Arrays and random coordinates

Hi guys

I have been stuck, trying to figure out this: I have a bunch of spawning objects outside the layout and I d like them to spit projectiles in random order.

I saved their X coordinates in a array and set up a function to pair the right y value for each x value that is randomly picked (so the projectile spawn exactly in the middle of the spamming object), like this:

The problem is that only 3 out of 4/5 spawning points work, I connot figure out why....

Why are you doing this in such a complex and obscure way? Why not simply pick a random instance of the object and use it to spawn the projectile?

System pick random Hyve
...Hyve spawn Projectile
...Projectile set angle of motion to 
.. etc

Thank you, I will try that.

I designed that way because I am learning the software, I am not so much into math/program. Thank you again!
