Is there a better way to capture all keyboard input other than using the key_for_str method?
I note that it does not capture ALL keys, cloning some of them over onto the numberpad and extra buttons?
TIA for any assistance

maybe try "on_anykey" and use the scan code from there? example:
string key_name_str;
function key_Show(_ScanCode)
{
str_for_key(key_name_str,_ScanCode);
error(key_name_str);
}
on_anykey = key_Show;

He means something like getch() which returns the correct char.
The problem with str_for_key is, that it ignores shift, only converts numbers and chars correct,...
So this function is total useless for a real input code.
Maybe with a plugin there is a possible solution, but getch() doesn't work with a plugin and I don't know any other functions like this.

Here's a simple keypress function:
function press_key(num)
{
return(key_pressed(num));
}
I use it by mapping key codes ( See the Manual's Keymapping section for scan codes) to varibles, like this:
var_info upp1 = 72;
var_info leftp1 = 75;
var_info rightp1 = 77;
var_info downp1 = 80;
///when used in a function you'd use it like this:
//in place of:
//if (key_cuu) { ....blah blah blah code }
//you would use:
//if (press_key(upp1)) { ....blah blah blah code }
If you want the key changing code, which includes strings that you can use to show which key is mapped, i'll post it too (the code captures all keyboard stuff and mouse, I should be able to modify it for joystick as well) edit: oh yes, I also have Gamepad mapping which allows you to switch between the Joystick (gamepad) Digital and Analog, if you need that as well.

I guess he want's to make an own inkey function because the standard inkey function is "not so good" to say it harmless ^^
Have you ever tried making an own inkey function using key_for_str?

maby somthing like this
function return_pressed_key()
{
if(key_a){return = 30;}
//until z
if(key_o){return = 11;}
//1-9
if(key_shift){return = 54;}//42
if(mouse_left){return = 280;}
//enz. enz enz
}
"empty"

Currently I am using str_for_key and key_for_str, and have also created a simple load / save, allowing key mapping to be done easily. It just feels a little.... un-robust, with these keys missing. It also has some trouble with special keys and mouse input. So I would very much appreciate some alternative way of doing this. Maybe there is a .DLL that better handles input? @Flits: I am not sure how your code helps, please explain. Sorry for my noobish ness

instead of using strings i use vars and then you can convert it to string ore use lastpressed
the great thing is you can use mouse buttons and yostick buttons

so you do want to be able to change your mapping of keys?

The simplest way to explain it, is by posting my code first. Note I have posted the entire code below, including the read/write of the keymap ini, for persistant settings.

var k_leanRight;
var k_rollLeft;
var k_rollRight;
var k_takeCover;
// Move Varients
var k_sprintMove;
var k_toggleStance;
var k_jumpMove;

The problem is capturing all keys, the key_mapping does not support the numpad keys, unless I am missing something here. It appears that the mapping lists 7,9,1 and 3 as the alt counterparts.... It's also worth throwing into the mix that my keypress approach doesn't seem to be a good approach, and I welcome any suggestions on how to improve / replace it. Really I am trying to get a solid input and then link it to my camera movement and other functionality etc. TIA for any help, and thanks to those who have helped already
