No-code workspace: block, region, and result flow
On scan blocks such as IMAGE, the user manages the target image, scan region, and true/false branches.

- 1First inspect the target image and selected scan engine on the block card.
- 2Keep the scan region as tight as possible; wide regions reduce performance and accuracy.
- 3Treat TRUE and FALSE branches separately: action on found, wait or fallback flow on not found.
What is taught? Adding blocks, scan regions, tapping the last hit, and fallback branch logic.
In complex scenarios, IMAGE, COLOR, TEXT, and MOVING COLOR blocks should follow the same tight-region and controlled-timeout discipline.
