Cube Pyramid

Hey! I'm pretty new to unity and I need help trying to create a cube pyramid using cube prefabs. So far, I'm able to create two-dimensional stairs using the following code and referencing the cube prefab to an empty game object:

Code (csharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class StepsBuilder : MonoBehaviour
5. {
6.     public int height = 0;
7.     public int width = 0;
8.     public GameObject brickPrefab = null;
9.     public int widthCounter = 0;
10.     public int heightCounter = 0;
11.     public GameObject awesomeBrick = null;
12.  
13.     // Use this for initialization
14.     void Start ()
15.     {
16.         while (heightCounter < height)
17.         {
18.             while (widthCounter < width)
19.             {
20.                 awesomeBrick = (GameObject)Instantiate(brickPrefab);
21.                 awesomeBrick.transform.position = new Vector3(widthCounter, heightCounter, 0.0f);
22.  
23.                 widthCounter++;
24.             }
25.  
26.             widthCounter = heightCounter + 1;
27.  
28.             heightCounter++;
29.         }
30.     }
31.    
32.     // Update is called once per frame
33.     void Update ()
34.     {
35.    
36.     }
37. }
38.  

This makes a staircase that, depending on what the user sets the width and height to, looks basically like this (* == cube):

*
* *
* * *
* * * *
* * * * *

Now I need to basically work backwards so the steps go back down to make a two-dimensional pyramid but, where do I go from here? I've tried multiple things, but to no avail. I'm unfortunately completely stuck. Thanks in advance for the help!

 

You need to offset the start of each row by half a block * row number (minus 1)

 

Would you care to elaborate? Sorry.

 

try this. You should really calculate the height from the width as a user might enter a height greater than the width and depending on what the brick prefab is this could cause problems, maybe make the height = width. Anyway this almost works:

Code (csharp):

1.     using UnityEngine;
2.     using System.Collections;
3.      
4.     public class PyramidBuilder : MonoBehaviour
5.     {
6.         public int height = 0;
7.         public int width = 0;
8.         public GameObject brickPrefab = null;
9.         public GameObject awesomeBrick = null;
10.         public float xpos=0.0f;
11.      
12.         // Use this for initialization
13.         void Start ()
14.         {
15.         for(int i = 0; i < height; i++)
16.         {
17.             for(int j = 0; j < width; j++)
18.             {
19.                 awesomeBrick = (GameObject)Instantiate(brickPrefab);
20.                 awesomeBrick.transform.position = new Vector3(j+xpos, i, 0.0f);
21.             }
22.             width-=2; // remove 2 bricks from the width
23.             xpos++; // shift the start position of next row along 1 block can use 0.5 to shift half a block
24.         }
25.         }
26.        
27.         // Update is called once per frame
28.         void Update ()
29.         {
30.        
31.         }
32.     }

 

void Pyramid(int pNum)
{
for (int y = 0; y < pNum; y++)
{
for (int z = 0; z < pNum-y; z++)
{
for (int x = 0; x < pNum-y; x++)
{
temp = Instantiate(box, new Vector3(x + tNum, y, z + tNum),Quaternion.identity);
}
}
tNum += .5f;
}

}
