1 00:00:04,040 --> 00:00:09,770 Now that all of our core functionality is ready in our game, it's time to take the final steps of play 2 00:00:09,770 --> 00:00:12,680 testing, balancing and building our game. 3 00:00:13,340 --> 00:00:14,700 Before we jump into that low. 4 00:00:14,720 --> 00:00:20,060 We did add a bit of a bug in our last lecture when we were playing with our scorekeeper, because if 5 00:00:20,060 --> 00:00:25,240 we start the game now, when we click on our start button, nothing happens. 6 00:00:25,250 --> 00:00:30,260 Instead, we get an error message in our console and we're getting a null reference exception. 7 00:00:30,260 --> 00:00:33,290 So that's come out of play mode and fix this error. 8 00:00:33,410 --> 00:00:38,390 And one thing I want to show you with errors in the console is not only does it tell you what the problem 9 00:00:38,390 --> 00:00:38,810 is. 10 00:00:38,810 --> 00:00:44,210 So in this case, an object reference is not set to an instance of an object, so it's trying to access 11 00:00:44,210 --> 00:00:45,870 something that doesn't exist. 12 00:00:45,890 --> 00:00:51,350 It will also tell you the script and the method that's causing the problem and also the line where it's 13 00:00:51,350 --> 00:00:52,100 happening. 14 00:00:52,280 --> 00:00:56,930 And if we look at the stack trace down the bottom, we can ignore most of this. 15 00:00:56,930 --> 00:00:59,630 But we essentially read from the bottom up. 16 00:00:59,630 --> 00:01:04,930 And at the top it says that it's the level manager load level on line 18. 17 00:01:04,940 --> 00:01:10,470 And if we click on this link, it will open up our script and place us right at the problem area. 18 00:01:10,490 --> 00:01:15,950 So the problem here is we're trying to access a scorekeeper to reset the school, but there isn't actually 19 00:01:15,950 --> 00:01:18,650 a scorekeeper in our main menu scene yet. 20 00:01:18,650 --> 00:01:22,040 So the problem here doesn't really require a code fix. 21 00:01:22,040 --> 00:01:29,330 Instead, if we close our script, all we need to do is go to our prefabs folder, drag over our scorekeeper, 22 00:01:29,690 --> 00:01:36,890 and now if we hit play and test again, we should find that it works as expected and it does and takes 23 00:01:36,890 --> 00:01:38,120 us into our game. 24 00:01:38,540 --> 00:01:44,090 So with that small bug fixed, the next thing we want to think about is the balancing and play testing 25 00:01:44,090 --> 00:01:44,920 of our game. 26 00:01:44,930 --> 00:01:49,790 So first of all, let's run through all of the scenes and have a think about what else we might need 27 00:01:49,790 --> 00:01:52,010 to add or change for each one. 28 00:01:52,190 --> 00:01:55,190 Our main menu is pretty much good to go. 29 00:01:55,220 --> 00:02:01,760 The only things of concern is the quit button, which won't work for certain platforms like WebGL. 30 00:02:01,760 --> 00:02:07,310 So if we're building to those platforms, we may actually want to go ahead and delete this button from 31 00:02:07,310 --> 00:02:08,389 our menu system. 32 00:02:08,509 --> 00:02:13,550 The other thing we need to think about is potentially adding a credits menu to our start screen. 33 00:02:13,850 --> 00:02:19,280 This would be as simple as adding a new button to our button group for our credits button, and then 34 00:02:19,280 --> 00:02:24,320 we could potentially link this to maybe a new canvas which would overlay on top of the one we already 35 00:02:24,320 --> 00:02:29,420 have and would give us a nice place to give thanks to anyone that helped with the project or credit, 36 00:02:29,420 --> 00:02:32,210 any providers of various assets we might have used. 37 00:02:32,210 --> 00:02:36,470 And with the knowledge you've gained from this section and previous sections, you should be able to 38 00:02:36,470 --> 00:02:38,630 implement that without any problems. 39 00:02:38,780 --> 00:02:42,230 So there are a couple of things to think about with our main menu. 40 00:02:42,260 --> 00:02:47,120 If we head over to our game over menu, I think this one is okay to leave as it is. 41 00:02:47,120 --> 00:02:49,850 It does everything it needs to and nothing else. 42 00:02:49,850 --> 00:02:56,060 But while we're here, one thing we may want to consider for both our main menu and our canvas is if 43 00:02:56,060 --> 00:03:00,230 we head over to the canvas itself and look down at our canvas scaler. 44 00:03:00,260 --> 00:03:06,710 We've given it a reference resolution and we've told it to match width or height, preferring the width. 45 00:03:06,710 --> 00:03:13,100 Now this is fine if we force our game to work in the nine by 16 aspect ratio, but depending on some 46 00:03:13,100 --> 00:03:19,220 of our build settings and what the player is playing on, this could potentially run us into some problems 47 00:03:19,220 --> 00:03:25,370 because if we imagine this screen favoring the width and the player is playing on a 16 by nine aspect 48 00:03:25,370 --> 00:03:30,770 ratio, we're essentially going to see this portion of the screen which is going to potentially cancel 49 00:03:30,770 --> 00:03:34,910 out our quit button on our main menu and our main menu button on the game over. 50 00:03:34,910 --> 00:03:37,370 And it's all just going to look a little bit wrong. 51 00:03:37,370 --> 00:03:39,020 So a couple of options here. 52 00:03:39,020 --> 00:03:45,230 We can instead opt to favor the height of the screen and this would then extend the sides of our screen 53 00:03:45,230 --> 00:03:47,600 or we could go ahead and leave that as is. 54 00:03:47,600 --> 00:03:52,910 And instead of force some of these settings in the project settings, we'll get on to project settings 55 00:03:52,910 --> 00:03:53,690 in a while though. 56 00:03:53,690 --> 00:03:55,940 So let's leave things as they are for now. 57 00:03:55,970 --> 00:03:58,250 It's just something to always be thinking about. 58 00:03:58,250 --> 00:04:02,990 If you've tried to build your game and it all looks a bit strange, try looking at the canvas scale 59 00:04:02,990 --> 00:04:08,150 of first because that's usually in my experience, the biggest problem with most of my projects. 60 00:04:08,240 --> 00:04:11,030 So finally, let's go over and look at our game. 61 00:04:11,300 --> 00:04:16,399 And in here we've got a whole bunch of things that we can tune and tweak, so let's run through them 62 00:04:16,399 --> 00:04:17,269 into. 63 00:04:17,420 --> 00:04:22,430 The first one will be our player and I've actually already gone away and done some additional balancing. 64 00:04:22,430 --> 00:04:26,750 So the values you see in this lecture will be different to ones from previous lectures. 65 00:04:26,750 --> 00:04:32,180 If we head to the player script, this was where we were controlling the speed of our movement and the 66 00:04:32,180 --> 00:04:33,920 constraints of the screen. 67 00:04:33,950 --> 00:04:37,280 So what I've done in here is just change the top padding. 68 00:04:37,280 --> 00:04:42,380 I've brought that up so that the player is constrained to the bottom half of the screen. 69 00:04:42,950 --> 00:04:46,700 Some of the things we may consider is looking at our circle colliders. 70 00:04:46,700 --> 00:04:51,500 So if you're finding that your collisions look a little bit off when you're hitting projectiles or other 71 00:04:51,500 --> 00:04:57,470 enemies, then do be sure to go in and check your collider parameters for your offset and your radius. 72 00:04:57,710 --> 00:05:02,690 I think my health is mostly okay, although we may want to bump that up a little bit for a longer playing 73 00:05:02,690 --> 00:05:03,170 experience. 74 00:05:03,670 --> 00:05:08,200 And from my player, I thought the shooting was mostly okay as well, so I've left that as it is. 75 00:05:08,470 --> 00:05:15,070 However, if we then turn to our enemies, these aren't in our scene, but they are in our prefab folder. 76 00:05:15,370 --> 00:05:21,610 I've gone ahead and added a new enemy type, so I've done this by just duplicating my existing enemy 77 00:05:22,030 --> 00:05:23,360 for each of my enemies. 78 00:05:23,380 --> 00:05:28,030 I've modified the health a little bit because I thought they were a little bit too difficult to kill. 79 00:05:28,030 --> 00:05:34,510 And I've also modified their score so we can see that enemy one has a lower health and a lower score. 80 00:05:34,630 --> 00:05:39,760 And finally on here for the Shooter script, I've gone in and tweaked some of these parameters as well. 81 00:05:39,790 --> 00:05:44,710 There is no exact science, though, and I definitely wouldn't recommend copying the numbers I've used 82 00:05:44,710 --> 00:05:49,060 here because your game may look, fill and play in a very different way. 83 00:05:49,420 --> 00:05:53,530 Finally, on the gameplay front, we've got the waves and the paths. 84 00:05:53,530 --> 00:05:56,840 So rather than just the two normal ones I had before. 85 00:05:56,860 --> 00:06:02,680 I've created a bunch more with different configurations for the path, look and feel, and I've also 86 00:06:02,680 --> 00:06:07,150 created a whole bunch of extra waves with different parameters and different enemies. 87 00:06:07,600 --> 00:06:12,520 And remember, once we've added more waves to our folder, we can add them to the game itself by going 88 00:06:12,520 --> 00:06:15,640 under the enemy spawn and filling out our list. 89 00:06:15,970 --> 00:06:21,010 The final things we really have the option to tweak is in our audio player, where we can control the 90 00:06:21,010 --> 00:06:23,680 volume of different aspects of our game. 91 00:06:23,680 --> 00:06:27,280 So we've got the music volume and the various special effects volumes. 92 00:06:27,280 --> 00:06:33,190 So again, try and balance these so that the music isn't overwhelming and in-your-face and the shooting 93 00:06:33,190 --> 00:06:35,560 doesn't get too annoying if it's happening a lot. 94 00:06:35,860 --> 00:06:40,540 But with everything set up, let's play my game and just see how it looks and feels compared to the 95 00:06:40,540 --> 00:06:41,530 last lecture. 96 00:06:44,150 --> 00:06:48,290 So we start off with exactly the same two waves as we did before. 97 00:06:48,800 --> 00:06:54,470 But once they've finished, we've now got some new waves, new enemies and different patterns we now 98 00:06:54,470 --> 00:06:55,550 have to figure out. 99 00:06:56,300 --> 00:07:01,640 And because the shooting has changed as well, we now have a lot more challenge in the game. 100 00:07:01,910 --> 00:07:05,380 And I'm thinking that this may be a little bit too challenging. 101 00:07:05,390 --> 00:07:11,270 So again, it would be a case of going back in tweaking those numbers a second, third or even fourth 102 00:07:11,270 --> 00:07:16,430 time until we get something that plays nice, feels right, and will be fun for the player. 103 00:07:17,510 --> 00:07:23,180 And whilst we're on the subject of play testing, it's worth remembering that as the game developer, 104 00:07:23,180 --> 00:07:29,210 you are inherently better at your game than anyone else is probably going to be, and as such, you're 105 00:07:29,210 --> 00:07:32,390 going to find the game much easier than it really is. 106 00:07:32,390 --> 00:07:38,210 So it always revives your expectation of the difficulty down to make it playable for other people. 107 00:07:38,600 --> 00:07:43,370 This is also why you're getting external play testers to help us out is important. 108 00:07:43,460 --> 00:07:48,530 With that said though, before we can give our game to play testers, we need to build it so that we 109 00:07:48,530 --> 00:07:49,480 can share it. 110 00:07:49,490 --> 00:07:54,980 So the final thing we want to do is look at how to build the project so we can share it with other people. 111 00:07:55,010 --> 00:08:00,590 So the first step is going to be to come up to file and then down to build settings. 112 00:08:00,740 --> 00:08:04,980 And remember, this is where we came to place the scenes in our build. 113 00:08:05,000 --> 00:08:09,060 But now let's look at the bottom half of this screen with all of the build settings. 114 00:08:09,080 --> 00:08:12,640 Over on the left, we can select a platform to build to. 115 00:08:12,650 --> 00:08:18,380 And depending on how you set up your initial unity install, you may or may not have some of these options 116 00:08:18,380 --> 00:08:19,330 in the list. 117 00:08:19,340 --> 00:08:23,730 At the very least though, you will have a PC, Mac and Linux standalone build. 118 00:08:23,750 --> 00:08:26,510 So from here we could go and build our game. 119 00:08:26,660 --> 00:08:31,910 But I did mention we were potentially going to have some issues with the canvas resolutions and things 120 00:08:31,910 --> 00:08:32,480 like that. 121 00:08:32,480 --> 00:08:38,390 So the way we're going to fix those is if we're heading to our player settings up at the top, we can 122 00:08:38,390 --> 00:08:41,090 set a whole bunch of information like our version number. 123 00:08:41,090 --> 00:08:43,700 We can set a company name and a load of stuff up there. 124 00:08:43,700 --> 00:08:49,550 But what we want to do is come down to our resolution and presentation and we can just roll that out. 125 00:08:49,550 --> 00:08:54,110 And under here we've got a whole bunch of parameters, most of which we can completely ignore. 126 00:08:54,110 --> 00:08:56,840 But the two of note are the top two here. 127 00:08:56,840 --> 00:09:02,240 So we can change the full screen mode and we can select things like full screen or windowed or things 128 00:09:02,240 --> 00:09:02,930 like that. 129 00:09:02,930 --> 00:09:06,350 And also the default is native resolution. 130 00:09:06,350 --> 00:09:13,340 So if we want to try and enforce some kind of resolution, we can uncheck this box and we can set a 131 00:09:13,340 --> 00:09:15,770 default screen width and screen height. 132 00:09:15,770 --> 00:09:19,400 So that's one way to help fix any resolution issues you might encounter. 133 00:09:19,400 --> 00:09:24,980 But rather than setting my game to full screen, I'm going to set it to windowed. 134 00:09:25,190 --> 00:09:27,170 That will get rid of that checkbox option. 135 00:09:27,170 --> 00:09:31,820 And now we'll only have the option to set the screen width and height by default. 136 00:09:31,820 --> 00:09:36,650 With those options set up though, we can now come out of our settings window and back to our build 137 00:09:36,650 --> 00:09:41,660 settings and to build the game we just need to hit build from here. 138 00:09:41,660 --> 00:09:44,450 We then need to select somewhere to build to. 139 00:09:44,450 --> 00:09:50,210 So in our Laser Defender project, let's right click and create a new folder for all of our builds. 140 00:09:50,390 --> 00:09:52,130 Let's call that the builds file. 141 00:09:52,130 --> 00:09:55,250 It doesn't really matter what it's called, but it's nice and descriptive. 142 00:09:55,250 --> 00:10:00,200 And then in here we're going to have a couple of subfolders for the different platforms that we're building 143 00:10:00,230 --> 00:10:00,680 to. 144 00:10:00,920 --> 00:10:05,660 This first one is going to be the standalone build, so we'll select that as our folder. 145 00:10:06,440 --> 00:10:11,310 And now Unity will start building our project depending on the size of the project. 146 00:10:11,330 --> 00:10:14,750 This could take anywhere from a few seconds to a few hours. 147 00:10:15,140 --> 00:10:17,360 In this case, it didn't take too long. 148 00:10:17,360 --> 00:10:22,550 And now that it's finished, it's opened up our folder structure again and we can see all of the files 149 00:10:22,550 --> 00:10:24,170 that are included in this build. 150 00:10:24,200 --> 00:10:27,350 So that's how to build a standalone version of your game. 151 00:10:27,350 --> 00:10:32,420 But when it comes to sharing with the wider world online, people don't tend to like downloading projects 152 00:10:32,420 --> 00:10:33,950 from unknown developers. 153 00:10:33,950 --> 00:10:41,270 So to make your game easier to share, let's head back into unity and instead change our build to WebGL. 154 00:10:41,300 --> 00:10:46,730 This will allow it to be embedded in web pages so that players can play it without having to download 155 00:10:46,730 --> 00:10:47,380 anything. 156 00:10:47,390 --> 00:10:50,630 So let's click on WebGL and switch our platform. 157 00:10:50,720 --> 00:10:54,490 This can take some time depending on the size of your project. 158 00:10:54,500 --> 00:10:59,000 So I'm going to sit and wait for this to work, and I'll be back with you in just a moment. 159 00:10:59,740 --> 00:11:00,200 Okay. 160 00:11:00,220 --> 00:11:05,530 My project has now changed over to be a WebGL build and we can see that's the case with our little unity 161 00:11:05,530 --> 00:11:06,280 logo there. 162 00:11:06,400 --> 00:11:11,440 But before we go ahead and build this project, there's another couple of things we want to fix with 163 00:11:11,440 --> 00:11:12,250 this build. 164 00:11:12,280 --> 00:11:17,980 So if we head down to player settings once again to load up our project settings window in here, the 165 00:11:17,980 --> 00:11:23,230 top of the screen will be the same as it was before, but things like the resolution and presentation 166 00:11:23,230 --> 00:11:24,890 options will all have changed. 167 00:11:24,910 --> 00:11:29,440 So in here we're going to want to set our default canvas width and height. 168 00:11:29,440 --> 00:11:33,490 And this came in by default for me as 960 by 600. 169 00:11:33,730 --> 00:11:39,970 This is actually a 16 by ten ratio and our game should really be nine by 16. 170 00:11:39,970 --> 00:11:42,970 So let's go ahead and change our default canvas size. 171 00:11:42,970 --> 00:11:48,610 And we could go with a smaller scale like this one, so maybe 540 by 960. 172 00:11:49,000 --> 00:11:55,420 And if we head down to the publisher settings, we want to change the compression format to disabled 173 00:11:55,420 --> 00:11:59,530 because a lot of sharing platforms don't like to have this compression in the build. 174 00:11:59,530 --> 00:12:04,130 So if we disable it, they can compress anything they need to on their end instead. 175 00:12:04,150 --> 00:12:10,510 With those two changes, mate, let's go ahead and close our project settings and then build our project 176 00:12:10,810 --> 00:12:12,000 in our builds folder. 177 00:12:12,010 --> 00:12:14,920 Let's create a new folder for our WebGL build. 178 00:12:15,190 --> 00:12:16,990 So we'll call this WebGL. 179 00:12:19,430 --> 00:12:22,540 And then once again, we just need to sit and wait for it. 180 00:12:22,550 --> 00:12:27,410 And while we're waiting for that to work, let's jump over to a site called Share My Game dot com, 181 00:12:27,410 --> 00:12:29,620 which is run by game dev dot TV. 182 00:12:29,630 --> 00:12:34,940 And this is a great place to share your games and your prototypes with other members of the community. 183 00:12:35,030 --> 00:12:40,190 If you've never used the platform before, then the first thing you're going to need to do is to sign 184 00:12:40,190 --> 00:12:41,300 in or sign up. 185 00:12:41,420 --> 00:12:45,200 I've already got an account, so I'm just going to sign in with my Google account. 186 00:12:45,320 --> 00:12:50,840 If this is your first time signing up, then you'll be presented with a whole bunch of options for selecting 187 00:12:50,840 --> 00:12:54,170 your username, setting up profile pictures and all that kind of stuff. 188 00:12:54,170 --> 00:12:59,990 But once you're done to upload a game, you can either come to the home page and click on upload game 189 00:13:00,230 --> 00:13:01,340 or at the top. 190 00:13:01,340 --> 00:13:04,400 Here in the corner we have the upload game like on here. 191 00:13:04,700 --> 00:13:10,160 If we click on this to upload our WebGL build, once it's finished, we're just going to need to drag 192 00:13:10,160 --> 00:13:13,310 our entire WebGL folder into this box. 193 00:13:13,490 --> 00:13:19,370 My game has now finished building, so I'm going to click and drag that over and it will prepare our 194 00:13:19,370 --> 00:13:20,480 upload for us. 195 00:13:20,510 --> 00:13:25,610 This may again take some time, but it's part of the process of getting your games out into the world. 196 00:13:25,880 --> 00:13:31,220 Once that's finished, though, we'll get a congratulations message to say that it has been uploaded 197 00:13:31,220 --> 00:13:32,120 and is pending. 198 00:13:32,120 --> 00:13:36,860 We'll get a sample of our game so we can make sure that everything's working as intended. 199 00:13:38,940 --> 00:13:39,660 At the top here. 200 00:13:39,660 --> 00:13:43,450 We're also going to have the option to delete our upload if we wanted to. 201 00:13:43,470 --> 00:13:48,990 So if anything's wrong and we don't want to put this version up, we can delete this version, go back 202 00:13:48,990 --> 00:13:53,280 to unity and make any tweaks we need to make and then re upload a new version. 203 00:13:53,850 --> 00:13:57,270 Finally, at the bottom, we're going to need to set up some parameters. 204 00:13:57,480 --> 00:14:02,130 Once we're done there, we can save our upload and then that will take us through the remainder of the 205 00:14:02,130 --> 00:14:03,360 uploading process. 206 00:14:03,540 --> 00:14:07,350 And I think that brings us onto your final challenge for this section. 207 00:14:07,620 --> 00:14:10,560 I want you to go ahead and add more content to your game. 208 00:14:10,560 --> 00:14:14,220 So that'll include things like different enemy types, more waves. 209 00:14:14,220 --> 00:14:19,230 And if you're already feeling up to it, you could add some extra functionality like power ups or things 210 00:14:19,230 --> 00:14:20,010 like that. 211 00:14:20,040 --> 00:14:24,090 I also want you to balance your game once you've added this additional content. 212 00:14:24,090 --> 00:14:27,750 So make sure that it all functions and make sure it's fun to play. 213 00:14:27,780 --> 00:14:31,980 And once you've finished balancing your game and you've had play testers, have a go at it as well. 214 00:14:32,010 --> 00:14:36,270 Go ahead and share your game with the community and show off all of your hard work. 215 00:14:36,420 --> 00:14:41,890 Ask the community for feedback on your project, on what you could do better or what should be changed. 216 00:14:41,910 --> 00:14:47,940 And finally, pay this generosity forward from the community by reviewing someone else's game. 217 00:14:48,090 --> 00:14:51,140 Remember, we are all in it together and we're all still learning. 218 00:14:51,150 --> 00:14:56,130 So don't just post your game and expect feedback from others if you're not yourself willing to give 219 00:14:56,130 --> 00:14:57,810 feedback for their projects. 220 00:14:57,930 --> 00:15:02,760 So I look forward to seeing where you've taken your version of Laser Defender, and I'll see you in 221 00:15:02,760 --> 00:15:06,230 the next lecture where we wrap up and review everything we've learnt. 222 00:15:06,240 --> 00:15:07,680 So I'll see you there.
