Clearing array values?

by Isaac Barbosa · in Torque Game Builder · 02/15/2007 (6:45 pm) · 7 replies

Hi:

I have clear the values of tons of values inside my array. I have used:

for (%i=0; %i<$NUM_WORDS; %i++)
   $words[%i++] = "";

And it works. I just want to ask if there is another way to do so, or if this is the right way :)

Thanks

@Isaac -- I believe "null" is a valid value, and would actually be the proper way to "clear" something, as "" is an empty string ... though, I'm not 100% sure whether or not TorqueScript evaluates "" to NULL internally or not ...

As for looping, seems the only real way to do it with TorqueScript arrays ...

You can check with a dump() that if you have $array[0] = 2, $array[1] = 3, $array[2] = "", $array[3] = 4

it will show up as

$array0 = 2
$array1 = 3
$array3 = 4

As arrays in torquescript aren't really arrays, there isn't a way to remove/clear them without a loop, as the [] operator is just a concatenation. Setting things to "" will clear them though, and they will no longer be referenced as having values nor will they show up in dump()

I have a feeling that loop only clears half the values though...

@Isaac and David
In TS a null is the same as "". Setting the values to null seems more proper to me, but whatever works.

@James
You can't do a dump() on an array.

@Richard
Yeah, that code sure looks like it is going to clear only every other value!

@Isaac
You probably don't want to increment %i inside the array operator.

@Ben:

This is the working code -no ++ inside the array operator-:

for (%i=0; %i<$NUM_WORDS; %i++)
   $words[%i] = "";

cool. So this is the only way.

@Richard:
Quote:I have a feeling that loop only clears half the values though...

Why that feeling? This is clearing entirely the values in my game... is there a unknow risk clearing array values with this method?

That feeling was due to the extra postfix operator inside the array operator. Your original posted code DOES clear only half the values.

Ah... I never tried it... it was a mistake when copied
