When the movie plays back as an applet, the stageTop property is always 0, which is the location

of the left side of the applet.

This function can be tested but not set.

Sprite coordinates are expressed relative to the upper left corner of the Stage.

Example

This statement checks whether the top of the Stage is beyond the top of the screen and calls the

handler upperMonitorProcedure if it is:

if the stageTop < 0 then upperMonitorProcedure

Syntax

member(whichCastmember).modelResource(whichModelResource).

startAngle

modelResourceObjectReference.startAngle

Description

3D property; when used with a model resource whose type is #cylinder or #sphere, this command

allows you to both get and set the

startAngle property of the referenced model resource, as a

floating-point value from 0.0 to 360.0. The default value for this property is 0.0.

The

startAngle property determines the starting sweep angle of the model resource, and works in

conjunction with the

endAngle property to draw spheres and cylinders. For example, if you want

to make a half sphere, set startAngle to 0.0 and endAngle to 180.0.

Example

The following statement sets the startAngle of the model resource Sphere01 to 0.0. If its endAngle

is set to 90, then only one quarter of any model that uses this model resource will appear.

put member("3D World").modelResource("Sphere01").startAngle
