How to spawn objects from CSV file
Hello,
I have been trying to work out a code for awhile now that reads a CSV file, parses the data, and then plots objects based on that data (x,z). Although I am able to parse the CSV file and print the array, I am not understanding how to instantiate objects based on this data.
I have hit a roadblock and really not sure what to do at this point. Does anyone have any suggestions please? Thank you

var csvFile : TextAsset;
var prefab : GameObject;
var x = new Array();
var y = new Array();
var z = new Array();
var count = new Array();
var id = new Array();
var j = 0;
function Start(){
Longitude();
print();
}
function Longitude () {
var stringArray = csvFile.text.Replace("\n"[0],","[0]).Split(","[0]);
for(var i = 3; i < stringArray.length; i+=1){
switch (i%3)
{
case 0:
x[j] = stringArray[i];
break;
case 1:
y[j] = stringArray[i];
break;
case 2:
z[j] = stringArray[i];
j = j + 1;
break;
}
}
}
// Test to see if the array in longitude can be accessed from without. Eventually this code needs to spawn the prefabs
function print(){
for(var t = 0; t < x.length; t+=1)
{
var block = Instantiate(prefab);
block.transform.position = new Vector3(0+t, 0, 0+t);
print("The coordinates for line " + x[t] + " are " + z[t] + "." + " Height = " + y[t]);
}
}
Please edit your question and share the code that is not working otherwise we can't help.

Your problem is in setting the position (assuming your CSV file is in the right format for this script). t
is the iterator that you use to iterate over the array. So x[y] are the x coordinated, y[t] are the y coordinates, and z[t] are the the coordinates.
Now, when you print, you print correctly (you print x[t], z[t] and y[t]), but when setting the position, you use the iterator itself as the value (you use 0+t).
So change the position setting line to:
block.transform.position = new Vector3(x[y], y[t], z[t]);
