How to generate set number of cubes randomly on a plane?

Hi,

As the title says, I'm a bit confused as to how I can generate a set number of cubes (say, 100) on a plane, in a way that some are stacked on top of each other (in piles, essentially), and others simply lay on the plane. I don't want to generate the blocks as the player moves (like in Minecraft) but rather, create the 100 blocks and arrange them on the plane in a random way as described above. Thanks!

(If you're wondering, I tagged this question as 'documentation' since there's no other tag available)

 

first make a prefab of the cube you wanna spawn and reference it in ur script:

public GameObject cubePrefab;

now we loop through however many cubes your wanna spawn with a for loop, generating 2 floats randomly between the edges of your plane each time and putting a cube there (this asssumes your plane is at the origin and is scaled on the x and z by 10):

for (int i = 0; i < 100; i++){

float x = Random.Range(-10f, 10f);

float z = Random.Range(-10f, 10f);

Instantiate(cubePrefab, new Vector3(x, 1, z), Quaternion.identity);

}

the stacking is a little more complicated. first, make x and z declared at the top of ur script, declare a new

float increment = 0

at the top, and declare y as 1 at the top as well. then i'd just use a random.range(0, 1) every time you run the for loop, and set the y level on the instantiation to one above whatever it usually is if the random is 1, and normal if its 0:

for (int i = 0; i < 100; i++){

     if (Random.Range(0, 1) == 1){

          Instantiate(cubePrefab, new Vector3(x, y + increment, z), Quaternion.identity);

          i++;

          increment++;

     } else {

          increment = 0;

          x = Random.Range(-10f, 10f);

          z = Random.Range(-10f, 10f);

          Instantiate(cubePrefab, new Vector3(x, y, z), Quaternion.identity);

}}

pls reply if it breaks i wont have a chance to test if it works sry

(btw put this code in the start function)
