 Here's one that says audio clip. 2:14 Let's open that up. 2:15 Okay, so this is the Java doc for an audio clip and 2:17 it represents a segment of audio that can be played with minimal latency. 2:19 Sounds great. 2:22 Playback we have here is fire and forget. 2:24 It loads in memory and it's for just really quick ones. 2:26 It's not efficient for long clips, especially if they're compressed. 2:29 So let's just go ahead and we will do that. 2:33 And if you look here, it shows all you need to do is call it. 2:36 And it's giving it an outside URL. 2:38 Which is okay. 2:41 But, we kind of want ours to work without the internet, right? 2:42 We want to get it to run offline. 2:46 I definitely want to be able to focus when I'm somewhere without the internet. 2:48 You know, like on an airplane that doesn't have wi-fi. 2:51 Those still exist, right? 2:55 Okay. 2:57 So, you get a handle on it, and you call play. 2:57 So here at Treehouse we use a tool call Sound Snap. 3:00 And I went and I found an applause mp3 and I downloaded it and 3:04 I've added it to the teacher's note. 3:07 So why don't you download it now, and I'm gonna jump over and 3:09 in my resources directory I'm gonna make a new directory for sounds. 3:13 Great. 3:21 And I'm going to open up my download folder. 3:22 All right so here's my downloads and I've downloaded the applause mp3. 3:25 I'm going to drag that into my sound folder here. 3:28 And of course it's going to talk about it, says do you want to move it? 3:31 Yes I do. 3:34 Says it doesn't belong, I want to do it anyway. 3:36 All right, okay. 3:40 So let's create one of these new audio clips that we just learned about. 3:42 Let's do it in the constructor of home. 3:45 In the constructor here we have this public home. 3:49 Let's go ahead and we'll just say mApplause = new AudioClip. 3:52 So we wanna use the javafx.scene.media.AudioClip, 4:01 is the one that we want, let's choose that. 4:04 And again we're gonna use that pattern. 4:06 We're gonna use the getClass of the object and we're gonna chain, and 4:08 we're gonna say, getResource. 4:11 We're gonna specify the resource that we want and again it's in the root there. 4:14 So we're gonna say /sounds/applause.mp3. 4:18 Now, it's expecting a URL. 4:23 Remember when we saw that HTTP one. 4:24 If we do this at the end here, 4:26 if we say toexternalform, what that will do is it will generate a file URL. 4:28 You've seen them before where it says file: and then the file all specified out. 4:32 What that does is that. 4:37 And now we have a working URL that the audio clip can hit. 4:38 We have not declared this yet. 4:41 Let's go ahead and say create field, right? 4:43 And it will pop up the private field audio clip here and it's nApplause. 4:46 Perfect. 4:51 Okay. 4:51 And then in the onFinished handler, now we could make a separate method for it. 4:52 I don't know if we need to just yet. 4:55 Let's hold off on that. 4:57 Let's go into this onFinished, right here, when this is all done. 4:59 Let's go ahead and let's play it. 5:03 So, we'll just call nApplause, and all we need to do is call play. 5:04 Awesome. 5:09 So, if we look back over in our AttemptKind, I believe that we left focus. 5:10 We're only at three seconds, right? 5:15 So, we've got to remember to flip that back. 5:16 So, focus is at three seconds. 5:18 So, let's go ahead, and let's run this. 5:19 Awesome, and we're gonna restart. 5:23 And when it finished, the applause is. 5:25 >> [APPLAUSE] >> [LAUGH] And we did it, blam. 5:28 Just made it and 5:33 I think we did it in the five minutes that we suggested that it would take, right? 5:34 So this is one of those times where you're probably going whoa, 5:37 I wonder what else this thing can do? 5:39 Well check the teacher's notes for more awesome. 5:41 Awesome, super easy right? 5:44 Now just because it's easy doesn't mean you need to go overboard. 5:46 Now I've some of these timers implement the clicking on each second like, [SOUND]. 5:50 Let's not do that, right. 5:56 But if you did, remember to make the [SOUND] only load once. 5:57 It seems like we have all the states defined that our stories would lead us to 6:01 believe are required. 6:05 What do you say we go ahead and wire it all up?
