    Default A Game Error.

    Where the Error seems to direct to my player class.


    The actual error:

    Welcome to the forum! Please read this topic to learn how to post code in code or highlight tags and other useful info for new members.

    "X cannot be resolved to a variable" means the compiler does not recognize the variable variable - it was not declared at all or within the scope it was used.
