So I'm trying to make turrets shoot 360 degrees at the same time, using multiple instances of the same object. I thought the best way to do this would be by spreading values and using fast loops, however I can not seem to get it to work. Any ideas? What's the proper way to achieve this? Anyone got an example or anything to share?
Thanks, Vetmora

You don't need spread values or fast loops.
You didn't say exactly what you're trying to achieve, so I'm going to assume that the turrets are all supposed to shoot at the player once every second, when they are within range.
Anything in italics is an alterable value.
// Aim turret.
+ Always
-> Turret: Set Angle to ATan2(Y("Turret")-Y("Player"), X("Player")-X("Turret"))
-> Turret: Set Range to Sqr(((X("Turret")-X("Player")) pow 2)+((Y("Turret")-Y("Player")) pow 2))
// Fire bullet.
+ Range("Turret") <= FiringRange("Turret")
+ Restrict actions for 1 second
-> Create Bullet at 0,0 from Turret
// Set bullet movement vector.
+ Flag 0 of Bullet is OFF
-> Bullet: Set XPos to X("Bullet")
-> Bullet: Set YPos to Y("Bullet")
-> Bullet: Set Angle to ATan2(Y("Bullet")-Y("Player"), X("Player")-X("Bullet"))
-> Bullet: Set XVel to Cos(Angle("Bullet"))*Velocity("Bullet")
-> Bullet: Set YVel to 0-Sin(Angle("Bullet"))*Velocity("Bullet")
-> Bullet: Set Flag 0 to ON
// Move bullet.
+ Always
-> Bullet: Set XPos to XPos("Bullet")+XVel("Bullet")
-> Bullet: Set YPos to YPos("Bullet")+YVel("Bullet")
-> Bullet: Set X position to XPos("Bullet")
-> Bullet: Set Y position to YPos("Bullet")

Hey Sketchy, thanks for the reply. I've just tried this and it doesn't seem to work. The turrets look at the player so nothing wrong there but they're not shooting any bullets... Don't think I entered anything wrongly.

Did you set the alterable values "FiringRange" and "Velocity"?
I just checked it, and it works fine:

Yep, don't worry I got it working now, thanks. One of the events was too high on the list  Woops... Thanks heaps, I'd been searching for ages for one of these

Actually, when I inputted this into my game after I was sure it worked, something went weird. The turrets work fine until I move the player in-game then they stop. If I stay still for a few seconds they start again, and stop when I move. Any idea why this could be happening? I havn't changed the code at all.

Again, my own error. I had somewhere an event that was setting the global timer to 0 when left/right was pressed therefore resetting the restrict actions shoot. My bad

Ah, okay. I was just going to say I had no clue what could be causing that
@Jon: Quite a lot. Like make an actual complete game for starters
