Class: oColumn

// You can get the entirety of the columns in the scene by calling:
var doc = $.scn;
var allColumns = doc.columns;

// However, to get a specific column, you can retrieve it from its linked attribute:

var myAttribute = doc.nodes[0].attributes.position.x
var mycolumn = myAttribute.column;

// once you have the column, you can do things like remove duplicates keys to simplify an animation;
myColumn.removeDuplicateKeys();

// you can extract all the keys to be able to iterate over it:
var keyFrames = myColumn.getKeyFrames();

for (var i in keyFrames){
  $.log (keyFrames[i].frameNumber);
}

// you can also link a given column to more than one attribute so they share the same animated values:

doc.nodes[0].attributes.position.y.column = myColumn;  // now position.x and position.y will share the same animation on the node.

Members

readonlyframesArray.<$.oFrame>

An array of the oFrame objects provided by the column.

readonlykeyframesArray.<$.oFrame>

An array of the keyframes provided by the column.

namestring

The name of the column.

selectedbool

Whether the column is selected.

stepSectionobject

An object with three int values : start, end and step, representing the value of the stepped section parameter (interpolation with non linear "step" parameter).

readonlysubColumnsobject

Provides the available subcolumns, based on the type of the column.

readonlysubColumnsobject

The type of easing used by the column

readonlytypestring

The type of the column. There are nine column types: drawing (DRAWING), sound (SOUND), 3D Path (3DPATH), Bezier Curve (BEZIER), Ease Curve (EASE), Expression (EXPR), Timing (TIMING) for timing columns, Quaternion path (QUATERNIONPATH) for 3D rotation and Annotation (ANNOTATION) for annotation columns.

Methods

duplicate(newAttribute){$.oColumn}

openHarmony/openHarmony_column.js, line 336

Duplicates a column. Because of the way Harmony works, specifying an attribute the column will be connected to ensures higher value fidelity between the original and the copy.

Name	Type	Description
newAttribute	$.oAttribute	optional An attribute to link the column to upon duplication.

Returns:

Type	Description
$.oColumn	The column generated.

extendExposures(exposures, amount, replace)

openHarmony/openHarmony_column.js, line 278

Extends the exposure of the drawing's keyframes given the provided arguments.

Name	Type	Description
exposures	Array.<$.oFrame>	The exposures to extend. If UNDEFINED, extends all keyframes.
amount	int	The amount to extend.
replace	bool	Setting this to false will insert frames as opposed to overwrite existing ones.

Deprecated

• Use oDrawingColumn.extendExposures instead.

getKeyframes(){Array.<$.oFrame>}

openHarmony/openHarmony_column.js, line 376

Filters out only the keyframes from the frames array.

Returns:

Type	Description
Array.<$.oFrame>	Provides the array of frames from the column.

getKeyFrames(){Array.<$.oFrame>}

openHarmony/openHarmony_column.js, line 404

Filters out only the keyframes from the frames array.

Deprecated

• For case consistency, keyframe will never have a capital F

Returns:

Type	Description
Array.<$.oFrame>	Provides the array of frames from the column.

getTimelineLayer(timeline){int}

openHarmony/openHarmony_column.js, line 468

Retrieves the nodes index in the timeline provided.

Name	Type	Description
timeline	oTimeline	optional Optional: the timeline object to search the column Layer. (by default, grabs the current timeline)

Returns:

Type	Description
int	The index within that timeline.

getValue(frame){various}

openHarmony/openHarmony_column.js, line 415

Gets the value of the column at the given frame.

Name	Type	Default	Description
frame	int	1	optional The frame at which to get the value

Returns:

Type	Description
various	The value of the column, can be different types depending on column type.

interpolateValueAtFrame(percentage, frameNumber)

openHarmony/openHarmony_column.js, line 496

Create/Set a key at the given percentage between the surrounding keys. Requires the column to contain at least 2 keys.

Name	Type	Description
percentage	int	a value between 0 and 100 representing the position between first and second key
frameNumber	int	the frame number to place the new value.

Example

// grab the current node and create a key at the current frame halfway between existing keys on all linked columns for this node.
var selectedNode = $.scn.selectedNodes[0];
var columns = _node.linkedColumns;
var percentage = 50;
var frameNumber = $.scn.currentFrame();

for (var i in columns){
  try{
	   columns[i].interpolateValueAtFrame(percentage, frameNumber); // ommitting the arguments will create a key at 50% on current frame by default.
  }catch(e){
    // will output errors for columns with less than 2 keys or which type don't support interpolation (for ex, DRAWING)
    $.log(e);
  }
}

remove()

openHarmony/openHarmony_column.js, line 265

Deletes the column from the scene. The column must be unlinked from any attribute first.

removeDuplicateKeys()

openHarmony/openHarmony_column.js, line 294

Removes concurrent/duplicate keys from drawing layers.

setValue(newValue, frame)

openHarmony/openHarmony_column.js, line 440

Sets the value of the column at the given frame.

Name	Type	Default	Description
newValue	various		The new value to set the column to
frame	int	1	optional The frame at which to get the value
