memberObjRef.preLoad

// JavaScript syntax

memberObjRef.preLoad;

Description

Cast member property; determines whether the digital video cast member specified by

whichCastMember can be preloaded into memory (TRUE) or not (FALSE, default). The TRUE

status has the same effect as selecting Enable Preload in the Digital Video Cast Member

Properties dialog box.

For Flash movie cast members, this property controls whether a Flash movie must load entirely

into RAM before the first frame of a sprite is displayed (

TRUE), or whether the movie can stream

into memory as it plays (

FALSE, default). This property works only for linked Flash movies whose

assets are stored in an external file; it has no effect on members whose assets are stored in the cast.

The

streamMode and bufferSize properties determine how the cast member is streamed into

memory.

This property can be tested and set.

Example

This statement reports in the Message window whether the QuickTime movie Rotating Chair can

be preloaded into memory:

-- Lingo syntax

put(member("Rotating Chair").preload)

// JavaScript syntax

put(member("Rotating Chair").preload);
