Instantiate PreFab with C# Script

Question

Hi,

I've found online that the best way to instantiate a game object type is with the following statement:

GameObject go = Instantiate(Resources.Load("MyPrefab"));

This does not work for me, does it require more using statements than:

using UnityEngine; using System;

I am getting the following error:

Assets/Scripts/Instantiate.cs(54,67): error CS0426: The nested type Load' does not exist in the typeUnityEngine.Resources'

you can create any public variable type that is a children of component or GameObject and instantiate it with this function. the return type of Instantiate is UnityEngine.Object and you should cast it if you want to asign it to a variable of type GameObject. so just (GameObject) before the Instantiate and it will work well. you should have the resources folder with the prefab in it thow.

GameObject go = (GameObject)Instantiate(Resources.Load("MyPrefab")); ;

or

GameObject go = Instantiate(Resources.Load("MyPrefab")) as GameObject;

see MSDN topics for as keyword and topics about casting for more information.

the faster way is to make a public variable for the Prefab and drag your Prefab on it in the inspector and then instatiate it. Resources.Load is really slow, so you should avoid it, if you can.

 public GameObject myPrefab;
 
 GameObject go = (GameObject)Instantiate(myPrefab);

In the root of your Project hierarchy make a folder called 'Resources', put your prefab in that folder. My prefab is called DamageText and here is my working code:

GameObject textObject = (GameObject)Instantiate(Resources.Load("DamageText"));

Tested using C# with Unity 2.6.

this is the actual correct answer. Resource.Load looks in a resource folder to find the object you want to load. The error message tells you this as well (in a very confusing way):

Assets/Scripts/Instantiate.cs(54,67): error CS0426: The nested type Load' does not exist in the typeUnityEngine.Resources'

Resource.Load also works if the Resource-Folder is not on top of your Project or Asset dir, it can by within any subdirectory if you want, i.e. Assets/Prefabs/Weapons/Resources/myPrefab is perfectly fine.

This is what I would do

at the top put

public Transform whatYouWantToInstantiate;

then wherever you want to instantiate

Instantiate(whatYouWantToInstantiate);

That's the simple way...

This way work for a transform varaible, but I need to instantiate a prefab. Sorry I left that unspecified.

it should work the same - you can just drag the prefab onto the transform variable

That's because you are creating a new GameObject called "go" and you are making that gameObject by instantiating. The reason it says thatb it's never used because you probably don't have anything like go.GetComponent or any other thing that you want to do with go, therefor it's assigned but you didn't use that assignment... If you get what I mean

I found a video explaining this pretty good if you still need help, also tells you how to spawn a rigidbody: https://www.youtube.com/watch?v=_Xrw2EEhzI4
