0:00hello everyone and welcome back to a new
0:02video on the how to make a bit Simulator
0:04Xbox game series in this video I'm going
0:07to be showing you how to save the areas
0:09that we bought and the player stats and
0:12the players coins and gems
0:14also if you guys want to support me and
0:17want to have access to all of the
0:18project files including the one you're
0:20watching right now they will all be
0:21available on my patreon in Nintendo all
0:24tier
0:24so when recording this video I realized
0:27that I did not show the INF the
0:28interface of creating attributes
0:31so here's how attributes work when you
0:33create so here's my instance I have a
0:36part selected if I scroll down and click
0:39add attribute it will say tell me to
0:41give my attribute name so for example
0:44test
0:45and it will give me it will tell me to
0:48select the type so string or Boolean I'm
0:52just going to say Boolean and if I press
0:54save your attribute should pop up here
0:56okay so the first thing I'm gonna do is
1:00go to server script service and I'm
1:02going to create a new script and I'm
1:03going to call it data save
1:06now I'm going to
1:09remove the print hello world I'm going
1:12to get some services so local players is
1:15equal to game come on get service
1:16players
1:19and then we need data source service
1:21silicon data store
1:24service is equal to game come on get
1:27service data source service and then I'm
1:30going to create a reference to server
1:33storage so local server or maybe
1:35actually we don't really need that
1:37I think I'm just going to create a data
1:41source local data store is equal to
1:44data store service go and get data store
1:48and I'm just going to give it a key so
1:51create the random key for me I'm just
1:53going to say
1:55um
1:56my data store Key
2:00and in here we are going to get the
2:02player data so we'll call player data is
2:05equal to
2:06and I think we have the folder inside of
2:10the main server script but I think what
2:12I'm going to do is just drag it inside
2:14of the data saver and that should work
2:17so local player data is equal to script
2:20dot player data
2:22and what I'm going to do to prevent this
2:24from erroring is I'm going to enter the
2:27main server script and in here I'm going
2:31to just comment this out or maybe just
2:33delete it
2:35but I think I'm just going to comment it
2:38so
2:40toggle comment
2:42and I'm going to go back to my data
2:44saver so
2:46blurry data and I'm going to create a
2:48function for save data so we'll call
2:50function save data
2:52and that's of course going to take the
2:53player as the first argument and another
2:56function for load data so local
2:59function and I think I'm going to call
3:01it load data so load data and that's
3:05also going to take the player
3:07and then I'm going to have a function
3:11layer removing so layer
3:14removing
3:17and that's also going to take the player
3:20and then I'm going to
3:23create the events so players.player
3:26added come on connect function load data
3:29so whenever a new player is added we're
3:31going to call the load data function and
3:33whenever a new player left so whenever
3:38layer removing so whenever a player
3:40leaves the game come on connect we're
3:42gonna call the player removing function
3:46okay so after calling those two
3:49functions sometimes when you are the
3:52last player in the server and you leave
3:55the game the server might shut down
3:57before you your data gets saved so what
4:01I'm gonna do is game common bind to
4:03close function
4:08and what I'm gonna do is Loop through
4:10every single player in the game so for
4:11underscore comma player in pairs uh
4:15players
4:16go and get going gets players
4:19I'm going against players
4:21dude
4:23I think I added an extra parenthesis
4:26now this gets cold whenever you shut
4:29down little servers or just something
4:30like that happens
4:32then we're gonna call that function and
4:34quarantine don't wrap
4:37uh save data
4:40player
4:43and after doing that what I'm gonna do
4:45is inside of the player moving function
4:48I'm going to call the save data function
4:51so save data player so whenever a player
4:53leaves the game we are calling the
4:56play removing function and we are going
4:58to call the save data function
5:02now after doing that what I'm going to
5:04do is
5:06go back to my saved data function and in
5:10here I'm going to create a table so a
5:12table called the data
5:14and inside of that data table
5:16it actually it's going to be empty and
5:19I'm going to Loop through every single
5:20folder in the player so for underscore
5:23comma folder in pairs player go and get
5:27children
5:30do
5:31and what I'm gonna do is check if player
5:35data
5:37go and finds first child
5:39folder.name
5:42then so what what we're doing here is
5:45basically just checking if the
5:48blur data folder has a has a this folder
5:52inside of it so if it does then what
5:54we're going to do is
5:56check
5:58if player data if the folder from the
6:01player data
6:03has this attribute called save children
6:06and is equal equal to true so
6:10what I'm going to do is okay I'm gonna
6:13explain what this does so
6:15if any of these folders have this
6:18attribute called save children
6:21if it's true then we are going to save
6:23everything that's inside of that folder
6:26if it is false then we're not going to
6:27do that so for example for our pets
6:30folder I'm going to add an attribute and
6:32it's going to be a Boolean and I'm going
6:34to call it save children
6:38now I do want
6:41the children from the past folder to be
6:43saved so all of our pets will be saved
6:45so I'm gonna do that and then after
6:49doing that I'm going to go back to the
6:50script
6:52and what I'm gonna do
6:54is
6:56so data
6:58folder.name
7:01is equal to an empty table so we are
7:03creating another table inside of that
7:04table
7:06and what I'm gonna do is check
7:10if blur data folder.name calling
7:14attributes save children values so
7:18if that folder
7:20if you want to save the values of the
7:22children inside of a certain folder for
7:24example our leader stats so we want we
7:28want it to save the coins and gems but
7:30we also wanted to save the children
7:32values so what I'm going to do is just
7:35go to my leader stats and I'm going to
7:37add an attribute and it's going to be
7:41a
7:42Boolean again and save children values
7:49now I'm going to make sure that this is
7:51checked
7:52because we do want to save our coins and
7:54gems and let's say you have a currency
7:56that you don't want to save actually
7:58we're going to get to that later
8:00so now what I'm going to do is for
8:03underscore commit child
8:05in pairs
8:07folder call and get children
8:11do
8:12so we are looping through all the
8:14children inside of that folder that I'm
8:17gonna check if not
8:20a child can get attribute
8:25do not do not save value then
8:31so maybe you won't
8:33some values to save but some values do
8:36not save so for example I want my
8:41sensitive values value to not save then
8:43I'm going to add a
8:45string value
8:47and I'm going a string attribute and I'm
8:50going to call it do not save value
8:53however we don't the uh
8:57this is only going to work if the values
9:01folder
9:02has the Boolean called save children
9:07and it's set to true so
9:09we're going to save all the children
9:11inside of the folder so if this happens
9:13we are going to save all the children in
9:16the folder
9:17but We're Not Gonna Save the value of
9:20this sent to value
9:22because it has this attribute called do
9:24not save value
9:26and
9:27this is also only going to work if we
9:30also have these save
9:33children values
9:37and it's going to be a Boolean again so
9:39if we want to save the children values
9:40we're going to do that and we also go
9:42and we are also going to save the
9:45children
9:46but we're not going to save the
9:49value of the sent to Value so I'm going
9:52to get rid of this I want this both of
9:54these to be false and I'm also going to
9:56remove this attribute
9:58now what I'm going to do is table don't
10:01insert so table dot insert and data
10:07square brackets folder.name
10:10oh no
10:12a table child dot name
10:16child.name comma child dot value
10:21comma child dot class name
10:26okay so we are saving we are adding a
10:33a table inside of the
10:36table that we just added so this table
10:38right here we are adding another table
10:40inside of it and that table will contain
10:43uh the properties of the child so the
10:47child name the child value
10:50and the child class name now I'll we're
10:54gonna see why this is useful why why
10:56we're gonna use the class name later
10:58so what I'm going to do after that in
11:01here I'm just going to
11:05put an else right here
11:07so if we
11:10don't have the safe children values
11:15then what I'm gonna do is
11:18we're gonna do that again so for
11:20underscore come a child in pairs let's
11:23go and get children do
11:27and what we're going to do is again
11:28check if it doesn't have the do not save
11:31value string
11:35or attributes and what we're gonna do
11:37this time is just
11:39Tableau insert data square brackets
11:42folder.name and child.name and
11:45child.class name so we are not saving
11:47the value so if we we are saving the
11:50children values then we are going to add
11:52the value of the child to the table if
11:55we are not doing that then well we're
11:58not going to save the child value we're
11:59only saving the child name and the child
12:03class name this is getting kind of
12:04confusing for me to explain and I'm
12:07really bad at explaining so sorry about
12:09that
12:10now what I'm going to do is after this
12:13big for Loop right here
12:15I'm going to go down and local success
12:19comma error MSG so error message is
12:22equal to P call function
12:25and data store
12:27so the data server that we created right
12:29here going save async so we are saving
12:33the data
12:34con save set async sorry
12:37uh player don't user ID
12:41comma actually sorry about user ID dot
12:44dot
12:45B
12:46now if you want a key for this
12:50I want to add it it's optional but I do
12:53want to have a key
12:55and we are going to save the data table
12:57so
12:59they don't
13:01now what I'm gonna do is check if
13:03success then
13:06and we're gonna print
13:08uh saved data
13:12else
13:15we are going to warn
13:17the ER MSG now what this is doing is
13:22basically
13:23if saving the data was a success then we
13:26are going to well print save data if
13:29it's not then it's not going to error
13:31this and break the whole script it's
13:33just going to warn us that it didn't
13:35work and it's going to tell us what we
13:36did wrong
13:38now what I'm going to do is go back I'm
13:40going to go to the load data function
13:43and what I'm going to do is Loop through
13:46so for underscore comma V in pairs
13:50layer data call and get children
13:53to do and we are going to take every
13:56single folder and value inside of the
13:58player data and
14:00clone it and parent it to the player so
14:03the colon clone the parent is equal to
14:06player so we are cloning it then
14:08parenting it to deep player
14:10after that local data
14:13this is just going to be in a uh this is
14:16going to be set to nil
14:18so again local success comma error MSG
14:24is equal to pical function
14:27and data is equal to and data store
14:31can get async this time not set async
14:34get a sync player.user ID
14:38dot dot key
14:40comma actually we don't need the comma
14:43so what what we are doing in here is
14:46setting a sync and then here we're going
14:48to get the data that we saved so as you
14:50can see in here we save the data and the
14:53key that we gave it is the
14:54player.userid.key
14:57and in here we have an empty variable
14:59called Data it's set to nil and
15:02here we are setting that data to the
15:06data that we saved earlier
15:08now again we are doing the the P call
15:10for the same
15:12reason so that it does not error and
15:15break the entire script now what I'm
15:16going to do is check if error MSG then
15:20so if it errors then we are going to
15:23kick the player so player come on kick
15:26and we are just going to say uh couldn't
15:31save data
15:36couldn't save that I will just okay
15:38could not
15:39save data
15:41now the reason why we are kicking the
15:43player is so that for example the player
15:45is going to so the player already played
15:48the game and grinded and got a thousand
15:50coins
15:52so if he leaves the game and rejoins and
15:55those thousand coins weren't able to
15:58load if he plays the game and leaves
16:02again
16:03it's going to save zero coins so if we
16:06could not load the data then we are just
16:08going to kick the player
16:10but before we do that I'm also going to
16:12warn the error message
16:15okay so after that I'm gonna check if
16:18the data
16:20is equal to something so if data then
16:23and I'm going to live through the data
16:25do
16:27and I'm going to check if hashtag V
16:32is greater than zero
16:34then
16:35what we're going to do is for X comma C
16:40now I'll explain what this does later in
16:42pairs
16:44V
16:45do
16:47and what we're going to do is check if
16:50player
16:51do strings I can't find first child C
16:55square brackets one
16:58now this is going to be hard for me to
17:00explain so I'm just going to do that
17:02later
17:04so if if that then we're gonna do this
17:09else we are going to create a new value
17:13so local value
17:16is equal to
17:17instance.new and it's going to be to
17:21string
17:22uh C square brackets three
17:25by the way this is the class name that
17:27we just saved
17:28and value dot name is equal to
17:33C square brackets one
17:35and value dot value is equal to C square
17:41brackets two
17:43and value dot parent
17:46is equal to player
17:49square brackets to string I
17:52okay so now it's time for me to explain
17:54what this does
17:56now
17:58if V is greater than zero this is
18:00basically the folder inside of the data
18:02because if you remember inside of each
18:04inside of the data table
18:07we created a folder
18:09a table for the folder that we saved and
18:13basically V in here means the folder
18:16that we saved so we gotta check in if
18:19how how much stuff is in the folder is
18:22greater than zero so if it's so if there
18:25is nothing in the folder then we're not
18:26gonna do anything we're not going to do
18:28all of this but if there is then
18:31we are doing from X for X comma C now X
18:35is the index
18:37I renamed it to X because I is already
18:40used here
18:42and C
18:44is basically
18:47the okay so C
18:50is this
18:53it's this table that we saved in here
18:56I don't know if this makes sense but so
18:58seize the value that we saved
19:01so C1
19:03is
19:05the values name so child.name
19:08and C2
19:11is the child's value so child.value
19:16and in here
19:18when we are creating the value C3 is of
19:24course the class name
19:25and C1 is the name and C2 is the value
19:29and to string I is basically
19:34the name of the folder okay so now I'm
19:37going to test this out and see if it
19:39works
19:40so what I'm gonna do is
19:44so we want to save the pets
19:47and the leader stats values
19:51I'm also going to have the save children
19:56dual value so save children Boolean
20:00true
20:03okay so now I'm going to see if this
20:05works
20:07so before testing this out into On
20:09Studio we're gonna go to game settings
20:11and security
20:14and enable Studio access to API services
20:18now if you play the game
20:21that should hopefully work
20:24so we have 1500 coins and a thousand
20:27gems I'm going to get a pet
20:32so I'm just going to Hash this pet
20:37and I'm going to change my coins and
20:41gems value
20:43so coins will be maybe
20:471123 and for the gems I'll have it set
20:50to 542.
20:55so remember these two values now I'm
20:57going to leave the game
20:58and see if this works
21:01so sprinted saves the data now we are
21:04going to see if it will load the data
21:09Okay so
21:10it couldn't load the data so we are
21:13going to check why this is happening
21:16okay so I found the fix all I did is
21:20check if C square brackets 3 is equal
21:23equal to nil then value is equal to
21:25instance dot Nu to string C2
21:28else the value is equal to instance dot
21:31Nu two strings C3 now the reason why is
21:35because if we don't have these save
21:37children values attributes set to true
21:40then C3 is not a thing because there is
21:43nothing in the third index
21:47so I basically just checked
21:50if C3 is equal equal to new then C2 if
21:54not then C3
21:56so this I think works so if I join the
22:00game
22:01I should have a cat saved
22:05and if I just go ahead and modify my
22:08coins and gems values so liter sounds
22:10coins and gems coins 323
22:14coins uh okay so coins
22:18for 400
22:21and 64.
22:26and then I'm going to stop the game
22:30and play it again
22:32and it should save everything so as you
22:35can see I have 464 coins and 323 gems
22:39okay so I just found a bug with the
22:42system so if you have you hatched for
22:45example two cats it will only load one
22:48cat and the reason why is because in
22:50here we are checking if the value is
22:52already there then we are just updating
22:54its value so what I'm going to do is
22:56just get rid of these three lines of
22:58codes right here and get rid of the end
23:01in here and I'm going to go to format
23:03format document and now everything
23:05should work just fine so I'm going to
23:07play the game
23:12and I'm just going to hatch two cards so
23:16here's the first one
23:18I'm gonna wait for this animation to
23:20play and I'm gonna hatch the second one
23:23okay so now I have two cats and a
23:26thousand four hundred four hundred and
23:27eighty coins and I'm going to leave and
23:30rejoin
23:35and now we have a thousand for 480 coins
23:38and we also have two cats
23:41now what I'm going to do is show you how
23:43to load the cats into your inventory
23:48so just enter the x-client local script
23:52so just go to star player scripts and
23:54enter X client and I'm just going to
23:58Loop through so for underscore some of
24:00the in pairs player top Pets Come and
24:04Get children
24:06do and create template the dot name
24:12and I'm also just going to
24:16wrap this in accordance so quarantine
24:2314 dot wrap
24:26and it's just going to take the function
24:29so create templates comma V Dot name
24:34okay so just do this and also make sure
24:36to add a weight in here so it has to
24:38wait five seconds and if you play the
24:40game now
24:41we should have two cats and two cats
24:45loaded onto our inventory so if I wait a
24:47bit
24:48they should load and now we can equip
24:50them oh we can't equip them
24:53okay that's a problem we're gonna have
24:55to fix
24:57okay so it says attempt to index nil
25:01with concleral children so
25:05I'm gonna go ahead and try to fix that
25:07okay so I just found out why and it was
25:10very simple just
25:13copy this
25:16copy these lines of codes of codes right
25:18here that we commented and go back to
25:21our data save script and just
25:24face them here
25:26and remove the
25:28comment so this local folder is equal to
25:32that and Dot parents is equal to
25:33workspace dot main folder
25:35unscoreworkspace.playerpets
25:37and that should work now if I play the
25:40game I should
25:41be able to equip my pets
25:46I'm just going to open up the pets
25:48inventory and I'm going to equip a path
25:50and as you can see it works and both of
25:52them should work
25:54okay so they both work
25:56now what I'm going to do is show you how
25:58to save the areas so if I go to my areas
26:00I added a an attribute safe children and
26:04Etc true
26:05but if you play the game
26:11there is itself says purchase
26:16and we still have to buy it
26:20so I'm gonna show you okay so uh
26:24it did save it now I'm going to leave
26:26the game
26:27rejoin
26:33and we do have the area that we just
26:36bought but if I go here
26:38then nothing happens so it says interact
26:42so what I'm gonna do is
26:47in the main server script we're gonna go
26:49down and whenever we
26:51want to purchase a door instead of doing
26:53this all we have to do
26:55is check if player so
27:00we need a way to get the player so what
27:03I'm going to do is just go back here and
27:07create a blur added event in here
27:14and I'm just going to delete this
27:17and what I'm gonna do
27:20is just check
27:23if player okay
27:28I'm going to Loop through every single
27:30door
27:33and what I'm gonna do is check if layer
27:37on the areas no areas gonna find first
27:42child
27:44door.name I'm gonna go back and see if
27:48okay so area one that should work
27:51door.name then
27:53I'm just going to fire a remote event so
27:57remotes
27:58we should have a purchase door
28:03remote function
28:06so
28:08I'm gonna see how this works so in here
28:11when we purchase the door
28:13where is it
28:15Bridges doorcon fire client okay all I'm
28:18gonna do is I'm going to
28:20add the remote event and I'm going to
28:22call it destroy door
28:24or remove
28:26door so
28:28remotes
28:31replica okay replicator storage
28:35where is it
28:38replicated storage so again the
28:41replicated storage spot remotes
28:43dot remove door calling fire client and
28:46it's going to take the player
28:48and what I'm going to do is go back to
28:50my main client script and right here
28:53where it says
28:54okay so I'm gonna go here I'm gonna do
28:56remotes Dot
29:00purchase door or don't remove the door
29:04the online event called connect function
29:08and I'm just going to do
29:11take the door
29:13door on Destroy
29:16now I'm going to go back to my main
29:18server and I forgot to send the door
29:20itself
29:21okay so now this should work
29:24if you play the game and you own a door
29:25it should destroy itself
29:31oh I forgot to do something
29:34we have to wait a couple of seconds
29:36before doing that
29:44maybe five seconds
29:49so if I join the game
29:50after a couple of seconds
29:53the door gets destroyed and I can go
29:55through it without having to buy the
29:57door again
29:58okay so I think this is going to be it
30:00for today's tutorial if this helped make

30:04it with your friends and I'll see you
30:05all in the next video bye
