variable from a for in loop

[jaydru]

just need to cast it into a variable that has been declared outside of the for loop

string $return[] = {};
for ( $i=0; $i<5; $i++ )
$return[size($return)] = ("pPlane1.f[" + $i + "]");

this is a good example when NOT to use a for in loop.

btw I think its never a good idea. If you want to come back at some point and add something useful to it you will end up doing a regular for loop anyway. set up abbreviations for the for-loop in your IDE and be done

oh, and what James said :)

Ok word! There is absolutely NO need to browse an array like {0,1,2,3,4} in a for-in-loop! :D Its actually a quite good mel-joke.

But I have to disagree: The for-in-loop is very useful!
Writing $variable[$i] all the time is much more work and less clean than $obj for instance.

Furthermore you can do stuff like:for ($obj in `ls -sl`)
...and the `ls -sl` will only be evaluated ONCE! (But note that the thing will break if the command does not return anything. Other than if you pass an empty array!)

Whereas infor($i = 0; $i < size(`ls -sl`); $i++)
...size(`ls -sl`) would be evaluated EACH loop.

however: Of course size is no heavy option. But If you need a count-variable anyways I tend to use the following thing:{
int $index[] = {0,1,2,3,4};
string $faces[];
int $numFaces;

for ($face in $index)
$faces[$numFaces++] = "pPlane1.f[" + $face + "]";

print $faces;
print("$numFaces: " + $numFaces + "\n");
}

No offense james: But asking for the size each loop and having $i with always the same value is very funny as well ;] :beer:

The values at $index[] (0,1,2,3,4) are only sample numbers. i will use the script with other, not continuous numbers. But your replies was helpfull. Now i can correct my code.

Thanks!

For-in loops are far more efficient than for loops.Therefore, when applicable, always prefer for-in.

the fact that python ONLY supports this kind of for-loop is probably a good indication that it is always a good idea. :D ;)
