The Action Logic Builder

The Action Logic Builder is where you write the logic for a step as visual cards. Open it from a node’s Logic tab: the inline editor gives you two ways in, Compose for the card builder and Open Editor for the full code editor. Both produce the same logic, and you can switch between them.

Building with cards

The card builder lays your logic out as a list of steps. Click Add Action to pick from a searchable, categorized menu, grouped by variables, attributes, resources, time, control flow, entities, and system actions, then fill in each card’s fields. Ready-made templates sit at the top of the menu for common shapes such as get a resource, process for a time, then release. Container cards such as If and While hold other cards inside them, and you can drag cards to reorder, duplicate, or disable them. The Send Entity card creates an entity elsewhere in the model and takes a quantity, so one card can dispatch several at once (see Send).

Moving between cards and code

A Show Code toggle displays the generated code beside the cards. The code is the single source of truth: the cards are a view of it, so anything written in code opens correctly as cards and the other way round. For the full writing surface, with suggestions, checking as you type, and inserts for distributions and process tables, open the code editor.
