         BuildManager buildManager;
     
     
         private void Start()
         {
             buildManager = BuildManager.instance;
             meshRend = nodes.GetComponentsInChildren<MeshRenderer>();
             EnableDisableNodeMeshRenderer(); //set node mesh render to false when first start game
         }
     
     
         public void SelectGatlingPro()
         {
             Debug.Log("GutlingPro Selected");
             buildManager.SelectTurretToBuild(gutlingPro);
             EnableDisableNodeMeshRenderer(); //set node mesh render to true when turret button clicked
         }
     
     
         public void EnableDisableNodeMeshRenderer()
         {
             if (meshRend != null)
             {
                 foreach (MeshRenderer MR in meshRend)
                 {
                     if (MR.enabled == false)
                     {
                         MR.enabled = true;
                         return;
                     }
     
                     MR.enabled = false;

Hello,

you probably want use "continue" instead of "return" in your loop. Return immidietly terminate loop, but continue jump to next element.

       public void EnableDisableNodeMeshRenderer()
          {
              if (meshRend != null)
              {
                  foreach (MeshRenderer MR in meshRend)
                  {
                      if (MR.enabled == false)
                      {
                          MR.enabled = true;
                          continue;   //was return
                      }
      
                      MR.enabled = false;
                  }
              }
          }

thank you so much guy, and if you have more time, can you explain what happen and why just change return; to continue; become work like i want.......

here is my opinoin on C# logic work:

   if (MR.enabled == false) //if MR false
   {
          MR.enabled = true; //set MR to true
          return; //then logic return and no need to read down anymore
   }
           
   MR.enabled = false; //no need to read by logic

--------------------------------------------------------------but--------------------------------------------------------------

   if (MR.enabled == false) //if MR not false (logic found not equal false in this step)
   {
         MR.enabled = true; //then logic skip this
         return; //and skip this too because both of them inside if{ }
   }
           
    MR.enabled = false; //then logic read outside if { } and found this code then set to false because logic see if up there is not ==false

simple is : when if statement meet, the logic read inside if { }............ when if statement not meet, the logic skip everything inside if { } and read next code inside foreach { }. CMIIW...................... XD

i just want to know more about logic code work........... because before test it code, i think the logic work like my ilustration above, and i think that is logic but actually not after test the code. just wonder why................
