jit.anim.drive
Description
Animates relative transforms over time with easing. The jit.anim.drive object works in conjunction with jit.anim.node and OpenGL objects to perform this function. Double clicking the object will open a ui mapping dictionary, allowing certain user interface actions to be mapped to animation messages.
Examples
Discussion
UI mapping of key and mouse input is facilitated by editing the ui-map dictionary. Key input is mapped alpha-numeric keys and arrow keys (using up, down, left and right instead of the key symbol). Mouse mapping looks for the following dictionary entries:
Horizontal: mouse_horizontal, mouse_h, mouse_x
Horizontal with button down: mouse_down_horizontal, mouse_down_h, mouse_down_x
Vertical: mouse_vertical, mouse_v, mouse_y
Vertical with button down: mouse_down_vertical, mouse_down_v, mouse_down_y
UI input can be mapped to move, turn and grow messages.
Attributes
active [int]
Indicates if the object is currently animating.
automatic [int]
Enables automatic update messages (default = 1). Requires the targetname object to belong to a valid OpenGL context.
drawto [symbol]
Assign to the named drawing context, allowing for updates to be received automatically.
ease [float]
Set both easein and easeout attributes (default = 1.).
easefunc [symbol]
Determines how the easing is applied (default = linear).
Possible values:
'linear'
'quadratic'
'cubic'
easein [float]
Determines how long it will take (in seconds) for a specific animation message to go from it's current value to the new value (default = 1.). This attribute only affects the move, turn and grow animations.
easeout [float]
Determines how long it will take (in seconds) for a specific animation message to go from it's current value to 0 (default = 1.). This attribute only affects the move, turn and grow animations.
evalreport [int]
Enable/disable the evaluation parameter reporting out the dumpout (default = 0). The report is a 3 element list where each element represents the current evaluation parameters for the moveto, rotateto, and scaleto messages, in that order.
name [symbol]
Specifies the name of the instance (default = UID).
position [3 floats]
The current stored position in 3D space. This attribute is used for the moveto and springto messages (default = 0 0 0).
quat [4 floats]
The current orientation in 3D space, stored as a quaternion value. This attribute is used for the rotateto message (default = 0 0 0 1).
scale [3 floats]
The current stored scale in 3D space. This attribute is used for the scaleto message (default = 1 1 1).
speed [float]
The speed of animations in units per second. (default = 30.)
spring_damp [float]
The dampening amount applied to the spring equation used in the springto message (default = 0.1).
spring_mass [float]
The mass amount applied to the spring equation used in the springto message (default = 1.).
spring_stiff [float]
The stiffness amount applied to the spring equation used in the springto message (default = 0.2).
spring_thresh [float]
The threshold value to determine when the spring simulation is no longer active. Used in the springto message (default = 0.0001).
ui_dict_layout [symbol]
Sets the keyboard layout for the default ui mapping dict when ui_listen is enabled. The value is stored in the application preferences and will affect all future instantiations of jit.anim.drive. To override the default ui mapping see the ui_map and ui_map_clone attributes.
Possible values:
'azerty'
'qwerty'
'qwertz'
'qzerty'
'azerty_v2'
( Includes a keyboard turn around the Z axis )
'qwerty_v2'
( Includes a keyboard turn around the Z axis )
targetname [symbol]
The name of the target object that should be either an OpenGL object, or a jit.anim.node object.
ui_listen [int]
Cause UI mouse and keyboard messages to be received from context window (default = 0). Requires the targetname object to belong to a valid OpenGL context.
ui_map [symbol]
Name associated with the ui mapping dictionary (default = UID). If an existing dictionary is registered to that name, this dictionary will reference the registered dictionary. See the anim.drive.ui.dict example patch for a demonstration.
ui_map_clone [symbol]
The name of a registered dictionary to clone as the UI mapping dictionary. See the anim.drive.ui.dict example patch for a demonstration.
ui_priority [int]
UI priority value (default = 900). When multiple UI objects are listening to the same window, ui_priority determines the order objects receive input. Lower values test first.
Common Box Attributes
annotation [symbol]
Sets the text that will be displayed in the Clue window when the user moves the mouse over the object.
background [int] (default: 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] (default: 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] (default: 0)
Toggles whether an object ignores mouse clicks in a locked patcher.
jspainterfile [symbol]
JS Painter File
patching_rect [4 floats] (default: 0. 0. 100. 0.)
Sets the position and size of the object in the patcher window.
position [2 floats]
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] (default: 0)
Sets whether an object belongs to the patcher's presentation.
presentation_rect [4 floats] (default: 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]
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]
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.
