Ui blocks
Create buttons, labels and inputs. UI blocks create interface elements that sit on top of the game so you can build menus and controls visually.
What Ui is for
UI blocks create interface elements that sit on top of the game so you can build menus and controls visually.
The built-in Ui category starts with 5 core block shapes and is expanded by the larger generated catalog, so you can learn a small vocabulary before exploring specialized variants.
Core blocks you will see
These names come from the current RC Blocks Studio catalog. Start with the first two or three and ignore the rest until your project needs them.

Build the smallest possible experiment so you can see what this category changes.
Create a label or button with a clear id.
Change its text from another block.
Remove it when the scene ends.
How it becomes a real game
When the project is materialized, supported Ui opcodes are compiled into the generated browser runtime rather than remaining visual-only editor decorations.
That means the same block idea can affect the full RC project when you Save and Run project.
