The ScreenNormalToRay method in the CameraComponent class is used to convert a normalized screen position into a ray in world space. This is particularly useful for determining the direction of a point on the screen in the 3D world, which can be used for tasks such as raycasting or determining where a user is clicking in the game world.
To use the ScreenNormalToRay method, you need to provide a Vector3 representing the normalized screen position. The method will return a Ray object that represents the direction from the camera through the specified screen position into the world.
The normalPosition parameter should be a Vector3 where the x and y components are normalized screen coordinates (ranging from 0 to 1), and the z component is typically set to 0.
// Example usage of ScreenNormalToRay CameraComponent cameraComponent = new CameraComponent(); Vector3 screenPosition = new Vector3(0.5f, 0.5f, 0f); // Center of the screen Ray ray = cameraComponent.ScreenNormalToRay(screenPosition); // Use the ray for raycasting or other purposes // For example, checking what the ray intersects with in the scene
