Random Code

[Ravmaster]

number=Math.ceil(Math.random()*2);
if(number==1){
_root.baddy.gotoAndStop(5);
}
if(number==2){
_root.baddy.gotoAndStop(3);
}

can someone tell me whats wrong with this code please...

[InfestedDemon]

typo maybe?

[Nich]

Have you tried tracing your random ouput to see if you are in fact only getting 1's and 2's? I know the code is designed that way but flash can be wierd about these things

[nathan99]

can't you just use the random() function instead to get whole numbers?

number=random(2)+1;
if(number==1){
_root.baddy.gotoAndStop(5);
}
if(number==2){
_root.baddy.gotoAndStop(3);
}

[optixburn]

number=Math.ceil(Math.random()*2);
if(number==1){
_root.baddy.gotoAndStop(5);
}
if(number==2){
_root.baddy.gotoAndStop(3);
}

can someone tell me whats wrong with this code please...

don't use number ... flash might be reading it as a reserved word

also to note that this can still produce a 0 output so that should be taken into consideration.

try this


myNum = Math.ceil(Math.random()*2);
if(myNum == 1){
_root.baddy.gotoAndStop(5);
}else if(myNum == 2){
_root.baddy.gotoAndStop(3);
}else{
// default
_root.baddy.gotoAndStop(3);
}


if this still doesn't work make sure you are linking correctly


_root.any_kind_of_reference_of_a_movieClip._proper ty;


this seems to be a big sourcce of a lot peoples problems not knowing how pathing works

hope this helps

You could always go with the classic randRange they gave out in the Help Files.



function randRange(min:Number, max:Number):Number {
var randomNum:Number = Math.floor(Math.random() * (max - min + 1)) + min;
return randomNum;
}


so all you have to do is...



number=randRange(1,2);
if(number==1){
_root.baddy.gotoAndStop(5);
}
if(number==2){
_root.baddy.gotoAndStop(3);
}

[Ravmaster]

also now this code dont work :'(


_root.main.main.gotoAndStop(1)

[Joppe]

Why are you using math . ceil?


number=Math.random(2)
Math.round(number)
if(number==1){
_root.baddy.gotoAndStop(5);
}
if(number==2){
_root.baddy.gotoAndStop(3);
}


whats wrong with that?

He's using Math.ceil because random doesn't generate 1's and 2's, but numbers with fractions like 0.12342 (Which will become 1 if you 'ceil' it :P)

Just a little cosmetic, but wouldn't a switch statement look alot better ? :P

The only reasons I can think of that make your code NOT work are these :

If you trace 'number' and it's undefined, flash probably wants you to assign a value to number before you use it like

var number:Number = 0;

number = Math.ceil(Math.random()*2);

Other reason could be a naming issue with your movie clip. Try tracing the clip to see if it really exists :)


switch(Math.ceil(Math.random()*2)){
case 1 :
_root.baddy.gotoAndStop(3);
break;
case 2 :
_root.baddy.gotoAndStop(5);
break;
}

[Ravmaster]

ok done that bit works fine now thnx everyone i just need to know why this code dont work,,,


_root.main.main.gotoAndStop(1)

[Ophyr]

Is there a 'main' clip inside a 'main' clip in your root :P Check the instance names I'd say, or do a trace(_root.main.main); to see wether the clip you're accessing exists. You did miss a ; at the end of that line but I'm not sure if Flash is too picky about that :P

[Joppe]

^ Math.random(2) returns an decimal number but you can round it
Math.round() or you could just use random(2) without the Math. thats returns just whole numbers.

[Ravmaster]

i traced the thing and it was found but it still didnt work

[Joppe]

Rav, now it has come to the point when you post your fla..

You're right, I always use Math.random() * value -- thanks :D

[Ravmaster]

Rav, now it has come to the point when you post your fla..

hehe i guess your right :D

http://www.verzend.be/v/6263868/Main.fla.html is that an ok host?

[Joppe]

Ok i'll look at it

[Ravmaster]

thankies ;)
