array.random

Generate a random array of a specified length

Description

Creates a new array object of a specified length, pre-filled with random numbers.

Arguments

length[int]
optional

The length of the generated array.

initial-range[list]
optional

The range of random values to generate. If both values are integers, random integers will be generated, otherwise random floating-point numbers will be generated.

Attributes

mode[int]: 0

Fill Mode Possible values:

0 = 'Repeat'
1 = 'Repeat Last'
2 = 'Repeat Zero'
3 = 'Interpolate (Linear)'

range[atom]: 0 1

The range can be any two numerical values, including negative values. If the range contains a floating-point value, the object will generate floating-point output. Otherwise, it will generate integers.

A single value specifies a range between 0 and the supplied value (or 0 1 if the supplied value is also 0 ).

seed[int]

A seed value for the random number generation. Reseeding the object with the same value will cause the same series of random numbers to be generated. A seed value of 0 will cause a new random seed to be generated.

urn[int]: 0

When generating integers (only), generate all numbers in the specified range before repeating a number. For instance, with a range of 0 5 and a length of 10, a possible result would be [ 3, 4, 0, 1, 2, 1, 3, 2, 0, 4 ] . Note that enabling urn does not automatically cause the object to generate integers -- an integer range also needs to be supplied.

Common Box Attributes

Below is a list of attributes shared by all objects. If you want to change one of these attributes for an object based on the object box, you need to place the word sendbox in front of the attribute name, or use the object's Inspector.

annotation[symbol]

Sets the text that will be displayed in the Clue window when the user moves the mouse over the object.

background[int]: 0

Adds or removes the object from the patcher's background layer. background 1 adds the object to the background layer, background 0 removes it. Objects in the background layer are shown behind all objects in the default foreground layer.

color[4 floats]

Sets the color for the object box outline.

fontface[int]

Sets the type style used by the object. The options are:

plain
bold
italic
bold italic Possible values:

0 = 'regular'
1 = 'bold'
2 = 'italic'
3 = 'bold italic'

fontname[symbol]

Sets the object's font.

fontsize[float]

Sets the object's font size (in points). Possible values:

'8'
'9'
'10'
'11'
'12'
'13'
'14'
'16'
'18'
'20'
'24'
'30'
'36'
'48'
'64'
'72'

hidden[int]: 0

Toggles whether an object is hidden when the patcher is locked.

hint[symbol]

Sets the text that will be displayed in as a pop-up hint when the user moves the mouse over the object in a locked patcher.

ignoreclick[int]: 0

Toggles whether an object ignores mouse clicks in a locked patcher.

jspainterfile[symbol]

You can override the default appearance of a user interface object by assigning a JavaScript file with code for painting the object. The file must be in the search path.

patching_rect[4 floats]: 0. 0. 100. 0.

Sets the position and size of the object in the patcher window.

position[2 floats]
write-only

Sets the object's x and y position in both patching and presentation modes (if the object belongs to its patcher's presentation), leaving its size unchanged.

presentation[int]: 0

Sets whether an object belongs to the patcher's presentation.

presentation_rect[4 floats]: 0. 0. 0. 0.

Sets the x and y position and width and height of the object in the patcher's presentation, leaving its patching position unchanged.

rect[4 floats]
write-only

Sets the x and y position and width and height of the object in both patching and presentation modes (if the object belongs to its patcher's presentation).

size[2 floats]
write-only

Sets the object's width and height in both patching and presentation modes (if the object belongs to its patcher's presentation), leaving its position unchanged.

textcolor[4 floats]

Sets the color for the object's text in RGBA format.

textjustification[int]

Sets the justification for the object's text. Possible values:

0 = 'left'
1 = 'center'
2 = 'right'

varname[symbol]

Sets the patcher's scripting name, which can be used to address the object by name in pattr, scripting messages to thispatcher, and the js object.

Messages

bang

Reprocess previously received arrays and trigger output.

int

Convert an incoming integer to an array, then process as described for the array message.

Arguments:
  • value [int]

  (inlet1)

The length of the generated array.

Arguments:
  • length [int]

float

Convert an incoming floating-point number to an array, then process as described for the array message.

Arguments:
  • value [float]

list

Convert an incoming list to an array, then process as described for the array message.

Arguments:
  • list-value [list]

anything

Convert an incoming list to an array, then process as described for the array message.

Arguments:
  • list-value [list]

array

A new array object will be created at the length specified by the object's first argument, or by a number received in the rightmost inlet. The object will then be filled with random values, as specified by the range and seed.

An incoming array will be used as a new range. As such, only the first two integer and floating-point numbers will be used -- all other data will be interpreted as 0 .

dictionary

Wrap an incoming dictionary object in an array, then process as described for the array message.

Arguments:
  • dictionary-value [list]

string

Wrap a string object in an array, then process as described for the array message.

Arguments:
  • string-value [list]
