Resolved I don't know how to search to solve it

This is a beginner's question.
I want to press a button in the game and replace the cube with a sphere.
I want to load the sphere when I press the button.
I searched because it was a basic question.
But I don't know how to find it in the official references.

Please tell me the search method from the information on the left.

 

Do you already have as script?

You could attach your GameObjects (Cube and Sphere) to the Script:

Code (CSharp):

1. public GameObject myCube;
2. public GameObject mySphere;
3.  
4. void Start()
5. {
6. myCube.SetActive(true);
7. mySphere.SetActive(false);
8. }
9.  
10. void PressMyButton()
11. {
12. myCube.SetActive(false);
13. mySphere.SetActive(true);
14. }

Now you attach that Script to the button. How you can do that, you will se in that video:

 

"SetActive"! Thank you very much. It was very helpful.
