The WithZ method of the Vector3 struct allows you to create a new Vector3 instance with a specified Z component, while keeping the X and Y components unchanged. This method is useful when you need to modify only the Z component of a vector without affecting the other components.
To use the WithZ method, call it on an existing Vector3 instance and pass the new Z value as a parameter. The method returns a new Vector3 instance with the updated Z component.
Vector3 originalVector = new Vector3(1.0f, 2.0f, 3.0f); Vector3 newVector = originalVector.WithZ(5.0f); // newVector is now (1.0, 2.0, 5.0)
