Reading json file
how do I read?
Json:
{
"data":[[1.0, 1.5,2.0],[4.0, 4.5, 5.0]]
}
C#:
public class test : MonoBehaviour {
string path;
string jsonString;
void Start () {
path = Application.streamingAssetsPath + "/acadunity.json";
jsonString = File.ReadAllText(path);
Creature Lines = JsonUtility.FromJson<Creature>(jsonString);
print(Lines.data[0]);
}
}
[Serializable]
public class Creature{
public int[] data;
}
ERROR!!!!
I'm not sure this is the only problem, but your class data field is of type int [], and the data in the json file contains Vectors.
Try this :
[Serializable]
public class Creature
{
public Vector3 [] data;
}
I get:
(0.0, 0.0, 0.0)
json:
{
"lines":[[1,0.3544,0.0],[5.0,0.0,0.0]
]}
Did you try the opposite ? Serializing an object and look at the son file ?
No, is there another way to read? and I want to read the first number "1" can you tell me how?
json:
{
"number":[
{"x":439.0,"y":234.0,"z":342.0},{"x":1.0,"y":2.0,"z":3.0}
]
}
any idea? to get x or y or z.
