Automatic actions in MAX
pcontrol: shows or hides windows
can also enable and disable
MIDI objects in a subpatch
window
(messages enable 1 and enable 0

the patch to be controlled needs to
have at least one inlet! (even a dummy
one!)

Graphics
MAX allows the placement of pictures
and geometric shapes. Integers are
used to indicate position, size, priority
and color of images.
graphic object: opens a graphics
window automatically when the patch is
opened (arguments: name of the window
and its position and size - top, left, right,
bottom)

Graphics: drawing shapes,

Drawing shapes in MAX using the
oval/rect/frame/ring objects (arguments:
window name and priority. Shape data is
provided in the inlets)
Pictures: pict object - loads an entire
graphics file and displays it in a
graphics window (arguments: window
name, file name and priority)

Graphics animation
Sprites: objects that draw themselves in
a single space and erase themselves
from their old location when they are
drawn somewhere else (shapes and
images)
Each image in a window is a sprite that can
be moved around by redefining its
coordinates

Graphics in a patch: bpatcher
A bpatcher is like a window in a subpatch - it can be loaded with any
previously saved patch (and that can be
moved inside the bpatcher)! Use the
inspector to load a patch.
Examples: lcd (ball, ellipse), text, or any
sub-patch.
