Help with spawning enemys and wildcard alternative

I have two questions ,

1] In construct 2 expressions is there something representing similar to (*) astrick wildcard?

2] How do I make enemys spawn at a certain distance from the player (x pixels) every time the player covers a certain distance (y pixels).

1) In what context would you need this? I haven't really missed them myself so asking where you'd need to use them :)

2) Something like this:

player.distanceTravelled = y

..   create object enemy at (player.x - x, player.y)

..   player.distanceTralled = 0

Depending on how your player moves you'll need to add into distanceTravelled every tick.

2)Thanks, that solves it.

1) I don't really 'need' this but it would be better if I could use it in mathematical expressions, such as finding all the even numbers between certain intervals.
