unityscript - Unity3D - Multiple enemies patrolling multiple paths in the same script -

i'm new writing code. enemy patrol between 2 paths. when player enters detection area around enemy follow player.

if wanted more 1 enemy , multiple paths, how add code able that. creating script each enemy waste, correct?

public var enemypath1 : transform; public var enemypath2 : transform; private var target : transform = null; private var charactercontrols: charactercontroller;  function start () {     settarget(enemypath1);     charactercontrols = getcomponent(charactercontroller); }  function settarget(newtarget : transform) : void {     target = newtarget; }  function update() : void {     var lookatposition : vector3 = vector3(target.position.x,                                            this.transform.position.y,                                            target.position.z);     transform.lookat(lookatposition);     charactercontrols.simplemove(transform.forward); }  function ontriggerenter(node : collider) : void {     if(node.transform == target)     {         if(target == enemypath1)         {             settarget(enemypath2);         }         else if(target == enemypath2)         {             settarget(enemypath1);         }     } } 

this code supposed go inside enemy gameobject, right? 1 way of doing put desired paths inside array, in order supposed followed enemy.

    var paths : transform[];     var pathindex : int = 0;     // in start function:     function start ()     {         settarget(paths[pathindex]);         charactercontrols = getcomponent(charactercontroller);     }     // in function doing checking , looking next path     function ontriggerenter(node : collider) : void     {         if(node.transform == target)         {             // increment index looks next path object             pathindex += 1;             if(pathindex == paths.length)             {                 // resets first path if last 1                 pathindex = 0;             }             settarget(paths[pathindex]);         }     } 

so can add script enemy gameobjects in scene, in editor can manually set paths variable whatever paths wish in desired order, , should follow set routine.
