So I'm working on a shooter game, and I'm trying to have it so when the ship is within a certain proximity of a coin (which is spawned once an enemy is destroyed), the coin will move into the player.
I can't figure out how to detect when the coin is close to the player, and the best way to go about making the coin move towards (and touch) the player.
The expression you're looking for is:
distance(coin.X, coin.Y, ship.X, ship.Y)
As for moving the coin to the ship, there are a number of ways you could do that. I'd personally use rexrainbow's Move-To Behavior.

Thanks for replying! I'll check out the behavior, it sounds extremely useful. What event would I use to enter that expression? I'm looking, but I can't seem to find one that would fit.
You probably want to use it in system -> "every tick"
Oh, whoops. I meant what action would I use where I can enter the distance expression, sorry.
Edit: Oh sorry, I got it. System>Compare two values. Thanks!
Here's how I did it. I used a FOR EACH [COIN OBJECT], got it to check the distance and set the angle if it was as close as I wanted it to be ( < 1000 ). I added the BULLET behaviour to the coins so I could just set the angle, then a speed and the behaviour would do the rest. You can take out the 1 second delay if you want, that's not needed. By leaving it in, it makes the coins 'hover' for 1 second and then fly towards the player.

Thanks for the help, but I figured out what the others meant. Here's my WIP so far if anyone wants to test it out. :D

You have to refresh if you die, I can't figure out how to restart it. I did restart layout, but the enemies don't come back after the restart.
I like it! Is it going to be a 1942 remake? I love that game, dropped a fortune into that arcade machine when I was a kid.
Haha, that's one of my favorite arcade games. It's not a remake, but it's heavily inspired by that, and Jamestown. (If you haven't played Jamestown yet, play it now. If you loved 1942, you'll love Jamestown.)
