M... You can do that with values. You want to count how many times an objects has collapsed with another object? Do this:
- Add Object 1 (O1) & Object 2 (O2)
- Add a Value and name it something like "Bumps-counter"
- Add a when "When O1 bumps O2"
- Add a block "Increase "Bumps-counter" by "1"
There you go. You're now counting how many times an objects has touched another object. This will create lives on a game.
