C# Error: "A namespace cannot directly contain members such as fields, methods or statements"

The error message is indicating that a namespace cannot directly contain members such as fields, methods, or statements. \n\nIn this case, it seems that the code you provided is inside a namespace. To fix the error, you can either remove the namespace declaration or move the entire code block outside of the namespace. \n\nHere's an example of how the code would look without the namespace:\n\ncsharp\nusing UnityEngine;\n\npublic class Bird : MonoBehaviour\n{\n public float jumpForce = 5f;\n private Rigidbody2D rb;\n\n void Start()\n {\n rb = GetComponent<Rigidbody2D>();\n }\n\n void Update()\n {\n if (Input.GetKeyDown(KeyCode.Space))\n {\n Jump();\n }\n }\n\n void Jump()\n {\n rb.velocity = Vector2.up * jumpForce;\n }\n}\n\n\nMake sure to check if there are any other issues or compile errors after making this change.
