The GetRay method in the Editor.NativeRenderingWidget class is used to generate a Ray from a specified local position within the widget. This method is particularly useful for translating 2D screen coordinates into a 3D ray, which can be used for various purposes such as raycasting or determining the direction of a point in 3D space.
To use the GetRay method, you need to provide a Vector2 parameter that represents the local position within the widget. This position is typically a point on the screen or within the widget's rendering area. The method will return a Ray object that originates from the camera and passes through the specified local position.
// Assuming 'widget' is an instance of Editor.NativeRenderingWidget
Vector2 localPosition = new Vector2(100, 150);
Ray ray = widget.GetRay(localPosition);
// Use the ray for further operations, such as raycasting
// Example: Check if the ray intersects with any objects in the scene
RaycastHit hitInfo;
if (Physics.Raycast(ray, out hitInfo))
{
// Handle the intersection
GameObject hitObject = hitInfo.collider.gameObject;
// Perform operations with the hit object
}
