Default on (keyPress "<num1>")

I made a calculator the other day (in about 30 minutes ) and now I want to make it possible to use the num pad to enter numbers. I've used if Key.IsDown for the arrow keys but nothing else. So can someone tell me how to use the num pad for the calculator

Hi,

You can use a key listener to get all pressed keys. The code below is an example. NumLock would have to be on, I think, for this method to work, otherwise you would have to use a case statement to direct the keycodes, since the output wouldn't have an ascii value.

PHP Code:
//--------------------------------------------------------------------
//key_listen_obj.as for use with keyboard actionscript
//--------------------------------------------------------------------

//create object
key_listen = new Object();
key_info = new Object();

//key listener
key_listen.onKeyDown = function(){
        
key_info.ref Key;
        
key_info.keycode Key.getCode();
        
key_info.ascii Key.getAscii();
        
key_info.string = (String.fromCharCode(key_info.ascii));
        
key_info.number Number(key_info.string);
        
        
/* use traces to test input */
        //trace ("the current key is : " +key_info.keycode)
        //trace ("the current key ascii is : " +key_info.ascii)

        
if ((key_info.keycode != 0) && (key_info.number != undefined)) {
            
// a valid key is pressed 
            
run_calculator_function(key_info.number);
        } else {
            break;
        };
};
