Help in GameMaker

Hello there!
I'm trying to enter the GameJam but I'm having trouble making an object rotate around a certain point at a Fixed Radius.
I'm trying this formula https://kodlogs.com/131799/game-maker-rotate-object-around-a-poi… but it's ot working.
Anyone would be kind enought to help out?
To everyone taking part in the GX Jam....
Here's a useful tutorial on making an endless runner in GMS. Hopefully it's a good kickstart for anyone new to GMS or just new to game dev in general:



Umm so i tried applying some screen wrap to enemies, and it made things a bit tougher to dodge, does this look fine? or should i remove it?(for conext, enemies spawn after an offscreen timer ends then it changes to a new timer that does another pattern)
hello I can be a game but I can't put UFOs for my style of play does it matter?
