2.Select the button, find the flash component tag in the Property inspector (on the right of the window), andEventpassmode(Last) Default# PassneverChange# Passalways.

Why does the mouseup in movie not respond?

The order in which Director sends event messages to handler is sprite behavior.-->Cast member script-->Frame Behavior-->Movie script.

Before the four types of handler, there was another kind of things similar to the default handler, such as on mouseupscript. It is a little different from the four types of handler above. After it finishes executing itself, the messages will be forwarded in turn. You can also disable them,Dontpassevent. In the preceding four types of event handler, you must manually add pass () at the end (). For example, if the pass () statement is not written at the end of the On mouseup operation of Sprite, the event ends after processing.

Therefore, handler at all levels, especially system event handler, must be checked whether or notPass ().

How can I determine whether a variable is a list?

Listp (VAL). If Val is list, 1 is returned; otherwise, 0 is returned.

Similarly, integerp (), floatp (), stringp (), and objectp ().

 

How can I determine the list type?

ILK (OBJ). Example

bids = [:]

put ilk (bids)

-- # Proplist

ILK (OBJ) can not only judge the list type, but also output the OBJ type, including integer, String, object, rect, point, color, date, symbol, void, picture, instance, Member, Xtra, script, castlib, Sprite, instance, sound, window, media, timeout, image ..

another method is ilk (OBJ, # type). The returned value is whether obj is of type.
