The ScreenPixelToRay method in the CameraComponent class is used to convert a screen pixel position into a Ray in world space. This is particularly useful for raycasting from the camera into the scene, allowing you to determine what objects are under a specific pixel on the screen.
To use the ScreenPixelToRay method, you need to provide a Vector3 representing the pixel position on the screen. The method will return a Ray that starts at the camera's position and points in the direction corresponding to the given pixel position.
This method is typically used in scenarios where you need to interact with objects in the scene based on user input, such as clicking or tapping on the screen.
// Example usage of ScreenPixelToRay
CameraComponent camera = new CameraComponent();
Vector3 pixelPosition = new Vector3(100, 150, 0); // Example pixel position
Ray ray = camera.ScreenPixelToRay(pixelPosition);
// Use the ray for raycasting
RaycastHit hit;
if (Physics.Raycast(ray, out hit))
{
// Do something with the hit object
GameObject hitObject = hit.collider.gameObject;
// Example: Log the name of the hit object
// Log(hitObject.name);
}
