{
numbCoins += 1;
guiPlayer.text = "Coins = " + numbCoins;
}

///this is Gate script for control an object, It will change by time increase.


function CheckCoins()
{
if(numbCoins <2 )
{
this.renderer.material = redMat;
}
if(numbCoins >=2 || numbCoins <4)
{
this.renderer.material = yellowMat;
}
if(numbCoins >= 4 || numbCoins <8 )
   {
this.renderer.material = greenMat;

A simple solution is to place references to the player script in Gate and HUD, and assign them in the Inspector. Supposing that the player script is called PlayerScript.js, for instance, the Gate script would be something like this:

public var pScript: PlayerScript; // drag the player here

function CheckCoins()
{
if(pScript.numbCoins <2 )
{
this.renderer.material = redMat;
}
else if (pScript.numbCoins <4)
{
this.renderer.material = yellowMat;
}
else if (pScript.numbCoins <8 )
{
this.renderer.material = greenMat;
}
else 
{
Destroy(gameObject);
} 
}

Place another reference in the HUD script and use it like in Gate:

public var pScript: PlayerScript; // drag the player here

function Update()
{
    guiText.text = "Coins=" + pScript.numbCoins;
{

You can access a public variable from another script by this method.

This is your player script.

//PlayerScript.js            
var numbCoins:int =0;      //This is your public variable.
function OnTriggerEnter(GGG : Collider)
{
   if(GGG.name  == "Gate") 
   {
     numbCoins += 1;
     guiPlayer.text = "Coins = " + numbCoins;
   }
}

This is your gate script (The script from which we access PlayerScript)

//GateScript.js

var playerobject:GameObject;
var playerCoins:int=Playerobject.GetComponent("PlayerScript").numbCoins;
