#okay, for the sake of not making 1
spare cloak
okay, I will also include screnshots of the game of what I am modifying to provide additional clarity
dark wyvern
What is a "modified" tile? One where tileType is 1 or something?
What is the data we're looking for
spare cloak
This is the default grid, all tiles have tileType 1, which is the default
I have drawn red triangles, which are tileType 4
the game recognizes this and adds the modified tiles to tileHolder[x,y], where the x,y are the xy of the object affected
dark wyvern
alright and you save that to JSON at some point yes?
spare cloak
when I hit the "export" button, a json is created, and the entire array is gone through, with each object serialized to to a json.map file
I will post the json's contents if needed
spare cloak
now
dark wyvern
ok so on to the parsing part
spare cloak
when I hit load(same game instance)
we get an updated grid
(the shapes are different because I just wanted to see if would keep color and change stuff)
as you can see, the log posts the x,y and tiletype of all modded instances
dark wyvern
mhmm...
spare cloak
okay
now
I will close the game
and when I reopen and hit load
the X,Y is off... that's new
how is that possible? It literally loaded perfectly same game, is this a memory issue?
dark wyvern
Most likely an error in your logic somewhere
is this the same file you shared with me?
- double check the json file hasn't changed
- debug the "parsed" data to see which coordinates should be red
spare cloak
yes I literally opened it and checked it now
still 22 instances
the debug.log has the same amount of posts
dark wyvern
ok so after your parsing code - log the coordinates of the tiles that are 4
we want to see the coordinates\
spare cloak
it already does that
dark wyvern
I jsut see it logging 4
dark wyvern
those coordinates are clearly different from what's in the file
so I think it's likely a parsing issue
also why is it printing 2, 1 twice
and 3, 1 twice
spare cloak
ah because I wanted to show it pre and post towerStorage creation
the first is the parsed string, the 2nd is as a towerstorage object
that is now in the tileHolder array
dark wyvern
that is now in the tileHolder array
int x = int.Parse(subby[0].Substring(subby[0].Length-1));
int y = int.Parse(subby[1].Substring(subby[1].Length-1));
int tT = int.Parse(subby[2].Substring(subby[2].Length-1));
int tot = int.Parse(subby[3].Substring(subby[3].Length-1));```doesn't this logic assume that the number coordinate is only one digit?
spare cloak
oh, rats
dark wyvern
So {"x":12,"y":11,"tileType":4 will get parsed as 2, 1
so yeah - again - I implore you to use a real JSON parser lol
spare cloak
okay, yeah, that's my stupid mistake
dark wyvern
Although as it is your file is not actually legal json
spare cloak
Would I have to wrap my array as a class so that it can be pushed as an object into json.serialize object?
dark wyvern
if you want to use JsonUtility in unity you would basically do:
[Serializable]
public class TileData {
public TileStorage[] allTiles;
}
[Serializable]
class TileStorage
{
public int x;
public int y;
public int tileType;
public int towerType;
// etc.````then you just do this to parse it:
TileData data = JsonUtility.FromJson<TileData>(jsonString);```
And create the json with:
```cs
TileData data = // create this somehow in code
String json = JsonUtility.ToJson(data);```and the Json would be able to parse it perfectly and won't just leave me with a bunch of blank brackets?
dark wyvern
not sure what you mean by blank brackets, but yes the parser knows how to handle json perfectly
spare cloak
yeah, it's just that a previous issue when pusshing an array to json it just gave me a json of repeating {}{}{}{}
dark wyvern
yeah, it's just that a previous issue when pusshing an array to json it just gav...
that sounds like you didn't mark your class as [Serializable] or it didn't have any serializable fields
spare cloak
ah, I didn't know that was something I had to do
dark wyvern
ah, I didn't know that was something I had to do
also 2D arrays like this cannot be directly serialized
But yes Unity's serializer has rules that need to be followed https://docs.unity3d.com/6000.0/Documentation/Manual/script-serialization-rules.html
spare cloak
ah, so if I wrap it in a class will it be okay?
dark wyvern
ah, so if I wrap it in a class will it be okay?
no - 2d array can't be serialized at all
it neees to be flattened into a 1D array
dark wyvern
if you want to use JsonUtility in unity you would basically do:
```cs
[Serializa...
like in this example
spare cloak
ahhhhhh
dark wyvern
spare cloak
if there's a flatten is there an unflatten?
dark wyvern
it's easy enough to write one sure. But you don't need it in this case since each tile actually stores its own x/y it's just:
foreach (TileStorage ts in myTIleData.allTiles) {
tileHolder[ts.x, tx.y] = ts;
}```right but if i had to edit a specific tile, how would I go about accessing it through the array?
dark wyvern
There's no need to edit a specific tile until it's in your tileHolder array
this whole thing is JUST for reading and writing to the file
once it's in tileHolder you can do tileHolder[x, y] as normal
spare cloak
ahhh you're right
I can have it be a 2d array UNTIL I need it JUST for saving
in which case I'd flatten/unflatten
dark wyvern
TileData is just an intermediate format for serialization yes
dark wyvern
do I need to add a using for the [Serializeable]attribute?
using System;
but also it's spelled [Serializable]
oh wait you have the spelling right - yeah just using System
spare cloak
adding using System worked
dark wyvern
you need it on TileStorage as well btw
spare cloak
okay, added
so now for the save/load process, just convert tileHolder to tileData with flatten
then json serialize
then json deserialize, unflatten, and go
wow what i made was a massive waste of time
spare cloak
how do I make a tileStorage[] into a tiledata? Is there a way to convert or do I have to write a new method for it to convert?
dark wyvern
TileData td = new TileData {
allTiles = tiles
};```or just:
TileData td = new TileData();
td.allTiles = tiles;```it's not converting just assigning the array as the allTiles field
dark wyvern
I'm getting an error when converting back to TileData
how did you create the json
and can you show the file
dark wyvern
remember:
- flatten your 2D array
- shove it in a TileData
- call ToJson on the TileData
dark wyvern
yep the file looks good
dark wyvern
you're trying to parse the filepath
not the json data
string jsonString = File.ReadAllText(Path.Combine(path, "Map.json"));
you ned to read the file first^
spare cloak
ahhhh
dark wyvern
then TileData tiles = JsonUtiltiy.FromJson<TileData>(jsonString);
no need for creating the new empty one before that
dark wyvern
Nice
