Events
The puzzles from this category handle user-generated events: mouse clicks / touches, hovering and dragging.

Puzzles Reference
when clicked
Waits until a user clicks on a specified 3D object (or any object in a specified list or group, or any object on the scene if the all objects puzzle is used) — then runs puzzles in the do slot.

If the enable "if missed" action checker enabled in the gear popup, additional if missed: do slot appears. The puzzles in this slot are triggered when the user clicks on some other object or on the background.

The advanced event options checker in the gear popup activates the following properties:

- x-ray
- Allow clicking the object behind any unclickable objects. Useful for clicking objects located behind semi-transparent surfaces or objects rendered above all (decalls or x-rayed geometries).
- double click / tap
- Execute puzzles in response to double click (desktops) or double tap events (mobiles).
- mouse buttons
- Execute puzzles only for the specified mouse buttons: left, middle, or right.
picked object
Returns an object a user has clicked on. Intended for use with the when clicked puzzle.

when hovered
Waits until a user hovers over/out a specified 3D object (or any object in a specified list or group, or any object on the scene if the all objects puzzle is used) — then runs puzzles in the over/out: do slot.

This puzzle works only on devices controlled by the mouse cursor, i.e. desktops and laptops. On touch screen devices it will do nothing.
The advanced event options checker in the gear popup activates the following property:
- x-ray
- Allow hovering behind other objects. Useful for outlining objects located behind semi-transparent surfaces or objects rendered above all (decalls or x-rayed geometries).
hovered object
Returns an object a user has hovered over. Intended for use with the when hovered puzzle.

This puzzle works only on devices controlled by the mouse cursor, i.e. desktops and laptops. On touch screen devices it will do nothing.
when moved
Tracks any movements (position, rotation and scale) of a specified object (or any object in a specified list or group, or any object on the scene if the all objects puzzle is used). Runs puzzles in the start: do slot if an object started moving, keeps running puzzles in the while moving: do slot until an object stops moving, then runs puzzles in the stop: do slot. The velocity parameter denotes a per-second change of any coordinate (x, y or z) of either of position, rotation or scale that is required to trigger this puzzle.

when dragged
Waits until a user drags over a specified 3D object (or any object in a specified list or group, or any object on the scene if the all objects puzzle is used) with the mouse or a touch gesture — then generates movement data for using in a drag move, drag rotate or drag scale puzzle.

The advanced event options checker in the gear popup activates the following properties:

- x-ray
- Allow dragging the object behind other objects. Useful for dragging objects located behind semi-transparent surfaces or objects rendered above all (decalls or x-rayed geometries).
- mouse buttons
- Drag only with the specified mouse buttons: left, middle, or right.
The enable start action and enable drop action checkers activate the corresponding slots used to capture the events of started and stopped dragging.

drag move
Moves a specified 3D object (or all objects in a specified list or group, or all objects on the scene if the all objects puzzle is used) in accordance to dragging movement data generated by the when dragged puzzle. Use the mode drop-down menu to limit the movement to a particular axis or plane, or set XYZ to move freely in all directions.

The use "space" option checker in the gear popup activates the space drop-down menu:

- world
- Perform movements in world coordinates, e.g. ignore any parent-child relations for the object. This mode is used by default.
- parent
- Perform movements relatively to the parent object.
- local
- Perform movements relatively to the object itself.
drag rotate
Rotates a specified 3D object (or all objects in a specified list or group, or all objects on the scene if the all objects puzzle is used) in accordance to dragging movement data generated by the when dragged puzzle. Use the mode drop-down menu to limit the rotation to a particular axis.

The use "space" option checker in the gear popup activates the space drop-down menu:

- world
- Perform rotations in world coordinates, e.g. ignore any parent-child relations for the object. This mode is used by default.
- parent
- Perform rotations relatively to the parent object.
- local
- Perform rotations relatively to the object itself.
drag scale
Scales a specified 3D object (or all objects in a specified list or group, or all objects on the scene if the all objects puzzle is used) in accordance to dragging movement data generated by the when dragged puzzle. Use the mode drop-down menu to limit scaling to a particular axis or set XYZ to scale the object uniformly.
