1086 Chapter 14: Properties
visible (sprite)
Usage
sprite(whichSprite).visible
the visible of sprite whichSprite
Description
Sprite property; determines whether the sprite specified by whichSprite is visible (TRUE) or not
(
FALSE). This property affects all sprites in the channel, regardless of their position in the Score.
Note: Setting the visible property of a sprite channel to FALSE makes the sprite invisible and
prevents only the mouse-related events from being sent to that channel. The
beginSprite, endSprite,
prepareFrame, enterFrame, and exitFrame events continue to be sent regardless of the sprite’s
visibility setting. Clicking the Mute button on that channel in the Score, however, will set the
visible
property to
FALSE and prevent all events from being sent to that channel. Muting disables a channel,
while setting a sprite’s
visible property to FALSE merely affects a graphic property.
This property can be tested and set. If set to FALSE, this property will not automatically reset to
TRUE when the sprite ends. You must set the visible property of the sprite to TRUE in order to
see any other members using that channel.
Example
This statement makes sprite 8 visible:
sprite(8).visible = TRUE
visibility
Usage
member(whichCastmember).model(whichModel).visibility
modelObjectReference.visibility
Description
3D property; allows you to get or set the visibility property of the referenced model. This
property determines how the model’s geometry is drawn. It can have one of the following values:
• #none specifies that no polygons are drawn and the model is invisible.
• #front specifies that only those polygons facing the camera are drawn.This method is
referred to as back face culling and optimizes rendering speed. This is the default setting
for the property.
• #back specifies that only those polygons facing away from the camera are drawn. Use this
setting when you want to draw the inside of a model, or for models which are not drawing
correctly, possibly because they were imported from a file format that used a different
handiness value when computing normals.
• #both specifies that both sides of all polygons are drawn.Use this setting when you want to see
the plane regardless of the viewing direction, and for models that are not drawing correctly.
Example
The following statement shows that the visibility property of the model Monster02 is set to
#none. The model is invisible.
put member("3D").model("Monster02").visibility
-- #none
