Can't build a Vector3 array
TLDR: Anyone have a working solution for inserting Vector3's into an array?
Hello friends, I'm trying to build a Vector3 array to store a bunch of locations. I started by simply using
var positions = Vector3[]
However, I soon learned that you can't use .Push or .Add with Vector3 for whatever reason. So I searched and found this solution: [http://answers.unity3d.com/questions/60191/arraypush-for-vector3-or-how-to-add-items-to-vecto.html][1]
So I tried using his first sample code:
import System.Collections.Generic;var positions = List.();function AddItem (var item : Vector3) {positions.Add(item);}
However, Unity would give errors regarding an "Unexepected token" for the period on var positions = List.();. I tried to remove the period, and got this error: BCE0157: Generic types without all generic parameters defined cannot be instantiated. Thats about the limit of what I know about List, so I decided to try his next solution.
var positions : Vector3[];function AddItem (var item : Vector3) : Vector3[] {var temp : Vector3[] = new Vector3[positions.Length + 1];temp[temp.Length - 1] = item;for(var i : int = 0; i < positions.Length; i++) {temp[i] = positions[i];}}
There were no errors on this code, however for whatever reason, this doesn't actually insert data into the positions array! I checked that the item parameter is passing through successfully on AddItem(), and it is. So its just not being stored in the array for whatever reason.
If anyone has a working solution to this, would be much appreciated! Thanks [1]: http://answers.unity3d.com/questions/60191/arraypush-for-vector3-or-how-to-add-items-to-vecto.html125
in your first code, just replace positions with:
import System.Collections.Generic;
var positions = List.<Vector3>();
function AddItem(var item : Vector3) {
positions.Add(item);
}
that way, you can keep you var names. and that will work.
You can use "Array" (http://unity3d.com/support/documentation/ScriptReference/Array.html)
var vectorArray : Array = new Array();
function AddItem(item : Vector3)
{
vectorArray.Add(item);
}
Hi, I think this doesn't work. I'm running another function that will utilize the vectorArray[i] as a parameter. However, the parameter is set to a Vector3 type, and I think this type of array is just an Object type? Unity spits back: "The best overload for the method (..UnityEngine.Vector3)is not compatible with the argument list (..Object). Thanks for your help though!
Array is slow and not statically typed. List is much better.
