public class FSWaitForFrame
extends FSActionObject

The FSWaitForFrame action instructs the player to wait until the specified frame number has been loaded.

If the frame has been loaded then the actions in the following n actions are executed. This action is most often used to execute a short animation loop that plays until the main part of a movie has been loaded.

Attributes
type Identifies the action when it is encoded. Read-only.
frameNumber The number of the frame to check to see whether it has been loaded.
actionCount The number of actions, following the FSWaitForFrame action that will be executed when the frame has been loaded.

Examples

The following example instructs the Flash Player to wait until the eighth frame of a movie clip has been loaded then to move the time-line to the loaded frame:
 actions.add(new FSWaitForFrame(8, 1));
 actions.add(new FSGotoFrame(8));
 

This method of waiting until a frame has been loaded is considered obsolete. Determining the number of frames loaded using the FramesLoaded property of the Flash player in combination with an FSIf action is now the preferred mechanism:

 FSDoAction actions = new FSDoAction();
 
 actions.add(new FSPush("_root"));
 actions.add(new FSAction(FSAction.GetVariable));
 actions.add(new FSPush(FSPush.FramesLoaded));
 actions.add(new FSAction(FSAction.GetProperty));
 actions.add(new FSPush(8));
 actions.add(new FSAction(FSAction.Less));
 actions.add(new FSIf(-29));
 
 actions.add(new FSGotoFrame(8));
 

History

The FSWaitForFrame class represents the ActionWaitForFrame action of the Macromedia Flash (SWF) File Format Specification. It was introduced in Flash 3.

Constructor Detail

FSWaitForFrame

public FSWaitForFrame(FSCoder coder)
Construct an FSWaitForFrame object, initialising it with values decoded from an encoded object.

Parameters:
coder - an FSCoder containing the binary data.

FSWaitForFrame

public FSWaitForFrame(int aFrameNumber,
                      int anActionCount)
Constructs an FSWaitForFrame object with the specified frame number and the number of actions that will be executed when the frame is loaded.

Parameters:
aFrameNumber - the number of the frame to wait for.
anActionCount - the number of actions to execute.

FSWaitForFrame

public FSWaitForFrame(FSWaitForFrame obj)
Constructs an FSWaitForFrame object by copying values from an existing object.

Parameters:
obj - an FSWaitForFrame object.
Method Detail

getFrameNumber

public int getFrameNumber()
Gets the frame number.

Returns:
the number of the frame to wait for.

getActionCount

public int getActionCount()
Gets the number of actions that will be executed when the specified frame is loaded.

Returns:
the number of actions.

setFrameNumber

public void setFrameNumber(int aNumber)
Sets the frame number.

Parameters:
aNumber - the number of the frame to wait for.

setActionCount

public void setActionCount(int aNumber)
Sets the number of actions to execute if the frame has been loaded. Unlike other actions it is the number of actions that are specified not the number of bytes in memory they occupy.

Parameters:
aNumber - the number of actions to execute.

equals

public boolean equals(java.lang.Object anObject)
Description copied from class: FSActionObject
Returns true if anObject is equal to this one. Objects are considered equal if they would generate identical binary data when they are encoded to a Flash file.

Overrides:
equals in class FSActionObject
Returns:
true if this object would be identical to anObject when encoded.

appendDescription

public void appendDescription(java.lang.StringBuffer buffer,
                              int depth)
Description copied from class: FSTransformObject
AppendDescription is used to present a string description of the object including all nested objects up to a specified depth. This method provide a more controlled way of creating a string representation of an object since large objects such as font or shape definitions can contain dozens of nested objects. The representation of the object is appended to the StringBuffer, showing the name of the class and values of the attributes it contains. If the object contains any attributes that are objects then the object graph will be traversed up to the specified depth. If objects are nested at a level less than specified depth then the full string representation of the object is displayed. For objects at the specified depth only the name of the class is displayed. Any objects below this depth are not displayed.

Specified by:
appendDescription in class FSTransformObject
Parameters:
buffer - a StringBuffer to which the description of each object is appended.
depth - the maximum level of nesting up to which objects will be displayed.

length

public int length(FSCoder coder)
Overrides:
length in class FSActionObject

encode

public void encode(FSCoder coder)
Overrides:
encode in class FSActionObject

decode

public void decode(FSCoder coder)
Overrides:
decode in class FSActionObject
