How to work with Timestamp data in Unity
Hi everyone, I'm currently working with a folder of JSON files which are collected through a tracking experiment with a drone. The data contains position, rotation and timestamp of the drone while it's moving and levitating inside the tracking system. What I'm currently doing is trying to simulate the movement of the drone inside Unity using those data. So far, I've managed to parse the position and rotation from the data to an object inside Unity and extract the timestamp to System.DateTime in Unity. However, I don't how to work with the timestamp. I want to use the timestamp to match the position and rotation of the object (i.e: at this timestamp, the drone should be at this position(x,y,z) and has the rotation(x,y,z,w)). Can someone help me with this problem, really appreciate your help :D Here is my current code:
void Update()
{
if (loaded)
{
for(int i = 0; i <= pos_data.Count; i+= 10)
{
Cube.transform.position = pos_data[i];
Cube.transform.rotation = rot_data[i];
}
}
else
{
LoadJson();
//startTime = datetime[0];
loaded = true;
}
}
public void LoadJson()
{
string HeadPath = @Application.dataPath + "/Data/" + "drone_data_1.json";
string HeadJsonhold = File.ReadAllText(HeadPath);
var data_ = JSON.Parse(HeadJsonhold);
for (int rows = 0; rows <= data_.Count; rows += 10)
{
pos_data.Add(new Vector3(data_[rows]["location"]["x"].AsFloat, data_[rows]["location"]["y"].AsFloat, data_[rows]["location"]["z"].AsFloat));
rot_data.Add(new Quaternion(data_[rows]["rotation"]["x"].AsFloat, data_[rows]["rotation"]["y"].AsFloat, data_[rows]["rotation"]["z"].AsFloat, data_[rows]["rotation"]["w"].AsFloat));
Time = System.DateTime.ParseExact(data_[rows]["Timestamp"], "yyyyMMddHHmmss",null);
//Debug.Log(Time);
}
}
there is something I dont understand, you want the timestamp to replicate the movement/orientation over time, riight? if so, why are you overriding Time data every for cicle? Time should be an array/list similar to rot_data for having the position orientation over time, right?
