Instantiate a spine object by script

abken601

Hi, I am super new in using Spine in Unity. I have a question of instantiating a spine game object through script.

I have an Spineboy object downloaded from the tutorial. It works very well.
Then I drag Spineboy to "Resources" folder ( to instantiate prefabs via scripts, the prefabs have to be put in the "Resources folder".

As usual, I instantiate Spineboy via script.
private GameObject spineboy;
spineboy = GameObject.Instantiate (Resources.Load ("Spineboy")) as GameObject;

I received a complaint from the debug log
ArgumentException: The Object you want to instantiate is null.

May another help me thanks!!

Are you also new to Unity?

You can instantiate a new GameObject with a SkeletonAnimation on it from a given SkeletonData asset by making this call

var newSkeletonAnimation = SkeletonAnimation.NewSkeletonAnimationGameObject(yourSkeletonDataAsset);

Yes, I am new to Unity too.

Thanks for your prompt reply. However, I still cannot have the problem fixed.

If I put the SkeletonData Asset into the "Resources" folder, how can I instantiate it via script.

Thanks.

var yourSkeletonDataAsset = Resources.Load<SkeletonDataAsset>("spineboy/spineboy_SkeletonData");
var newSkeletonAnimation = SkeletonAnimation.NewSkeletonAnimationGameObject(yourSkeletonDataAsset);

But Unity doesn't recommend using the Resources folder anymore, unless it's for prototyping. And even then, it's not really that helpful.

You can learn more here: https://unity3d.com/learn/tutorials/topics/best-practices/resources-folder
I do encourage you to go through Unity's official tutorials especially if you're new to it, even if you know some of it already.

Thank you Pharan!

It is an interesting issue of using Resources folder. I was told to do so because my game consists of hundreds of character but
only a few of them are used in the gameplay, depending upon which levels the player chooses to play. In this case, I could not
load hundreds of characters when the player enters the game scene. Therefore I chose to load the characters via scripts. I do not
know what other methods are better than that.
