I'm trying to create a function were I cast to a Widget in order to change a progress bar, but I can't figure out how to reference the Widget from another blueprint. I can create the reference, but I can't find a way to actually create the reference: https://imgur.com/a/9qutKzw. So just to understand, you have a widget and you want to get. WidgetComponent中使用Screen模式能将widget转移至slate层，但处于视口创建的UMG层级之下，导致WidgetComponent中UMG层级不能高于视口UMG。说明:WidgetComponent创建UMG会添加进SWorldWidgetScreenLayer，不同的sharedlayer会存进不同的SWorldWidgetScreenLayer，这些layer默认都在视口UMG层级之下，做法一是自己在WorldWidgetScreenLayer之下.

This is very basic BP, but I generalized a common operation to one function node. Here we insert any actor class and return the nearest of that type to the player. Maybe there are better ways, but it's good to have a single node to poll for actors. This is the kind of function you might put in a FunctionLibrary so you can get it from any BP. Click the Add Component button, then find and select the Widget option What is the Actor Component and how do we use it in Unreal Engine 4Source Files: https://github cs file and include the plugin in the Public Dependency Modules: PublicDependencyModuleNames However, since it’s a scene component, we can add child components to it Click on Components Click on.
