WEBVTT 00:06.800 --> 00:07.790 Welcome back. 00:08.180 --> 00:14.870 Now that we have the ability to load in at the correct checkpoint, the last one we saved at and we're 00:14.870 --> 00:16.280 saving world state. 00:16.280 --> 00:21.560 So all checkpoints that have previously been reached are already reached. 00:21.560 --> 00:22.700 We can't reach them again. 00:22.700 --> 00:25.940 They're all glowy and that looks great. 00:25.970 --> 00:28.790 Now it's time to start saving player state. 00:28.820 --> 00:35.450 Now, I don't mean the player state class, I mean the state of all the variables pertaining to our 00:35.450 --> 00:44.120 player such as level attributes, attribute points, all of that great information that we can load 00:44.120 --> 00:44.810 in with. 00:44.840 --> 00:48.320 We're going to want to figure out how we can save all that. 00:48.320 --> 00:53.660 Well, if we're going to save anything, it needs to be in our save game object so we can start there. 00:54.580 --> 01:01.060 I'm going to go ahead and close all my tabs and just go into my save game object header file. 01:01.060 --> 01:04.930 That's going to be in game load screen save game. 01:05.380 --> 01:07.600 Now we called it load screen save game. 01:07.600 --> 01:10.150 But really we could have just called it Aura Save game. 01:10.150 --> 01:10.600 Right? 01:10.600 --> 01:16.300 Because it's going to contain all of the information that we're going to save. 01:16.480 --> 01:22.300 And all of this stuff at the top is kind of just necessary for a save game object. 01:22.300 --> 01:24.820 We have the slot name, the slot index. 01:24.820 --> 01:26.410 We have the player name. 01:26.980 --> 01:34.630 That pertains to the load screen and we have our map name, the player start tag, save slot status, 01:34.630 --> 01:37.300 and then the save actors for the world. 01:37.300 --> 01:41.740 Underneath this though, we can start having more player specific stuff. 01:41.740 --> 01:43.330 We're going to say player. 01:45.260 --> 01:48.830 We don't want to say player state because that sounds like the player state class. 01:48.830 --> 01:50.450 I'm just going to say player here. 01:50.930 --> 01:54.140 So what all do we need for our player? 01:54.140 --> 01:55.580 What do we need to save? 01:55.580 --> 02:00.890 Well, there are four variables that come to mind that exist on the player state. 02:01.280 --> 02:03.080 Those are the player level. 02:03.320 --> 02:06.350 Let's just go ahead and add these as we can think of them. 02:06.350 --> 02:09.380 That's an INT 32 called the player level. 02:10.040 --> 02:13.910 And we'll give these all default values I'll start them off at zero. 02:13.910 --> 02:16.010 But of course we're going to save them right. 02:16.010 --> 02:17.960 We're going to save and load them. 02:17.960 --> 02:20.570 So it doesn't really matter what we initialize them with. 02:20.570 --> 02:22.460 But there's player level. 02:22.670 --> 02:25.430 We're also going to want our XP. 02:26.210 --> 02:27.800 We'll just call that XP. 02:27.800 --> 02:32.240 And our player state also has spell points and attribute points. 02:32.240 --> 02:33.380 Let's do that too. 02:33.380 --> 02:38.150 We'll have spell points and we'll have attribute points. 02:39.680 --> 02:40.970 And in your game. 02:40.970 --> 02:46.190 If you have more things you need to save from your player state, you'd add them here too. 02:46.280 --> 02:47.210 Now. 02:48.120 --> 02:55.380 In addition to that, we have attributes and thanks to all of our attributes, except for primaries 02:55.380 --> 03:01.380 being derived from other attributes, all we need to save are the primaries, because if we set the 03:01.380 --> 03:07.800 primary attributes, the secondary attributes are all based on the primaries or each other, and the 03:07.800 --> 03:11.070 vital attributes are based on other attributes as well. 03:11.070 --> 03:13.650 So everything is derived from the primaries. 03:13.650 --> 03:20.220 So if we save the primary attributes we're set when it comes to attributes, at least in this project, 03:20.430 --> 03:24.000 if you had other attributes you needed to save, you'd save them too. 03:24.120 --> 03:25.980 So we're going to save these as floats. 03:25.980 --> 03:27.570 I'm going to start with strength. 03:28.170 --> 03:32.370 And these will all get defaults of zero and new properties. 03:32.370 --> 03:36.210 So there's a strength and we need four more. 03:36.210 --> 03:42.930 I'm just going to copy this and paste it four times one two actually three for a total of four. 03:42.930 --> 03:50.100 And we're going to have strength intelligence resilience and vigor. 03:51.900 --> 03:55.440 And with that we have our primary values. 03:55.440 --> 03:58.350 Now this is everything except for abilities. 03:58.350 --> 04:00.870 We'll do the abilities in a future video. 04:00.870 --> 04:04.650 For now, let's just get these basic numerical values. 04:04.650 --> 04:06.870 We want to be able to save these. 04:07.290 --> 04:09.210 So how are we going to save them? 04:09.690 --> 04:16.110 Well, first of all, before we answer that question, we should ask ourselves where in the code should 04:16.110 --> 04:17.070 we save them? 04:17.760 --> 04:21.240 Well, we should save them in our interface function. 04:21.240 --> 04:22.530 Save progress. 04:22.530 --> 04:23.100 Right. 04:23.100 --> 04:30.990 Let's go into character and we'll just go straight to the private folder character or a character we 04:30.990 --> 04:32.130 have save progress. 04:32.130 --> 04:38.340 This is where we're saving the checkpoint tag that's passed in here, because this is called from a 04:38.340 --> 04:39.330 checkpoint. 04:39.510 --> 04:46.410 And while we're saving that player start tag the checkpoint tag, we can save all the other pertinent 04:46.410 --> 04:50.130 data that we need to save right here in save progress. 04:50.580 --> 04:52.590 That's what we need to do. 04:52.590 --> 04:56.190 So four of those variables are on the player state. 04:56.190 --> 04:58.380 So we need to access the player state. 04:58.380 --> 05:00.450 So let's get the player state here. 05:00.450 --> 05:04.800 We're going to say a or a player state. 05:07.280 --> 05:15.320 Or a player state equals a cast to A or a player state. 05:17.710 --> 05:19.750 And we're going to call get Player state. 05:22.870 --> 05:25.270 We can wrap this in an if statement. 05:27.270 --> 05:33.360 And we can start saving those four variables on the player state to our save data. 05:34.800 --> 05:36.660 So we're going to take save data. 05:36.660 --> 05:40.170 And let's just start with player level. 05:41.070 --> 05:48.030 We're going to get our player state and call get player level. 05:50.530 --> 05:53.410 And we'll do this three more times. 05:53.410 --> 05:53.890 One. 05:53.890 --> 05:55.300 Two, three. 05:55.330 --> 06:00.160 Only we're going to change what we're setting here instead of player level. 06:00.160 --> 06:06.190 We're going to have what's the next one XP and we'll call get XP. 06:08.870 --> 06:11.210 We also have attribute points. 06:12.420 --> 06:13.620 Let's call. 06:14.290 --> 06:18.130 Get attribute points and we have spell points. 06:18.880 --> 06:21.970 We'll call get spell points. 06:23.930 --> 06:28.730 And now our save data is going to contain those four variables. 06:29.150 --> 06:30.170 Okay. 06:30.200 --> 06:34.520 Now we also have to save our primary attributes. 06:34.850 --> 06:37.880 Well how are we going to get our primary attributes. 06:37.910 --> 06:41.480 Well we have you ora attribute set. 06:42.380 --> 06:48.110 And we have get strength attribute which is static. 06:48.110 --> 06:51.650 And from this we can get numeric value. 06:52.220 --> 06:55.490 Now get numeric value requires an attribute set. 06:55.490 --> 06:59.810 But or a character has a get attribute set function. 06:59.810 --> 07:01.010 We made that. 07:01.010 --> 07:02.690 That makes it easy right? 07:02.870 --> 07:05.420 So this gives us the strength attribute. 07:05.840 --> 07:08.210 We can save that and our save data. 07:08.210 --> 07:13.490 We can take save data strength and set it equal to this. 07:14.570 --> 07:16.910 And we'll do the same thing for the other attributes. 07:16.910 --> 07:18.380 Let's take save data. 07:18.650 --> 07:20.510 We'll do intelligence next. 07:22.360 --> 07:29.020 And I'm going to copy this line and change this to get intelligence attribute. 07:30.220 --> 07:32.140 Let's do our next one. 07:32.470 --> 07:39.520 We'll do Resilience control V and change this to get resilience attribute. 07:39.520 --> 07:43.660 And one more save data Vigor. 07:45.400 --> 07:48.550 And we'll paste and use get vigor attribute. 07:48.550 --> 07:54.760 So now our save data has these four values from the player state and these four values from our attribute 07:54.760 --> 07:55.480 set. 07:56.320 --> 08:00.280 And our load screen save game just has those eight values. 08:00.280 --> 08:04.090 And I'll go ahead and give this a comment that says attributes. 08:06.370 --> 08:09.430 So with that, we're saving our progress. 08:09.430 --> 08:09.730 Now. 08:09.730 --> 08:11.950 How do we load our progress? 08:11.950 --> 08:14.920 How do we set these when loading in? 08:14.920 --> 08:17.740 Well that's a little bit more involved. 08:17.740 --> 08:20.440 And we're going to do that in the next video. 08:20.440 --> 08:22.000 So excellent job. 08:22.000 --> 08:24.130 Let's go ahead and just quickly compile. 08:24.130 --> 08:27.520 Make sure we didn't do any terrible things. 08:27.700 --> 08:28.990 Looks like we're good. 08:28.990 --> 08:33.280 And in the next video we'll load our progress I'll see you soon.
