have array target person of most priority/stick with top prior

Hello Everyone.

I am currently making a script that allows it to detect players and their ships, and then target them according to priority number. (the lower the number, the more important it is).

I have a somewhat functioning one, but it keeps rapidly changing between targets, as well as being unable to focus on the top target. (it targets him for a second before targeting a less important Transform again).

It is at the FindTarget function.

would someone be nice enough to take a look and let me know where I messed up at? Thank you for your time!
