Appendix C — Cheat Sheet

Every Event and Action 8-Puzzle Solver uses, with what it does in one line, in Myth’s own words.

C.1 Events

Command Pressed
Runs once when the selected Button Command matches its Single, Double, or Triple Press pattern.
Create
Runs once when an instance is created.
Custom Event
Runs when another action or script triggers the selected named custom event.
Recurring Timer
Runs each time the named recurring timer comes due.
Scene Start
Runs when the scene starts.
UI Activated
Runs on this UI Object when the player activates its button or confirms one of its menu rows.

C.2 Actions

Change Component Value
Changes one mutable Object Component value through its direct path.
Change Sprite Tint Property
Changes exactly one persistent sprite-tint property while preserving every unrelated tint setting.
Change Variable
Changes one declared variable: a Local Variable of this Logic (private to this Logic Component, or to this call of a Function), a Per Instance Variable of the targeted Object (self.name), a Changeable Shared Variable (@self.name, @Guard.name: one value for every instance of that Object), or a Global.
Check Data Row Exists
Checks whether the Data Table has that row.
Control Data Row
Adds or updates one Data Table row, or removes it.
Control Tween
Stops, pauses or resumes running tweens: every tween of Applies To, the tweens of one value, or every tween with a Name.
Declare Variable
Brings a Local Variable into existence.
Else
Runs the Else action.
Generate Random Integer
Makes a whole number between Minimum and Maximum, including both endpoints, using the seeded gameplay random stream.
If
Runs its Then branch when its Condition is true.
Repeat
Runs its vertical child stack Count times.
Reset Data Table
Restores a Data Table to exactly what was authored in the editor, discarding every runtime change.
Return
Ends this run here.
Set Data Cell
Writes one cell of a Data Table row (the live game copy, not the authored resource).
Set Position
Moves the target immediately to a world position, an Object-local offset, a named Coordinate, or a Transform bounding-box anchor.
Start Recurring Timer
Starts or restarts one saveable named recurring timer.
Stop Recurring Timer
Stops one named recurring timer.
Switch Mode
Sets the Event to One at a time and turns on only the selected Mode.
Trigger Custom Event
Broadcasts one named Custom Event to matching Custom Event listeners.
Trigger Custom Event on Object
Sends one named Custom Event to the selected Object instance without broadcasting it to unrelated Objects.
Tween
Moves one value toward a target over time: any Number, Vec or Color of a Component (self.transform.position, self.transform.opacity, a light’s color, a Data Structure field) or a Variable.
While
Runs its vertical child stack while its Condition stays true.

C.3 Reading Values From Tables

data('table', row, 'column')
the value in one cell: the row by its name or number, the column by its name.
dataRow('table', number)
the name of the row at that number, counting from 0.
dataFind('table', 'column', value)
the number of the first row whose column holds this value.
dataCount('table')
how many rows the table has.
