在Unity中设置Sprite的位置

Question

I want to set the position of a Sprite via Script but i cant use

gameObj.transform.localPosition = new Vector3(0,0,0);

somehow.

it gives me the error "Sprite does not contain a definition for transform and no accesible extension method transform accepting a first argument of type Sprie could be found..."

Answer 1

Setting a game object's position is the same as setting the sprite positions.
(Included the fact that the sprite is a component of the game object)

// Moves the entire gameobject. (Aka moving the 'sprite' in the gameobject along with it)    
gameObject.transform.localPosition = new Vector3(0,0,0);

Your error occured due to the fact that gameObj is a type Sprite , and Sprite don't have transforms. Its game objects that have it.

Edit

If you wanted to move the 'sprite' of a game-object only, make a child gameobject that hosts the sprite-renderer instead, and move the child by itself, like so:

And your inspector for ObjectWithSprite should look similar to:

Of course, replacing MovingGameObject script with your intended script that will control the movement of the sprite of the gameobject:

public class MovingGameObject : MonoBehaviour {
    void Update() {
        // Or some other location;
        gameObject.transform.position = Vector3.zero;
    }
}

Answer 2

It seems your gameObj is a sprite not GameObject , if you want to handle the gameObject

You can use public variable to assign the gameObject of sprite in Inspector

public GameObject gameObj;  

and your method to set position works now.

gameObj.transform.localPosition = new Vector3(0,0,0);

if you want to access the properties of sprite, you can use GetComponent

Debug.Log(gameObj.GetComponent<Sprite>().pivot); 

Maybe you should also check SpriteRenderer
