How do you parse JSON files with std.json?

[MikeHartParticipant]

For fantomX2 I wanna use std.json to parse TileD map files. But I am puzzled who to do that. Can someone lend me a helping hand/code?

Looks like it works fairly similar to brl.json from MX1…  Data members of JsonObject appear to be directly accessible through operator overloading of [] though.  Using JsonObject.Load(path) should create the object.  Then, you basically either work with the JsonValues directly, or unbox them / bus them to your game’s variables.  Again sometimes in MX1 this required direct casting.  I don’t know if that situation’s changed now, but if you need to cast, remember that the syntax has changed for MX2 and is now a kinda weird looking operator thing Cast<T>(expression).

Edit:  Almost forgot.  TMX map format by default uses XML (gross), the json format is an “export” format for Tiled, although its structure is nearly identical to standard TMX, save for changes in the syntax and one or two other things…

Method Load() _name="dark" _fontSize=16 _monoFontSize=16 Local obj:=JsonObject.Load( "bin/ted2.config.json" ) If obj If obj.Contains( "theme" ) _name=obj["theme"].ToString() Endif If obj.Contains( "fontSize" ) _fontSize=obj["fontSize"].ToNumber() Endif If obj.Contains( "monoFontSize" ) _monoFontSize=obj["monoFontSize"].ToNumber() Endif Endif

Method Load() _name="dark" _fontSize=16 _monoFontSize=16 Local obj:=JsonObject.Load( "bin/ted2.config.json" ) If obj If obj.Contains( "theme" ) _name=obj["theme"].ToString() Endif If obj.Contains( "fontSize" ) _fontSize=obj["fontSize"].ToNumber() Endif If obj.Contains( "monoFontSize" ) _monoFontSize=obj["monoFontSize"].ToNumber() Endif Endif

this snippet is from theme.monkey2[20] and is how ted2 parses it’s config file

I consider ted2 one big monkey2 programming example / banana and study it often.

Thanks Simon. I mixed something up. I didn’t mean Tiled but spritesheets created by TexturePacker.

Anyway, thanks for the hint and example. That should get me started. I Have used a different JSON module before, but wanna got now “standard” and use the BRL implementation to get rid of one 3rd party dependency in my framework.

I’m having trouble with translating monkey1 code

Monkey

For Local it:map.Node<String, JsonValue> = Eachin JsonObject( jso.Get("data") ).GetData() Local oclass:JsonObject = JsonObject( it.Value ) If it.Key="player" Then

1 2 3 4 5

For Local it:map.Node<String, JsonValue> = Eachin JsonObject( jso.Get("data") ).GetData()     Local oclass:JsonObject = JsonObject( it.Value )     If it.Key="player" Then

But how to translate this to monkey2 ?

Monkey

' For Local data:Map.Node<String, JsonValue> = Eachin obj["data"].ToObject() ' For Local data:Map.Node<String, JsonValue> = Eachin obj["data"].ToObject().Data If data.Key = "player"

1 2 3

' For Local data:Map.Node<String, JsonValue> = Eachin obj["data"].ToObject() ' For Local data:Map.Node<String, JsonValue> = Eachin obj["data"].ToObject().Data      If data.Key = "player"

I know that this is working but I need both, the json KEY and Value

Monkey

For Local data:=Eachin obj["data"].ToObject() If data.Key = "player" ' but now I don't have the value

1 2 3

For Local data:=Eachin obj["data"].ToObject() If data.Key =  "player" ' but now I don't have the value

The json file is something like this
{
“w”:2048,
“h”:768,
“p”:200,
“data”:{
“world”:{
“atlas”:”atlas-world1.json”,
“data”:”data-world1.json”
},
“player”:{
“atlas”:”atlas-player.json”,
“data”:”data-player.json”,
“initFrameKey”:”looprechts”,
“initX”:300,
“initY”:712
}
}
}

Found the solution after trying

Monkey

For Local data:=Eachin obj["data"].ToObject() Local obj2:= data.Value.ToObject() If data.Key = "player"

1 2 3 4

For Local data:=Eachin obj["data"].ToObject()     Local obj2:= data.Value.ToObject()     If data.Key =  "player"
