NOT IN FLASH !!!!!!!
"i" on the left means variable with name i
i - means value of this variable
in basic this problem looks like:
10 I = 3
20 IF (I=3) THEN GOTO 100
30 GOTO 20
.
.
100 - there should jump interpreter but with MM logic it's continuing execution and jumps to 20!
that's with basic but I DON'T WANT TO JUMP OVER CODE
In current player is implemented a mechanism of "playhead" - it's OK - it's necessary - interpreter (handler) must know what is the
next frame to play.
After instructions like Goto and Play, Goto and Stop, Stop - handler sets "playhead" and flag "play". It's OK, too.
The question is why the handler continues executing (interpreting) code after these "special" instructions?
For example if you script looks like:
set variable: "i" = 5
if (i>4)
Goto and Stop (40)
end if
if (i>3)
Goto and Stop (30)
end if
if (i>2)
Goto and Stop (20)
end if
if (i>1)
Goto and Stop (10)
end if
Execution should perform "jump" to 40 - no real "jump" - settng playhead to frame 40, displaying current frame, handle code from
object (buttons - events) and should go to displaying frame 40.
BUT IT'S EXECUTING WHOLE CODE AND JUMPS TO 10
There is no word about additional conditions in the docs !
IT'S NO PROBLEM TO MAKE IT WORKING WITH "ELSE" BUT IT SHOULD WORK IN ACTUAL SCRIPT, TOO
Another example with F5 (as seen on screenshoots):
"i" = 3
"j" = 4
"k" = 7
if( i = 3 ) {
j = j + 1
if ( j = 5 ) {
k = k +1
if ( k = 8 ) {
Goto and Stop ( 20 )
} else {
Goto and Stop ( 40 )
}
} else {
Goto and Stop ( 50 )
}
Goto and Stop ( 30 )
}
WHAT FRAME WILL BE NEXT?
"TRANSLATE" THIS CONDITIONS TO "ELSE" WITHOUT BUGS - hard, almost IMPOSSIBLE !
IT HAS IT'S OWN LOGIC ?
Making it in "right" (as in jscript, asp etc) way shouldn't "beat" existing code - because they are (in majority) done with "safe
else" way.
ONCE AGAIN - QUESTIONS
1. Is is necessary to execute code after "goto" ?
2. Shouldn't execution be stopped (only for this scope) ?
3. Do you have code based on "continues execution" ?
4. Do you take care about instructions order in your scripts?
5. Is it clear, what i mean?
