swap/alternate a value for each time used in for loop

[Wick3dParticle]

Hey pbarnes.

Take a look at this loop...and apply it to your needs.
$a[$i] will spit back either 1 or -1 each time, depending on if $i is divisible by 2.


string $selection[] = `ls -sl`;
int $i = 0;
int $a[];
for ($each in $selection){
$i++;

if ($i % 2){
$a[$i] = 1;
}
else {
$a[$i] = -1;
}

print ($a[$i] + "\n");
}




Hope that helps,

hey, well it does help but still not doin what i want

heres what i have
float $offsetY = $myYValue + 0.01;
float $offsetX = $myXValue / 2;
select -cl;
string $bricks[] = `ls "brick*"`;

//dup height
int $i = 0;
int $valueHeight = `intField -q -v myHeight`;
float $offBrickY = $myYValue + 0.02;
int $a[];
select $bricks;
for($i=0; $i<$valueHeight; $i++)
{
if ($i % 2){
$a[$i] = 0;
duplicate -rr; move -r 0 $offBrickY 0;
}
else{
$a[$i] = 1;
}
duplicate -rr; move -r $offsetX $offBrickY 0;
}

but it doesnt come back basicly i want it to go 0 then the variable of $offsetX the 0 ....ect

heres what it looks like with that code

[Wick3dParticle]

if ($i % 2){
$a[$i] = 0;
duplicate -rr; move -r 0 $offBrickY 0;
}
else{
$a[$i] = 1;
}
duplicate -rr; move -r $offsetX $offBrickY 0;
}[/CODE]

but it doesnt come back basicly i want it to go 0 then the variable of $offsetX the 0 ....ect

heres what it looks like with that code

Ok...so you get a value of $a = 0 or 1...but what are you doing with $a?
It doesnt look like you are doing anything with that data.


for example:


if ($i % 2){
$a[$i] = 0;

}
else{
$a[$i] = 1;
}
duplicate -rr;
eval("move -r " + $offsetX + " " + $a[$i] + ";");

}

The code is just to demonstrate how to use the data from $a.

Hope that helps,

soz but im still not getting it


int $i = 0;
int $valueHeight = `intField -q -v myHeight`;
float $offBrickY = $myYValue + 0.02;
int $a[];
select $bricks;
for($i=0; $i<$valueHeight; $i++)
{
if ($i % 2)
{
$a[$i] = 0;
}
else{
$a[$i] = $offsetX;
}
duplicate -rr; move -r $a[$i] $offBrickY 0;
}


but this just makes it go straight up and not alternate,

$a[$i] i have set to the variable of $offsetX which changes depening on the users setting the size of the brick



with the if else - do you only need one duplicate command,
i cant seem to get this to work


cheers

Why don't you post the full script you have there, and explain what exactly you are trying to achieve...and I will try my best to help you from there.

thx for the help i have solved it now

i needed to make the values opposite of each other ie ones pos the other is neg otherwise wen u use 0 it doesnt move back to 0 it just stays in the same place causing the effect you see above
