load Object coordinates from PHP Database to place object

Questions & Answers

Hello there…
i have some problem to place an object to the coordinates, where first save in a PHP database.
first of all:
my script save the hit.point, of an object, that i place with raycast:
the hit.point have this format: (xx.xxxx,yy.yyyy,zz.zzz) always WITH ()
so i convert to a string:

koordinaten = hit.point.x.ToString()+","+hit.point.y.ToString()+","+hit.point.z.ToString();

Then i save it with a function :

    function candle_speichern () {

 var form = new WWWForm();

    form.AddField("myform_name",koordinaten);
    print(koordinaten);
    var w = WWW(URL_save, form);
    yield w;
    if (w.error != null)
        print(w.error);    
    else
        print("Saved");    
}

Then i want to load this entry, when i start:

var URL = "http://mydomain.de/read_candle.php";
var candle : GameObject;
static var eintrag: String;

function Start () {
candle_load();
}

function candle_load() {
	var w = WWW(URL); 
	yield w;
        if (w.error != null)
        print(w.error);    
    else
        eintrag = w.text;
        print("Eintrag:"+eintrag);
        	var words = eintrag.Split(","[0]);
 			for(i = 0; i < words.Length; i++){
			var load_x: int = float.Parse(words[0]);
			var load_y: int = float.Parse(words[1]);
			var load_z: int = float.Parse(words[2]);

			print("Split x: "+load_x);
			print("Split y: "+load_y);
			print("Split z: "+load_z);
			//var c_posx = float.Parse(load_x);
			//var c_posy = int.Parse(load_y.ToString());
			//var c_posz = int.Parse(load_z.ToString());

			//print("x float: "+c_posx);
			//print("y float: "+c_posy);
			//print("z float: "+c_posz);


	var position = Vector3(load_x, load_y, load_z);
	
	print("POsition:"+position);
	Instantiate(candle, position, Quaternion.identity);
	
}
	}

i received allways this error:

FormatException: Unknown char: 
System.Double.Parse (System.String s, NumberStyles style, IFormatProvider provider)
System.Single.Parse (System.String s)
start+$candle_load$15+$.MoveNext () (at Assets/Scrips/start.js:23)

**and the object was not positioned on the terrain, but the coordinates where true an i see it with the print command…but i dont know why and where i can solve this problem…
do you have any ideas?? Or exist’s another way to save and load the coordinates from an object?

thx a looooot!!**

First make sure your point is being saved on the server correctly. Check whatever files or database you have there. Then make sure the point is being returned as you expect, just hit that URL with any web browser to see what comes back. If it looks like a proper x,y,z in text form, then check each word to make sure it split correctly. You may want to add .Trim() to that to clear any junk that might come with it

Also, you have

var load_x: int = float.Parse(words[0]);

don’t you mean load_x : float ?

And the parse func likes floats to have .0 as in “1.0” rather than just “1” and/or ‘f’ appended, as in “1f” or “1.0f”, so you could try appending that to the word before parsing it.

Dammned fucking bullshit!!

This stupid variables dosnt convert or fucking transform to work!!
what ever i do: frong input string, unknownd char, it not work with ANY converting:
parse,TryParse,parseFloat,float.Parse,float.TryParse,int.TryParse…

stupid blame system…
