why is it that my script only works when i drag it on play into the game object?
it previously worked but i had to drag a material into the inspector to set it. i thought it would be neat to just set it in code rather than dragging and dropping. after some research i found a way, but it now will only spawn the cube when i drag the script into the gameobject on play.

using UnityEngine;
using System.Collections;

//GameObject Cube = new GameObject();

i removed this
public Material Red = Resources.Load("Red",typeof(Material)) as Material;
changing this
GetComponent<MeshRenderer>().material = Red;
to this
GetComponent<MeshRenderer>().material = Resources.Load("Red",typeof(Material)) as Material;
and it fixed my problem. Thank you for your reply, I did try it but it did not load the material on the cube. same as my problem was unless i went and dragged it on inspector every play. and at one point the cube was not appearing unless i added it during play. so i created awake function added everything into awake than added awake(); into the start function.
That's what i suggested... "Resources load needs to be in a function. Try moving it to Awake or Start"
Do you get an error? The console should be outputting:
ArgumentException: Load can only be called from the main thread.
Constructors and field initializers will be executed from the loading thread when loading a scene
Don't use this function in the constructor or field initializers, instead move initialization code to the Awake or Start function.
It's referring the material:
public Material Red = Resources.Load("Red",typeof(Material)) as Material;
Resources load needs to be in a function. Try moving it to Awake or Start:
public Material Red;
void Awake () {
if (Red == null) Red = Resources.Load("Red",typeof(Material)) as Material;
}
