Cel

A cel is an image at a specific xy-coordinate, and a specific layer/frame combination.

Cel.sprite

local sprite = cel.sprite

Cels belong to one sprite. This property returns that sprite.

Cel.layer

local layer = cel.layer

Returns the layer where this cel is located.

Cel.frame

local frame = cel.frame
cel.frame = newFrame

Returns the frame object to which this cel belongs. If you set this property, the cel will be moved to the given frame (if another cel already exists in that frame, it will be removed).

Cel.frameNumber

local frameNumber = cel.frameNumber
cel.frameNumber = newFrameNumber

Returns the frame number to which this cel belongs. The frame number 1 is the first frame (not 0). If you set this property, the cel will be moved to the given frameNumber. Check the notes of Cel.frame.

Cel.image

local image = cel.image
cel.image = newImage

Gets or sets the image with the pixels of this cel. This is the preferred way to replace the cel image, because it generates only one undoable action.

Cel.bounds

local bounds = cel.bounds

Returns the rectangle with the cel bounds (position and size).

Cel.position

local position = cel.position
cel.position = newPosition

Gets or sets the cel position.

Cel.opacity

local opacity = cel.opacity
cel.opacity = newOpacity

Gets or sets the cel opacity. A value from 0 to 255 (which means 0=0% completely transparent, or 255=100% completely opaque).

Cel.zIndex

local zIndex = cel.zIndex
cel.zIndex = newZIndex

Gets or sets the cel z-index value. By default 0, which means "show this cel in the same position as its layer", but can be modified to positive values to move the cel to the front, or negative values to move it to the back.

It offers a way to change the order of layers in one specific frame.

Note: The value is limited to the [-32768,32767] range.

Cel.color

local color = cel.color
cel.color = newColor

Gets or sets the user-defined color of this cel in the timeline.

Cel.data

local data = cel.data
cel.data = newData

Gets or sets the user-defined data related to this cel (a text string).

Cel.properties

Access user-defined and extension-defined properties of this cel.
