🟩 Start

The Start block allows you to define the absolute launch point of any Graph, Scenario or Celestory Module. It represents the starting line of logical execution and is essential for the operation of each module.

Absolutely necessary, each module has only one Start block and can only start when activated.

📥 Entries

• No configurable input: This block is the origin point of the flow and cannot be the target of another block. It is triggered automatically by the system when a module is opened or the application initially loads.

📤 Outings

• Main flow (Stream): Original impulse of execution, allowing the Start block to be connected to the first logical or visual component of the chain.

💡 Example of use

Scenario: Initialization of a role-playing game

1. A new “Fantasy Adventure” module is created in Celestory.
2. The Start block is automatically placed on the design space.
3. A link is drawn from its output to an Assign block to initialize player variables (eg: life = 100, inventory = []).
4. The stream is then directed to a Scene block to display the game introduction.
5. The user sees the message: "You wake up in a mysterious forest..." and can begin to interact.

⚙️ Technical Details

• Uniqueness and persistence: This block is unique per module and cannot be accidentally deleted if it is at the heart of a graph.
• Visual anchor: Recommended as a reference point to facilitate rereading and maintenance of the graph.
