Question 1

How to create a custom widget in LUIS?

Accepted Answer

Create a Lua file in the widgets directory, define new(), update(), draw(), and click() functions, and use setluis() to access the core library, as outlined in the Custom Widgets section of the README.

Question 2

Does LUIS support touch input for mobile games?

Accepted Answer

Yes, LUIS has built-in support for touch interactions alongside mouse and keyboard, but since it's built on Löve2D, mobile deployment depends on Löve2D's platform support and may require additional setup.

Question 3

LUIS vs SUIT for Love2D UI?

Accepted Answer

LUIS offers a grid-based layout and modular widgets with zero-dependency core, while SUIT is simpler but less flexible. Choose LUIS for complex, customizable UIs and SUIT for quicker, basic interfaces.

Question 4

How to add animations to LUIS widgets?

Accepted Answer

Use the flux library integrated in LUIS, as shown in the example where luis.flux is required and updated in love.update() to handle animations for widgets like DialogueBox.

Question 5

What are the known issues with LUIS gamepad support?

Accepted Answer

The README lists problems like DropBox selection and FlexContainer dropdown navigation not working with gamepad analog sticks, so test thoroughly if your game relies on controller input.

Question 6

Can I use LUIS without the pre-built widgets?

Accepted Answer

Yes, the core library has zero dependencies and can be used alone to implement custom widgets, making it lightweight for tailored UI needs, as mentioned in the features note.
