string plus int equals the name of the variable? How?

Question

I have 6 clothing textures.

 public Texture2D clothe1;
 public Texture2D clothe2;
 public Texture2D clothe3;
 public Texture2D clothe4;
 public Texture2D clothe5;
 public Texture2D clothe6;

I wish to assign one of them to a material. It will be done by checking a player prefs int variable.

The variable is assigned to an int variable called "Top"

So I basically want to say something like

         gameObject.renderer.material.mainTexture = "clothe" + Top.ToString();

emphasis on ""clothe" + Top.ToString();"

because then it equals clotheWHATEVERTHENUMBERIS

which would equal one of the textures..

But its not working. How would I achieve this?

nevermind, i solved it like this:

 if(Top == 1) {
             gameObject.renderer.material.mainTexture = clothe1;
         } else 
         if(Top == 2) {
             gameObject.renderer.material.mainTexture = clothe2;

I knew you would do it this way, so I suggested a Switch Statement :D

 switch (Top)
 {
     case 1:
         gameObject.renderer.material.mainTexture = clothe1;
         break;
     case 2:
         gameObject.renderer.material.mainTexture = clothe2;
         break;
     default:
         gameObject.renderer.material.mainTexture = clothe1;
         break;
 }

Avoid 6 deep nested ifs!

Sometimes answering on unity answers is so frustrating. I'll give you a thumbs up for cold blood.

I know it works in JS, not so sure about C#...

I use .ToString()

JS Example

 clone = Instantiate(nextBlockObject, newPlacement, Quaternion.Euler(0,0,turnAngle*nextPos));
         cloneCount += 1;
         clone.name = ("clone-"+nextBlockObject.name.ToString()+cloneCount.ToString());

Cannot implicitly convert type string' to UnityEngine.Texture'

     gameObject.renderer.material.mainTexture = ("clothe" + Top.ToString());

Top.ToString() is equal to 1

so it reads clothe1

which is

     public Texture2D clothe1;

but it doesnt like it being a string when the actual variable is a texture.

The whole reason is because Top can change up to 6 and there are 6 clothe1-6 variables...

I think the usage is different in C#

@meat5000 ToString in JS and C# bot work pretty much the same. Problem is he is assigning string directly to texture property of material, instead of actually finding his the texture with that name first, and then assigning it.

@Lovrenc, How do I assign it then?

if i understand ... you cant create a name variable with string Have many options to do that, dictyonari,hashtable,Enums. or something like that can be more powerful and elegant but i can ,hope, get u an easy form.

mmmhhhh..

 public Texture2D clothe1;
 public Texture2D clothe2;
 public Texture2D clothe3;
 
 public Texture2D targetClothe;
 
 public void ChangeMainTexture(){
   
   int myTop = PlayerPrefs.GetInt("myTop")
 
   switch(myTop){
 
     case 1 :
          targetClothe =  clothe1;
       break;
     case 2 :
          targetClothe =  clothe2;
       break;
     case 3 :
          targetClothe =  clothe3;
       break;
 
   }
 
   gameObject.renderer.material.mainTexture = targetClothe;
 }

Can use string in switch if u want, or use Resources.Load() for load with string match, somethin like that

 gameObject.renderer.material.mainTexture = Resources.Load("/materials/textures/clothe" + Top,Texture);

Take a read about Resources folder and his access.This method its good idea if you do before gameplay,because have a heavy memory/procces impact,the other referencing in variables its better idea,ever you can, if you do during gameplay

Can be syntax error in myTop declaration, dont tried,im not a programmer C# :).Anyway you can explore more options to do that, you have many many ways.

Hope this works. Sorry for my english, its pretty pretty low cheers

i dont know the method networkView.RPC(),i never take a look at networks. But if u give a int value to getTop()

 public void getTop (int Top) {
          switch(Top){
  
 case 1 :
 targetClothe = clothe1;
 break;
 case 2 :
 targetClothe = clothe2;
 break;
 case 3 :
 targetClothe = clothe3;
 break;
  
 }
  
 gameObject.renderer.material.mainTexture = targetClothe;
 
     }

or can do ...

     public void getTop (int Top) {
   
      
     gameObject.renderer.material.mainTexture = Resources.Load("/materials/textures/clothe" + Top,Texture);
      
     }

i dont remember if its -Texture or -Texture2D in Load().This is you have the textures in "local" folder in your assets project like Resources/material/textures, sure u can do that if u want take the texture of www, but i dont know exactly how,take a look unity help.
