好吧,基本上我遇到的问题是,由于某种原因,GameObject 干扰了 OnPointerEnter 函数。我很确定 OnPointerEnter 只检测 UI。因此,当我看到本例中的特定 GameObject(即 PlayerLogic GameObject)(您可以在屏幕截图中看到)由于某种原因干扰 UI 元素的检测时,我感到非常困惑。我之所以相信它是这个特定的 GameObject 是因为一旦我执行了 PlayerLogic.SetActive(false); OnPointerEnter 再次开始工作,而且我也确信它不是 PlayerLogic 的任何子项,因为我已经尝试专门关闭它们,但它仍然不起作用。
PlayerLogic 对象的检查器
层次结构
我用来测试 OnPointerEnter 的代码
经过一些测试,我意识到具体问题出在 PlayerLogic 游戏对象上的玩家脚本中。现在让我困惑的是,一旦我关闭 Player 组件 OnPointer 就不起作用,但如果我从 PlayerLogic GameObject 中完全删除 Player 组件,OnPointerEnter 就可以工作。

这是 Player.cs 脚本。
我很确定 OnPointerEnter 只检测 UI。
没有。
它在 UI 上“开箱即用”,因为默认情况下每个
Canvas
都包含一个 GraphicsRaycaster
组件,然后由 EventSystem
使用和处理。
对于非 UI 3D 对象,您必须确保
IPointerXY
接口位于同一对象上Camera
上有一个 PhysicsRaycaster
组件对于非 UI 2D 对象非常相似
IPointerXY
接口位于同一对象上Camera
有一个 Physics2DRaycaster
组件请注意,任何其他对撞机或一般光线投射阻挡对象可能位于您的输入和目标对象之间,这也会阻止在您的对象上触发
OnPointerXY
。
CharacterController
只是一个胶囊形碰撞器 可以告诉它从脚本向某个方向移动。
这可能会阻塞输入。
现在输入您的
Player
代码:
你愿意
Cursor.lockState = CursorLockMode.Locked;
在
Awake
所以即使你事后将其关闭它也已经生效了。
