static public AimChoosedCent GetInstance if aimChoosed == null aimChoosed = new AimChoosedCent; return aimChoosed;

This is an example of a static method implementation of the singleton pattern in C#.

The method GetInstance() is static, meaning it can be called directly on the class without creating an instance of the class. It checks if the variable aimChoosed is null, indicating that an instance of the AimChoosedCent class has not been created yet. If it is null, a new instance is created and assigned to aimChoosed. Finally, the method returns the instance of aimChoosed.

This implementation ensures that only one instance of the AimChoosedCent class is created and returned each time GetInstance() is called
