🌐 Have you found the videos Helpful and Valuable?

[ggre]

i totally forgot about this i cant believe how easy it is, thank u.
i think i need to watch more videos about this topic

[petermarsh]

Your tutorials are so effective, well explained and, most importantly, straight to the point! No annoying waffle!
I've studied programming for 5 or so years now and have just picked up Unity, and you are helping me so much!
Keep it up :)

I have a computer science degree but I'm not ashamed to say that I still enjoy and benefit from watching your coding videos as they are so very practical and stress the importance of clean and reusable code!

Thank you for this!

Also if anyone wants the save file to not have the "_" on the first save time but have it if the save exists. For example it will save the first file as "save.txt" then any save after will be "save_1.txt", "save_2.txt", "save_3.txt" and so on Just use the following code as the Save function.

public static void Save(string saveString)
{
string theFirstSavePath = Path.Combine(Application.dataPath, "Save Folder", "save.txt");
string theFollowingSavesPath = Path.Combine(Application.dataPath, "Save Folder", "save_" + saveNumber + ".txt"));
int saveNumber = 1;
if ||
{
while (theFollowingSavesPath)
{
saveNumber++;
}
File.WriteAllText(theFollowingSavesPath), saveString);
}
else
{
File.WriteAllText(theFirstSavePath), saveString);
}
}

Very nice tutorial, I'm glad you made one on this topic

[bigbangpegasusmaster]

it's giving me an "Object reference not set to instance of an object" whenever I try to use any of the IUnit methods (and yes I do have something set for Unit)

[manuelillanes]

Hi, I don't know why but it never create a file, it can create a folder but it is always empty. I'm compiling for android, i don't know if that is what is causing the problems.

[unvisibleone]

Its so good but hard






Thanks

Cool tutorial very helpful. i was going to use binary but binary is unsafe when deserializing so yeah!

[herzogtwo]

if i import the utilities and this project unity say missing prefab and i have a black background

[yasserahmed]

That's why he is the GOAT, THE GOAT

[blablu]

The type or namespace name 'IUnit' could not be found (are you missing a using directive or an assembly reference?) Help me pls

[DanielAbeleira]

How would you extend this to more than just one object? I'm planning a city building game and I need to load the assets that the player placed where they were placed

[icyicecream]

How would you go about serializing sprites? Right now, when i save the sprite it writes an instance id for the sprite, but when i load it again it returns null. Thanks in advance

If I used json file as database to store something like player information(like player's name, level), and publish as apk 1.0.
After a moment, I had updated and added certain new information(now it have player's name, level, stat and win/lose records) to the same json file and publish as new apk 1.1,
Will the previous player information (name and level) lost and replaced by new and clean json file?
Or how should we remain the old data while we updating json files?

[ohj]

hi, why do you use a constant in your save system ? what's the point of doing that ?

[SaSeshen]

I have watched, and read several videos/tutorials on the Save and Load function, but they all discussed binaries as the primary mechanism, why would I want a JSON over Binaries or vice versa?

[The_Peprechaun]

What object is meant to be assigned to the 'Unit Game Object'?

[alecson]

Referencing from your Inventory video, Do I write the item.itemtype and item.amount into the SaveObject class? I'm trying to save the amount of the items that correspond to the itemtype. Pretty stuck on this for days trying to figure out how to accomplish this! Please help!
