我只是想用鼠標(biāo)拖動(dòng)來(lái)移動(dòng)對(duì)象。對(duì)象是父對(duì)象的子對(duì)象。這就是代碼中使用 localPosition 的原因。Vector3 startPos;Vector3 dist;void OnMouseDown(){ startPos = Camera.main.WorldToScreenPoint(transform.localPosition); dist = transform.localPosition - Camera.main.ScreenToWorldPoint(new Vector3(Input.mousePosition.x, Input.mousePosition.y, startPos.z));}void OnMouseDrag(){ Vector3 lastPos = new Vector3(Input.mousePosition.x, Input.mousePosition.y, startPos.z); transform.localPosition = Camera.main.ScreenToWorldPoint(lastPos) + dist;}預(yù)期在 x&z 軸上移動(dòng)對(duì)象，但在 x&y 上移動(dòng)。

您需要翻轉(zhuǎn)它，以便使用 Input.mousePosition.y 作為 z 軸，使用 startPos 作為 y 軸。這應(yīng)該有效：
public class MovementController : MonoBehaviour
{
private const float planeY = 0f;
Plane plane = new Plane(Vector3.up, Vector3.up * planeY); // ground plane
void OnMouseDrag()
{
Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
float distance; // the distance from the ray origin to the ray intersection of the plane
if(plane.Raycast(ray, out distance))
{
transform.position = ray.GetPoint(distance); // distance along the ray
}
}
}
