If you really need an instance right away, call drawingElement.DrawOnTileset method.
This will cause the element to be drawn and create an instance.
Hello.
The problem is that in DrawCircle method you are creating OnlineMapsVector2d[], and in OnCircleClick method you are trying to cast it to Vector2[].
In OnCircleClick method, you also need to use OnlineMapsVector2d[].
Hi, sorry again I wanted to ask about element.instance
Why can't I immediately get the instance of the drawing each time it is created?
Script Example
if(Input.GetMouseButtonUp(0))
{
if(poly != null && poly.name == "Rect")
{
Vector2[] vertices2D = new Vector2[]{pointRect[0], pointRect[1], pointRect[2], pointRect[3]};
poly.Dispose();
if(warna.value == 0)
polygon = new OnlineMapsDrawingPoly(vertices2D, Color.blue, 1, Color.blue);
else
polygon = new OnlineMapsDrawingPoly(vertices2D, Color.red, 1, Color.red);
poly = OnlineMapsDrawingElementManager.AddItem(polygon);
poly.name = "Rect";
if(poly != null)
OnlineMaps.instance.Redraw();
poly.OnClick += OnElementClick;
poly.OnPress += OnElementPress;
poly.OnRelease += OnElementRelease;
Debug.Log(poly.instance.name);
poly = null;
onlineMaps.blockAllInteractions = false;
isDragging = false;
isDrawingSquare = false;
n = 0;
}
}In the script above, whenever I try to immediately check the instance of the drawing (In this case the instance.name), it always showed an error in which the object I referenced is not there.
NullReferenceException: Object reference not set to an instance of an object
DrawArrow.DrawKotak () (at Assets/Scripts/DrawArrow.cs:404)
DrawArrow.IsDrawing () (at Assets/Scripts/DrawArrow.cs:278)
DrawArrow.Update () (at Assets/Scripts/DrawArrow.cs:82)The problem is that in DrawCircle method you are creating OnlineMapsVector2d[], and in OnCircleClick method you are trying to cast it to Vector2[].
In OnCircleClick method, you also need to use OnlineMapsVector2d[].
For the atlas example I'm using is the DrawCircleAroundMarker.cs.
Keep in mind that the only thing that I added in the DrawCircleAroundMarker.cs is the OnCircleClick function and also a bool so I can only create the marker and the circle when the bool is true;
Here's the code
public class DrawCircleAroundMarker : MonoBehaviour
{
/// <summary>
/// Radius of the circle
/// </summary>
public float radiusKM = 0.1f;
/// <summary>
/// Number of segments
/// </summary>
public int segments = 64;
public Vector2[] circlePoint;
public bool drawCircle;
/// <summary>
/// This method is called when a user clicks on a map
/// </summary>
private void DrawCircle()
{
if(Input.GetMouseButtonDown(0))
{
// Get the coordinates under cursor
double lng, lat;
OnlineMapsControlBase.instance.GetCoords(out lng, out lat);
// Create a new marker under cursor
OnlineMapsMarkerManager.CreateItem(lng, lat, "Marker " + OnlineMapsMarkerManager.CountItems);
OnlineMaps map = OnlineMaps.instance;
// Get the coordinate at the desired distance
double nlng, nlat;
OnlineMapsUtils.GetCoordinateInDistance(lng, lat, radiusKM, 90, out nlng, out nlat);
double tx1, ty1, tx2, ty2;
// Convert the coordinate under cursor to tile position
map.projection.CoordinatesToTile(lng, lat, 20, out tx1, out ty1);
// Convert remote coordinate to tile position
map.projection.CoordinatesToTile(nlng, nlat, 20, out tx2, out ty2);
// Calculate radius in tiles
double r = tx2 - tx1;
// Create a new array for points
OnlineMapsVector2d[] points = new OnlineMapsVector2d[segments];
// Calculate a step
double step = 360d / segments;
// Calculate each point of circle
for (int i = 0; i < segments; i++)
{
double px = tx1 + Math.Cos(step * i * OnlineMapsUtils.Deg2Rad) * r;
double py = ty1 + Math.Sin(step * i * OnlineMapsUtils.Deg2Rad) * r;
map.projection.TileToCoordinates(px, py, 20, out lng, out lat);
points[i] = new OnlineMapsVector2d(lng, lat);
}
// Create a new polygon to draw a circle
OnlineMapsDrawingElement poly = OnlineMapsDrawingElementManager.AddItem
(new OnlineMapsDrawingPoly(points, Color.red, 3, Color.red));
poly.OnClick += OnCircleClick;
}
}
