控件交互组件 如您使用控件组件显示以 3D 形式存在于游戏世界中的 UI,还需要玩家与此控件进行交互,可通过控件交互(Widget Interaction)组件来实现交互。 控件交互组件执行光线投射,确定它是否命中世界场景中的控件组件。如命中,可设置规则确定与其交互的方式。 交互通过模拟定义的按键来执行。例如一个按钮可通过...
This is a component to allow interaction with the Widget Component. This class allows you to simulate a sort of laser pointer device, when it hovers over widgets it will send the basic signals to show as if the mouse were moving on top of it. You’ll then tell the component to simulate...
When standard input comes to the player controller, you’ll instruct the interaction component to simulate a particular hardware input such as Left Mouse Down/Up over whatever widget the user happens to be hovering at that time.For users who were previously relying on clicking directly on Widget ...

它們的名稱為 OpenXRMsftHandInteraction Select 和 Grip 對應。 您不需要啟用訂用帳戶,您應該在 Project 設定/Engine/Input 中宣告事件,如下所示: 下一個開發檢查點 依循我們配置的 Unreal 開發旅程,此時您會探索 MRTK核心建置組塊。 接下來,您可以繼續進行下一個建置組塊: 本機空間錨點 或者,直接跳到混合實境...
你可以在对象的GrabComponent中设置OnGrabHaptic效果变量,定义抓取对象时的触觉效果。触觉效果的示例包括运动控制器振动。 GrabComponent中使用的重要函数抽象为使用蓝图接口资产VRInteraction BPI的通用接口。借助此蓝图接口资产,VRPawn可以简化逻辑,避免对每种类型的对象进行多次检查。有关蓝图接口及其优势的更多...
Actors包含大量函数和变量,它们是Unreal Engine中gameplay framework的基石,因此不要对此感到惊讶。进一步学习该类的方法,就是打开Actor.h文件。 ActorComponent Components存活于Actor内,常见的Components包括StaticMeshComponent,CharacterMovementComponent,CameraComponent和SphereComponent。这些Components每个完成特定的任务,例如move...
