Try this:

addEventListener(Event.ENTER_FRAME, update);
function update(e:Event):void
{
if((mc1.x == 10 && mc1.y == 10) && (mc2.x == 10 && mc2.y == 10) &&(mc3.x == 10 && mc3.y == 10)){
//do something
}
}

Mmm akunu I'm a as2 learning as3 so a little question: are those brackets needed or they are just for simplicity?

The {,} are needed. They tell flash what is part of the function or of the if statement, the ; are not necessary but helps flash.

Adding to that... the () around the comparisons inside the if function are not mandatory, but it can help a lot for reading

hey everyone! first post! (i'm so proud...lol)

so actually using parenthesis does make a difference in the way that the statement is interpreted. for example:

if( (x==1 && y==1) && z==1 )

in this condition, if if BOTH x=1 AND y=1 the first part results in true - so all of the arguments in this statement must result in true
however:

if( (x==1 || y==1) && z==1 )

in this condition, if EITHER x=1 OR y=1 the first part results in true - so in this case the first part of the condition is only dependent on one of the two values being true.

by surrounding the arguments with parenthesis you are in effect creating a 'sub-condition' or really just an evaluation of the statements inside the parenthesis - actually the 'if' isn't even necessary, try this sometime:

var n:int=1;
trace( (n==1) );

the result of the operation is true - no IFs, ands or butts (lol)

thanks akunu - long time fan, first time caller ... LOL!

Thanks for your help people, you solved my problem;
