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

The error message "A namespace cannot directly contain members such as fields, methods or statements" indicates that the code is missing a namespace declaration. \n\nTo fix this error, you need to add a namespace declaration at the beginning of the script. For example, you can add the following line of code at the beginning: \n\ncsharp\nnamespace MyNamespace\n{\n\n\nThen, at the end of the script, add a closing brace to close the namespace declaration: \n\ncsharp\n}\n\n\nHere is the corrected code: \n\ncsharp\nusing UnityEngine;\n\nnamespace MyNamespace\n{\n public 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\n\nMake sure to replace "MyNamespace" with the actual namespace you want to use.
