The current mouse position delta in pixel coordinates. (Read Only). Input.mousePositionDelta is a Vector3 for compatibility with functions that have Vector3 arguments.

2019年3月18日 · Mouse input became jittery and felt out-of-sync with my mouse movements. After finding this thread I tried changing from using an action callback to Mouse.current.delta.ReadValue() but it doesn’t appear to have resolved the problem.

在最新版本的Unity Input System中，鼠标的delta值可以通过 Mouse.current.delta.ReadValue() 来获取。以下是一个完整的示例代码，展示如何使用鼠标的delta值来控制摄像机：

2025年1月23日 · print (Mouse. current. delta. ReadValue ()); // 获取鼠标滚轮的滚动量，返回一个Vector2，通常只关心Y分量： // - 向上滚动时，Y值为正值； // - 向下滚动时，Y值为负值； // X分量通常用于侧向滚动（某些鼠标支持），但不常见。 print (Mouse. current. scroll. ReadValue ()); …

2023年9月6日 · Mouse. current 鼠标指针位置(屏幕空间) mouse. position. ReadValue 类似Input. mousePosition ... mouse. delta. ReadValue 鼠标移动增量 类似 Mouse X 和Mouse Y的组合 :: 心前阳光 ...

Use this to distinguish double- or multi-clicks. The input from the mouse scrolling control expressed as a delta in pixels since the last frame. Can come from a physical scroll wheel, or from touchpad gestures. On desktop platforms (Windows, Mac, Linux, and UWP), you can move the mouse cursor via code.

2020年12月17日 · I've tried replacing Delta [Mouse] with Position [Mouse] but then the value is limited to screen width. Does anyone know what I can do? Also, I'm using. Vector2 movementInput = playerInput.Player.View.ReadValue<Vector2> (); ~Bla Bla~ orientation.rotation = Quaternion.Euler (desiredView * Time.deltaTime);

GetMouseDelta returns the current change in movement of the mouse as a Vector2, but only if the mouse is locked. If the mouse isn't locked the values in the returned Vector2 will be zero. It measures any mouse movement in pixels from the last render step to the current render step.

2010年9月19日 · That is how you get the mouse delta, assuming Mouse X and Mouse Y are set to mouse movement in the input manager, and it works fine here. It doesn’t return the actual mouse position (that’s what Input.mousePosition is for).

Input.mouseScrollDelta 存储在 Vector2.y 属性中。 （Vector2.x 值将被忽略。 ） Input.mouseScrollDelta 可以是正数（向上）或负数（向下）。 未旋转鼠标滚轮时，该值为零。 注意，PC 上一般采用带有中心滚轮的鼠标。 新版 macOS 在触控板上通过双指上下移动来模拟中心滚动。 需要根据滚动速率，调整 mouseScrollDelta 返回的值。 下面的示例中，使用了 0.1f 的 scale。 注意， mouseScrollDelta 为只读。 // slide on a Mac trackpad. private Transform …
