Empty Strings that will fill with inkey. - 04/16/10 10:03

Hi there,

i got a problem. Maybe it is extrem easy and i just dont get it or it is more complicated.

At the moment i�m creating a login system. It is very simple and just .txt layered.

The first thing i do is create my Strings.

Code:

STRING* id_input = "#10";
STRING* pw_input = "#10";

The i have my input field with inkey function, a login and a register button.

Now what i want is. If player press the register button it should check if mininum 3 characters are typed in. That does not work because my strings are already 10 characters longs even if they dont have any characters in it.

This depends on the "#10" after string creation. So everytime i click register it checks the inputs and says: "yes theres is more than 3 characters." But there isnt.

This is the check code.

Code:

input_check = str_len(id_input);

if(input_check > 2)
{
	// Write ID Data
}
else
{
	error("ID need at least 3 characters.");
}

If i create my strings with this one: ""

I just have one character to type in with inkey.

Now how can i manage it that my strings are all 1 character long as long as there is no inkey input?

Hi,
at the remarks of the inkey function is this:
The str_cursor function can be used to get the current cursor position while the string is edited.
That should be useful to find the latest cursor position. If more than 2 then O.K. (count starts at 1)

But what if the user types in nothing but just moves the cursor three letters to the right? Or what if he types in more than 3 letters, but has to correct the first one, so the cursor end up at the left end?

I rather suggest to check if there is a non-space character at the third letter or later.
