Studio State Machine
The set must always know its one current mode. Build safe paths between rehearsal, filming, pauses, and the final wrap—without letting impossible jumps spoil the production.
🧠 Before we start
In the Jungle Footprint Filter, tiny memory answered questions about what may have happened. Today, a finite-state machine remembers exactly one current mode. An event may move it only along an allowed transition.
Build the production path
Tap the next states in a legal order. A shoot cannot wrap before filming has started.
Direct events at the live set
The same event can be allowed in one state and ignored in another. Send the call sheet in order: start, pause, resume, finish.
Add a readiness guard
An allowed arrow can still wait for a safety rule. Turn on both readiness checks before asking the machine to enter Filming.
Debug the missing premiere path
Editing is complete, but the state machine has no legal way to reach Premiere. Repair the model without deleting its safety rules.
🌟 What you learned
- A finite-state machine remembers one current state.
- Events request movement from one state to another.
- Transitions define which movements are allowed.
- The same event may be valid in one state and rejected in another.
- Guards allow a transition only when required conditions are ready.
- Explicit states and transitions prevent impossible combinations and make behavior easier to debug.
