Notice that the two "missing elements" of the table will be passed to the callback as additional parameters. Indeed, that second d action will be executed any time player1 is detected, no matter what coordinates.

Similarly, you can add an action that will be triggered for any player detection: Similarly, you can add an action that will be triggered for any player detection:

If you want to detect all signals raised (i.e. for logging and debugging) you can do so by observing the empty table: If you want to detect all signals raised (i.e. for logging and debugging) you can do so by observing the empty table:
