关于仓库栏的设置,物体如何进入仓库内容【查看此篇】
能够被获取的物体,必须需要是一个碰撞体,即绑定了碰撞体组件。
Mouse3D需要绑定对应的脚本。
脚本部分
public class Mouse3D : MonoBehaviour
{public static Mouse3D Instance { get; private set; }[SerializeField] private LayerMask mouseColliderLayerMask = new LayerMask();private void Awake(){Instance = this;}private void Update(){Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);if (Physics.Raycast(ray, out RaycastHit raycastHit, 999f, mouseColliderLayerMask)){transform.position = raycastHit.point;}}public static Vector3 GetMouseWorldPosition() => Instance.GetMouseWorldPosition_Instance();public static Transform GetClickedTransform() => Instance.GetClickedTransform_Instance();private Vector3 GetMouseWorldPosition_Instance(){Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);if (Physics.Raycast(ray, out RaycastHit raycastHit, 999f, mouseColliderLayerMask)){return raycastHit.point;}else{return Vector3.zero;}}private Transform GetClickedTransform_Instance() {Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);if (Physics.Raycast(ray, out RaycastHit raycastHit, 999f, mouseColliderLayerMask)){return raycastHit.collider.transform;}else{return null;}}}
