在ProjectSetting中勾选UseMouseForTouch。Touch就是手机、平板等设备的触屏功能。没错这些带滚动条的组件是支持触屏滚动的,所以只要把鼠标模拟Touch选上就行。勾上以后屏幕会出现一个很丑的虚拟摇杆,把DefaultTouchInterface设为空即可。 方法2: 调用SetScrollOffset函数可以设置滚动条偏移。然后检测鼠标是否在UI上,再...
下面以UserWidget为例,看一下它的TouchStart事件在PC上的调用流程(勾选UseMouseForTouch的情况)。 首先是平台层,根据不同的硬件设备和操作系统调用不同平台的API。window平台调用的是WindowsApplication类。在这个类里面会接受玩家输入,判断玩家输入类型,最终来到Slate层的SlateApplication的OnMouseDown并且传入玩家输入相关...
上面有提到,就是在某些时候(按下Start)锁定某个Slate,方便后续一些操作(如拖拽)使用 模拟触摸(Faking Touch) 在ue4里,鼠标点击和Touch(移动设备的触屏)是两种不同的操作。为了在编辑器下模拟Touch,通常会勾选ProjectSettings里的UseMouseForTouch。这个情况下要想判断是真正的Touch还是模拟的Touch,可以调用FSlateApplic...

This becomes a natural place to put the code that “does things”, for example on a mouse event you might directly apply a brush stamp in a painting tool. Seems harmless until users ask for support for other input devices, like touch, or pen, or VR controllers. Now what? Do you just...
Thanks for your prior, which answered me. UE4.27 and different subject: I investigated and see that you are using a Look at - to detect the possession event. But I have a 3D SideScroller project (currently without mouse control), and I want to use Player next to Car (collision box) ...
