Controls

  • Drag a machine onto the canvas
  • Drag empty space to pan, scroll to zoom
  • Drag between port disks to connect
  • Drag from one input (or output) to another on the same machine to swap their places
  • Drag an input port onto an empty machine to make it produce that item
  • Scroll over a node to change its count (a Constraint: its value)
  • A Junction passes flow straight through: use it to bend a belt's route or to join and split belts
  • Press L, then draw around buildings to select them (drag one to move the group, S toggles solving)
  • Ctrl+C copies the selection, Ctrl+V places a copy
  • Drop a module onto a building (Shift fills every slot); click a module to remove it
  • Shift+right-click a building copies its modules, Shift+click applies them
  • Press W over a node or belt to watch it (pinned top right)
  • Over a Constraint: < at most, > at least, M maximise
  • Press S over a machine or constraint to let the solver choose its count or value (?, orange)
  • Drop a building onto a compatible one to swap its type
  • x over a node or edge deletes it
Drag a machine from the panel onto the canvas to begin.
Then click its gear to choose a recipe.
