Re: [flasher] Getting variables from a txt file

[Muzak]

Sorry, that is incorrect. Flash treats variables loaded from a textfile as strings, even if they're numeric values.


So, if you have a1=23&a2=dog&a3=14&a4=cat the the text file loaded into flash:


Flash will return:

a1 + a2 = "23dog";

a1 + a3 = 2314; //and not 37

a2 + a4 = "dogcat";


If you try this:

number(a1) + number(a3)

Flash will indeed return 37


If you'd like to test this - using the variables above in a textfile then do some tracing:


trace ("a1+a2 = "+(a1+a2));

trace ("a1+a3 = "+(a1+a3));

trace ("number(a1)+number(a3) = "+(Number(a1)+Number(a3)));

trace ("a2+a4 = "+(a2+a4));

----------------------------

Returns this in the output window:


a1+a2 = 23dog

a1+a3 = 2314

number(a1)+number(a3) = 37

a2+a4 = dogcat

---------------------------

Also, if you do a 'list variables' in test movie mode you'll get these:

  Variable _level0.a1 = "23"

  Variable _level0.a2 = "dog"

  Variable _level0.a3 = "14"

  Variable _level0.a4 = "cat"

--------------------------

Looks like strings to me :-)
