This is an example of a very simple minesweeper game.


Create a controller object, and drop the following script into it.

integer size = 6;     //Size of the game 3 is a 3x3, 5 is a 5x5.
float percent = .1;    //Percentage of squares that are mines.
 
 
list mat;
list mines;
integer found;
integer rand;

    }

        if (i%size != 0) {
            llShout(rand+i-1, (string)(i-1));
