Control blocks
Choose timing, loops and decisions. Control blocks decide the order in which work happens. They are how you wait, repeat, branch, broadcast and stop scripts.
What Control is for
Control blocks decide the order in which work happens. They are how you wait, repeat, branch, broadcast and stop scripts.
The built-in Control category starts with 9 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.
Place a Motion block inside Repeat.
Change the repeat count.
Try Wait so you can see each step happen.
How it becomes a real game
When the project is materialized, supported Control 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.
