WEBVTT 00:06.880 --> 00:08.170 Welcome back. 00:08.410 --> 00:15.610 Now we're saving our attributes, which is great, but our load screen menu doesn't show the correct 00:15.610 --> 00:16.210 level. 00:16.240 --> 00:18.940 Well, we never actually bound this to anything. 00:18.940 --> 00:24.820 We're going to need to bind it, which means we need a way to access that level. 00:24.850 --> 00:25.360 Right. 00:25.360 --> 00:28.540 So we're going to head back into C plus. 00:28.540 --> 00:38.560 Plus I'm going to close all tabs and let's go into public UI view model and get my load slot view model 00:38.560 --> 00:39.190 here. 00:39.760 --> 00:43.990 The load slot view model is going to want to know the player level. 00:43.990 --> 00:49.480 That's because we want it to be a field notify, just like player name and map name. 00:49.570 --> 00:51.820 And this can be an integer. 00:51.820 --> 00:55.960 So I'm going to copy map name with its u property and paste it. 00:55.960 --> 00:58.600 But this is going to be an int 32. 00:59.380 --> 01:01.900 And we'll call this player level. 01:03.010 --> 01:05.380 Now it needs a getter and setter. 01:05.380 --> 01:13.480 So we're going to make a void set player level which takes in an INT 32 called in level. 01:13.480 --> 01:20.680 And we're going to generate the definition and use the field notify broadcast macro. 01:20.680 --> 01:24.550 So you e MVVM set property value. 01:24.580 --> 01:32.620 We're going to use player level and broadcast in level like so. 01:32.620 --> 01:34.930 And then we can get a getter up here. 01:34.930 --> 01:37.780 So we're going to have an INT 32 returning function. 01:38.980 --> 01:45.700 Get player level const return player level. 01:47.680 --> 01:49.000 Okay, great. 01:49.000 --> 01:53.230 Well, this means we're going to need to actually set this. 01:53.230 --> 01:55.390 So where are we going to do that. 01:55.420 --> 01:59.290 Well let's go into our load screen view model. 02:00.760 --> 02:03.310 And when do we need to set this? 02:03.340 --> 02:10.540 Well, when we load data and when we save data, we now have to save our level along with our player 02:10.540 --> 02:11.050 name. 02:11.050 --> 02:12.760 Let's start with saving data. 02:12.760 --> 02:19.120 So we first save data when new slot button pressed is called we call set map name. 02:19.120 --> 02:20.770 We call set player name. 02:20.950 --> 02:24.010 Now we can also call set player level. 02:24.010 --> 02:29.050 So we're going to take load slots here of slot and call set player level. 02:29.050 --> 02:30.970 And this is for a new slot. 02:30.970 --> 02:33.490 So player level can be set to one here. 02:33.490 --> 02:36.340 Basically what its default value already was. 02:36.340 --> 02:38.110 Nothing really changes. 02:38.110 --> 02:42.010 Now when we call load data we need to load that player level. 02:42.010 --> 02:49.390 This happens at the very beginning and this is where we set our load slot, player name, slot status, 02:49.390 --> 02:50.350 map name. 02:50.350 --> 02:53.050 And we can set the load slots level as well. 02:53.050 --> 02:55.690 So we're going to take load slot dot value. 02:55.690 --> 02:58.000 And we're going to call set player level. 02:58.000 --> 03:00.100 Very important that we call the setter. 03:00.100 --> 03:02.290 We're going to get it from the save object. 03:02.500 --> 03:04.660 That's going to be player level. 03:04.660 --> 03:06.940 So now we're actually updating it. 03:06.940 --> 03:13.210 The last thing to do is to bind our widget's level text to that field notify. 03:13.210 --> 03:17.410 So I'm going to close the editor and launch backup. 03:17.410 --> 03:20.890 So back in the editor looks like I'm done with these two widgets. 03:20.890 --> 03:25.540 I need to get my load slot taken. 03:25.810 --> 03:29.890 And it's this widget here the little text. 03:29.890 --> 03:35.920 It's called text underscore level value I need this bound I need to check is variable. 03:35.920 --> 03:40.960 First I'm going to compile and then open my view bindings. 03:40.960 --> 03:42.670 And we're going to add a new one. 03:42.670 --> 03:44.380 We're going to click add widget. 03:44.470 --> 03:48.670 We're going to select text Level value. 03:49.810 --> 03:52.630 We're going to select its text. 03:52.630 --> 03:54.340 That's what we want to bind. 03:54.340 --> 03:56.590 We want one way to widget. 03:56.590 --> 03:59.710 And we're going to need a conversion function. 03:59.710 --> 04:02.290 We need two text from integer. 04:02.380 --> 04:05.680 So we're going to choose two text parentheses integer. 04:05.680 --> 04:10.930 Select that and here's the value we see always sign. 04:10.930 --> 04:13.480 If we check that it's going to have negatives. 04:13.480 --> 04:14.800 We don't care about negatives. 04:14.800 --> 04:16.510 We're going to leave that unchecked. 04:16.510 --> 04:22.780 The minimum number of integral digits is going to be one and the maximum 324. 04:22.810 --> 04:24.400 That's totally fine. 04:24.850 --> 04:27.580 But we do need to bind the value here. 04:28.210 --> 04:32.020 So if we click right here, bind this argument to a property. 04:32.050 --> 04:40.000 Now we can click on this choose load Slot View model and pick Player Level and hit select. 04:40.120 --> 04:43.420 And we're going to uncheck Use Grouping. 04:43.810 --> 04:49.750 Now due to the lack of documentation and the newness of this technology, it isn't clear to me what 04:49.750 --> 04:50.650 use grouping is. 04:50.650 --> 04:53.110 I just know that this doesn't work without it. 04:53.110 --> 04:54.610 So we're going to uncheck that. 04:54.610 --> 04:56.380 And with that we can press play. 04:56.380 --> 04:57.970 And we see level four. 04:57.970 --> 04:59.710 Now I can make a new game. 04:59.710 --> 05:04.810 Enter a name select the slot press play and level up. 05:07.130 --> 05:08.690 Now I'm level four. 05:08.720 --> 05:10.490 I can save the game. 05:11.260 --> 05:13.090 And exit and come back. 05:13.090 --> 05:14.680 And now it's level four. 05:14.680 --> 05:20.410 Now the only problem is if we never actually save the game and load back in. 05:20.410 --> 05:30.190 So if I create a new slot here and select it and play, and I never actually save anything and I exit 05:30.190 --> 05:32.440 and come back, now it's zero. 05:32.440 --> 05:35.140 Now this is actually a pretty easy fix. 05:35.140 --> 05:38.620 We don't have to go out of our way to make sure that that's a one. 05:38.620 --> 05:42.610 If we've never saved it, it should always be a one unless we've saved it. 05:42.610 --> 05:43.000 Right. 05:43.000 --> 05:46.930 So let's go to the game folder open load screen save game. 05:46.930 --> 05:49.780 And we'll just set this to a default value of one. 05:50.080 --> 05:54.850 We'll always have a player level of one unless we've actually saved the game. 05:54.850 --> 05:59.170 So pretty easy fix for that little edge case there. 05:59.170 --> 06:01.690 And with that we'll open the load menu. 06:01.690 --> 06:03.010 And it says one. 06:03.010 --> 06:06.610 Perfect okay I'm going to delete that slot. 06:06.610 --> 06:08.320 I'm going to delete this slot. 06:08.320 --> 06:11.020 And I'll go ahead and delete that slot. 06:11.020 --> 06:16.450 And we're ready to start thinking about how to save our abilities. 06:16.450 --> 06:18.100 And we'll do that next. 06:18.190 --> 06:19.390 I'll see you soon.
