Hey I'm building my game and I want to implement single and two player game, I have a confirmation dialog but I cannot find a code for that if you press eg YES it will spawn single player actors etc. Anyone have ideas/ advice?

It would be important how the confirmation dialog was implemented, code-wise. Also, any classes you created relating to the dialog and the issue at hand should be shown.

There seems to be a couple of issues with line 10. First, there is no 'showConfirmDialog' method that uses the number and types of parameters as given in the line. Second, all four of the 'showConfirmDialog' methods returns an int value (none return a String object, which you are trying to cast the return value to and set to a String variable ). Have you even review the JOptionPane class documentation before trying to use it? Please do so, it is here. You should note the class fields supplied with the class -- they should help as far as what to put for your 'if' conditions.

Oh sorry I didn't mean to include the string in this code, I tried method with an input before and forgot to delete the 'string'
