Problem with multiple objects using the same script

I'm not sure if that has been answered yet, but I made a research and I can't find it. I'm new to Unity and I want to make a game that have some satellites orbiting around a character. The problem is that I need the satellites to descend in a random order. For that, I've created an extern object called SatManager that manages all teh random stuff and all satellites manouvres. But when I start the game, satellites go mad. I ried to fix that by adding the this target to all the actions of the satellites script, but they continue doing strange things: they orbitate around something unexpected, there doesn't appear the satellite I want, etc.

To make descend the satellite I want, I made the variable id. Id=1 goes for spain, id=2 goes for france, id=3 goes for italy and id=4 goes to greece. But when id=2 , italy descends, but france orbits around the character in a wrong y (upper)!

Please can someone help me?

Here are the scripts (named SatManager and OrbitSat):

For the SatManager:

static var state:int = 0; (In which state we can find the object: spawning the satellite, waiting for the satellite to be shot, etc.) private var id:int = 0; (the identifier or country of the satellite that's going to be spawn) public var numberSat:int; (how many satellites I've made so far) public var spain: OrbitSat; (identifier for the spanish satellite) public var france:OrbitSat; (identifier for the french satellite) public var italy:OrbitSat; (identifier for the italian satellite) public var greece:OrbitSat; (identifier for the greek satellite)

if (state==0){ id=Random.Range(1,numberSat+1); state=1 } (there are more actions there to make more than one satellite descend but I don't use them yet so they couldn't be the error)

if (state==1){ if (id==1){ if (spain.descend==0){ spain.descend=1; spain.transform.position.y=30; spain.transform.rotation.eulerAngles.y=204; spain.state=1; } } if (id==2){ if (france.descend==0){ france.descend=1; france.transform.position.y=30; france.transform.rotation.eulerAngles.y=204; france.state=1; } } if (id==3){ if (italy.descend==0){ italy.descend=1; italy.transform.position.y=30; italy.transform.rotation.eulerAngles.y=204; italy.state=1; } } if (id==4){ if (greece.descend==0){ greece.descend=1; greece.transform.position.y=30; greece.transform.rotation.eulerAngles.y=204; greece.state=1; } } state=2 }

For the satellites:

public var target : Transform; (the character) static var state:int = 0; (the same as the SatManager) static var descend:int = 0; (if the satellites had descended or nor) public var id:int = 0; (the country of the satellite)

function Update () { if (this.state==0){ this.transform.position.x=-103.68; this.transform.position.y=-101.67; this.transform.position.z=105.83; } if (this.state==1){ this.transform.Rotate(Vector3.up,Time.deltaTime*12); this.transform.position.x=target.transform.position.x+(Mathf.Sin((transform.rotation.eulerAngles.y+90)*Mathf.Deg2Rad)*30); this.transform.position.z=target.transform.position.z+(Mathf.Cos((transform.rotation.eulerAngles.y+90)*Mathf.Deg2Rad)*30); this.transform.position.y-=15*Time.deltaTime; if (this.transform.position.y<1.84){ this.transform.position.y=1.84; this.state=2; } } if (this.state==2){ this.transform.Rotate(Vector3.up,Time.deltaTime*12); this.transform.position.x=target.transform.position.x+(Mathf.Sin((transform.rotation.eulerAngles.y+90)*Mathf.Deg2Rad)*25); this.transform.position.z=target.transform.position.z+(Mathf.Cos((transform.rotation.eulerAngles.y+90)*Mathf.Deg2Rad)*25); } }

Thanks in advance!
