Fix Error :The name `InputManager' does not exist in the current context

What is mean this error message

The error message "The name 'InputManager' does not exist in the current context" means that the code is trying to use a class or variable called InputManager, but it cannot be found. This can happen for several reasons:

1. The InputManager class or variable might not have been defined in the current code file, or it might not have been imported from another module if it is defined in a different file.

2. The InputManager class or variable might be misspelled in the code, so the compiler cannot find it.

3. The code might be trying to use InputManager before it has been initialized or declared.

To fix this error, you will need to check the code for any of these issues and make the appropriate changes. This might involve defining or importing the InputManager class or variable, correcting any misspellings, or initializing or declaring InputManager before using it.

How to Fix this error

1. Check if the InputManager class or namespace has been imported or included in the current file.

2. If it has not been imported, add the appropriate using statement or import directive to the top of the file.

3. If the InputManager class or namespace is not part of the project, add the necessary reference or package to the project.

4. If the InputManager class or namespace has been imported or included, but the error persists, check for any spelling or syntax errors in the code.

5. If all else fails, try restarting the IDE and rebuilding the project to ensure that all necessary files are included and compiled correctly.
