Events blocks

Use Events to decide when a script should begin. A game usually has several independent event stacks.

The built-in Events category starts with 6 core block shapes and is expanded by the larger generated catalog, so you can learn a small vocabulary before exploring specialized variants.

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.

When the project is materialized, supported Events 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.
