Edit: Nevermind below, I changed the code significantly and made it much smaller so it's no big deal.
I'm really kind of a noob to all these expressions. Here's basically what I want to do, just need to know if there's a more efficient way to do it:
level<number>achievements gets assigned a number. If it's 2.5 or 4 or 8 or 12, it should set egg1 to 1.
level<number>achievements gets assigned a number. If it's 7 or 8, it should set silver1 to 1.
level<number>achievements gets assigned a number. If it's 11 or 12, it should set gold1 to 1.
Right now I'll be going through and editing each global variable to change it to the next sequential level as I go down the list. I just wanted to minimize the amount of clicking and number changing I have to do.
I'm just going to open the event sheet in an editor and replace every "level1achievements" with "level2achievements" and so on in each Group. I think that's the fastest and most straightforward way to do it. Tedious, but I've done worse with this game haha. I do things the hard way.
