Question 1

In UMG Widget Blueprints, what is the correct way to play a named widget animation from Blueprint code?

Accepted Answer

Use the Play Animation node and pass the UWidgetAnimation variable

Answer

The 'Play Animation' node accepts a UWidgetAnimation reference (exposed as a variable when created in the Animations panel) and handles playback control.

Question 2

Which property on a Button widget controls whether it can receive click events from the player?

Accepted Answer

Is Enabled

Answer

'Is Enabled' determines whether the button responds to user input; a disabled button ignores clicks even when fully visible.

Question 3

What does the DPI Scaling curve in Project Settings → User Interface control for Widget Blueprints?

Accepted Answer

The factor by which UI elements are scaled based on screen resolution

Answer

The DPI Scaling curve maps screen resolution to a scale factor, so widgets appear at a consistent physical size across different resolutions and screen sizes.

Question 4

When would you use a 'Named Slot' in a User Widget Blueprint?

Accepted Answer

To define a placeholder that parent widgets can fill with custom child content

Answer

Named Slots act as content injection points in a reusable widget, letting the widget's user (parent) insert their own child widgets into predefined locations.

Question 5

Which approach correctly detects when the mouse cursor enters a custom widget area in a Widget Blueprint?

Accepted Answer

Override the On Mouse Enter event in the Widget Blueprint's Event Graph

Answer

Widget Blueprints expose overridable events like 'On Mouse Enter' that fire when the cursor enters the widget's bounding box.
