i wanna code something in a 2d sprite pls help

these red squares are my 2d sprites that i wanna code, basically i want to make them visible or invisible using a switch case, but to do this i need to add a c# file to the sprite to be able to reference it in my main c# file, can i get some help

 

From the way you worded your question, it looks like you're asking how to do the above. The answer is that you drag the second script from your project window onto the object the exact same way you added the first script.

If your question is something else, please clarify.

If all you want to do is toggle the visibility of the sprites, an if statement is a lot simpler to do than a switch statement. Look up some tutorials on youtube to learn more.

 

I'm struggling to understand what you need... this can be a useful template to help in technical communications:

How to report your problem productively in the Unity3D forums:

http://plbm.com/?p=220

This is the bare minimum of information to report:

- what you want
- what you tried
- what you expected to happen
- what actually happened, especially any errors you see
- links to documentation you used to cross-check your work (CRITICAL!!!)

If you post a code snippet, ALWAYS USE CODE TAGS:

You may edit your post above.

 

basically what I want is in the update, you can see there is an empty if statement, I want to make it so when the condition of that if statement happens (i.e. when i press f) the red cubes go invisible

 

Set the DieCube's alpha to 0 when you press F.

 

If you make a prefab of the red square thing, pass it into the script like

public GameObject redSquare;

Code (CSharp):

1. if (Input.GetKeyDown("F"))  {
2.  
3.   redSquare.SetActive(false);
4.  
5. }
