Appendix C — Cheat Sheet

Every Event and Action Crystal Cascade uses, with what it does in one line, in Myth’s own words.

C.1 Events

2D Direction Pressed: Runs once when the selected Left, Right, Up, or Down direction is pressed.
Command Pressed: Runs once when the selected Button Command matches its Single, Double, or Triple Press pattern.
Command Released: Runs once when the selected Button Command is released.
Create: Runs once when an instance is created.
Custom Event: Runs when another action or script triggers the selected named custom event.
Leave View: Runs once when this instance leaves all active camera views.
Mouse Enter: Runs when the pointer enters this instance.
Mouse Press: Runs once when the selected mouse button is newly pressed anywhere in the game view.
Mouse Pressed on Object: Runs once when a mouse button is newly pressed over this instance.
Recurring Timer: Runs each time the named recurring timer comes due.
Scene Start: Runs when the scene starts.

C.2 Actions

Burst Particles: Emits a one-shot Particle effect at the Object origin, a named Coordinate, a bounding-box anchor, or an explicit world position.
Camera Flash: Flashes one camera view with a transient color veil that fades from opaque to clear.
Camera Shake: Shakes the camera — impacts, explosions, spells.
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 Game State: Runs nested actions while the singular project Game State matches the selected value.
Control Data Row: Adds or updates one Data Table row, or removes it.
Control Sound: Plays, loops, crossfades, or stops one selected Sound resource.
Control Tween: Stops, pauses or resumes running tweens: every tween of Applies To, the tweens of one value, or every tween with a Name.
Create Instance: Creates one instance at world XYZ, Self-relative XYZ, or an exact named Coordinate, optionally with a starting rotation, scale and launch speed, and names it (Variable Name).
Declare Variable: Brings a Local Variable into existence.
Destroy Instance: Destroys the selected target: Self, Event other, or all live instances of a named Object.
Else: Runs the Else action.
End Game: Ends the current game, fires Game End once, and releases the running scene.
Generate Random Integer: Makes a whole number between Minimum and Maximum, including both endpoints, using the seeded gameplay random stream.
Generate Random Number: Makes a decimal number between Minimum and Maximum using the seeded gameplay random stream.
Go to Scene: Goes to one selected scene, optionally fading or crossfading.
If: Runs its Then branch when its Condition is true.
Load Persistent Value: Reads a device-persisted value, or the Default if none is stored yet, and publishes one typed Action result.
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.
Restart Scene: Restarts the current scene without restarting the complete game run.
Return: Ends this run here.
Save Persistent Value: Writes one device-persistent value under one title-scoped key.
Set Alpha: Sets alpha for the target or game.
Set Data Cell: Writes one cell of a Data Table row (the live game copy, not the authored resource).
Set Frame: Sets frame for the target or game.
Set Game Paused: Pauses or resumes the whole simulation.
Set Game State: Changes the singular project-wide Game State and runs Game State Changed when the value changes.
Set Input Context Active: Activates or deactivates one Input Context without changing any other active contexts.
Set Logic State: Enables, disables, or toggles one attached Logic on each target instance, firing lifecycle events only for real state transitions.
Set Position: Moves the target immediately to a world position, an Object-local offset, a named Coordinate, or a Transform bounding-box anchor.
Set Scale: Sets the Object instance’s live size multipliers.
Set Spin: Sets how fast the object is turning, in degrees per second.
Set Velocity: Sets the exact horizontal velocity, vertical velocity, or both.
Set Visible: Sets visible for the target or game.
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.
dataFind('table', 'column', value): the number of the first row whose column holds this value.
dataCount('table'): how many rows the table has.
