1 00:00:04,160 --> 00:00:11,360 ‫So one thing to be aware of with live coding is that at the moment you can encounter some bugs when 2 00:00:11,360 --> 00:00:12,080 ‫using it. 3 00:00:12,080 --> 00:00:19,010 ‫So for example, suppose I wanted to add a new new property in to my moving platform. 4 00:00:19,010 --> 00:00:22,070 ‫I can go ahead and just copy the INT. 5 00:00:22,070 --> 00:00:24,950 ‫I'm just going to have a my int two in here. 6 00:00:24,950 --> 00:00:32,600 ‫Now I go ahead and faithfully according to the course use live coding to rebuild and see my new property. 7 00:00:32,600 --> 00:00:39,650 ‫And once that's done, go ahead and close the window and I might go ahead and update the moving platforms. 8 00:00:39,650 --> 00:00:46,370 ‫Property here might say, oh, I don't want it to be 99 here, I want it to be set to 300 instead. 9 00:00:46,370 --> 00:00:49,780 ‫And then I finish up for the day and I close down my editor. 10 00:00:49,790 --> 00:00:56,030 ‫However, what you may observe is that when you go ahead and relaunch the project and go to the outline 11 00:00:56,030 --> 00:00:59,420 ‫and look again for your moving platform, select it. 12 00:00:59,570 --> 00:01:03,320 ‫You'll see that, oh no, that new property has disappeared. 13 00:01:03,320 --> 00:01:10,790 ‫So what appears to have happened is that live coding only affected the change in the editor, but it 14 00:01:10,790 --> 00:01:13,670 ‫didn't make it permanent on disk. 15 00:01:13,670 --> 00:01:16,190 ‫It didn't kind of make it stay there. 16 00:01:16,190 --> 00:01:20,000 ‫So what you might be tempted to do is, okay, well, I'll just hit the live coding button again. 17 00:01:20,000 --> 00:01:26,000 ‫It's going to go ahead and rebuild and it's going to reintroduce my change, but you'll notice, oops, 18 00:01:26,000 --> 00:01:28,160 ‫it's reset it to the default value. 19 00:01:28,160 --> 00:01:31,790 ‫So I've lost that data that I had entered in here, which is no good. 20 00:01:31,790 --> 00:01:37,910 ‫So if you do find yourself in this situation where you've gone ahead and seem to have lost some data, 21 00:01:37,940 --> 00:01:44,540 ‫go ahead and close the editor straight away so that we don't save any of that lost data. 22 00:01:44,930 --> 00:01:52,250 ‫And then what you want to do is go over to Visual Studio code and control shift B to bring up the build 23 00:01:52,250 --> 00:01:56,210 ‫tasks and start your regular build task here. 24 00:01:56,420 --> 00:02:01,010 ‫Make sure it re compiles fully outside of the editor with the editor closed. 25 00:02:01,010 --> 00:02:08,030 ‫Then you can go back to your project file and open it up again and we can go and look in the outline 26 00:02:08,270 --> 00:02:11,870 ‫for our moving platform and select it. 27 00:02:11,870 --> 00:02:12,650 ‫And they go. 28 00:02:12,650 --> 00:02:19,310 ‫You can now see that the new property I'd added is not only there but it is also there with the value 29 00:02:19,310 --> 00:02:21,260 ‫that we saved it as before. 30 00:02:21,260 --> 00:02:25,670 ‫We close the editor for the first time so we've not lost any data this way. 31 00:02:25,670 --> 00:02:31,310 ‫Now I find that 90% of the problems with live coding boils down to this issue. 32 00:02:31,310 --> 00:02:37,130 ‫So if that's the case, then a restart of the editor and reloading can do the trick. 33 00:02:37,130 --> 00:02:43,520 ‫But if you find that frustrating or you seem to be having other issues with live coding, you can revert 34 00:02:43,520 --> 00:02:46,490 ‫to the old method of doing stuff which is called hot reloading. 35 00:02:46,490 --> 00:02:50,270 ‫You go to the edit menu and go to the editor preferences. 36 00:02:50,270 --> 00:02:56,810 ‫You select live coding under the general section and you just disable live coding like. 37 00:02:56,810 --> 00:03:04,040 ‫So then you can close the preferences and you'll need to restart the editor to make this change permanent. 38 00:03:04,040 --> 00:03:11,570 ‫So once that has been restarted, you can recompile either using the usual recompile button at the bottom, 39 00:03:11,570 --> 00:03:12,290 ‫right? 40 00:03:12,290 --> 00:03:18,230 ‫So hopefully this lecture will see you through any issues you may encounter compiling with live coding. 41 00:03:18,260 --> 00:03:19,970 ‫And I'll see you in the next lecture.
