Overview

The Behavior class is used to control the 鈥渂ehavior鈥 of components, which roughly correlates to the series of options that you see in the Components dialog under the 鈥渆dit鈥 tab, such as whether it casts shadows, glues to walls, etc.

A Behavior object is accessed from a ComponentDefinition object, not created with a Behavior.new call.

Examples:

# Grab the Behavior object from the first component definition.
model = Sketchup.active_model
definition = model.definitions[0]
behavior = definition.behavior

Instance Method Details

↑ #always_face_camera=(setting) ⇒ Object

The always_face_camera= method is used to set the always_face_camera behavior for a component.

If the always_face_camera behavior is true, a component will always try to orient itself so that the Y axis of the component is facing the camera.

Examples:

model = Sketchup.active_model
behavior = model.definitions[0].behavior
status = behavior.always_face_camera = false

Returns status - the status of the always_face_camera behavior.

Parameters:

  • setting —

    Sets the always_face_camera behavior to true or false.

Returns:

  • status - the status of the always_face_camera behavior.

Version:

  • SketchUp 6.0

↑ #always_face_camera? ⇒ Boolean

The always_face_camera? method is used to retrieve the always_face_camera behavior for a component.

If the always_face_camera behavior is true, then a component will always try to orient itself so that the -Y axis of the component is facing the camera.

Examples:

model = Sketchup.active_model
# Returns a DefinitionList
definitions = model.definitions
path = Sketchup.find_support_file "Bed.skp",
  "Components/Components Sampler/"

begin
  definition = definitions.load path
rescue
  UI.messagebox $!.message
end

behavior = definition.behavior
b = behavior.always_face_camera?
if (b)
  UI.messagebox b
else
  UI.messagebox "Always Face Camera is equal to false"
end
status = behavior.always_face_camera = true
b = behavior.always_face_camera?
if (b)
  UI.messagebox b
else
  UI.messagebox "Failure"
end

Returns:

  • (Boolean) —

    behavior - true if the component is set to always face the camera, false if the component is not set to always face camera.

Version:

  • SketchUp 6.0

↑ #cuts_opening=(setting) ⇒ Object

The cuts_opening= method is used to set the cut opening behavior for a component.

Examples:

model = Sketchup.active_model
behavior = model.definitions[0].behavior
status = behavior.cuts_opening = false
if (status)
  # if status is true, print the status
  UI.messagebox status
else
  # code to respond cuts_opening being false
end

Returns status - the status of the cuts_opening behavior (either true or false)

Parameters:

  • setting —

    Sets the cuts_opening behavior to true or false.

Returns:

  • status - the status of the cuts_opening behavior (either true or false)

Version:

  • SketchUp 6.0

↑ #cuts_opening? ⇒ Boolean

The cuts_opening? method is used to get the status of a component's cut opening behavior.

Examples:

model = Sketchup.active_model
behavior = model.definitions[0].behavior
status = behavior.cuts_opening?
if (status)
  # if status is true, do something
else
  # if status is false, do something else
end

Returns:

  • (Boolean) —

    status - the status of the cuts_opening behavior (either true or false)

Version:

  • SketchUp 6.0

↑ #is2d=(setting) ⇒ Object

The is2d= method is used to set the 2D behavior for a component: whether it can be glued or aligned to a face.

Examples:

model = Sketchup.active_model
behavior = model.definitions[0].behavior
status = behavior.is2d = false
if (status)
  # if status is true, print the status
  UI.messagebox status
else
  # code to respond is2d behavior being false
end

Returns status - the new setting

Parameters:

  • setting —

    Sets the 2D behavior to true or false.

Returns:

  • status - the new setting

Version:

  • SketchUp 6.0

↑ #is2d? ⇒ Boolean

The is2d? method is used to get the 2D behavior for a component: whether it can be glued or aligned to a face.

Examples:

model = Sketchup.active_model
behavior = model.definitions[0].behavior
status = behavior.is2d?
if (status)
  # if status is true, do something
else
  # if status is false, do something else
end

Returns:

  • (Boolean) —

    status - the status of the 2D behavior (either true or false)

Version:

  • SketchUp 6.0

↑ #no_scale_mask=(scale_mask) ⇒ Object

Sets an integer that is really a bit-by-bit description of which scale tool handles are hidden on a given component. This is useful for creating definitions that can only be scaled in particular ways. If a bit contains a a 1, then a certain handle set will be hidden when the user selects the component and activates the Scale tool. Here is the map of which bits control which handles.

  • Bit0: disable scale along red (X),

  • Bit1: disable scale along green (Y),

  • Bit2: disable scale along blue (Z),

  • Bit3: disable scale in red/blue plane (X+Z),

  • Bit4: disable scale in green/blue plane (Y+Z),

  • Bit5: disable scale in red/green plane (X+Y),

  • Bit6: disable scale uniform (from corners) (XYZ).

Note that for 2-dimensional components (such as face-me components), not all of the handles in the list above are even used. Also, if the component you are modifying is already selected with the scale tool, then you or your user must deactivate and reactivate the scale tool for your new behavior to take effect.

Examples:

# Disable the green and red-axes handles by setting bits 1 and 2 to 1.
definition = Sketchup.active_model.definitions[0]
behavior = definition.behavior
behavior.no_scale_mask = (1 << 1) + (1 << 2)

Returns behavior - the Behavior object

Parameters:

  • scale_mask —

    An integer describing which scale tool handles are hidden.

Returns:

  • behavior - the Behavior object

Version:

  • SketchUp 7.0

↑ #no_scale_mask? ⇒ Boolean

The no_scale_mask? method returns an integer that is a bit-by-bit description of which scale tool handles are hidden when the user selects this single component with the scale tool. See the no_scale_mask= method for details on the bit encodings used.

Examples:

definition = Sketchup.active_model.definitions[0]
behavior = definition.behavior
no_scale_mask = behavior.no_scale_mask?

Returns:

  • (Boolean) —

    scale_mask - an integer describing which scale tool handles are hidden.

Version:

  • SketchUp 7.0

↑ #shadows_face_sun=(status) ⇒ Object

The shadows_face_sun= method is used to identify whether the component's shadow will be cast from the component's current position as though the component were facing the sun. See the Component entity within the SketchUp User's guide for more information on this feature.

Examples:

model = Sketchup.active_model
behavior = model.definitions[0].behavior
behavior = behavior.shadows_face_sun = true

Returns behavior - the Behavior object

Parameters:

  • status —

    true if the component's is to be cast from the component's current position as though the component were facing the sun. False to cause the shadow to be cast from the component's current position.

Returns:

  • behavior - the Behavior object

Version:

  • SketchUp 6.0

↑ #shadows_face_sun? ⇒ Boolean

The shadows_face_sun? method is used to determine whether the component's shadow is being cast from the component's current position (as though the component were facing the sun). See the Component entity within the SketchUp User's guide for more information on this feature.

Examples:

model = Sketchup.active_model
# Returns a DefinitionList
definitions = model.definitions
path = Sketchup.find_support_file "Bed.skp",
  "Components/Components Sampler/"
begin
  definition = definitions.load path
rescue
  UI.messagebox $!.message
end

Returns:

  • (Boolean) —

    status - true if the component's is to be cast from the component's current position as though the component were facing the sun. False to cause the shadow to be cast from the component's current position.

  • SketchUp 6.0

↑ #snapto ⇒ Object

The snapto method is used to verify the status of a component's 鈥渟nap to鈥 behavior.

Returns a constant indicating the snapping behavior of the component described by behavior. Snapping behavior is how the x-y plane of a component instance will be snapped against a face. Possible values are:

  • SnapTo_Arbitrary => Snap to any aribrary face,

  • SnapTo_Horizontal => Snap to horizontal face like floors,

  • SnapTo_Vertical => Snap to vertical face like walls,

  • SnapTo_Sloped => Snap to sloped face like sloping roofs.

Examples:

model = Sketchup.active_model
behavior = model.definitions[0].behavior
status = behavior.snapto
if (status)
  # if status is true, do something
else
  # if status is false, do something else
end

Returns:

  • status - the status of the snapto behavior (either true or false)

Version:

  • SketchUp 6.0
