精灵自动定位和缩放

我有4个带有碰撞器的子画面，我想自动调整位置并将它们均匀缩放到屏幕底部，这样它们就不会越过圈并且完全不在屏幕之外。我不能在画布上做到这一点，它需要作为gameObjects完成。

我还试图根据外观将每个Sprits高度设置为1 / 4th-1 / 5th，这就是为什么代码在下面被4除。

如何使它们并排放置在底部？

public class AutoPosition : MonoBehaviour {

public Sprite [] goals;

public float width = Screen.width / 4;
public float height = Screen.height / 4;
// Use this for initialization
void Start () {
    for (int i = 0; i < goals.Length; i++) {
        goals[i]
    }
}

您可以将SpriteRender用于图像。并将它们放置在父母内部GameObject。仅简单地GameObject正确缩放和定位一个父对象就足够了（类似于画布，但具有常规Transform组件）。

public class applySize : MonoBehaviour 
{
    private void Apply()
    {
        // Get the main camera position
        var cameraPosition = Camera.main.transform.position;

        // This makes the parent GameObject "fit the screen size"
        float height;
        if (Camera.main.orthographic)
        {
            // Camera projection is orthographic
            height = 2 * Camera.main.orthographicSize;
        }
        else
        {
            // Camera projection is perspective
            height = 2 * Mathf.Tan(0.5f * Camera.main.fieldOfView * Mathf.Deg2Rad) * Mathf.Abs(cameraPosition.z - transform.position.z);
        }

        var width = height * Camera.main.aspect;

        transform.localScale = new Vector3(width, height,1);
        transform.position = cameraPosition - new Vector3(0,height*.375f, cameraPosition.z);

        // Since the 4 images are childs of the parent GameObject there is no need
        // place or scale them separate. It is all done with placing this parent object
    }

    private void Start()
    {
        Apply();
    }
}
