Description

Function; for Shockwave Audio (SWA) or Flash cast members, indicates whether an error occurred as the cast member streamed into memory and returns a value.

Shockwave Audio cast members have the following possible getError() integer values and corresponding getErrorString() messages:

Flash movie cast members have the following possible getError values:

FALSE—No error occurred.

#memory—There is not enough memory to load the cast member.

#fileNotFound—The file containing the cast member's assets could not be found.

#network—A network error prevented the cast member from loading.

#fileFormat—The file was found, but it appears to be of the wrong type, or an error occurred while reading the file.

#other—Some other error occurred.

When an error occurs as a cast member streams into memory, Director sets the cast member's state property to -1. Use the getError function to determine what type of error occurred.

Example

This handler uses getError to determine whether an error involving the Shockwave Audio cast member Norma Desmond Speaks occurred and displays the appropriate error string in a field if it did:

on exitFrame
	if member("Norma Desmond Speaks").getError() <> 0 then
		member("Display Error Name").text = member("Norma Desmond \ Speaks").getErrorString()
	end if
end

Example

This handler checks to see whether an error occurred for a Flash cast member named Dali, which was streaming into memory. If an error occurred, and it was a memory error, the script uses the unloadCast command to try to free some memory; it then branches the playback head to a frame in the Director movie named Artists, where the Flash movie sprite first appears, so Director can again try to load and play the Flash movie. If something other than an out-of-memory error occurred, the script goes to a frame named Sorry, which explains that the requested Flash movie can't be played.

on CheckFlashStatus 
	errorCheck = member("Dali").getError()
	if errorCheck <> 0 then
		if errorCheck = #memory then
			member("Dali").clearError()
			unloadCast
			go to frame ("Artists")
		else
			go to frame ("Sorry")
		end if
	end if
end
