RE: FLASH: Movie clips

[David Williamson]

Hi


	As JC said nested loops are a bad thing, but you may want to take

this into account too. The 200,000 action limit is not 200,000 EDITOR

actions but related to PLAYER actions. The .SWF open file format white paper

should give infomation on this. 


In the player a section of script such as this


LOOPWhile (i <= 200,000)

set variable i = i +1

endloop


The simple code can equal near 7 or so actions i belive. 


(infact if you put just this string in a movie and have a text box that

displays i then you will see that the player hit 200,000 actions when i is

equal to 14185 (i think, its a long time since i tried it out.))


The player actually works the SetVariable action as this, or close to it.


get variable i 

add 1 to it 

set variable to the result. 


and when it checks for it in the loop statement it does a similar set of

events


Get Variable i

compare to 200,000


The important thing is that what looks like at maximum 3 actions is

considrably more. The other thing to remember is that Skipping along the

time line WILL NOT Always work. If during the course of an action script you

use a Goto frame action where the rest of the script continues then Flash

may still register the seperate frame and consiquent scripting as part of

the same Action string.


You can test this by using the script


If (i <= 200,000)

goto frame 5

Else

stop


In frame 5 the action

set variable (i = i+1

goto frame 1


if you link up the same text box to display the variable. it crashes way

before i = 200,000


Also Flash 4 will count the number of Nested Function calls. Originally

there was a limit of 32 nested function calls in the player before it

crashed, this may have been raised now. Nested functions are for example


Call (function A)


Function A then has an if Else statement 


If (condition)

call (function B)

Else 

Call (function C)


both Function B and Function C are nested functions.


Some thing else you should avoid is Using a goto frame command in the course

of either a Function Call or a Loop, this seems to Cause the player to get a

bit confused and crash soon after.


hope this clears some things up.


cheers dave

Hi Jason,


If you get the 200,000 error then operations need to be divided up into

different frames. Loop accross Flash frames not totally in one. Loops

within loops are generally not going to work within the same Flash

frame.


There is no limit to nested frames except practical. I just tried a 9

deep MC /a/b/c/d/e/f/g/h/i which Flash 4 displayed completely, so I

selected the path just by clicking and not manually entering it. I was

able to target the top layer without problems. I have done deeper MCs in

Flash 3. Make sure all your MCs are MCs with their behaviors set to MC.
