I am looking for a file to fill 'array' type 'string'
the declaration of the 'string array':

var test: PoolStringArray = []

and then..
var i: int
i = 1
test [i] = file.get_line ()

But I have this message; invalid set index '1' (on basis: 'PoolStringArray') with value of type 'String'

You get this error because you didn't resize the array. Accessing indexes without giving proper size to the array results in invalid index.

For your use case, I would suggest you use append, which increases size by 1 and adds the line at the end of the array:


In case you know in advance how many lines there is:

test[i] = file.get_line()

Another thing to note: array indexes start from 0, not 1.

okay, and can we define the dimension of 'Array' to the declaration of the variable?

thank you
ps; original your audio story on your site.

You can't declare the size of the array at the same line of creation of the array, it needs a second line:

var lines = []

thank you very much
