great tutorial! personally, i used setasync() instead of updateasync() because of updateasync being slower and sending more api requests. to anyone reading this, keep this in mind!

can you implement a saving system into the placement system? it would really be helpful because i'm making a game kind of like mini cities. everything works I just need it to save but I don't know how to do it. if you had time to implement a saving system kind of like this but works with the placement system series you made, it would be awesome. thanks
aha, thank you, this is very well explained. I think im missing some context: am i right in thinking that this solution would be useful when making a placement system (of parts)? right now however, the relevant parts are in the datahandler... would i be correct thinking that 1. this is the place a placement system would save parts to? (which then are saved to the datastore when a player leaves) 2. if you wanted parts to not be linked to a player so much as to a server, then the starting signal shouldn't be playeradded but server startup (if that is something that exists)? I have read quite a lot and watched videos on datastores, but not proficient yet, please excuse me if im not getting things right. thank you for your response in advance
why do you need to put in the x y z seperately? cant we do obj.CFrame.Position instead of obj.CFrame.Position.X obj.CFrame.Position.Y obj.CFrame.Position.Z?
i get error: DataStoreService: CantStoreValue: Cannot store Array in data store. Data stores can only accept valid UTF-8 characters. API: UpdateAsync, Data Store: SBGObjectsData
Awesome! Is there away to save gui data. Like if someone wanted to mute music in the game and they go to the settings to turn it off then once they leave it saves it and when they join the music is muted.
You can save a boolean so True or False then retrieve that data when they join and if its True then enable the music, if its False then disable it. (Once player clicks music setting button fire an remote event to change the value in datastore, just make sure the arguments are Boolean so you just pass in True or False when firing.)
how can you save the brickcolor? i've tried many ways but it keeps on putting in the wrong type of color to each part. Could u please help me out? Please respond asap.
may you tell me how do you run it by a gui like save button? if you press the button it will save your parts, also for the load button too and make multiple buttons for other buildings and different stuff
IS this possible with gui objects in a tag? Because i want to save the visibility of the gui object, in my case a button and a text label. But how can i achieve that?
hey mate! Im a little nooby dev, wanted to ask how to save the position of a model inside a limited position like ex: a restaurant tycoon you place stuff and you save it bt there are dif spots and want them to spawn like you want to
Do you mean saving positions relative to a plot? If so, what you can do is utilize the CFrame library to convert your positions to local space (aka object space). You can use the Inverse() method to convert the CFrame: for i, item in ipairs(plot.itemHolder:GetChildren()) do -- Get 'local' positions and rotation local objCFrame = plotCFrame:Inverse()*item.PrimaryPart.CFrame local _, angle = objCFrame:ToOrientation() -- Add values to table table.insert(data, { tostring(item), objCFrame.X, objCFrame.Y, objCFrame.Z, math.round(angle*(180/math.pi)) }) end That will save the data relative to the plot chosen. To load in, you can reverse the process by simply multiplying the plot CFrame and the objects CFrame to convert back to world coordinates: for i, item in ipairs(savedData) do local newItem = items:FindFirstChild(item[1]):Clone() if newItem then local x = item[2] local y = item[3] local z = item[4] local yAngle = item[5]*math.pi/180 local angle = CFrame.fromEulerAnglesXYZ(0, yAngle, 0) local pos = plotCFrame*CFrame.new(x, y, z) newItem:PivotTo(pos*angle) end newItem.Parent = ITEM_LOCATION end This code won't work and is untested but that's the concept. Here are some more resources on the topic: create.roblox.com/docs/reference/engine/datatypes/CFrame#Inverse create.roblox.com/docs/building-and-visuals/studio-modeling/object-world-space create.roblox.com/docs/reference/engine/datatypes/CFrame#ToObjectSpace create.roblox.com/docs/reference/engine/datatypes/CFrame#ToWorldSpace You can also take a look at a video I made on this topic: th-cam.com/video/F413drdadDs/w-d-xo.html
Look for the IntValue 90 or the number in the CFrame in the rotate function and change it to 45 degrees :) assuming you used his plot system. Good luck c You could very much easily alter his code to do this simply. With little coding knowledge at all.
A better way would be to use a Enum key code like R to rotate and to display this as a icon and also use that same icon for mobile players to rotate hope this made sense What I mean is use the same code for the mobile button but change the function and the trigger for mobile inputs
For any object, assuming you want to reconstruct it, you just take the components you want to save and add them into a table. In your case, if you're just needing to save a value of the GUI's visibility, you can actually just save either the Enabled property on the ScreenGui or the Visible property on the frame that contains the UI elements since they are a boolean value.
unless you are storing thousands of parts per object, you should be fine. If you do run into issues relating to the data limit, you will need to look into data compression.
Yes, what I did was equivalent to using math.rad(). The reason I didn't use it was to show exactly what was going on. But yes, you are correct, you can simply use math.rad().
For tycoons what I recommend doing is simply looping through the objects on the tycoon, save the models position using GetPivot() (or by using the primary part position), then save the model name. When the player rejoins, you can use the name to access the model, and use the PivotTo() method to place it on the plot using the saved values.

To save every part within a model, you'd have to use the process shown in this video but on every object within a model. You can use GetDescendants() to run through all the parts in a model, save their components, and then load when needed.

great tutorial! personally, i used setasync() instead of updateasync() because of updateasync being slower and sending more api requests.
to anyone reading this, keep this in mind!
I've personally never head of updateasync lol
Me too used a long time ago SetAsync... Some players lost they Data. With UpdateAsync no one isn't lost Data
I was really confused on how to save non values to datastores, thank you so much!
I was thinking this would take like 300 lines of code.. you saved my game thank you

a great sequal to the placement series
Greatly explained, easy to understand!
Man u are so underrated I am in love with ur tutorials
Thank you so much! This is exactly what i needed for my game!
I recently came up with an idea for a tycoon sort of game and needed this to save what the player bought.
FINNALY THANK YOUU
I’ve been doing this the long way around for too long… 😒 Thank you for the lesson!!
Glad I could help you out!
The tutorial was really useful, thanks alot! Also, a type checking tutorial would be of great help!
You should go more in-depth with the placement system and this and make some form of housing system with a UI and such
This is an incredibly useful video, thanks!

local z = item[4]
local yAngle = item[5]*math.pi/180
local angle = CFrame.fromEulerAnglesXYZ(0, yAngle, 0)
local pos = plotCFrame*CFrame.new(x, y, z)
newItem:PivotTo(pos*angle)
end
newItem.Parent = ITEM_LOCATION

What if the part has a script inside?
didn't work : ( like there are error everywhere in the script. I wish i could just copy and paste it so that it maybe don't have the errors
Could you do a part 11 of the placement system tutorial that shows us how to implement horizontal placement?
Look for the IntValue 90 or the number in the CFrame in the rotate function and change it to 45 degrees :) assuming you used his plot system. Good luck c
You could very much easily alter his code to do this simply.
With little coding knowledge at all.
A better way would be to use a Enum key code like R to rotate and to display this as a icon and also use that same icon for mobile players to rotate hope this made sense

yo could we see the whole script?
is there any way you could save value's and then load the value in the same numbervalue?
how can i do this but with gui? for example i want my gui to become invisible and when the player rejoins its still invisible?

I need to get the color(hsv) from a mesh part. How do I get the hue sat and Val?
there is a problem with the first script when ever i typed in "load" "save" it underlined it in red, i don't think the script works any more
It always works, try checking for any mistakes.
hello, how can i save objects with scripts and other stuffs
what if the object has too many parts? a datastore key can only have 4 mb of data.
unless you are storing thousands of parts per object, you should be fine. If you do run into issues relating to the data limit, you will need to look into data compression.
a lot of yapping and code doesnt make sense sometimes.
Hello, i have 1 problem idk if its just for me, but it did not save the size?
you never saved the size, I think it's quite easy to understand how to add size saving
Do you by any chance know how to do this with vehicles?
You can only make create the position and orientation value of vehicles and then save them, if needed you can do more.
