Hi There,
I thought of an idea and then wondered how I could get it into Unity and have hit a block, mainly because of my lack of mathematical ability. Perhaps someone can help on this…
Basically it is a Cube 1000x1000x1000 and is made up of smaller Cubes 1x1x1. I started placing Cubes beside each other and soon discovered… it’s going to take a while…Is there a mathematical quick way to do this?
That’s the first part. Then I need to texture each Cube individually. Is this even possible when there are so many? I need to be able to identify a Cube in a coordinate system and read it’s texture.
//This creates a large block of objects.
//Add script to an empty object. The creation of the this script will be in releation to where the empty block is placed.
var prefab : GameObject;
var cubeSize : int = 5 ;
var offset : int = 1 ; //Distance between cube centers
function Start(){
for (var zz = 0;zz<cubeSize*offset;zz+=offset){
for (var yy = 0;yy<cubeSize*offset;yy+=offset){
for (var xx = 0;xx<cubeSize*offset;xx+=offset){
// Begin the instantiation where the empty object is.
Instantiate (prefab, Vector3(transform.position.x + xx, transform.position.y + yy, transform.position.z + zz), Quaternion.identity);
//Added this line so you can actually see how the cubes are being populated
yield WaitForEndOfFrame;
}
}
}
}
You won’t be able to make 1000x1000x1000 separate objects, not even close. You realize that’s 1 billion objects, right? If you’re trying to do something like Minecraft, you have to build meshes using the Mesh class, and be smart about not creating geometry that you won’t see anyway.
public Transform cubePrefab;
public int rows,columns,depth;
public float padding;
// Use this for initialization
void Start () {
for(int i =0; i < depth; i ++) {
for(int j=0;j< columns;j++){
for(int k=0; k < rows;k++){
Vector3 pos = new Vector3(k * padding,j * padding,i * padding);
//print(pos);
Transform foo = (Transform) Instantiate(cubePrefab,pos,Quaternion.identity);
}
}
}
}
