Pulling the first two characters from a string. Code not working.
WWW cityRequest = new WWW("http://www.geoplugin.net/json.gp?ip="+ currentIP); //get player location
yield return cityRequest;
var N = JSON.Parse(cityRequest.text);
currentCity = N["geoplugin_city"].Value;
currentCountry = N["geoplugin_countryName"].Value;
currentLon = N["geoplugin_latitude"].Value;
currentLat = N["geoplugin_longitude"].Value;
string shortLon = currentLon.Substring(0,2);
string shortLat = currentLat.Substring(0,2);
It looks like it would work and from what I google it should but when I actually put it into practice but when I run the program I get nothing.
currentLon: 23.43924*
currentLat: 58.23423
shortLon:
shortLan:
*do note this just random numbers and not the actual numbers that was generated by my program.
EDIT: Added image that shows issue.
No that is why I am confused, I don't get any errors it just doesn't give a value when running it on unity. I'll try to get a picture so it'll be more clear.
Okay I feel really silly relative to how much work I put into solving it.
The solution is there is no problem. It just doesn't show up on the inspector for some reason but if I actually draw it onto the game screen it shows up.
Despite all my messing around in the code, I have no idea why I never tried that.
Maybe WWW is not done before you accessed it. Try this
WWW cityRequest;
// Use this for initialization
void Start ()
{
StartCoroutine(getCityInfo());
}
// Update is called once per frame
void Update ()
{
if(cityRequest.isDone){
showResult();
}
}
IEnumerator getCityInfo(){
cityRequest = new WWW ("http://www.geoplugin.net/json.gp?ip=" + currentIP); //get player location
//Wait until the info is done receing bytes
while(!cityRequest.isDone){
yield return null;
}
}
void showResult(){
if(cityRequest != null && cityRequest.isDone){
var N = JSON.Parse (cityRequest.text);
currentCity = N ["geoplugin_city"].Value;
currentCountry = N ["geoplugin_countryName"].Value;
currentLon = N ["geoplugin_latitude"].Value;
currentLat = N ["geoplugin_longitude"].Value;
string shortLon = currentLon.Substring (0, 2);
string shortLat = currentLat.Substring (0, 2);
}
}
Or maybe you have trailing characters in the string. Use shortLon.Trim() and shortLat.Trim() to remove the leading and trailing white space then try the Substring function again.
