我如何修改DrawEx函数来适配unity

[Amyas]

public void DrawEx(Texture2D Texture, float X, float Y, int OriginX, int OriginY, float ScaleX, float ScaleY, float Rotation,
    bool FlipX, bool FlipY, byte Red, byte Green, byte Blue, byte Alpha, bool DoCenter, BlendMode BlendMode = BlendMode.Normal)
{
    SetBlendMode(BlendMode);
    SpriteEffects Flip = SetFlip(FlipX, FlipY);
    if (DoCenter)
    {
        OriginX = Texture.Width / 2;
        OriginY = Texture.Height / 2;
    }

    SpriteBatch.Draw(Texture,
                  new Vector2(X, Y),
                  null,
                  new Microsoft.Xna.Framework.Color(Red, Green, Blue, Alpha),
                  Rotation,
                  new Vector2(OriginX, OriginY),
                  new Vector2(ScaleX, ScaleY),
                  Flip,
                  0);

    SpriteBatch.End();
}
请问我如何使用unity 创建里面的内容坐标
            if (DoCenter)
        {
            originX = texture.width / 2;
            originY = texture.height / 2;
        }

        UnityEngine.Sprite newSprite = UnityEngine.Sprite.Create(
            texture,
            new UnityEngine.Rect(0, 0, texture.width, texture.height),
            Vector2.zero,
            100f,
            0U,
            SpriteMeshType.FullRect
        );
        Transform transform = Utils.CreateImageNode(this.transform, "bs_" + index++).transform;
        RectTransform rectTransform = transform as RectTransform;
        rectTransform.anchoredPosition = new Vector2(x, y);
        Image image = transform.GetComponent<Image>();
        image.sprite = newSprite;
        image.SetNativeSize();
        
        我这样写，坐标对不上ui
