void Start() {
Thread.CurrentThread.CurrentCulture = CultureInfo.InvariantCulture
}I think you have a problem with CultureInfo and not with the Drawing API.
What I mean is:
Depending on the country, the integer and fractional parts of a number can be separated by a dot or comma.
This means that the code (10.99).ToString() can return "10.99" and "10,99".
If you have the second case, you will get an invalid string when you use a comma-separated Join.
The best way to solve the problem is to use CultureInfo.InvariantCulture in ToString and Parse methods.
]]>In Unity Editor I save and load Shapes without any issue.
On iOS device when loading shapes I get vertical lines from North to South poles of the earth.
I attach an image to see the issue on the device.
Below is my code for loading and saving shapes:
// Function to load shapes from PlayerPrefs
public void LoadShapes()
{
if (!PlayerPrefs.HasKey("Shapes")) return;
string xmlContent = PlayerPrefs.GetString("Shapes");
OnlineMapsXML xml = OnlineMapsXML.Load(xmlContent);
if (xml != null) {
foreach (OnlineMapsXML shapeNode in xml)
{
if (shapeNode.name == "Line") {
string pointsStr = shapeNode.Get<string>("Points");
//Debug.Log(pointsStr);
pointsStr = pointsStr.Replace("[", "");
pointsStr = pointsStr.Replace("]", "");
string[] pointsArray = pointsStr.Split(",");
List<OnlineMapsVector2d> points = new List<OnlineMapsVector2d>();
for (int i = 0; i < pointsArray.Length-1; i += 2)
{
double x = double.Parse(pointsArray[i]);
double y = double.Parse(pointsArray[i + 1]);
points.Add(new OnlineMapsVector2d(x, y));
}
OnlineMapsDrawingLine shape = new OnlineMapsDrawingLine(points);
shape.name = shapeNode.Get<string>("Name");
shape.color = shapeNode.Get<Color>("Color");
shape.width = shapeNode.Get<float>("Width");
OnlineMapsDrawingElementManager.AddItem(shape);
SavedLines.Add(shape);
}
if (shapeNode.name == "Poly")
{
string pointsStr = shapeNode.Get<string>("Points");
// Debug.Log(pointsStr);
pointsStr = pointsStr.Replace("]", "");
pointsStr = pointsStr.Replace("[", "");
string[] pointsArray = pointsStr.Split(",");
