pv

Share data within a patch hierarchy

Description

Creates a value that is shared between objects, but only within a single patcher. Unlike the value object, pv objects that share the same name only share the same value if they are in the same patcher, or one of its subpatches.

Examples

Discussion

The pv also object cannot be the receiver of a message sent remotely by a message box (the first symbol after a semicolon).

Arguments

name [symbol]

Obligatory. The first argument provides an identifying name. All pv objects with that name within the patcher will share the same value.

message [symbol]

Optional

Any message typed in after the first argument initializes the stored contents of the pv object. Note that when two or more pv objects in a patcher file that share the same name are initialized to different values, the one which is initialized last determines the value. Since the order in which pv objects will be initialized cannot be precisely determined, the best practice is to initialize only one of the related pv objects.

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

presentation_rect [4 floats] (default: 0. 0. 0. 0.)

rect [4 floats]

g/s(set)

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]
