I don't know of a tutorial exactly like that, but parts would be easy and others not so much. If this is your first run in C2, I recommend looking at a few tutorials to see how the events process and such.
I would set up an Array to be the size of the minesweep grid. You would have to either manually enter the 0s, 1s, 2s ect OR write an event to proceduraly generate the numbers. (That might be hard...) Then draw a grid of sprites (or learn about the tilemap object and use it) on the screen. Add the Mouse object so you can set up something like
ON CLICK MOUSE_>
- If over gridtile->
- {use variables or something to find the location in the array} and compare those variable to the array value
- Change the sprite and any nearby sprites according to the array values (there is a lot to this procedure...)
I dont have the time to put a template together, but it would be a neat little setup if you can get someone to get it started for you...
