Button Pushing Conditions-Help Please?

I'm using unity. I'm trying to make it so when I click one of three buttons, it does something unique from the other buttons. How do I set up this condition in a function? I want to say when this button is clicked, it does this, and when this button is clicked it does this. Do I have to declare a public game object for that button and then attach it to the button in unity? How do I connect the buttons in unity with the buttons declared in the script?

Here's what I'm trying to do

Code (CSharp):

1.  
2. public class factory : MonoBehaviour
3. {
4.     public GameObject sphereButton;
5.     public GameObject cubeButton;
6.     public GameObject cylinderButton;
7.  
8.     public interface Shape
9.     {
10.         GameObject CreateShape();
11.     }
12.  
13.  
14.  
15.     public class Sphere : Shape
16.     {
17.  
18.         public GameObject CreateShape()
19.         {
20.             GameObject sphere = GameObject.CreatePrimitive(PrimitiveType.Sphere);
21.             sphere.transform.position = new Vector3(0, 0, 0);
22.             sphere.GetComponent<MeshRenderer>().material.color = new Color
23.                    (Random.Range(0, 1), Random.Range(0, 1), Random.Range(0, 1), Random.Range(0, 1));
24.             Destroy(sphere, 30.0f);
25.             return sphere;
26.         }
27.     }
28.  
29.  
30.  
31.     public class Cube : Shape
32.     {
33.         public GameObject CreateShape()
34.         {
35.             GameObject cube = GameObject.CreatePrimitive(PrimitiveType.Sphere);
36.             cube.transform.position = new Vector3(0, 0, 0);
37.             cube.GetComponent<MeshRenderer>().material.color = new Color
38.                    (Random.Range(0, 1), Random.Range(0, 1), Random.Range(0, 1), Random.Range(0, 1));
39.             Destroy(cube, 30.0f);
40.             return cube;
41.         }
42.     }
43.  
44.  
45.  
46.     public class Cylinder : Shape
47.     {
48.         public GameObject CreateShape()
49.         {
50.             GameObject cylinder = GameObject.CreatePrimitive(PrimitiveType.Sphere);
51.             cylinder.transform.position = new Vector3(0, 0, 0);
52.             cylinder.GetComponent<MeshRenderer>().material.color = new Color
53.                    (Random.Range(0, 1), Random.Range(0, 1), Random.Range(0, 1), Random.Range(0, 1));
54.             Destroy(cylinder, 30.0f);
55.             return cylinder;
56.         }
57.     }
58.  
59.  
60.  
61.     public class ShapeFactory
62.     {
63.         public Shape GetShape(Button shapeButton)
64.         {
65.             if (shapeButton.tag == "Cube Button")
66.             {
67.                 return new Cube();
68.             }
69.             if (shapeButton.tag == "Sphere Button")
70.             {
71.                 return new Sphere();
72.             }
73.             if (shapeButton.tag == "Cylinder Button")
74.             {
75.                 return new Cylinder();
76.             }
77.             return null;
78.         }
79.     }
80. }

 

This just turned up on search, I'm sure there are many. Your question is really too general for this forum. It needs a tutorial.

 

I just added some code
