Getting tic tac toe game to switch players

in Programming Questions • 3 years ago

Hello, I tried to wrap my head around the concept but have no idea how to execute it.
I've made a tic tac toe game.
I've made an array to have 2 players.
char[] player = new char[2];
player[0] = 'X';
player[1] = 'O';
My problem is trying to get these 2 players to alternate.
I was told to put "playerIndex = !playerIndex;" under mouseClicked function but obviously processing tells me "Cannot find anything named playerIndex" so what do I need to add or define in order to get my players to switch??
Thanks!

not to be harsh but don't you think you should learn more of the basics of programming before you start making games?

unfortunately if it were my choice I wouldn't be attempting games either, but I am being forced for a class.

but then you're taking a class that's too advanced

As the name implies, playerIndex shouldn't be a boolean (suggested by the ! operator) but an integer:
int playerIndex = 0;
and in the mouseClicked:
playerIndex = 1 - playerIndex;
which you use as player[playerIndex] of course.

I tried using the integer before but I get over the player[playerIndex] an error that says "insert "AssignmentOperation Expression" to complete Expression"

OK, I was suspecting something like that...

You are supposed to do something with player[playerIndex], like displaying it or something.

Currently, I don't know how you plan to use it, I just show how to alternate them.

Well, I answered your question, showing how to switch "players".
