Just for other people that working with json files.
The parse order is not the same as the file.

{
 "w":2048,
 "h":768,
 "p":200,
 "data":{
 	"world":{
 		"z":1,
 		"atlas":"atlas-scene1.json"
 	},
 	"player":{
 		"z":2,
	 	"atlas":"atlas-lopen.json",
	 	"initFrameKey":"looprechts",
	 	"initX":800,
	 	"initY":712
 	}
 }
}

Local jso:JsonObject = New JsonObject(str)
For Local it:map.Node<String, JsonValue> = Eachin JsonObject( jso.Get("data") ).GetData()
Print it.Key
Next

Output:
player
world

k.o.g.

Thats the functionality of Stringmaps..:

Strict

Function Main:Int()
	Local list:StringMap<int> = New StringMap<Int>()
	
	list.Insert("zabc", 2)
	list.Insert("world", 1337)
	list.Insert("abc", 1)
	list.Insert("hehe", 0712)
	
	For Local key:string = EachIn list.Keys()
		Print key
	Next
	Return 0
End Function

Output:

abc
hehe
world
zabc

If you want them in order, then you need an JsonArray using [], not an JsonObject {}.

"data" : [
    { 
        "type" : "world",
        "z" : 1,
        ...
    },
    { 
        "type" : "player",
        "z" : 2,
        ...
    },
    ...
]

Or, you access things by name if using a JsonObject [].

Local jso:JsonObject = New JsonObject(str)
Local jsoData:JsonObject = JsonObject( jso.Get("data") )
Local jsoWorld:JsonObject = JsonObject( jsoData.get("world" ) )
Local jsoPlayer:JsonObject = JsonObject( jsoData.get("player" ) )
