Tic-tac-toe game command questions

Hello,

My client has planned to make tic-tac-toe game and would like know how to count how many actives there are in one row. She planned that she would use the following command:
Upon pressing “Space bar”
Active: Paste into background...

She has noticed that the pasted objects are duplicates. The questions are:
1.How to make it the way that when the player presses the key, a number would be added to the counter?
2.How to count the objects on different directions?

My client would still like know how to count how many actives there are in one row. She would like to know how to count them in these directions:

Does anyone know how to do it?

She has planned that she would make the game for two players. It should be compared which one has more actives on a row. How to do it?
